Ruby on Rails Guides Guidelines
This guide documents guidelines for writing Ruby on Rails Guides. This guide follows itself in a graceful loop, serving itself as an example.
Each guide should start with motivational text at the top (that’s the little introduction in the blue area). The prologue should tell the reader what the guide is about, and what they will learn. See for example the Routing Guide.
The title of every guide uses ; guide sections use ; subsections ; etc.
Capitalize all words except for internal articles, prepositions, conjunctions, and forms of the verb to be:
Middleware Stack is an Array
h5. When are Objects Saved?
Use the same typography as in regular text:
The :content_type Option
API Documentation Guidelines
The guides and the API should be coherent and consistent where appropriate. Please have a look at these particular sections of the API Documentation Guidelines:
Those guidelines apply also to guides.
To generate all the guides, just into the directory and execute:
bundle exec rake generate_guides
(You may need to run first to install the required gems.)
To process and nothing else use the environment variable:
bundle exec rake generate_guides ONLY=my_guide
By default, guides that have not been modified are not processed, so is rarely needed in practice.
To force processing all the guides, pass .
It is also recommended that you work with . This detects duplicate IDs and warns about broken internal links.
If you want to generate guides in a language other than English, you can keep them in a separate directory under (eg. source/es) and use the environment variable:
bundle exec rake generate_guides GUIDES_LANGUAGE=es
Please validate the generated HTML with:
bundle exec rake validate_guides
Particularly, titles get an ID generated from their content and this often leads to duplicates. Please set when generating guides to detect them. The warning messages suggest a solution.
To generate guides for the Kindle, you need to provide as an environment variable:
KINDLE=1 bundle exec rake generate_guides
