# Flowcharts Plugin for DokuWiki


Add flowcharts and diagrams to Dokuwiki with an intuitive syntax

The diagrams and flowcharts are generated with https://mermaidjs.github.io/.

**With the current version of the plugin it is crucial to remove the following lines from the Dokuwiki file conf/entities.conf** 


```
<->     ↔
->      →
<-      ←
---     —
--      –
```

Otherwise, Dokuwiki will render -> to → and then the diagrams are not rendered correctly since, e.g. → is the wrong syntax and we need -> etc. (For more information, see https://www.dokuwiki.org/entities and also https://github.com/splitbrain/dokuwiki/blob/master/conf/entities.conf.)

# Syntax

```
<flow>
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
</flow>
```

will be rendered to

![example diagram](examplediagram.png)

A nice feature is that each element of a diagram can be made clickable by using

```
<flow>
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;    
click A "SOMEPAGE"
</flow>
```
Clicking on `A` will take you to http://yoururl.com/SOMEPAGE. 

For further details on the syntax, see https://mermaidjs.github.io/. Diagrams can be built in realtime using https://mermaidjs.github.io/mermaid-live-editor/.

If you install this plugin manually, make sure it is installed in
lib/plugins/mermaidflowcharts/ - if the folder is called different it
will not work!

Please refer to http://www.dokuwiki.org/plugins for additional info
on how to install plugins in DokuWiki.
