The `mermaid` shortcode generates diagrams and flowcharts from text, in a similar manner as Markdown using the [Mermaid](https://mermaidjs.github.io/) library.
|

||

|

{{% notice note %}}
|
||

This only works in modern browsers.

|
||
|
Due to limitations with [Mermaid](https://github.com/mermaid-js/mermaid/issues/1846), it is currently not possible to use Mermaid code fences in an initially collapsed `expand` shortcode. This is a know issue and [can't be fixed by this theme](https://github.com/McShelby/hugo-theme-relearn/issues/187).
|
||
|
{{% /notice %}}
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports Mermaid codefences (eg. GitHub) and so your markdown becomes more portable.
|
||
|
|
||
|
You are free to also call this shortcode from your own partials.
|
||
|
|
||
|
{{% notice note %}}
|
||
|
To use codefence syntax you have to turn off `guessSyntax` for the `markup.highlight` setting ([see the configuration section](#configuration)).

The generated graphs can be be panned by dragging them and zoomed by using the mousewheel. On mobile devices you can use finger gestures.

### Parameter
|
||
|
|
||
|
| Name | Default | Notes |
|
||
|
|:----------------------|:-----------------|:------------|
|
||
|
| **align** | `center` | Allowed values are `left`, `center` or `right`. |
|
||
|
| _**<content>**_ | _<empty>_ | Your Mermaid graph. |
|
||
|
|
||
|
## Configuration
|
||
|
|
||
|
Mermaid is configured with default settings. You can customize Mermaid's default settings for all of your files thru a JSON object in your `config.toml`, override these settings per page thru your pages frontmatter or override these setting per diagramm thru [diagram directives](https://mermaid-js.github.io/mermaid/#/directives?id=directives).
|
||
|
|
||
|
The JSON object of your `config.toml` / frontmatter is forwarded into Mermaid's `mermaid.initialize()` function.
|
||
|
|
||
|
See [Mermaid documentation](http://mermaid-js.github.io/mermaid/#/Setup?id=mermaidapi-configuration-defaults) for all allowed settings.
|
||
|
|
||
|
The `theme` setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in `config.toml`, frontmatter or diagram directives.
|
||
|
|
||
|
{{% notice note %}}
|
||
|
To use codefence syntax you have to turn off `guessSyntax` for the `markup.highlight` setting.
|
||
|
{{% /notice %}}
|
||
|
|
||
|
### Global Configuration File
|
||
|
|
||
|
````toml
|
||
|
[params]
|
||
|
mermaidInitialize = "{ \"theme\": \"dark\" }"
|
||
|
|
||
|
[markup]
|
||
|
[markup.highlight]
|
||
|
# if `guessSyntax = true`, there will be no unstyled code even if no language
|
||
|
# was given BUT Mermaid and Math codefences will not work anymore! So this is a
|
||
|
# mandatory setting for your site if you want to use Mermaid codefences
|
||
|
guessSyntax = false
|
||
|
````
|
||
|
