rdocs-light

Embeddable RDocumentation widget

How does it work?

Html elements with the data-mini-rdoc attribute will show a tooltip with information when hovered over. The value of the attribute should be of the form package::topic or just package. The version of the package can also be defined with the optional data-mini-rdoc-version attribute.

If the version attribute is not provided:

• For a package the documentation for the latest version of that package will be shown.
• For a topic the documentation for the topic in the latest version of the package (which contains the topic) will be shown.

How to use?

• Load rdocs-light.min.js in your webpage.
• Call rdl.initRDocsLight(options); on page load

Auto Link to RDocumentation

• Tags with the data-mini-rdoc attribute can be automatically changed to link to the documentation.
• Can also be used standalone (without initiating RDocsLight)
• Call rdl.autoLink();

Building

• After you downloaded this repository, run npm install for all the necessary dependencies.
• Create a .env file in which you define all environment variables. See .env.example for all variables that need to be defined. For example, if you also run the RDocumentation-app local, you will have to set API_BASE_URL to http://localhost:1337.
• Afterwards you can use npm run dev to build RDocs Light and node web.js to serve random examples with local build on http://localhost:3003/.
