Overview ********** The Modus themes are designed for accessible readability. They conform with the highest standard for color contrast between combinations of background and foreground values. For small sized text, this corresponds to the WCAG AAA standard, which specifies a minimum rate of distance in relative luminance of 7:1. The Modus themes consist of eight themes, divided into four subgroups. Main themes ‘modus-operandi’ is the project’s main light theme, while ‘modus-vivendi’ is its dark counterpart. These two themes are part of the project since its inception. They are designed to cover a broad range of needs and are, in the opinion of the author, the reference for what a highly legible “default” theme should look like. Tinted themes ‘modus-operandi-tinted’ and ‘modus-vivendi-tinted’ are variants of the two main themes. They slightly tone down the intensity of the background and provide a bit more color variety. ‘modus-operandi-tinted’ has a set of base tones that are shades of light ochre (earthly colors), while ‘modus-vivendi-tinted’ gives a night sky impression. Deuteranopia themes ‘modus-operandi-deuteranopia’ and its companion ‘modus-vivendi-deuteranopia’ are optimized for users with red-green color deficiency. This means that they do not use red and green hues for color-coding purposes, such as for diff removed and added lines. Instead, they implement colors that are discernible by users with deueteranopia or deuteranomaly (mostly yellow and blue hues). Tritanopia themes ‘modus-operandi-tritanopia’ and its counterpart ‘modus-vivendi-tritanopia’ are optimized for users with blue-yellow color deficiency. The idea is the same as with the deuteranopia variants: color coding relies only on hues that are accessible to people with tritanopia or tritanomaly, namely, shades of red and cyan. To ensure that users have a consistently accessible experience, the themes strive to achieve as close to full face coverage as possible, while still targeting a curated list of well-maintained packages (*note Face coverage::). The overarching objective of this project is to always offer accessible color combinations. There shall never be a compromise on this principle. If there arises an inescapable trade-off between usability and stylistic considerations, we will always opt for the former. Starting with version 0.12.0 and onwards, the themes are built into GNU Emacs. * Menu: * How do the themes look like:: * Learn about the latest changes::  File: modus-themes.info, Node: How do the themes look like, Next: Learn about the latest changes, Up: Overview 1.1 How do the themes look like =============================== Check the web page with the screen shots (https://protesilaos.com/emacs/modus-themes-pictures/). Note that the themes are highly customizable (*note Customization options::).  File: modus-themes.info, Node: Learn about the latest changes, Prev: How do the themes look like, Up: Overview 1.2 Learn about the latest changes ================================== Please refer to the web page with the change log (https://protesilaos.com/emacs/modus-themes-changelog). It is comprehensive and covers everything that goes into every tagged release of the themes.  File: modus-themes.info, Node: Installation, Next: Enable and load, Prev: Overview, Up: Top 2 Installation ************** The Modus themes are distributed with Emacs starting with version 28.1. On older versions of Emacs, they can be installed using Emacs’ package manager or manually from their code repository. There also exist packages for distributions of GNU/Linux. Emacs 28 ships with ‘modus-themes’ version ‘1.6.0’. Emacs 29 includes version ‘3.0.0’. Emacs 30 provides a newer, refactored version that thoroughly refashions how the themes are implemented and customized. Such major versions are not backward-compatible due to the limited resources at the maintainer’s disposal to support multiple versions of Emacs and of the themes across the years. * Menu: * Install manually from source:: * Install from the archives:: * Install on GNU/Linux:: * Dealing with byte compilation errors::  File: modus-themes.info, Node: Install manually from source, Next: Install from the archives, Up: Installation 2.1 Install manually from source ================================ In the following example, we are assuming that your Emacs files are stored in ‘~/.emacs.d’ and that you want to place the Modus themes in ‘~/.emacs.d/modus-themes’. 1. Get the source and store it in the desired path by running the following in the command line shell: $ git clone https://gitlab.com/protesilaos/modus-themes.git ~/.emacs.d/modus-themes 1. Add that path to your known Elisp libraries’ list, by placing this snippet of Emacs Lisp in your init file (e.g. ‘init.el’): (add-to-list 'load-path "~/.emacs.d/modus-themes") The themes are now ready to be used: *note Enable and load::.  File: modus-themes.info, Node: Install from the archives, Next: Install on GNU/Linux, Prev: Install manually from source, Up: Installation 2.2 Install from the archives ============================= The ‘modus-themes’ package is available from the GNU ELPA archive, which is configured by default. Prior to querying any package archive, make sure to update the index, with ‘M-x package-refresh-contents’. Then all you need to do is type ‘M-x package-install’ and specify the ‘modus-themes’. Once installed, the themes are ready to be used: *note Enable and load::.  File: modus-themes.info, Node: Install on GNU/Linux, Next: Dealing with byte compilation errors, Prev: Install from the archives, Up: Installation 2.3 Install on GNU/Linux ======================== The themes are also available from the archives of some distributions of GNU/Linux. These should correspond to a tagged release rather than building directly from the latest Git commit. It all depends on the distro’s packaging policies. * Menu: * Debian 11 Bullseye:: * GNU Guix::  File: modus-themes.info, Node: Debian 11 Bullseye, Next: GNU Guix, Up: Install on GNU/Linux 2.3.1 Debian 11 Bullseye ------------------------ The themes are part of Debian 11 Bullseye. Get them with: sudo apt install elpa-modus-themes They are now ready to be used: *note Enable and load::. NOTE that Debian’s package is severely out-of-date as of this writing 2022-07-24 09:57 +0300.  File: modus-themes.info, Node: GNU Guix, Prev: Debian 11 Bullseye, Up: Install on GNU/Linux 2.3.2 GNU Guix -------------- Users of Guix can get the themes with this command: guix package -i emacs-modus-themes They are now ready to be used: *note Enable and load::.  File: modus-themes.info, Node: Dealing with byte compilation errors, Prev: Install on GNU/Linux, Up: Installation 2.4 Dealing with byte compilation errors ======================================== From time to time, we receive bug reports pertaining to errors with byte compilation. These seldom have to do with faulty code in the themes: it might be a shortcoming of ‘package.el’, some regression in the current development target of Emacs, a misconfiguration in an otherwise exotic setup, and the like. The common solution with a stable version of Emacs is to: 1. Delete the ‘modus-themes’ package. 2. Close the current Emacs session. 3. Install the ‘modus-themes’ again. For those building Emacs directly from source, the solution may involve reverting to an earlier commit in emacs.git. At any rate, if you encounter such an issue please report it: we will either fix the bug on our end if it is truly ours, or help forward it to the relevant upstream maintainer. Whatever you do, please understand that a build failure does not mean we are necessarily doing something wrong. *note Issues you can help with::.  File: modus-themes.info, Node: Enable and load, Next: Customization options, Prev: Installation, Up: Top 3 Enable and load ***************** NOTE that Emacs can load multiple themes, which typically produces undesirable results and undoes the work of the designer. Use the ‘disable-theme’ command if you are trying other themes beside the Modus collection (*note Option for disabling other themes while loading Modus: Disable other themes.). Users of the built-in themes cannot ‘require’ the package as usual because there is no package to speak of. Instead, things are simpler as built-in themes are considered safe. All one needs is to load the theme of their preference by adding either form to their init file: (load-theme 'modus-operandi) ; Light theme (load-theme 'modus-vivendi) ; Dark theme Remember that the Modus themes are six themes (*note Overview::). Adapt the above snippet accordingly. Users of packaged variants of the themes must add a few more lines to ensure that everything works as intended. First, one has to require the main library before loading one of the themes: (require 'modus-themes) One can activate a theme with something like the following expression, replacing ‘modus-operandi’ with their preferred Modus theme: (load-theme 'modus-operandi :no-confirm) Changes to the available customization options must always be evaluated before loading a theme (*note Customization Options: Customization options.). Reload a theme for new changes to take effect. This is how a basic setup could look like (*note The require-theme for built-in Emacs themes: The require-theme for built-in Emacs themes.): ;;; For the built-in themes which cannot use `require'. (require-theme 'modus-themes) ;; Add all your customizations prior to loading the themes. (setq modus-themes-italic-constructs t modus-themes-bold-constructs nil) ;; Load the theme of your choice. (load-theme 'modus-operandi) ;; Optionally define a key to switch between Modus themes. Also check ;; the user option `modus-themes-to-toggle'. (define-key global-map (kbd "") #'modus-themes-toggle) ;;; For packaged versions which must use `require'. (require 'modus-themes) ;; Add all your customizations prior to loading the themes (setq modus-themes-italic-constructs t modus-themes-bold-constructs nil) ;; Load the theme of your choice. (load-theme 'modus-operandi :no-confirm) (define-key global-map (kbd "") #'modus-themes-toggle) *note Sample configuration with and without use-package::. * Menu: * The require-theme for built-in Emacs themes:: * Sample configuration with and without use-package:: * Differences between loading and enabling::  File: modus-themes.info, Node: The require-theme for built-in Emacs themes, Next: Sample configuration with and without use-package, Up: Enable and load 3.1 The ‘require-theme’ for built-in Emacs themes ================================================= The version of the Modus themes that is included in Emacs CANNOT use the standard ‘require’. This is because the built-in themes are not included in the ‘load-path’ (not my decision). The ‘require-theme’ function must be used in this case as a replacement. For example: (require-theme 'modus-themes) ;; All customizations here (setq modus-themes-bold-constructs t modus-themes-italic-constructs t) ;; Maybe define some palette overrides, such as by using our presets (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-intense) ;; Load the theme of choice (built-in themes are always "safe" so they ;; do not need the `no-require' argument of `load-theme'). (load-theme 'modus-operandi) (define-key global-map (kbd "") #'modus-themes-toggle)  File: modus-themes.info, Node: Sample configuration with and without use-package, Next: Differences between loading and enabling, Prev: The require-theme for built-in Emacs themes, Up: Enable and load 3.2 Sample configuration with and without use-package ===================================================== What follows is a variant of what we demonstrate in the previous section (*note Enable and load::). It is common for Emacs users to rely on ‘use-package’ for declaring package configurations in their setup. We use this as an example: ;;; For the built-in themes which cannot use `require'. (use-package emacs :config (require-theme 'modus-themes) ; `require-theme' is ONLY for the built-in Modus themes ;; Add all your customizations prior to loading the themes (setq modus-themes-italic-constructs t modus-themes-bold-constructs nil) ;; Maybe define some palette overrides, such as by using our presets (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-intense) ;; Load the theme of your choice. (load-theme 'modus-operandi) (define-key global-map (kbd "") #'modus-themes-toggle)) ;;; For packaged versions which must use `require'. (use-package modus-themes :ensure t :config ;; Add all your customizations prior to loading the themes (setq modus-themes-italic-constructs t modus-themes-bold-constructs nil) ;; Maybe define some palette overrides, such as by using our presets (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-intense) ;; Load the theme of your choice. (load-theme 'modus-operandi) (define-key global-map (kbd "") #'modus-themes-toggle)) The same without ‘use-package’: (require 'modus-themes) ; OR for the built-in themes: (require-theme 'modus-themes) ;; Add all your customizations prior to loading the themes (setq modus-themes-italic-constructs t modus-themes-bold-constructs nil) ;; Maybe define some palette overrides, such as by using our presets (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-intense) ;; Load the theme of your choice: (load-theme 'modus-operandi :no-confirm) (define-key global-map (kbd "") #'modus-themes-toggle) *note Differences between loading and enabling::. Note: make sure not to customize the variable ‘custom-theme-load-path’ or ‘custom-theme-directory’ after the themes’ package declaration. That will lead to failures in loading the files. If either or both of those variables need to be changed, their values should be defined before the package declaration of the themes. *note Make the themes look like what the maintainer uses::  File: modus-themes.info, Node: Differences between loading and enabling, Prev: Sample configuration with and without use-package, Up: Enable and load 3.3 Differences between loading and enabling ============================================ The reason we recommend ‘load-theme’ instead of the other option of ‘enable-theme’ is that the former does a kind of “reset” on the face specs. It quite literally loads (or reloads) the theme. Whereas the ‘enable-theme’ function simply puts an already loaded theme to the top of the list of enabled items, re-using whatever state was last loaded. As such, ‘load-theme’ reads all customizations that may happen during any given Emacs session: even after the initial setup of a theme. Examples are calls to ‘custom-set-faces’, as well as new values assigned to the options the Modus themes provide (*note Customization Options: Customization options.). Our tests show that ‘enable-theme’ does not read such variables anew, so it might appear to the unsuspecting user that the themes are somehow broken whenever they try to assign a new value to a customization option or some face. This “reset” that ‘load-theme’ brings about does, however, come at the cost of being somewhat slower than ‘enable-theme’. Users who have a stable setup and who seldom update their variables during a given Emacs session, are better off using something like this: (require 'modus-themes) ;; Activate your desired themes here (load-theme 'modus-operandi t t) (load-theme 'modus-vivendi t t) ;; Enable the preferred one (enable-theme 'modus-operandi) *note Toggle themes without reloading them::. *note Sample configuration with and without use-package::. With the above granted, other sections of the manual discuss how to configure custom faces, where ‘load-theme’ is expected, though ‘enable-theme’ could still apply in stable setups: *note Use theme colors in code with modus-themes-with-colors::.  File: modus-themes.info, Node: Customization options, Next: Advanced customization, Prev: Enable and load, Up: Top 4 Customization options *********************** The Modus themes are highly configurable, though they should work well without any further tweaks. We provide a variety of user options. The following code block provides an overview. In addition to those variables, the themes support a comprehensive system of overrides: it can be used to make thoroughgoing changes to the looks of the themes (*note Option for palette overrides: Palette overrides.). We document everything at length in the pages of this manual and also provide ready-to-use code samples. Remember that all customization options must be evaluated before loading a theme (*note Enable and load::). If the theme is already active, it must be reloaded for changes to take effect. ;; In all of the following, WEIGHT is a symbol such as `semibold', ;; `light', `bold', or anything mentioned in `modus-themes-weights'. (setq modus-themes-italic-constructs t modus-themes-bold-constructs nil modus-themes-mixed-fonts t modus-themes-variable-pitch-ui nil modus-themes-custom-auto-reload t modus-themes-disable-other-themes t ;; Options for `modus-themes-prompts' are either nil (the ;; default), or a list of properties that may include any of those ;; symbols: `italic', `WEIGHT' modus-themes-prompts '(italic bold) ;; The `modus-themes-completions' is an alist that reads two ;; keys: `matches', `selection'.

