;;; Commentary:
|
|||
|
|
|
|||
|
|
;; Taking inspiration from prefix keys and prefix arguments, Transient
|
|||
|
|
;; implements a similar abstraction involving a prefix command, infix
|
|||
|
|
;; arguments and suffix commands. We could call this abstraction a
|
|||
|
|
;; "transient command", but because it always involves at least two
|
|||
|
|
;; commands (a prefix and a suffix) we prefer to call it just a
|
|||
|
|
;; "transient".
|
|||
|
|
|
|||
|
|
;; When the user calls a transient prefix command, then a transient
|
|||
|
|
;; (temporary) keymap is activated, which binds the transient's infix
|
|||
|
|
;; and suffix commands, and functions that control the transient state
|
|||
|
|
;; are added to `pre-command-hook' and `post-command-hook'. The
|
|||
|
|
;; available suffix and infix commands and their state are shown in
|
|||
|
|
;; the echo area until the transient is exited by invoking a suffix
|
|||
|
|
;; command.
|
|||
|
|
|
|||
|
|
;; Calling an infix command causes its value to be changed, possibly
|
|||
|
|
;; by reading a new value in the minibuffer.
|
|||
|
|
|
|||
|
|
;; Calling a suffix command usually causes the transient to be exited
|
|||
|
|
;; but suffix commands can also be configured to not exit the
|
|||
|
|
;; transient state.

While a transient is active the transient popup buffer is not the

current buffer, making it necessary to use dedicated commands to

act on that buffer itself. If this is non-nil, then the following

|

\\<transient-popup-navigation-map>\

\\<transient-button-map>\
|

- \\`<mouse-1>' and \\`<mouse-2>' invoke the clicked on suffix.

\\<transient-popup-navigation-map>\

All other bindings are in `transient-popup-navigation-map'.

|
|
|

By default \\`M-RET' is bound to `transient-push-button', instead of

\\`RET', because if a transient allows the invocation of non-suffixes

|
|
|
|||
|
|
The value of this option has the form (FUNCTION . ALIST),
|
|||
|
|
where FUNCTION is a function or a list of functions. Each such
|
|||
|
|
function should accept two arguments: a buffer to display and an
|
|||
|
|
alist of the same form as ALIST. See info node `(elisp)Choosing
|
|||
|
|
Window' for details.
|
|||
|
|
|
|||
|
|
The default is:
|
|||
|
|
|
|||
|
|
(display-buffer-in-side-window
|
|||
|
|
(side . bottom)
|
|||
|
|
(dedicated . t)
|
|||
|
|
(inhibit-same-window . t)
|
|||
|
|
(window-parameters (no-other-window . t)))
|
|||
|
|
|
|||
|
|
This displays the window at the bottom of the selected frame.
|
|||
|
|
Another useful FUNCTION is `display-buffer-below-selected', which
|
|||
|
|
is what `magit-popup' used by default. For more alternatives see
|
|||
|
|
info node `(elisp)Display Action Functions' and info node
|
|||
|
|
`(elisp)Buffer Display Action Alists'.
|
|||
|
|
|
|||
|
|
Note that the buffer that was current before the transient buffer
|
|||
|
|
is shown should remain the current buffer. Many suffix commands
|
|||
|
|
act on the thing at point, if appropriate, and if the transient
|
|||
|
|
buffer became the current buffer, then that would change what is
|
|||
|
|
at point. To that effect `inhibit-same-window' ensures that the
|
|||
|
|
selected window is not used to show the transient buffer.
|
|||
|
|
|
|||
|
|
It may be possible to display the window in another frame, but
|
|||
|
|
whether that works in practice depends on the window-manager.
|
|||
|
|
If the window manager selects the new window (Emacs frame),
|
|||
|
|
then that unfortunately changes which buffer is current.
|
|||
|
|
|
|||
|
|
If you change the value of this option, then you might also
|
|||
|
|
want to change the value of `transient-mode-line-format'."

argument supported by the constructor of that class. The

GROUPs add key bindings for infix and suffix commands and specify

one GROUP has to be specified. See info node `(transient)Binding

The BODY is optional. If it is omitted, then ARGLIST is also

ignored and the function definition becomes:

(interactive)
|
|||
|
|
(transient-setup \\='NAME))
|
|||
|
|
|

|
|
If BODY is specified, then it must begin with an `interactive'
|
|||
|
|
form that matches ARGLIST, and it must call `transient-setup'.
|
|||
|
|
It may however call that function only when some condition is
|

|
|
satisfied; that is one of the reason why you might want to use
|

|
|
an explicit BODY.
|

All transients have a (possibly nil) value, which is exported
|

|
|
when suffix commands are called, so that they can consume that
|
|||
|
|
value. For some transients it might be necessary to have a sort
|
|||
|
|
of secondary value, called a scope. Such a scope would usually
|
|||
|

be set in the commands `interactive' form and has to be passed

The key-value pairs are mandatory. All transient infix commands
|

are equal to each other (but not eq), so it is meaningless to
|

|
|
define an infix command without also setting at least `:class'
|

|

and one other keyword (which it is depends on the used class,
|
|||
|
|
usually `:argument' or `:variable').
|

|
|
|

Each key has to be a keyword symbol, either `:class' or a keyword

`transient-switch' class is used if the class is not specified

|
|||
|
|
|

|
|
`transient-infix-read' and `transient-infix-set' are generic
|
|||
|
|
functions. Different infix commands behave differently because
|
|||
|
|
the concrete methods are different for different infix command
|
|||

classes. In rare case the above command function might not be
|

suitable, even if you define your own infix command class. In

that case you have to use `transient-define-suffix' to define

the infix command and use t as the value of the `:transient'

|

"Return the object associated with the current suffix command.
|
|||
|
|
|
|||
|
|
Each suffix commands is associated with an object, which holds
|
|||
|
|
additional information about the suffix, such as its value (in
|
|||
|
|
the case of an infix command, which is a kind of suffix command).
|
|||
|
|
|
|||
|
|
This function is intended to be called by infix commands, whose
|
|||
|
|
command definition usually (at least when defined using
|
|||
|
|
`transient-define-infix') is this:
|
|||
|
|
|
|||
|
|
(lambda ()
|
|||
|
|
(interactive)
|
|||
|
|
(let ((obj (transient-suffix-object)))
|
|||
|
|
(transient-infix-set obj (transient-infix-read obj)))
|
|||
|
|
(transient--show))
|
|||
|
|
|
|||
|
|
\(User input is read outside of `interactive' to prevent the
|
|||
|
|
command from being added to `command-history'. See #23.)
|
|||
|
|
|
|||
|
|
Such commands need to be able to access their associated object
|
|||
|
|
to guide how `transient-infix-read' reads the new value and to
|
|||
|
|
store the read value. Other suffix commands (including non-infix
|
|||
|
|
commands) may also need the object to guide their behavior.
|
|||
|
|
|
|||
|
|
This function attempts to return the object associated with the
|
|||
|
|
current suffix command even if the suffix command was not invoked
|
|||
|
|
from a transient. (For some suffix command that is a valid thing
|
|||
|
|
to do, for others it is not.) In that case nil may be returned
|
|||
|
|
if the command was not defined using one of the macros intended
|
|||
|
|
to define such commands.
|
|||
|
|
|
|||
|
|
The optional argument COMMAND is intended for internal use. If
|
|||
|
|
you are contemplating using it in your own code, then you should
|
|||
|

probably use this instead:

`transient--with-emergency-exit' arranges for the transient to
