Flex Diagrams is an extension that lets you create, and display, diagrams using three different JavaScript libraries: bpmn-js (for BPMN diagrams), DHTMLX Gantt (for Gantt charts), and Mermaid (for various kinds of diagrams, using the Mermaid JavaScript library). Each of these three gets its own namespace.

Any such diagram page will get, in addition to the standard "Edit" tab, an "Edit diagram" tab that allows for editing these diagrams in a graphical way. Thus, any diagram can be edited either as text, or graphically. (Although the Mermaid editor is unfortunately not a true graphical editor, but simply a text editor that includes a preview element.)

DownloadEdit

You can download the Flex Diagrams code, in .zip format, here: https://github.com/wikimedia/mediawiki-extensions-FlexDiagrams/archive/0.1.zip

You can also download the code directly via Git from the MediaWiki source code repository (see available tags). From a command line, call the following:

git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/FlexDiagrams.git

InstallationEdit

Once you have obtained a "FlexDiagrams" directory and placed it in your /extensions directory, add the following to LocalSettings.php:

wfLoadExtension( 'FlexDiagrams' );

Displaying diagramsEdit

Any diagram can be displayed on any page by using the #display_diagram function. This function takes in a single argument, a page name, and displays the diagram defined on that page. An example would be:

{{#display_diagram:BPMN:Approval process}}