Symbol: ‘modus-themes-custom-auto-reload’ (‘boolean’ type) Possible values: 1. ‘nil’ 2. ‘t’ (default) All theme user options take effect when a theme is loaded. Any subsequent changes require the theme to be reloaded. When this variable has a non-‘nil’ value, any change made via the Custom UI or related functions such as ‘customize-set-variable’ and ‘setopt’ (Emacs 29), will trigger a reload automatically. With a ‘nil’ value, changes to user options have no further consequences: the user must manually reload the theme (*note Enable and load::).  File: modus-themes.info, Node: Disable other themes, Next: Bold constructs, Prev: Custom reload theme, Up: Customization options 4.2 Option for disabling other themes while loading Modus ========================================================= Brief: Disable all other themes when loading a Modus theme. Symbol: ‘modus-themes-disable-other-themes’ (‘boolean’ type) Possible values: 1. ‘nil’ 2. ‘t’ (default) When the value is non-‘nil’, the commands ‘modus-themes-toggle’ and ‘modus-themes-select’, as well as the ‘modus-themes-load-theme’ function, will disable all other themes while loading the specified Modus theme. This is done to ensure that Emacs does not blend two or more themes: such blends lead to awkward results that undermine the work of the designer. When the value is ‘nil’, the aforementioned commands and function will only disable other themes within the Modus collection. This option is provided because Emacs themes are not necessarily limited to colors/faces: they can consist of an arbitrary set of customizations. Users who use such customization bundles must set this variable to a ‘nil’ value.  File: modus-themes.info, Node: Bold constructs, Next: Italic constructs, Prev: Disable other themes, Up: Customization options 4.3 Option for more bold constructs =================================== Brief: Use bold for code syntax highlighting and related. Symbol: ‘modus-themes-bold-constructs’ (‘boolean’ type) Possible values: 1. ‘nil’ (default) 2. ‘t’ The default is to use a bold typographic weight only when it is required. With a non-‘nil’ value (‘t’) display several syntactic constructs in bold weight. This concerns keywords and other important aspects of code syntax. It also affects certain mode line indicators and command prompts. Advanced users may also want to configure the exact attributes of the ‘bold’ face. *note Configure bold and italic faces::.  File: modus-themes.info, Node: Italic constructs, Next: Mixed fonts, Prev: Bold constructs, Up: Customization options 4.4 Option for more italic constructs ===================================== Brief: Use italics for code syntax highlighting and related. Symbol: ‘modus-themes-italic-constructs’ (‘boolean’ type) Possible values: 1. ‘nil’ (default) 2. ‘t’ The default is to not use slanted text forms (italics) unless it is absolutely necessary. With a non-‘nil’ value (‘t’) choose to render more faces in italics. This typically affects documentation strings and code comments. Advanced users may also want to configure the exact attributes of the ‘italic’ face. *note Configure bold and italic faces::.  File: modus-themes.info, Node: Mixed fonts, Next: Command prompts, Prev: Italic constructs, Up: Customization options 4.5 Option for font mixing ========================== Brief: Toggle the use of monospaced fonts for spacing-sensitive constructs (affects font families). Symbol: ‘modus-themes-mixed-fonts’ (‘boolean’ type) Possible values: 1. ‘nil’ (default) 2. ‘t’ When set to non-‘nil’ (‘t’), configure some spacing-sensitive faces like Org tables and code blocks to always inherit from the ‘fixed-pitch’ face. This is to ensure that certain constructs like code blocks and tables remain monospaced even when users opt for a mode that remaps typeface families, such as the built-in ‘M-x variable-pitch-mode’. Otherwise the layout can appear broken, due to how spacing is done. For a consistent experience, user may need to specify the font family of the ‘fixed-pitch’ face. *note Font configurations for Org and others::.  File: modus-themes.info, Node: Command prompts, Next: Completion UIs, Prev: Mixed fonts, Up: Customization options 4.6 Option for command prompt styles ==================================== Brief: Control the style of command prompts (e.g. minibuffer, shell, IRC clients). Symbol: ‘modus-themes-prompts’ (‘choice’ type, list of properties) Possible values are expressed as a list of properties (default is ‘nil’ or an empty list). The list can include any of the following symbols: • ‘italic’ • ‘italic’ • A font weight, which must be supported by the underlying typeface: • ‘thin’ • ‘ultralight’ • ‘extralight’ • ‘light’ • ‘semilight’ • ‘regular’ • ‘medium’ • ‘semibold’ • ‘bold’ • ‘heavy’ • ‘extrabold’ • ‘ultrabold’ The default (a ‘nil’ value or an empty list) means to only use a subtle colored foreground color. The ‘italic’ property adds a slant to the font’s forms (italic or oblique forms, depending on the typeface). The symbol of a font weight attribute such as ‘light’, ‘semibold’, et cetera, adds the given weight to links. Valid symbols are defined in the variable ‘modus-themes-weights’. The absence of a weight means that the one of the underlying text will be used. Combinations of any of those properties are expressed as a list, like in these examples: (bold italic) (italic semibold) The order in which the properties are set is not significant. In user configuration files the form may look like this: (setq modus-themes-prompts '(extrabold italic)) *note Make prompts more or less colorful::.  File: modus-themes.info, Node: Completion UIs, Next: Org mode blocks, Prev: Command prompts, Up: Customization options 4.7 Option for completion framework aesthetics ============================================== Brief: Set the overall style of completion framework interfaces. Symbol: ‘modus-themes-completions’ (‘alist’ type properties) This affects Company, Corfu, Flx, Icomplete/Fido, Ido, Ivy, Orderless, Vertico, and the standard ‘*Completions*’ buffer. The value is an alist of expressions, each of which takes the form of ‘(KEY . LIST-OF-PROPERTIES)’. ‘KEY’ is a symbol, while ‘PROPERTIES’ is a list. Here is a sample, followed by a description of the particularities: (setq modus-themes-completions '((matches . (extrabold underline)) (selection . (semibold italic)))) The ‘matches’ key refers to the highlighted characters that correspond to the user’s input. When its properties are ‘nil’ or an empty list, matching characters in the user interface will have a bold weight and a colored foreground. The list of properties may include any of the following symbols regardless of the order they may appear in: • ‘underline’ to draw a line below the characters; • ‘italic’ to use a slanted font (italic or oblique forms); • The symbol of a font weight attribute such as ‘light’, ‘semibold’, et cetera. Valid symbols are defined in the variable ‘modus-themes-weights’. The absence of a weight means that bold will be used. The ‘selection’ key applies to the current line or currently matched candidate, depending on the specifics of the user interface. When its properties are ‘nil’ or an empty list, it has a subtle gray background, a bold weight, and the base foreground value for the text. The list of properties it accepts is as follows (order is not significant): • ‘underline’ to draw a line below the characters; • ‘italic’ to use a slanted font (italic or oblique forms); • The symbol of a font weight attribute such as ‘light’, ‘semibold’, et cetera. Valid symbols are defined in the variable ‘modus-themes-weights’. The absence of a weight means that bold will be used. Apart from specifying each key separately, a catch-all list is accepted. This is only useful when the desired aesthetic is the same across all keys that are not explicitly referenced. For example, this: (setq modus-themes-completions '((t . (extrabold underline)))) Is the same as: (setq modus-themes-completions '((matches . (extrabold underline)) (selection . (extrabold underline)))) *note Make completion matches more or less colorful::.  File: modus-themes.info, Node: Org mode blocks, Next: Heading styles, Prev: Completion UIs, Up: Customization options 4.8 Option for org-mode block styles ==================================== Brief: Set the overall style of Org code blocks, quotes, and the like. Symbol: ‘modus-themes-org-blocks’ (‘choice’ type) Possible values: 1. ‘nil’ (default) 2. ‘gray-background’ 3. ‘tinted-background’ Option ‘nil’ (the default) means that the block has no background of its own: it uses the one that applies to the rest of the buffer. In this case, the delimiter lines have a gray color for their text, making them look exactly like all other Org properties. Option ‘gray-background’ applies a subtle gray background to the block’s contents. It also affects the begin and end lines of the block as they get another shade of gray as their background, which differentiates them from the contents of the block. All background colors extend to the edge of the window, giving the area a rectangular, “blocky” presentation. If the begin/end lines do not extend in this way, check the value of the Org user option ‘org-fontify-whole-block-delimiter-line’. Option ‘tinted-background’ uses a colored background for the contents of the block. The exact color value will depend on the programming language and is controlled by the variable ‘org-src-block-faces’ (refer to the theme’s source code for the current association list). For this to take effect, the Org buffer needs to be restarted with ‘org-mode-restart’. Code blocks use their major mode’s fontification (syntax highlighting) only when the variable ‘org-src-fontify-natively’ is non-‘nil’. While quote/verse blocks require setting ‘org-fontify-quote-and-verse-blocks’ to a non-‘nil’ value. *note Update Org block delimiter fontification::.  File: modus-themes.info, Node: Heading styles, Next: UI typeface, Prev: Org mode blocks, Up: Customization options 4.9 Option for the headings’ overall style ========================================== Brief: Heading styles with optional list of values per heading level. Symbol: ‘modus-themes-headings’ (‘alist’ type, multiple properties) This is an alist that accepts a ‘(KEY . LIST-OF-VALUES)’ combination. The ‘KEY’ is either a number, representing the heading’s level (0 through 8) or ‘t’, which pertains to the fallback style. The named keys ‘agenda-date’ and ‘agenda-structure’ apply to the Org agenda. Level 0 is a special heading: it is used for what counts as a document title or equivalent, such as the ‘#+title’ construct we find in Org files. Levels 1-8 are regular headings. The ‘LIST-OF-VALUES’ covers symbols that refer to properties, as described below. Here is a complete sample with various stylistic combinations, followed by a presentation of all available properties: (setq modus-themes-headings '((1 . (variable-pitch 1.5)) (2 . (1.3)) (agenda-date . (1.3)) (agenda-structure . (variable-pitch light 1.8)) (t . (1.1)))) Properties: • A font weight, which must be supported by the underlying typeface: • ‘thin’ • ‘ultralight’ • ‘extralight’ • ‘light’ • ‘semilight’ • ‘regular’ • ‘medium’ • ‘semibold’ • ‘bold’ (default) • ‘heavy’ • ‘extrabold’ • ‘ultrabold’ • A floating point as a height multiple of the default or a cons cell in the form of ‘(height . FLOAT)’. By default (a ‘nil’ value for this variable), all headings have a bold typographic weight and use a desaturated text color. A ‘variable-pitch’ property changes the font family of the heading to that of the ‘variable-pitch’ face (normally a proportionately spaced typeface). The symbol of a weight attribute adjusts the font of the heading accordingly, such as ‘light’, ‘semibold’, etc. Valid symbols are defined in the variable ‘modus-themes-weights’. The absence of a weight means that bold will be used by virtue of inheriting the ‘bold’ face. *note Configure bold and italic faces::. A number, expressed as a floating point (e.g. 1.5), adjusts the height of the heading to that many times the base font size. The default height is the same as 1.0, though it need not be explicitly stated. Instead of a floating point, an acceptable value can be in the form of a cons cell like ‘(height . FLOAT)’ or ‘(height FLOAT)’, where FLOAT is the given number. Combinations of any of those properties are expressed as a list, like in these examples: (semibold) (variable-pitch semibold 1.3) (variable-pitch semibold (height 1.3)) ; same as above (variable-pitch semibold (height . 1.3)) ; same as above The order in which the properties are set is not significant. In user configuration files the form may look like this: (setq modus-themes-headings '((1 . (variable-pitch 1.5)) (2 . (1.3)) (agenda-date . (1.3)) (agenda-structure . (variable-pitch light 1.8)) (t . (1.1)))) When defining the styles per heading level, it is possible to pass a non-‘nil’ value (‘t’) instead of a list of properties. This will retain the original aesthetic for that level. For example: (setq modus-themes-headings '((1 . t) ; keep the default style (2 . (semibold 1.2)) (t . (rainbow)))) ; style for all other headings (setq modus-themes-headings '((1 . (variable-pitch 1.5)) (2 . (semibold)) (t . t))) ; default style for all other levels Note that the text color of headings, of their background, and overline can all be set via the overrides. It is possible to have any color combination for any heading level (something that could not be done in older versions of the themes). *note Option for palette overrides: Palette overrides. *note Make headings more or less colorful::.  File: modus-themes.info, Node: UI typeface, Next: Palette overrides, Prev: Heading styles, Up: Customization options 4.10 Option for variable-pitch font in UI elements ================================================== Brief: Toggle the use of proportionately spaced (‘variable-pitch’) fonts in the User Interface. Symbol: ‘modus-themes-variable-pitch-ui’ (‘boolean’ type) Possible values: 1. ‘nil’ (default) 2. ‘t’ This option concerns User Interface elements that are under the direct control of Emacs. In particular: the mode line, header line, tab bar, and tab line. The default is to use the same font as the rest of Emacs, which usually is a monospaced family. With a non-‘nil’ value (‘t’) apply a proportionately spaced typeface. This is done by assigning the ‘variable-pitch’ face to the relevant items. *note Font configurations for Org and others::.  File: modus-themes.info, Node: Palette overrides, Prev: UI typeface, Up: Customization options 4.11 Option for palette overrides ================================= This section describes palette overrides in detail. For a simpler alternative, use the presets we provide (*note Palette override presets::). Each Modus theme specifies a color palette that declares named color values and semantic color mappings: • Named colors consist of a symbol and a string that specifies a hexadecimal RGB value. For example: ‘(blue-warmer "#354fcf")’. • The semantic color mappings associate an abstract construct with a given named color from the palette, like ‘(heading-2 yellow-faint)’. Both elements of the list are symbols, though the ‘cadr’ (value) can be a string that specifies a color, such as ‘(heading-2 "#354fcf")’. Both of those subsets can be overridden, thus refashioning the theme. Overrides are either shared, by being stored in the user option ‘modus-themes-common-palette-overrides’, or they are specific to the theme they name. In the latter case, the naming scheme of each palette variable is ‘THEME-NAME-palette-overrides’, thus yielding: • ‘modus-operandi-palette-overrides’ • ‘modus-operandi-deuteranopia-palette-overrides’ • ‘modus-operandi-tinted-palette-overrides’ • ‘modus-operandi-tritanopia-palette-overrides’ • ‘modus-vivendi-palette-overrides’ • ‘modus-vivendi-deuteranopia-palette-overrides’ • ‘modus-vivendi-tinted-palette-overrides’ • ‘modus-vivendi-tritanopia-palette-overrides’ Theme-specific overrides take precedence over the shared ones. It is strongly advised that shared overrides do NOT alter color values, as those will not be appropriate for both dark and light themes. Common overrides are best limited to the semantic color mappings as those use the color value that corresponds to the active theme (e.g. make the cursor ‘blue-warmer’ in all themes, whatever the value of ‘blue-warmer’ is in each theme). The value of any overrides’ variable must mirror a theme’s palette. Palette variables are named after their theme as ‘THEME-NAME-palette’. For example, the ‘modus-operandi-palette’ is like this: (defconst modus-operandi-palette '( ;;; Basic values (bg-main "#ffffff") (bg-dim "#f0f0f0") (fg-main "#000000") ;; ... (red "#a60000") (red-warmer "#972500") (red-cooler "#a0132f") (red-faint "#7f0000") (red-intense "#d00000") ;; ... ;;;; Mappings ;; ... (cursor fg-main) (builtin magenta-warmer) (comment fg-dim) (constant blue-cooler) (docstring green-faint) (fnname magenta) (keyword magenta-cooler) ;; ... )) The ‘modus-operandi-palette-overrides’ targets the entries that need to be changed. For example, to make the main foreground color a dark gray instead of pure black, use a shade of red for comments, and apply a cyan hue to keywords: (setq modus-operandi-palette-overrides '((fg-main "#333333") (comment red-faint) (keyword cyan-cooler))) Changes take effect upon theme reload (*note Custom reload theme::). Overrides are removed by setting their variable to a ‘nil’ value. The common accented foregrounds in each palette follow a predictable naming scheme: ‘HUE{,-warmer,-cooler,-faint,-intense}’. ‘HUE’ is one of the six basic colors: red, green, blue, yellow, magenta, cyan. Named colors that are meant to be used as backgrounds contain ‘bg’ in their name, such as ‘bg-red-intense’. While special purpose foregrounds that are meant to be combined with such backgrounds, contain ‘fg’ in their name, such as ‘fg-removed’ which complements ‘bg-removed’. Named colors can be previewed, such as with the command ‘modus-themes-list-colors’ (*note Preview theme colors::). For a video tutorial that users of all skill levels can approach, watch: .

