Merrrmaid

Merrrmaid be a library help'n ye t' generate diagram an' flowcharts from text, 'n a similar manner as Marrrkdown.

Usage

Just insert yer Merrrmaid code 'n th' mermaid shorrrtcode like this:

{{< mermaid [ align=("left"|"right"|"center"|"justify") ] >}}
classDiagram
    Person *-- Dog
{{< /mermaid >}}

Ye can set an optional align attribute which defaults t' "center".

If ye don’t need alignment ye can use th' alternative rules us'n code fences if ye have turned off guessSyntax fer th' marrrkup.highlight sett'n (see below):

```mermaid
classDiagram
    Person *-- Dog
```

Th' generated graphs can be be panned by dragg'n them an' zoomed by us'n th' mousewheel. On mobile devices ye can use finger gestures.

Examples

Flowchart

graph LR; A[Hard edge] -->|Link text| B(Round edge) B --> C{Decision} C -->|One| D[Result one] C -->|Two| E[Result two]
Show marrrkup 
{{< mermaid align="left" >}}
graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{<strong>Decision</strong>}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
{{< /mermaid >}}

Configurat'n

Merrrmaid be configured wit' default sett'ns. Ye can cust'mize Mermaid’s default sett'ns fer all o' yer files thru a JSON object 'n yer config.toml or override these sett'ns sidewise thru yer planks frontmatter.

This JSON object be forwarded into Mermaid’s mermaid.initialize() funct'n.

See Merrrmaid documentat'n fer all allowed sett'ns.

Also, if ye want t' use mermaid codefences, ye have t' turn off guessSyntax fer th' marrrkup.highlight sett'n.

Example

[params]
  mermaidInitialize = "{ \"theme\": \"dark\" }"

[markup]
  [markup.highlight]
    guessSyntax = false     # if set t' true, avoid unstyled code if no language was given but mermaid code fences will not work anymore

or planks frontmatter
