Usage

Put a widget="mermaid" attribute in relevant field tags in the view declaration:

<field name="flowchart" widget="mermaid"/>

Optionally, use an options attribute to pass a JSON object with mermaid configuration:

<field name="flowchart"
       widget="mermaid"
       options='{"theme": "forest", "gantt": {"fontSize": 14}}'/>

The syntax for creating diagrams is described in mermaid’s documentation.

As an example, this text:

graph LR
    10.0 --> 11.0
    11.0 --> 12.0
    12.0 -.-> 13.0

Produces this flowchart:

Demonstration

In demo mode, the addon adds a flowchart field to users so you can try it. This shows up in Runbot instances.

Upgrading Mermaid

This information is only relevant for the development of this addon, not for users.

This addon uses a slightly tweaked build of Mermaid that works in older browsers. To reproduce it, take the following steps:

• Clone https://github.com/knsv/mermaid/

• Checkout the version you want to upgrade to (e.g. git checkout 8.4.0)

• In webpack.config.base.js, in const jsRule = ..., remove the include key (so all dependencies are transpiled)

• In babel.config.js, in targets, add some browsers besides node: 'current'. I arbitrarily went with this:

  targets: {
    node: 'current',
    ie: '11',
    edge: '20',
    firefox: '35',
    chrome: '45',
    safari: '9',
  }

• Run yarn install

• Run yarn build

• The completed file is now in dist/mermaid.js. Try running grep 'let ' dist/mermaid.js to make sure everything was transpiled. The only output should be from comments.

• Copy dist/mermaid.js to web_widget_mermaid/static/lib/mermaid/mermaid.js.

• Bump the version number in __manifest__.py to match the Mermaid version.