Those presets override the default color mappings to amplify, tone down, or refashion the overall coloration of the themes. To make almost all aspects of the themes less intense, use this: ;; Always remember to reload the theme for changes to take effect! (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-faint) With ‘modus-themes-preset-overrides-faint’ the grays are toned down, gray backgrounds are removed from some contexts, and almost all accent colors are desaturated. It makes the themes less attention-grabbing. On the opposite end of the stylistic spectrum, we have this ;; Always remember to reload the theme for changes to take effect! (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-intense) The ‘modus-themes-preset-overrides-intense’ makes many background colors accented instead of gray and increases coloration in a number of places. Colors stand out more and are made easier to spot. For some stylistic variation try the “cooler” and “warmer” presets: ;; This: (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-cooler) ;; Or: (setq modus-themes-common-palette-overrides modus-themes-preset-overrides-warmer) Note that the user is not limited to those presets. The system of overrides we provide makes it possible to tweak the value of each individual named color and to change how values are assigned to semantic color mappings (*note Option for palette overrides: Palette overrides.). Subsequent sections provide examples (*note Stylistic variants using palette overrides::). It is also possible to use those presets as a basis and, for example, add to them code from the subsequent sections of this manual. This is the general idea (extra space for didactic purposes): (setq modus-themes-common-palette-overrides `( ;; From the section "Make the mode line borderless" (border-mode-line-active unspecified) (border-mode-line-inactive unspecified) ;; From the section "Make matching parenthesis more or less intense" (bg-paren-match bg-magenta-intense) (underline-paren-match fg-main) ;; And expand the preset here.

In this section we show how to change diff buffers (e.g. in ‘magit’) to only use color-coded text without any added background. What we basically do is to disable the applicable backgrounds and then intensify the foregrounds. Since the deuteranopia-optimized themes do not use the red-green color coding, we make an extra set of adjustments for them by overriding their palettes directly instead of just using the “common” overrides. ;; Diffs with only foreground colors.

In this section we show how to implement a red+blue color coding for diffs in the themes ‘modus-operandi-deuteranopia’ and ‘modus-vivendi-deuteranopia’. As those themes are optimized for users with red-green color deficiency, they do not use the typical red+green color coding for diffs, defaulting instead to yellow+blue which are discernible. Users with deuteranomaly or, generally, those who like a different aesthetic, can use the following to make diffs use the red+yellow+blue color coding for removed, changed, and added lines respectively. This is achieved by overriding the “changed” and “removed” entries to use the colors of regular ‘modus-operandi’ and ‘modus-vivendi’.

Please help verify and/or expand these findings. ] The graphical version of Emacs can reproduce color values accurately. Whereas things get more tricky when Emacs is used in a terminal emulator, because the terminals’ own capabilities determine the number of colors that may be displayed: the Modus themes don’t look as good in that case. There is, however, a way to instruct supported terminal emulators to use more accurate colors. In a shell prompt type ‘toe -a | grep direct’ to get a list of relevant terminfo entries. There should be items such as ‘xterm-direct’, ‘alacritty-direct’, ‘kitty-direct’. Once you find the one that corresponds to your terminal, call Emacs with an environment variable like ‘TERM=xterm-direct’. Example that can be adapted to shell aliases: TERM=xterm-direct emacsclient -nw Another example that can be bound to a key: TERM=xterm-direct uxterm -e emacsclient -nw  File: modus-themes.info, Node: Range of color with terminal emulators, Next: Preview theme colors, Prev: More accurate colors in terminal emulators, Up: Advanced customization 5.4 Range of color with terminal emulators ========================================== [ This is based on partial information. Please help verify and/or expand these findings. ] When Emacs runs in a non-windowed session its color reproduction capacity is framed or determined by the underlying terminal emulator (*note More accurate colors in terminal emulators::). Emacs cannot produce a color that lies outside the range of what the terminal’s color palette renders possible. This is immediately noticeable when the terminal’s first 16 codes do not include a pure black value for the ‘termcol0’ entry and a pure white for ‘termcol15’. Emacs cannot set the correct background (white for ‘modus-operandi’; black for ‘modus-vivendi’) or foreground (inverse of the background). It thus falls back to the closest approximation, which seldom is appropriate for the purposes of the Modus themes. In such a case, the user is expected to update their terminal’s color palette such as by adapting these resources (*note Preview theme colors::): ! Theme: modus-operandi !

The buffer has a naming scheme that reflects the given choice, like ‘modus-operandi-list-colors’ for the ‘modus-operandi’ theme. The command ‘modus-themes-list-colors-current’ skips the minibuffer selection process and just produces a preview for the current Modus theme. When called with a prefix argument (‘C-u’ with the default key bindings), these commands will show a preview of the palette’s semantic color mappings instead of the named colors. In this context, “named colors” are entries that associate a symbol to a string color value, such as ‘(blue-warmer "#354fcf")’. Whereas “semantic color mappings” associate a named color to a symbol, like ‘(string blue-warmer)’, thus making the theme render all string constructs in the ‘blue-warmer’ color value (*note Option for palette overrides: Palette overrides.). Aliases for those commands are ‘modus-themes-preview-colors’ and ‘modus-themes-preview-colors-current’. Each row shows a foreground and background coloration using the underlying value it references. For example a line with ‘#a60000’ (a shade of red) will show red text followed by a stripe with that same color as a backdrop. The name of the buffer describes the given Modus theme and what the contents are, such as ‘*modus-operandi-list-colors*’ for named colors and ‘=*modus-operandi-list-mappings*’ for the semantic color mappings.  File: modus-themes.info, Node: Per-theme customization settings, Next: Get a single color from the palette, Prev: Preview theme colors, Up: Advanced customization 5.6 Per-theme customization settings ==================================== If you prefer to maintain different customization options between the two themes, it is best you write your own functions that first set those options and then load the relevant theme. The following code does exactly that by simply differentiating the two themes on the choice of bold constructs in code syntax (enabled for one, disabled for the other). (defun my-demo-modus-operandi () (interactive) (setq modus-themes-bold-constructs t) ; ENABLE bold (modus-themes-load-theme 'modus-operandi)) (defun my-demo-modus-vivendi () (interactive) (setq modus-themes-bold-constructs nil) ; DISABLE bold (modus-themes-load-theme 'modus-vivendi)) (defun my-demo-modus-themes-toggle () (if (eq (car custom-enabled-themes) 'modus-operandi) (my-demo-modus-vivendi) (my-demo-modus-operandi))) Then assign ‘my-demo-modus-themes-toggle’ to a key instead of the equivalent the themes provide. For a more elaborate design, it is better to inspect the source code of ‘modus-themes-toggle’ and relevant functions.  File: modus-themes.info, Node: Get a single color from the palette, Next: Use theme colors in code with modus-themes-with-colors, Prev: Per-theme customization settings, Up: Advanced customization 5.7 Get a single color from the palette ======================================= *note Use theme colors in code with modus-themes-with-colors::. The fuction ‘modus-themes-get-color-value’ can be called from Lisp to return the value of a color from the active Modus theme palette. It takea a ‘COLOR’ argument and an optional ‘OVERRIDES’. ‘COLOR’ is a symbol that represents a named color entry in the palette. *note Preview theme colors::. If the value is the name of another color entry in the palette (so a mapping), this function recurs until it finds the underlying color value. With an optional ‘OVERRIDES’ argument as a non-‘nil’ value, it accounts for palette overrides. Else it reads only the default palette. *note Option for palette overrides: Palette overrides. With optional ‘THEME’ as a symbol among ‘modus-themes-items’ (alias ‘modus-themes-collection’), use the palette of that item. Else use the current Modus theme. If ‘COLOR’ is not present in the palette, this function returns the ‘unspecified’ symbol, which is safe when used as a face attribute’s value. An example with ‘modus-operandi’ to show how this function behaves with/without overrides and when recursive mappings are introduced. ;; Here we show the recursion of palette mappings. In general, it is ;; better for the user to specify named colors to avoid possible ;; confusion with their configuration, though those still work as ;; expected. (setq modus-themes-common-palette-overrides '((cursor red) (fg-mode-line-active cursor) (border-mode-line-active fg-mode-line-active))) ;; Ignore the overrides and get the original value. (modus-themes-get-color-value 'border-mode-line-active) ;; => "#5a5a5a" ;; Read from the overrides and deal with any recursion to find the ;; underlying value.

Note that users most probably do not need the following. Just rely on the comprehensive overrides we provide (*note Option for palette overrides: Palette overrides.). Advanced users may want to apply colors from the palette of the active Modus theme in their custom code. The ‘modus-themes-with-colors’ macro supplies those to any form called inside of it. For example: (modus-themes-with-colors (list blue-warmer magenta-cooler fg-added warning variable fg-heading-4)) ;; => ("#354fcf" "#531ab6" "#005000" "#884900" "#005e8b" "#721045") The above return value is for ‘modus-operandi’ when that is the active theme. Switching to another theme and evaluating this code anew will give us the relevant results for that theme (remember that since version 4, the Modus themes consist of six items (*note Overview::)). The same with ‘modus-vivendi’ as the active theme: (modus-themes-with-colors (list blue-warmer magenta-cooler fg-added warning variable fg-heading-4)) ;; => ("#79a8ff" "#b6a0ff" "#a0e0a0" "#fec43f" "#00d3d0" "#feacd0") The ‘modus-themes-with-colors’ has access to the whole palette of the active theme, meaning that it can instantiate both (i) named colors like ‘blue-warmer’ and (ii) semantic color mappings like ‘warning’. We provide commands to inspect those (*note Preview theme colors::). Others sections in this manual show how to use the aforementioned macro (*note Advanced customization::). Because the ‘modus-themes-with-colors’ will most likely be used to customize faces, note that any function that calls it must be run at startup after the theme loads. The same function must also be assigned to the ‘modus-themes-after-load-theme-hook’ for its effects to persist and be updated when switching between Modus themes (e.g. to update the exact value of ‘blue-warmer’ when toggling between ‘modus-operandi’ to ‘modus-vivendi’.  File: modus-themes.info, Node: Do not extend the region background, Next: Add padding to mode line, Prev: Use theme colors in code with modus-themes-with-colors, Up: Advanced customization 5.9 Do not extend the region background ======================================= By the default, the background of the ‘region’ face extends from the end of the line to the edge of the window. To limit it to the end of the line, we need to override the face’s ‘:extend’ attribute. Adding this to the Emacs configuration file will suffice: ;; Do not extend `region' background past the end of the line. (custom-set-faces '(region ((t :extend nil)))) *note Make the region preserve text colors, plus other styles: Make the region preserve text colors plus other styles.  File: modus-themes.info, Node: Add padding to mode line, Next: Remap face with local value, Prev: Do not extend the region background, Up: Advanced customization 5.10 Add padding to mode line ============================= Emacs faces do not have a concept of “padding” for the space between the text and its box boundaries. We can approximate the effect by adding a ‘:box’ attribute, making its border several pixels thick, and using the mode line’s background color for it. This way the thick border will not stand out and will appear as a continuation of the mode line. *note Use theme colors in code with modus-themes-with-colors::. (defun my-modus-themes-custom-faces () (modus-themes-with-colors (custom-set-faces ;; Add "padding" to the mode lines `(mode-line ((,c :box (:line-width 10 :color ,bg-mode-line-active)))) `(mode-line-inactive ((,c :box (:line-width 10 :color ,bg-mode-line-inactive))))))) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-custom-faces) The above has the effect of removing the border around the mode lines. In older versions of the themes, we provided the option for a padded mode line which could also have borders around it. Those were not real border, however, but an underline and an overline. Adjusting the above: (defun my-modus-themes-custom-faces () (modus-themes-with-colors (custom-set-faces ;; Add "padding" to the mode lines `(mode-line ((,c :underline ,border-mode-line-active :overline ,border-mode-line-active :box (:line-width 10 :color ,bg-mode-line-active)))) `(mode-line-inactive ((,c :underline ,border-mode-line-inactive :overline ,border-mode-line-inactive :box (:line-width 10 :color ,bg-mode-line-inactive))))))) ;; ESSENTIAL to make the underline move to the bottom of the box: (setq x-underline-at-descent-line t) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-custom-faces) The reason we no longer provide this option is because it depends on a non-‘nil’ value for ‘x-underline-at-descent-line’. That variable affects ALL underlines, including those of links. The effect is intrusive and looks awkard in prose. As such, the Modus themes no longer provide that option but instead offer this piece of documentation to make the user fully aware of the state of affairs.  File: modus-themes.info, Node: Remap face with local value, Next: Font configurations for Org and others, Prev: Add padding to mode line, Up: Advanced customization 5.11 Remap face with local value ================================ There are cases where we need to change the buffer-local attributes of a face. This might be because we have our own minor mode that re-uses a face for a particular purpose, such as a line selection tool that activates ‘hl-line-mode’, but we wish to keep it distinct from other buffers. This is where ‘face-remap-add-relative’ can be applied and may be combined with ‘modus-themes-with-colors’ to deliver consistent results. *note Use theme colors in code with modus-themes-with-colors::. In this example we will write a simple interactive function that adjusts the background color of the ‘region’ face. This is the sample code: (defvar my-rainbow-region-colors (modus-themes-with-colors `((red . ,bg-red-subtle) (green . ,bg-green-subtle) (yellow . ,bg-yellow-subtle) (blue . ,bg-blue-subtle) (magenta . ,bg-magenta-subtle) (cyan . ,bg-cyan-subtle))) "Sample list of color values for `my-rainbow-region'.") (defun my-rainbow-region (color) "Remap buffer-local attribute of `region' using COLOR." (interactive (list (completing-read "Pick a color: " my-rainbow-region-colors))) (face-remap-add-relative 'region `( :background ,(alist-get (intern color) my-rainbow-region-colors) :foreground ,(face-attribute 'default :foreground)))) When ‘my-rainbow-region’ is called interactively, it prompts for a color to use. The list of candidates is drawn from the car of each association in ‘my-rainbow-region-colors’ (so “red”, “green”, etc.). To extend this principle, we may write wrapper functions that pass a color directly. Those can be useful in tandem with hooks. Consider this example: (defun my-rainbow-region-magenta () (my-rainbow-region 'magenta)) (add-hook 'diff-mode-hook #'my-rainbow-region-magenta) Whenever we enter a ‘diff-mode’ buffer, we now get a magenta-colored region. Perhaps you may wish to generalize those findings in to a set of functions that also accept an arbitrary face. We shall leave the experimentation up to you.  File: modus-themes.info, Node: Font configurations for Org and others, Next: Configure bold and italic faces, Prev: Remap face with local value, Up: Advanced customization 5.12 Font configurations for Org and others =========================================== The themes are designed to optionally cope well with mixed font configurations. This mostly concerns ‘org-mode’ and ‘markdown-mode’, though expect to find it elsewhere like in ‘Info-mode’. *note Option for font mixing: Mixed fonts. In practice it means that the user can safely opt for a more prose-friendly proportionately spaced typeface as their default, while spacing-sensitive elements like tables and inline code always use a monospaced font, by inheriting from the ‘fixed-pitch’ face. Users can try the built-in ‘M-x variable-pitch-mode’ to see the effect in action. To make everything use your desired font families, you need to configure the ‘variable-pitch’ (proportional spacing) and ‘fixed-pitch’ (monospaced) faces respectively. It may also be convenient to set your main typeface by configuring the ‘default’ face the same way. [ The ‘fontaine’ package on GNU ELPA (by Protesilaos) is designed to handle this case. ] Put something like this in your initialization file (also consider reading the doc string of ‘set-face-attribute’): ;; Main typeface (set-face-attribute 'default nil :family "DejaVu Sans Mono" :height 110) ;; Proportionately spaced typeface (set-face-attribute 'variable-pitch nil :family "DejaVu Serif" :height 1.0) ;; Monospaced typeface (set-face-attribute 'fixed-pitch nil :family "DejaVu Sans Mono" :height 1.5) Or employ the ‘face-attribute’ function to read an existing value, such as if you want to make ‘fixed-pitch’ use the font family of the ‘default’ face: (set-face-attribute 'fixed-pitch nil :family (face-attribute 'default :family)) The next section shows how to make those work in a more elaborate setup that is robust to changes between the Modus themes. *note Configure bold and italic faces::. Note the differences in the ‘:height’ property. The ‘default’ face must specify an absolute value, which is the point size × 10. So if you want to use a font at point size ‘11’, you set the height to ‘110’.(1) Whereas every other face must either not specify a height or have a value that is relative to the default, represented as a floating point. If you use an integer, then that means an absolute height. This is of paramount importance: it ensures that all fonts can scale gracefully when using something like the ‘text-scale-adjust’ command which only operates on the base font size (i.e. the ‘default’ face’s absolute height). *note Note for EWW and Elfeed fonts: Note on SHR fonts. ---------- Footnotes ---------- (1) ‘:height’ values do not need to be rounded to multiples of ten: the likes of ‘115’ are perfectly valid—some typefaces will change to account for those finer increments.  File: modus-themes.info, Node: Configure bold and italic faces, Next: Custom Org todo keyword and priority faces, Prev: Font configurations for Org and others, Up: Advanced customization 5.13 Configure bold and italic faces ==================================== The Modus themes do not hardcode a ‘:weight’ or ‘:slant’ attribute in the thousands of faces they cover. Instead, they configure the generic faces called ‘bold’ and ‘italic’ to use the appropriate styles and then instruct all relevant faces that require emphasis to inherit from them. This practically means that users can change the particularities of what it means for a construct to be bold/italic, by tweaking the ‘bold’ and ‘italic’ faces. Cases where that can be useful include: • The default typeface does not have a variant with slanted glyphs (e.g. Fira Mono/Code as of this writing on 2021-07-07), so the user wants to add another family for the italics, such as Hack. • The typeface of choice provides a multitude of weights and the user prefers the light one by default. To prevent the bold weight from being too heavy compared to the light one, they opt to make ‘bold’ use a semibold weight. • The typeface distinguishes between oblique and italic forms by providing different font variants (the former are just slanted versions of the upright forms, while the latter have distinguishing features as well). In this case, the user wants to specify the font that applies to the ‘italic’ face. To achieve those effects, one must first be sure that the fonts they use have support for those features. It then is a matter of following the instructions for all typeface tweaks. *note Font configurations for Org and others::. In this example, we set the default font family to Fira Code, while we choose to render italics in the Hack typeface (obviously you need to pick fonts that work well together): (set-face-attribute 'default nil :family "Fira Code" :height 110) (set-face-attribute 'italic nil :family "Hack") And here we play with different weights, using Source Code Pro: (set-face-attribute 'default nil :family "Source Code Pro" :height 110 :weight 'light) (set-face-attribute 'bold nil :weight 'semibold) To reset the font family, one can use this: (set-face-attribute 'italic nil :family 'unspecified) To ensure that the effects persist after switching between the Modus themes (such as with ‘M-x modus-themes-toggle’), the user needs to write their configurations to a function and pass it to the ‘modus-themes-after-load-theme-hook’. This is necessary because themes set the styles of faces upon activation, overriding prior values where conflicts occur between the previous and the current states (otherwise changing themes would not be possible). *note A theme-agnostic hook for theme loading::. This is a minimal setup to preserve font configurations across theme load phases. For a more permanent setup, it is better to rely on the ‘custom-set-faces’ function: ‘set-face-attribute’ works just fine, though it probably is better suited for quick previews or for smaller scale operations (‘custom-set-faces’ follows the format used in the source code of the themes, which can make it easier to redefine faces in bulk). ;; our generic function (defun my-modes-themes-bold-italic-faces () (set-face-attribute 'default nil :family "Source Code Pro" :height 110) (set-face-attribute 'bold nil :weight 'semibold)) ;; or use this if you configure a lot of face and attributes and ;; especially if you plan to use `modus-themes-with-colors', as shown ;; elsewhere in the manual (defun my-modes-themes-bold-italic-faces () (custom-set-faces '(default ((t :family "Source Code Pro" :height 110))) '(bold ((t :weight semibold))))) ;; and here is the hook (add-hook 'modus-themes-after-load-theme-hook #'my-modes-themes-bold-italic-faces) *note Use theme colors in code with modus-themes-with-colors::.  File: modus-themes.info, Node: Custom Org todo keyword and priority faces, Next: Custom Org emphasis faces, Prev: Configure bold and italic faces, Up: Advanced customization 5.14 Custom Org todo keyword and priority faces =============================================== Users of ‘org-mode’ have the option to configure various keywords and priority cookies to better match their workflow. User options are ‘org-todo-keyword-faces’ and ‘org-priority-faces’. As those are meant to be custom faces, it is futile to have the themes guess what each user wants to use, which keywords to target, and so on. Instead, we can provide guidelines on how to customize things to one’s liking with the intent of retaining the overall aesthetic of the themes. Please bear in mind that the end result of those is not controlled by the active Modus theme but by how Org maps faces to its constructs. Editing those while ‘org-mode’ is active requires re-initialization of the mode with ‘M-x org-mode-restart’ for changes to take effect. Let us assume you wish to visually differentiate your keywords. You have something like this: (setq org-todo-keywords '((sequence "TODO(t)" "|" "DONE(D)" "CANCEL(C)") (sequence "MEET(m)" "|" "MET(M)") (sequence "STUDY(s)" "|" "STUDIED(S)") (sequence "WRITE(w)" "|" "WROTE(W)"))) You could then use a variant of the following to inherit from a face that uses the styles you want and also to preserve the attributes applied by the ‘org-todo’ face (in case there is a difference between the two): (setq org-todo-keyword-faces '(("MEET" . (:inherit (bold org-todo))) ("STUDY" . (:inherit (warning org-todo))) ("WRITE" . (:inherit (shadow org-todo))))) This will refashion the keywords you specify, while letting the other items in ‘org-todo-keywords’ use their original styles, which are defined in the ‘org-todo’ and ‘org-done’ faces. If you want back the defaults, try specifying just the ‘org-todo’ face: (setq org-todo-keyword-faces '(("MEET" . org-todo) ("STUDY" . org-todo) ("WRITE" . org-todo))) Or set ‘org-todo-keyword-faces’ to ‘nil’. When you inherit from multiple faces, you need to do it the way it is shown further above. The order is significant: the first entry is applied on top of the second, overriding any attributes that are explicitly set for both of them: any attribute that is not specified is not overridden, so, for example, if ‘org-todo’ has a background and a foreground, while ‘font-lock-type-face’ only has a foreground, the merged face will include the background of the former and the foreground of the latter. If you do not want to blend multiple faces, you only specify one by name without parentheses or an ‘:inherit’ keyword. A pattern of ‘keyword . face’ will suffice. Both approaches can be used simultaneously, as illustrated in this configuration of the priority cookies: (setq org-priority-faces '((?A . (:inherit (bold org-priority))) (?B . org-priority) (?C . (:inherit (shadow org-priority))))) To find all the faces that are loaded in your current Emacs session, use ‘M-x list-faces-display’. Try ‘M-x describe-variable’ as well and then specify the name of each of those Org variables demonstrated above. Their documentation strings will offer you further guidance. Recall that the themes let you retrieve a color from their palette. Do it if you plan to control face attributes. *note Check color combinations: Measure color contrast.  File: modus-themes.info, Node: Custom Org emphasis faces, Next: Update Org block delimiter fontification, Prev: Custom Org todo keyword and priority faces, Up: Advanced customization 5.15 Custom Org emphasis faces ============================== Org provides the user option ‘org-emphasis-alist’ which associates a character with a face, list of faces, or face attributes. The default specification of that variable looks like this: (setq org-emphasis-alist '(("*" bold) ("/" italic) ("_" underline) ("=" org-verbatim verbatim) ("~" org-code verbatim) ("+" (:strike-through t)))) With the exception of ‘org-verbatim’ and ‘org-code’ faces, everything else uses the corresponding type of emphasis: a bold typographic weight, or italicised, underlined, and struck through text. The best way for users to add some extra attributes, such as a foreground color, is to define their own faces and assign them to the given emphasis marker/character. This is a custom face that extends the standard ‘bold’ face with a red foreground value (so it colorises the text in addition to the bold weight): (defface my-org-emphasis-bold '((default :inherit bold) (((class color) (min-colors 88) (background light)) :foreground "#a60000") (((class color) (min-colors 88) (background dark)) :foreground "#ff8059")) "My bold emphasis for Org.") This face definition reads as follows: • Always inherit the ‘bold’ face (*note Configure bold and italic faces::). • For versions of Emacs that support at least 88 colors (graphical Emacs, for example) and use a light background, apply the ‘#a60000’ value. • For the same kind of Emacs that has a dark background use the ‘#ff8059’ color instead. Same principle for how to extend ‘italic’ and ‘underline’ with, for example, green and yellow hues, respectively: (defface my-org-emphasis-italic '((default :inherit italic) (((class color) (min-colors 88) (background light)) :foreground "#005e00") (((class color) (min-colors 88) (background dark)) :foreground "#44bc44")) "My italic emphasis for Org.") (defface my-org-emphasis-underline '((default :inherit underline) (((class color) (min-colors 88) (background light)) :foreground "#813e00") (((class color) (min-colors 88) (background dark)) :foreground "#d0bc00")) "My underline emphasis for Org.") In the case of a strike-through effect, we have no generic face to inherit from, so we can write it as follows to also change the foreground to a more subtle gray: (defface my-org-emphasis-strike-through '((default :strike-through t) (((class color) (min-colors 88) (background light)) :foreground "#505050") (((class color) (min-colors 88) (background dark)) :foreground "#a8a8a8")) "My strike-through emphasis for Org.") Or we can just change the color of the line that strikes through the text to, for example, a shade of red: (defface my-org-emphasis-strike-through '((((class color) (min-colors 88) (background light)) :strike-through "#972500") (((class color) (min-colors 88) (background dark)) :strike-through "#ef8b50")) "My strike-through emphasis for Org.") It is possible to combine those effects: (defface my-org-emphasis-strike-through '((((class color) (min-colors 88) (background light)) :strike-through "#972500" :foreground "#505050") (((class color) (min-colors 88) (background dark)) :strike-through "#ef8b50" :foreground "#a8a8a8")) "My strike-through emphasis for Org.") One may inspect the variables ‘modus-themes-operandi-colors’ and ‘modus-themes-vivendi-colors’ for possible color values. Or call the command ‘modus-themes-list-colors’ to show a buffer that previews each entry in the palette. *note Visualize the active Modus theme’s palette: Preview theme colors. Once we have defined the faces we need, we must update the ‘org-emphasis-alist’. Given that ‘org-verbatim’ and ‘org-code’ are already styled by the themes, it probably is best not to edit them: (setq org-emphasis-alist '(("*" my-org-emphasis-bold) ("/" my-org-emphasis-italic) ("_" my-org-emphasis-underline) ("=" org-verbatim verbatim) ("~" org-code verbatim) ("+" my-org-emphasis-strike-through))) That’s it! For changes to take effect in already visited Org files, invoke ‘M-x org-mode-restart’.  File: modus-themes.info, Node: Update Org block delimiter fontification, Next: Measure color contrast, Prev: Custom Org emphasis faces, Up: Advanced customization 5.16 Update Org block delimiter fontification ============================================= As noted in the section about ‘modus-themes-org-blocks’, Org contains a variable that determines whether the block’s begin and end lines are extended to the edge of the window (*note Option for org-mode block styles: Org mode blocks.). The variable is ‘org-fontify-whole-block-delimiter-line’. Users who change the style of Org blocks from time to time may prefer to automatically update delimiter line fontification, such as with the following setup: (defun my-modus-themes-org-fontify-block-delimiter-lines () "Match `org-fontify-whole-block-delimiter-line' to theme style. Run this function at the post theme load phase, such as with the `modus-themes-after-load-theme-hook'." (if (eq modus-themes-org-blocks 'gray-background) (setq org-fontify-whole-block-delimiter-line t) (setq org-fontify-whole-block-delimiter-line nil))) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-org-fontify-block-delimiter-lines) Then ‘M-x org-mode-restart’ for changes to take effect, though manual intervention can be circumvented by tweaking the function thus: (defun my-modus-themes-org-fontify-block-delimiter-lines () "Match `org-fontify-whole-block-delimiter-line' to theme style. Run this function at the post theme load phase, such as with the `modus-themes-after-load-theme-hook'." (if (eq modus-themes-org-blocks 'gray-background) (setq org-fontify-whole-block-delimiter-line t) (setq org-fontify-whole-block-delimiter-line nil)) (when (derived-mode-p 'org-mode) (font-lock-flush)))  File: modus-themes.info, Node: Measure color contrast, Next: Load theme depending on time of day, Prev: Update Org block delimiter fontification, Up: Advanced customization 5.17 Measure color contrast =========================== The themes provide the functions ‘modus-themes-wcag-formula’ and ‘modus-themes-contrast’. The former is a direct implementation of the WCAG formula: . It calculates the relative luminance of a color value that is expressed in hexadecimal RGB notation. While the latter function is just a convenient wrapper for comparing the relative luminance between two colors. In practice, one needs to work only with ‘modus-themes-contrast’. It accepts two color values and returns their contrast ratio. Values range from 1 to 21 (lowest to highest). The themes are designed to always be equal or higher than 7 for each combination of background and foreground that they use (this is the WCAG AAA standard—the most demanding of its kind). A couple of examples (rounded numbers): ;; Pure white with pure green (modus-themes-contrast "#ffffff" "#00ff00") ;; => 1.37 ;; That is an outright inaccessible combo ;; Pure black with pure green (modus-themes-contrast "#000000" "#00ff00") ;; => 15.3 ;; That is a highly accessible combo It does not matter which color value comes first. The ratio is always the same. If one does not wish to read all the decimal points, it is possible to try something like this: (format "%0.2f" (modus-themes-contrast "#000000" "#00ff00")) While it is fine to perform such calculations on a case-by-case basis, it is preferable to implement formulas and tables for more demanding tasks. Such instruments are provided by ‘org-mode’ or ‘orgtbl-mode’, both of which are built into Emacs. Below is such a table that derives the contrast ratio of all colors in the first column (pure red, green, blue) relative to the color specified in the first row of the second column (pure white) and rounds the results: | | #ffffff | |---------+---------| | #ff0000 | 4.00 | | #00ff00 | 1.37 | | #0000ff | 8.59 | #+tblfm: $2='(modus-themes-contrast $1 @1$2);%0.2f To measure color contrast one needs to start from a known value. This typically is the background. The Modus themes define an expanded palette in large part because certain colors are only meant to be used in combination with some others. Consult the source code for the minutia and relevant commentary. Such knowledge may prove valuable while attempting to customize the theme’s color palette.  File: modus-themes.info, Node: Load theme depending on time of day, Next: Backdrop for pdf-tools, Prev: Measure color contrast, Up: Advanced customization 5.18 Load theme depending on time of day ======================================== While we do provide ‘modus-themes-toggle’ to manually switch between the themes, users may also set up their system to perform such a task automatically at sunrise and sunset. This can be accomplished by specifying the coordinates of one’s location using the built-in ‘solar.el’ and then configuring the ‘circadian’ package: (use-package solar ; built-in :config (setq calendar-latitude 35.17 calendar-longitude 33.36)) (use-package circadian ; you need to install this :ensure t :after solar :config (setq circadian-themes '((:sunrise . modus-operandi) (:sunset . modus-vivendi))) (circadian-setup))  File: modus-themes.info, Node: Backdrop for pdf-tools, Next: Toggle themes without reloading them, Prev: Load theme depending on time of day, Up: Advanced customization 5.19 Backdrop for pdf-tools =========================== Most PDF files use a white background for their page, making it impossible to discern the file’s boundaries in the buffer while using the Modus Operandi theme. To introduce a distinction between the buffer’s backdrop and the PDF page’s background, the former must be rendered as some shade of gray. Ideally, ‘pdf-tools’ would provide a face that the themes could support directly, though this does not seem to be the case for the time being. We must thus employ the face remapping technique that is documented elsewhere in this document to change the buffer-local value of the ‘default’ face. *note Remap face with local value::. To remap the buffer’s backdrop, we start with a function like this one: (defun my-pdf-tools-backdrop () (modus-themes-with-colors (face-remap-add-relative 'default `(:background ,bg-dim)))) (add-hook 'pdf-tools-enabled-hook #'my-pdf-tools-backdrop) The idea is to assign that function to a hook that gets called when ‘pdf-tools’ renders the document: ‘pdf-tools-enabled-hook’. This is enough when you only use one theme. However it has the downside of setting the background color value only at render time. In other words, the face remapping function does not get evaluated anew whenever the theme changes, such as upon invoking ‘M-x modus-themes-toggle’. To have our face remapping adapt gracefully while switching between the Modus themes, we need to also account for the current theme and control the activation of ‘pdf-view-midnight-minor-mode’. To which end we arrive at something like the following, which builds on the above example: (defun my-pdf-tools-backdrop () (modus-themes-with-colors (face-remap-add-relative 'default `(:background ,bg-dim)))) (defun my-pdf-tools-midnight-mode-toggle () (when (derived-mode-p 'pdf-view-mode) (if (eq (car custom-enabled-themes) 'modus-vivendi) (pdf-view-midnight-minor-mode 1) (pdf-view-midnight-minor-mode -1)) (my-pdf-tools-backdrop))) (defun my-pdf-tools-themes-toggle () (mapc (lambda (buf) (with-current-buffer buf (my-pdf-tools-midnight-mode-toggle))) (buffer-list))) (add-hook 'pdf-tools-enabled-hook #'my-pdf-tools-midnight-mode-toggle) (add-hook 'modus-themes-after-load-theme-hook #'my-pdf-tools-themes-toggle) With those in place, PDFs have a distinct backdrop for their page, while buffers with major-mode as ‘pdf-view-mode’ automatically switches to dark mode when ‘modus-themes-toggle’ is called.  File: modus-themes.info, Node: Toggle themes without reloading them, Next: A theme-agnostic hook for theme loading, Prev: Backdrop for pdf-tools, Up: Advanced customization 5.20 Toggle themes without reloading them ========================================= Users who have a stable setup and who only ever need to toggle between the themes without triggering a full reload, are better off defining their own command which calls ‘enable-theme’ instead of ‘load-theme’: (defun my-modus-themes-toggle () "Toggle between `modus-operandi' and `modus-vivendi' themes. This uses `enable-theme' instead of the standard method of `load-theme'. The technicalities are covered in the Modus themes manual." (interactive) (pcase (modus-themes--current-theme) ('modus-operandi (progn (enable-theme 'modus-vivendi) (disable-theme 'modus-operandi))) ('modus-vivendi (progn (enable-theme 'modus-operandi) (disable-theme 'modus-vivendi))) (_ (error "No Modus theme is loaded; evaluate `modus-themes-load-themes' first")))) *note Differences between loading and enabling::. Recall that ‘modus-themes-toggle’ uses ‘load-theme’.  File: modus-themes.info, Node: A theme-agnostic hook for theme loading, Next: Use more spacious margins or padding in Emacs frames, Prev: Toggle themes without reloading them, Up: Advanced customization 5.21 A theme-agnostic hook for theme loading ============================================ The themes are designed with the intent to be useful to Emacs users of varying skill levels, from beginners to experts. This means that we try to make things easier by not expecting anyone reading this document to be proficient in Emacs Lisp or programming in general. Such a case is with the use of ‘modus-themes-after-load-theme-hook’, which runs after the ‘modus-themes-load-theme’ function (used by the command ‘modus-themes-toggle’). We recommend using that hook for advanced customizations, because (1) we know for sure that it is available once the themes are loaded, and (2) anyone consulting this manual, especially the sections on enabling and loading the themes, will be in a good position to benefit from that hook. Advanced users who have a need to switch between the Modus themes and other items will find that such a hook does not meet their requirements: it only works with the Modus themes and only with the aforementioned functions. A theme-agnostic setup can be configured thus: (defvar after-enable-theme-hook nil "Normal hook run after enabling a theme.") (defun run-after-enable-theme-hook (&rest _args) "Run `after-enable-theme-hook'." (run-hooks 'after-enable-theme-hook)) (advice-add 'enable-theme :after #'run-after-enable-theme-hook) This creates the ‘after-enable-theme-hook’ and makes it run after each call to ‘enable-theme’, which means that it will work for all themes and also has the benefit that it does not depend on functions such as ‘modus-themes-toggle’ and the others mentioned above. ‘enable-theme’ is called internally by ‘load-theme’, so the hook works everywhere. The downside of the theme-agnostic hook is that any functions added to it will likely not be able to benefit from macro calls that read the active theme, such as ‘modus-themes-with-colors’. Not all Emacs themes have the same capabilities. In this document, we cover ‘modus-themes-after-load-theme-hook’ though the user can replace it with ‘after-enable-theme-hook’ should they need to (provided they understand the implications).  File: modus-themes.info, Node: Use more spacious margins or padding in Emacs frames, Next: Custom hl-todo colors, Prev: A theme-agnostic hook for theme loading, Up: Advanced customization 5.22 Use more spacious margins or padding in Emacs frames ========================================================= [ UPDATE 2023-06-25: Instead of following these instructions, you can simply install my ‘spacious-padding’ package from GNU ELPA. It implements the padding and provides relevant user options. ] By default, Emacs frames try to maximize the number of characters that fit in the current visible portion of the buffer. Users may prefer to have some extra padding instead. This can make Emacs frames look more pleasant, but also make it easier to identify the currently active window. The way to implement such padding is two-fold: 1. In the ‘early-init.el’ file instruct Emacs to use a higher value for the ‘internal-border-width’ of all frames, as well as for the ‘right-divider-width’. The former concerns the outer boundaries of Emacs frames, while the latter pertains to dividers between Emacs windows. 2. Make the relevant faces invisible by changing the value of their relevant attributes to that of the current theme’s main background. The parameters of Emacs frames are specified in the variables ‘initial-frame-alist’ and ‘default-frame-alist’. The “initial frame” refers to the first frame that appears on Emacs startup. The “default” refers to the fallback values that apply to all other frames that Emacs creates (unless those are explicitly overridden by a bespoke ‘make-frame’ call). In detail, first we use the same values for the two frame alist variables: ;; This must go in the early-init.el so that it applies to the initial ;; frame. (dolist (var '(default-frame-alist initial-frame-alist)) (add-to-list var '(right-divider-width . 20)) (add-to-list var '(internal-border-width . 20))) What the ‘dolist’ does is to call ‘add-to-list’ for the two variables we specify there. This economizes on typing. Then we define a function that makes the relevant faces invisible. The reason we do this with a function is so we can hook it to the “post load” phase of a theme, thus applying the new background value (otherwise you keep the old background, which likely means that the faces will no longer be invisible). (defun my-modus-themes-invisible-dividers () "Make window dividers invisible. Add this to the `modus-themes-post-load-hook'." (let ((bg (face-background 'default))) (custom-set-faces `(fringe ((t :background ,bg :foreground ,bg))) `(window-divider ((t :background ,bg :foreground ,bg))) `(window-divider-first-pixel ((t :background ,bg :foreground ,bg))) `(window-divider-last-pixel ((t :background ,bg :foreground ,bg)))))) (add-hook 'modus-themes-post-load-hook #'my-modus-themes-invisible-dividers) The above will work only for themes that belong to the Modus family. For users of Emacs version 29 or higher, there exists a theme-agnostic hook that takes a function with one argument—that of the theme—and calls in the the “post enable” phase of theme loading. Here is the above snippet, with the necessary tweaks: (defun my-modus-themes-invisible-dividers (_theme) "Make window dividers for THEME invisible." (let ((bg (face-background 'default))) (custom-set-faces `(fringe ((t :background ,bg :foreground ,bg))) `(window-divider ((t :background ,bg :foreground ,bg))) `(window-divider-first-pixel ((t :background ,bg :foreground ,bg))) `(window-divider-last-pixel ((t :background ,bg :foreground ,bg)))))) (add-hook 'enable-theme-functions #'my-modus-themes-invisible-dividers) Users of older versions of Emacs can read the entry herein about defining their own theme-agnostic hook (*note A theme-agnostic hook for theme loading::).  File: modus-themes.info, Node: Custom hl-todo colors, Next: Add support for solaire-mode, Prev: Use more spacious margins or padding in Emacs frames, Up: Advanced customization 5.23 Custom hl-todo colors ========================== The ‘hl-todo’ package provides the user option ‘hl-todo-keyword-faces’: it specifies a pair of keyword and corresponding color value. The Modus themes configure that option in the interest of legibility. While this works for our purposes, users may still prefer to apply their custom values, in which case the following approach is necessary: (defun my-modus-themes-hl-todo-faces () (setq hl-todo-keyword-faces '(("TODO" . "#ff0000") ("HACK" . "#ffff00") ("XXX" . "#00ffff") ("NOTE" . "#ff00ff")))) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-hl-todo-faces) Or include a ‘let’ form, if needed: (defun my-modus-themes-hl-todo-faces () (let ((red "#ff0000") (blue "#0000ff")) (setq hl-todo-keyword-faces `(("TODO" . ,blue) ("HACK" . ,red) ("XXX" . ,red) ("NOTE" . ,blue))))) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-hl-todo-faces) Normally, we do not touch user options, though this is an exception: otherwise the defaults are not always legible.  File: modus-themes.info, Node: Add support for solaire-mode, Prev: Custom hl-todo colors, Up: Advanced customization 5.24 Add support for solaire-mode ================================= The ‘solaire-mode’ package dims the background of what it considers ancillary “UI” buffers, such as the minibuffer and Dired buffers. The Modus themes used to support Solaire on the premise that the user was (i) opting in to it, (ii) understood why certain buffers were more gray, and (iii) knew what other adjustments had to be made to prevent broken visuals (e.g. the default style of the ‘modus-themes-completions’ uses a subtle gray background for the selection, which with Solaire becomes practically invisible). However, the assumption that users opt in to this feature does not always hold true. There are cases where it is enabled by defaultsuch as in the popular Doom Emacs configuration. Thus, the unsuspecting user who loads ‘modus-operandi’ or ‘modus-vivendi’ without the requisite customizations is getting a sub-par experience; an experience that we did not intend and cannot genuinely fix. Because the Modus themes are meant to work everywhere, we cannot make an exception for Doom Emacs and/or Solaire users. Furthermore, we shall not introduce hacks, such as by adding a check in all relevant faces to be adjusted based on Solaire or whatever other package. Hacks of this sort are unsustainable and penalize the entire userbase. Besides, the themes are built into Emacs and we must keep their standard high. The fundamental constraint with Solaire is that Emacs does not have a real distinction between “content” and “UI” buffers. For themes to work with Solaire, they need to be designed around that package. Such is an arrangement that compromises on our accessibility standards and/or hinders our efforts to provide the best possible experience while using the Modus themes. As such, ‘solaire-mode’ is not—and will not be—supported by the Modus themes (or any other of my themes, for that matter). Users who want it must style the faces manually. Below is some sample code, based on what we cover at length elsewhere in this manual: *note Advanced customization::. *note Use theme colors in code with modus-themes-with-colors::. (defun my-modus-themes-custom-faces () (modus-themes-with-colors (custom-set-faces `(solaire-default-face ((,c :inherit default :background ,bg-dim :foreground ,fg-dim))) `(solaire-line-number-face ((,c :inherit solaire-default-face :foreground ,fg-unfocused))) `(solaire-hl-line-face ((,c :background ,bg-active))) `(solaire-org-hide-face ((,c :background ,bg-dim :foreground ,bg-dim)))))) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-custom-faces) As always, re-load the theme for changes to take effect.

The idea for this approach is that the weekend should serve as a subtle warning that no work is supposed to be done on that day, per the design of traditional calendars. Users who prefer all days to look the same can configure the variable ‘calendar-weekend-days’ to either use gray of weekdays or the faint red of weekends uniformly. ;; All are treated like weekdays (gray color) (setq calendar-weekend-days nil) ;; All are treated like weekends (red-faint color) (setq calendar-weekend-days (number-sequence 0 6)) ;; The default marks the Saturday and Sunday as the weekend (setq calendar-weekend-days '(0 6)) For changes to take effect, the Calendar buffer needs to be generated anew.  File: modus-themes.info, Node: Note on git-gutter in Doom Emacs, Next: Note on php-mode multiline comments, Prev: Note on calendarel weekday and weekend colors, Up: Notes on individual packages 7.2 Note on git-gutter in Doom Emacs ==================================== The ‘git-gutter’ and ‘git-gutter-fr’ packages default to drawing bitmaps for the indicators they display (e.g. bitmap of a plus sign for added lines). In Doom Emacs, these bitmaps are replaced with contiguous lines which may look nicer, but require a change to the foreground of the relevant faces to yield the desired color combinations. Since this is Doom-specific, we urge users to apply changes in their local setup. Below is some sample code, based on what we cover at length elsewhere in this manual: *note Advanced customization::. *note Use theme colors in code with modus-themes-with-colors::. (defun my-modus-themes-custom-faces () (modus-themes-with-colors (custom-set-faces ;; Make foreground the same as background for a uniform bar on ;; Doom Emacs. ;; ;; Doom should not be implementing such hacks because themes ;; cannot support them: ;; . `(git-gutter-fr:added ((,c :foreground ,bg-added-fringe))) `(git-gutter-fr:deleted ((,c :foreground ,bg-removed-fringe))) `(git-gutter-fr:modified ((,c :foreground ,bg-changed-fringe)))))) (add-hook 'modus-themes-after-load-theme-hook #'my-modus-themes-custom-faces) As always, re-load the theme for changes to take effect.

This seems to make all comments use the appropriate face: (defun my-multine-comments () (setq-local c-doc-face-name 'font-lock-comment-face)) (add-hook 'php-mode-hook #'my-multine-comments) As always, re-load the theme for changes to take effect.

Users may consider this unnecessary or excessive. To outright disable the effect, use this (buffers need to be generated anew): (setq compilation-message-face nil) If some element of differentiation is still desired, a good option is to render the affected text with the ‘italic’ face: (setq compilation-message-face 'italic) *note Configure bold and italic faces::.

To guarantee consistent results with the Modus themes, we suggest some tweaks to the default styles, such as in this minimal setup: (use-package dimmer :config (setq dimmer-fraction 0.3) (setq dimmer-adjustment-mode :foreground) (setq dimmer-use-colorspace :rgb) (dimmer-mode 1)) Of the above, we strongly recommend the RGB color space because it is the one that remains faithful to the hueness of the colors used by the themes. Whereas the default CIELAB space has a tendency to distort colors in addition to applying the dim effect, which can be somewhat disorienting. The value of the ‘dimmer-fraction’ has been selected empirically. Users might prefer to tweak it further (increasing it makes the dim effect more pronounced). Changing the ‘dimmer-adjustment-mode’ is a matter of preference. Though because the Modus themes use black and white as their base colors, any other value for that variable will turn the main background gray. This inadvertently leads to the opposite of the intended utility of this package: it draws too much attention to unfocused windows.  File: modus-themes.info, Node: Note on display-fill-column-indicator-mode, Next: Note on highlight-parenthesesel, Prev: Note on dimmerel, Up: Notes on individual packages 7.7 Note on display-fill-column-indicator-mode ============================================== The ‘display-fill-column-indicator-mode’ uses a typographic character to draw its line. This has the downside of creating a dashed line. The dashes are further apart depending on how tall the font’s glyph height is and what integer the ‘line-spacing’ is set to. At the theme level we eliminate this effect by making the character one pixel tall: the line is contiguous. Users who prefer the dashed line are advised to change the ‘fill-column-indicator’ face, as explained elsewhere in this document. For example: (modus-themes-with-colors (custom-set-faces `(fill-column-indicator ((,c :foreground ,bg-active))))) *note Use theme colors in code with modus-themes-with-colors::. To make the line thicker, set the height to be equal to the base font size instead of the one pixel we use. This is done by specifying a rate instead of an absolute number, as in ‘:height 1.0’ versus ‘:height 1’. For example: (modus-themes-with-colors (custom-set-faces `(fill-column-indicator ((,c :height 1.0 :background ,bg-inactive :foreground ,bg-inactive)))))  File: modus-themes.info, Node: Note on highlight-parenthesesel, Next: Note on mmm-modeel background colors, Prev: Note on display-fill-column-indicator-mode, Up: Notes on individual packages 7.8 Note on highlight-parentheses.el ==================================== The ‘highlight-parentheses’ package provides contextual coloration of surrounding parentheses, highlighting only those which are around the point. The package expects users to customize the applicable colors on their own by configuring certain variables. To make the Modus themes work as expected with this, we need to use some of the techniques that are discussed at length in the various “Do-It-Yourself” (DIY) sections, which provide insight into the more advanced customization options of the themes. *note Advanced customization::. In the following example, we are assuming that the user wants to (i) re-use color variables provided by the themes, (ii) be able to retain their tweaks while switching between ‘modus-operandi’ and ‘modus-vivendi’, and (iii) have the option to highlight either the foreground of the parentheses or the background as well. We start by defining our own variable, which will serve as a toggle between foreground and background coloration styles: (defvar my-highlight-parentheses-use-background t "Prefer `highlight-parentheses-background-colors'.") Then we can update our preference with this: ;; Set to nil to disable backgrounds. (setq my-highlight-parentheses-use-background nil) To re-use colors from the themes, we must wrap our code in the ‘modus-themes-with-colors’ macro. Our implementation must interface with the variables ‘highlight-parentheses-background-colors’ and/or ‘highlight-parentheses-colors’. So we can have something like this (the doc string of ‘modus-themes-with-colors’ explains where the names of the colors can be found): (modus-themes-with-colors ;; Our preference for setting either background or foreground ;; styles, depending on `my-highlight-parentheses-use-background'. (if my-highlight-parentheses-use-background ;; Here we set color combinations that involve both a background ;; and a foreground value. (setq highlight-parentheses-background-colors (list bg-cyan-intense bg-magenta-intense bg-green-intense bg-yellow-intense) highlight-parentheses-colors (list cyan magenta green yellow)) ;; And here we pass only foreground colors while disabling any ;; backgrounds. (setq highlight-parentheses-colors (list green-intense magenta-intense blue-intense red-intense) highlight-parentheses-background-colors nil))) ;; Include this if you also want to make the parentheses bold: (set-face-attribute 'highlight-parentheses-highlight nil :inherit 'bold) ;; Our changes must be evaluated before enabling the relevant mode, so ;; this comes last. (global-highlight-parentheses-mode 1) For our changes to persist while switching between the Modus themes, we need to include them in a function which can then get passed to ‘modus-themes-after-load-theme-hook’. This is the complete implementation: ;; Configurations for `highlight-parentheses': (require 'highlight-parentheses) (defvar my-highlight-parentheses-use-background t "Prefer `highlight-parentheses-background-colors'.") (setq my-highlight-parentheses-use-background nil) ; Set to nil to disable backgrounds (defun my-modus-themes-highlight-parentheses () (modus-themes-with-colors ;; Our preference for setting either background or foreground ;; styles, depending on `my-highlight-parentheses-use-background'. (if my-highlight-parentheses-use-background ;; Here we set color combinations that involve both a background ;; and a foreground value.

(setq highlight-parentheses-colors (list green-intense magenta-intense blue-intense red-intense) highlight-parentheses-background-colors nil))) ;; Include this if you also want to make the parentheses bold: (set-face-attribute 'highlight-parentheses-highlight nil :inherit 'bold) ;; Our changes must be evaluated before enabling the relevant mode, so ;; this comes last.

The idea is that they must not interfere with existing fontification. Those background colors need to be distinct from each other, such as an unambiguous red juxtaposed with a clear blue. While this design may be internally consistent with the raison d’être of that library, it inevitably produces inaccessible color combinations. There are two competing goals at play: 1. Legibility of the text, understood as the contrast ratio between the background and the foreground. 2. Semantic precision of each face which entails faithfulness to color-coding of the underlying background. As the Modus themes are designed with the express purpose of conforming with the first point, we have to forgo the apparent color-coding of the background elements. Instead we use subtle colors that do not undermine the legibility of the affected text while they still offer a sense of added context. Users who might prefer to fall below the minimum 7:1 contrast ratio in relative luminance (the accessibility target we conform with), can opt to configure the relevant faces on their own. *note Use theme colors in code with modus-themes-with-colors::. This example uses more vivid background colors, though it comes at the very high cost of degraded legibility.

Instead of highlighting the syntactic constructs, it applies color to different levels of depth in the code structure. As ‘prism.el’ offers a broad range of customizations, we cannot style it directly at the theme level: that would run contrary to the spirit of the package. Instead, we may offer preset color schemes. Those should offer a starting point for users to adapt to their needs. In the following code snippets, we employ the ‘modus-themes-with-colors’ macro: *note Use theme colors in code with modus-themes-with-colors::. These are the minimum recommended settings with 16 colors: (setq prism-num-faces 16) (prism-set-colors :desaturations '(0) ; do not change---may lower the contrast ratio :lightens '(0) ; same :colors (modus-themes-with-colors (list fg-main magenta cyan-cooler magenta-cooler blue magenta-warmer cyan-warmer red-cooler green fg-main cyan yellow blue-warmer red-warmer green-cooler yellow-faint))) With 8 colors: (setq prism-num-faces 8) (prism-set-colors :desaturations '(0) ; do not change---may lower the contrast ratio :lightens '(0) ; same :colors (modus-themes-with-colors (list blue magenta magenta-cooler cyan-cooler fg-main blue-warmer red-cooler cyan))) And this is with 4 colors, which produces results that are the closest to the themes’ default aesthetic: (setq prism-num-faces 4) (prism-set-colors :desaturations '(0) ; do not change---may lower the contrast ratio :lightens '(0) ; same :colors (modus-themes-with-colors (list blue magenta magenta-cooler green-warmer))) If you need to apply desaturation and lightening, you can use what the ‘prism.el’ documentation recommends, like this (adapting to the examples with the 4, 8, 16 colors): (prism-set-colors :desaturations (cl-loop for i from 0 below 16 collect (* i 2.5)) :lightens (cl-loop for i from 0 below 16 collect (* i 2.5)) :colors (modus-themes-with-colors (list fg-main cyan-cooler magenta-cooler magenta)))  File: modus-themes.info, Node: Note on company-mode overlay pop-up, Next: Note on ERC escaped color sequences, Prev: Note for prism, Up: Notes on individual packages 7.11 Note on company-mode overlay pop-up ======================================== By default, the ‘company-mode’ pop-up that lists completion candidates is drawn using an overlay. This creates alignment issues every time it is placed above a piece of text that has a different height than the default. The solution recommended by the project’s maintainer is to use an alternative front-end for drawing the pop-up which draws child frames instead of overlays.(1)(2) Also consider the ‘corfu’ package. ---------- Footnotes ---------- (1) (2)  File: modus-themes.info, Node: Note on ERC escaped color sequences, Next: Note on powerline or spaceline, Prev: Note on company-mode overlay pop-up, Up: Notes on individual packages 7.12 Note on ERC escaped color sequences ======================================== The built-in IRC client ‘erc’ has the ability to colorize any text using escape sequences that start with ‘^C’ (inserted with ‘C-q C-c’) and are followed by a number for the foreground and background.(1) Possible numbers are 0-15, with the first entry being the foreground and the second the background, separated by a comma. Like this ‘^C1,6’. The minimum setup is this: (add-to-list 'erc-modules 'irccontrols) (setq erc-interpret-controls-p t erc-interpret-mirc-color t) As this allows users the chance to make arbitrary combinations, it is impossible to guarantee a consistently high contrast ratio. All we can we do is provide guidance on the combinations that satisfy the accessibility standard of the themes: Modus Operandi Use foreground color 1 for all backgrounds from 2-15. Like so: ‘C-q C-c1’ where ‘N’ is the background. Modus Vivendi Use foreground color 0 for all backgrounds from 2-13. Use foreground ‘1’ for backgrounds 14, 15. Colors 0 and 1 are white and black respectively. So combine them together, if you must. ---------- Footnotes ---------- (1) This page explains the basics, though it is not specific to Emacs:  File: modus-themes.info, Node: Note on powerline or spaceline, Next: Note on SHR colors, Prev: Note on ERC escaped color sequences, Up: Notes on individual packages 7.13 Note on powerline or spaceline =================================== Both Powerline and Spaceline package users will likely need to use the command ‘powerline-reset’ whenever they make changes to their themes and/or mode line setup.

This is controlled by the user option ‘ement-room-prism’ and can be disabled with: (setq ement-room-prism nil) The contrast ratio of these colors is governed by another user option: ‘ement-room-prism-minimum-contrast’. By default, it is set to 6 which is slightly below our nominal target. Try this instead: (setq ement-room-prism-minimum-contrast 7) With regard to fonts, Ement depends on ‘shr’ (*note Note on SHR fonts::). Since we are here, here is an excerpt from Ement’s source code: (defcustom ement-room-prism-minimum-contrast 6 "Attempt to enforce this minimum contrast ratio for user faces.

The logo has the effect of enlarging the height of the line, which negatively impacts the shape of those buttons. Disabling the logo fixes the problem: (setq notmuch-show-logo nil)  File: modus-themes.info, Node: Note on goto-address-mode faces, Prev: Note on the Notmuch logo, Up: Notes on individual packages 7.19 Note on goto-address-mode faces ==================================== The built-in ‘goto-address-mode’ uses heuristics to identify URLs and email addresses in the current buffer. It then applies a face to them to change their style. Some packages, such as ‘notmuch’, use this minor-mode automatically. The faces are not declared with ‘defface’, meaning that it is better that the theme does not modify them. The user is thus encouraged to consider including (or equivalent) this in their setup: (setq goto-address-url-face 'link goto-address-url-mouse-face 'highlight goto-address-mail-face 'link goto-address-mail-mouse-face 'highlight) My personal preference is to set ‘goto-address-mail-face’ to ‘nil’, as it otherwise adds too much visual noise to the buffer (email addresses stand out more, due to the use of the uncommon ‘@’ character but also because they are often enclosed in angled brackets).  File: modus-themes.info, Node: Frequently Asked Questions, Next: Contributing, Prev: Notes on individual packages, Up: Top 8 Frequently Asked Questions **************************** In this section we provide answers related to some aspects of the Modus themes’ design and application. * Menu: * Is the contrast ratio about adjacent colors?:: * What does it mean to avoid exaggerations?:: * Why are colors mostly variants of blue, magenta, cyan?: Why are colors mostly variants of blue magenta cyan?. * What is the best setup for legibility?:: * Are these color schemes?:: * Port the Modus themes to other platforms?::  File: modus-themes.info, Node: Is the contrast ratio about adjacent colors?, Next: What does it mean to avoid exaggerations?, Up: Frequently Asked Questions 8.1 Is the contrast ratio about adjacent colors? ================================================ The minimum contrast ratio in relative luminance that the themes conform with always refers to any given combination of background and foreground colors. If we have some blue colored text next to a magenta one, both against a white background, we do not mean to imply that blue:magenta is 7:1 in terms of relative luminance. Rather, we state that blue:white and magenta:white each are 7:1 or higher. The point of reference is always the background. Because colors have about the same minimum distance in luminance from their backdrop, they necessarily are fairly close to each other in this measure. A possible blue:magenta combination would naturally be around 1:1 in contrast of the sort here considered. To differentiate between sequential colors, we rely on hueness by mapping contrasting hues to adjacent constructs, while avoiding exaggerations. A blue next to a magenta can be told apart regardless of their respective contrast ratio against their common background. Exceptions would be tiny characters in arguably not so realistic cases, such as two dots drawn side-by-side which for some reason would need to be colored differently. They would still be legible though, which is the primary objective of the Modus themes.  File: modus-themes.info, Node: What does it mean to avoid exaggerations?, Next: Why are colors mostly variants of blue magenta cyan?, Prev: Is the contrast ratio about adjacent colors?, Up: Frequently Asked Questions 8.2 What does it mean to avoid exaggerations? ============================================= The Modus themes are designed with restraint, so that their default looks do not overdo it with the application of color. *note Customization Options: Customization options. This is the non-quantifiable aspect of the themes’ design: the artistic part, if you will. There are a lot of cases where color can be used inconsiderately, without accounting for layout, typographic, or other properties of the presentation. For example, two headings with distinct markers, such as leading asterisks in Org buffers, do not have to have highly contrasting hues between them in order to be told apart: the added element of contrast in hueness does not contribute significantly more to the distinction between the headings than colors whose hues are relatively closer to each other in the color space. Exaggerations can be hard to anticipate or identify. Multiple shades of blue and magenta in the same context may not seem optimal: one might think that it would be better to use highly contrasting hues to ensure that all colors stand out, such as by placing blue next to yellow, next to magenta, and green. That would, however, be a case of design for its own sake; a case where color is being applied without consideration of its end results in the given context. Too many contrasting hues in close proximity force an erratic rate to how the eye jumps from one piece of text to the next. Whereas multiple shades of, say, blue and magenta can suffice to tell things apart and avoid excess coloration: a harmonious rhythm.  File: modus-themes.info, Node: Why are colors mostly variants of blue magenta cyan?, Next: What is the best setup for legibility?, Prev: What does it mean to avoid exaggerations?, Up: Frequently Asked Questions 8.3 Why are colors mostly variants of blue, magenta, cyan? ========================================================== Due to the innate properties of color, some options are better than others for the accessibility purposes of the themes, the stylistic consistency between ‘modus-operandi’ and ‘modus-vivendi’, and the avoidance of exaggerations in design. *note What does it mean to avoid exaggerations?:: What we describe as color is a function of three distinct channels of light: red, green, blue. In hexadecimal RGB notation, a color value is read as three pairs of red, green, and blue light: ‘#RRGGBB’. Of those three, the most luminant is green, while the least luminant is blue. The three basic colors represent each of the channels of light. They can be intermixed to give us six colors: red and green derive yellow, green and blue make cyan, red and blue turn into magenta. We can test the luminance of each of those against white and black to get a sense of how not all colors are equally good for accessibility (white is ‘#ffffff’, which means that all three light channels are fully luminated, while black is ‘#000000’ meaning that no light is present (notwithstanding display technology)). | Name | | #ffffff | #000000 | |---------+---------+---------+---------| | red | #ff0000 | 4.00 | 5.25 | | yellow | #ffff00 | 1.07 | 19.56 | | green | #00ff00 | 1.37 | 15.30 | | cyan | #00ffff | 1.25 | 16.75 | | blue | #0000ff | 8.59 | 2.44 | | magenta | #ff00ff | 3.14 | 6.70 | *note Measure color contrast::. By reading this table we learn that every color that has a high level of green light (green, yellow, cyan) is virtually unreadable against a white background and, conversely, can be easily read against black. We can then infer that red and blue, in different combinations, with green acting as calibrator for luminance, will give us fairly moderate colors that pass the 7:1 target. Blue with a bit of green produce appropriate variants of cyan. Similarly, blue combined with some red and hints of green give us suitable shades of purple. Due to the need of maintaining some difference in hueness between adjacent colors, it is not possible to make red, green, and yellow the main colors, because blue cannot be used to control their luminance and, thus the relevant space will shrink considerably. *note Is the contrast ratio about adjacent colors?:: This phenomenon is best illustrated by the following table that measures the relative luminance of shades of red, yellow, magenta against white: | | #ffffff | |---------+---------| | #990000 | 8.92 | | #995500 | 5.75 | | #990099 | 7.46 | We notice that equal values of red and blue light in ‘#990099’ (magenta shade) do not lead to a considerable change in luminance compared with ‘#990000’ (red variant). Whereas less amount of green light in ‘#995500’ leads to a major drop in luminance relative to white. It follows that using the green channel of light to calibrate the luminance of colors is more effective than trying to do the same with either red or blue (the latter is the least effective in that regard). When we need to work with several colors, it is always better to have sufficient manoeuvring space, especially since we cannot pick arbitrary colors but only those that satisfy the accessibility objectives of the themes. As for why we do not mostly use green, yellow, cyan for the dark theme, it is because those colors are far more luminant than their counterparts on the other side of the spectrum, so to ensure that they all have about the same contrast ratios we would have to alter their hueness considerably. In short, the effect would not be optimal as it would lead to exaggerations. Plus, it would make ‘modus-vivendi’ look completely different than ‘modus-operandi’, to the effect that the two could not be properly considered part of the same project.  File: modus-themes.info, Node: What is the best setup for legibility?, Next: Are these color schemes?, Prev: Why are colors mostly variants of blue magenta cyan?, Up: Frequently Asked Questions 8.4 What is the best setup for legibility? ========================================== The Modus themes can be conceptually simplified as combinations of color values that account for relative luminance and inner harmony. Those qualities do not guarantee that every end-user will have the same experience, due to differences between people, but also because of variances in hardware capabilities and configurations. For the purposes of this document, we may only provide suggestions pertaining to the latter case. ‘modus-operandi’ is best used outdoors or in a room that either gets direct sunlight or has plenty of light. Whereas ‘modus-vivendi’ works better when there is not a lot of sunshine or the room has a source of light that is preferably a faint and/or warm one. It is possible to use ‘modus-operandi’ at night and ‘modus-vivendi’ during the day, though that will depend on several variables, such as one’s overall perception of color, the paint on the walls and how that contributes to the impression of lightness in the room, the sense of space within the eye’s peripheral vision, hardware specifications, and environmental factors. In general, an additional source of light other than that of the monitor can help reduce eye strain: the eyes are more relaxed when they do not have to focus on one point to gather light. The monitor’s display settings must be accounted for. Gamma values, in particular, need to be calibrated to neither amplify nor distort the perception of black. Same principle for sharpness, brightness, and contrast as determined by the hardware, which all have an effect on how text is read on the screen. There are software level methods on offer, such as the XrandR utility for the X Window System (X.org), which can make gamma corrections for each of the three channels of light (red, green, blue). For example: xrandr --output LVDS1 --brightness 1.0 --gamma 0.76:0.75:0.68 Typography is another variable. Some font families are blurry at small point sizes. Others may have a regular weight that is lighter (thiner) than that of their peers which may, under certain circumstances, cause a halo effect around each glyph. The gist is that legibility cannot be fully solved at the theme level. The color combinations may have been optimized for accessibility, though the remaining contributing factors in each case need to be considered in full.  File: modus-themes.info, Node: Are these color schemes?, Next: Port the Modus themes to other platforms?, Prev: What is the best setup for legibility?, Up: Frequently Asked Questions 8.5 Are these color schemes? ============================ No, the Modus themes are not color schemes. A color scheme is a collection of colors. A good color scheme is a combination of colors with an inner logic or abstract structure. A theme is a set of patterns that are applied across different contexts. A good theme is one that does so with consistency, though not uniformity. In practical terms, a color scheme is what one uses when, for example, they replace the first sixteen escape sequences of a terminal emulator with color values of their preference. The terminal offers the option to choose, say, the exact value of what counts as “red”, but does not provide the means to control where that is mapped to and whether it should also have other qualities such as a bold weight for the underlying text or an added background color. In contradistinction, Emacs uses constructs known as “faces” which allow the user/developer to specify where a given color will be used and whether it should be accompanied by other typographic or stylistic attributes. By configuring the multitude of faces on offer we thus control both which colors are applied and how they appear in their context. When a package wants to render each instance of “foo” with the “bar” face, it is not requesting a specific color, which makes things considerably more flexible as we can treat “bar” in its own right without necessarily having to use some color value that we hardcoded somewhere. Which brings us to the distinction between consistency and uniformity where our goal is always the former: we want things to look similar across all interfaces, but we must never force a visual identity where that runs contrary to the functionality of the given interface. For instance, all links are underlined by default yet there are cases such as when viewing listings of emails in Gnus (and Mu4e, Notmuch) where (i) it is already understood that one must follow the indicator or headline to view its contents and (ii) underlining everything would make the interface virtually unusable. Again, one must exercise judgement in order to avoid discrimination, where “discrimination” refers to: • The treatment of substantially different magnitudes as if they were of the same class. • Or the treatment of the same class of magnitudes as if they were of a different class. (To treat similar things differently; to treat dissimilar things alike.) If, in other words, one is to enforce uniformity without accounting for the particular requirements of each case—the contextual demands for usability beyond matters of color—they are making a not-so-obvious error of treating different cases as if they were the same. The Modus themes prioritize “thematic consistency” over abstract harmony or regularity among their applicable colors. In concrete terms, we do not claim that, say, our yellows are the best complements for our blues because we generally avoid using complementary colors side-by-side, so it is wrong to optimize for a decontextualised blue+yellow combination. Not to imply that our colors do not work well together because they do, just to clarify that consistency of context is what themes must strive for, and that requires widening the scope of the design beyond the particularities of a color scheme. Long story short: color schemes and themes have different requirements. Please do not conflate the two.  File: modus-themes.info, Node: Port the Modus themes to other platforms?, Prev: Are these color schemes?, Up: Frequently Asked Questions 8.6 Port the Modus themes to other platforms? ============================================= There is no plan to port the themes to other platforms or text editors. I (Protesilaos) only use GNU Emacs and thus cannot maintain code that targets software I am either not familiar with or am not using on a daily basis. While it is possible to produce a simulacrum based on a given template, doing so would run contrary to how this project is maintained where details matter greatly. Each program has its own requirements so it won’t always be possible—or indeed desirable—to have 1:1 correspondence between what applies to Emacs and what should be done elsewhere. No port should ever strive to be a copy of the Emacs implementation, as no other program is an Emacs equivalent, but instead try to follow the spirit of the design. For example, some of the customization options accept a list as their value, or an alist, which may not be possible to reproduce on other platforms. *note Customization options::. In other words, if something must be done differently on a certain editor then that is acceptable so long as (i) the accessibility standards are not compromised and (ii) the overall character of the themes remains consistent. The former criterion should be crystal clear as it pertains to the scientific foundations of the themes: high legibility and taking care of the needs of users with red-green/blue-yellow color deficiency (deuteranopia and tritanopia) by avoiding red+green color coding paradigms and/or by providing yellow+blue variants for deuteranopia and red+cyan for tritanopia (*note Overview::). The latter criterion is the “je ne sais quoi” of the artistic aspect of the themes, which is partially fleshed out in this manual. *note Frequently Asked Questions::. With regard to the artistic aspect (where “art” qua skill may amount to an imprecise science), there is no hard-and-fast rule in effect as it requires one to exercize discretion and make decisions based on context-dependent information or constraints. As is true with most things in life, when in doubt, do not cling on to the letter of the law but try to understand its spirit. For a trivial example: the curly underline that Emacs draws for spelling errors is thinner than, e.g., what a graphical web browser has, so if I was to design for an editor than has a thicker curly underline I would make the applicable colors less intense to counterbalance the typographic intensity of the added thickness. With those granted, if anyone is willing to develop a port of the themes, they are welcome to contact me and I will do my best to help them in their efforts.

It is preferable that your feedback includes some screenshots, GIFs, or short videos, as well as further instructions to reproduce a given setup. Though this is not a requirement. Whatever you do, bear in mind the overarching objective of the Modus themes: to keep a contrast ratio that is greater or equal to 7:1 between background and foreground colors. If a compromise is ever necessary between aesthetics and accessibility, it shall always be made in the interest of the latter.  File: modus-themes.info, Node: Patches require copyright assignment to the FSF, Prev: Issues you can help with, Up: Contributing 9.3 Patches require copyright assignment to the FSF =================================================== Code contributions are most welcome. For any major edit (more than 15 lines, or so, in aggregate per person), you need to make a copyright assignment to the Free Software Foundation. This is necessary because the themes are part of the upstream Emacs distribution: the FSF must at all times be in a position to enforce the GNU General Public License. Copyright assignment is a simple process. Check the request form below (please adapt it accordingly). You must write an email to the address mentioned in the form and then wait for the FSF to send you a legal agreement. Sign the document and file it back to them. This could all happen via email and take about a week. You are encouraged to go through this process. You only need to do it once. It will allow you to make contributions to Emacs in general. Please email the following information to assign@gnu.org, and we will send you the assignment form for your past and future changes. Please use your full legal name (in ASCII characters) as the subject line of the message. REQUEST: SEND FORM FOR PAST AND FUTURE CHANGES [What is the name of the program or package you're contributing to?] GNU Emacs [Did you copy any files or text written by someone else in these changes? Even if that material is free software, we need to know about it.] Copied a few snippets from the same files I edited.

File: modus-themes.info, Node: GNU Free Documentation License, Next: Indices, Prev: Acknowledgements, Up: Top Appendix A GNU Free Documentation License ***************************************** Version 1.3, 3 November 2008 Copyright © 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 0. PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document “free” in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of “copyleft”, which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. 1. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The “Document”, below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as “you”. You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A “Modified Version” of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document’s overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The “Invariant Sections” are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The “Cover Texts” are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A “Transparent” copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not “Transparent” is called “Opaque”. Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The “Title Page” means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, “Title Page” means the text near the most prominent appearance of the work’s title, preceding the beginning of the body of the text. The “publisher” means any person or entity that distributes copies of the Document to the public. A section “Entitled XYZ” means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.) To “Preserve the Title” of such a section when you modify the Document means that it remains a section “Entitled XYZ” according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. 2. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. 3. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document’s license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice. H. Include an unaltered copy of this License. I. Preserve the section Entitled “History”, Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled “History” in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the “History” section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section Entitled “Endorsements”. Such a section may not be included in the Modified Version. N. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version’s license notice. These titles must be distinct from any other section titles. You may add a section Entitled “Endorsements”, provided it contains nothing but endorsements of your Modified Version by various parties—for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. 5. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled “History” in the various original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must delete all sections Entitled “Endorsements.” 6. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. 7. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an “aggregate” if the copyright resulting from the compilation is not used to limit the legal rights of the compilation’s users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 8. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 9. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. 10. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See . Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version” applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the Document. 11. RELICENSING “Massive Multiauthor Collaboration Site” (or “MMC Site”) means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A “Massive Multiauthor Collaboration” (or “MMC”) contained in the site means any set of copyrightable works thus published on the MMC site. “CC-BY-SA” means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization. “Incorporate” means to publish or republish a Document, in whole or in part, as part of another Document. An MMC is “eligible for relicensing” if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008. The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. ADDENDUM: How to use this License for your documents ==================================================== To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (C) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License''. If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the “with...Texts.” line with this: with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
