Chapters1 Textile
Guides are written in Textile. There’s comprehensive documentation here and a cheatsheet for markup here.
2 Prologue
Each guide should start with motivational text at the top. That’s the little introduction in the blue area. The prologue should tell the readers what’s the guide about, and what will they learn. See for example the Routing Guide.
3 Titles
The title of every guide uses h2, guide sections use h3, subsections h4, etc.
Capitalize all words except for internal articles, prepositions, conjuctions, and forms of the verb to be:
h5. Middleware Stack is an Array h5. When are Objects Saved?
Use same typography as in regular text:
h6. The +:content_type+ Option
4 API Documentation Guidelines
The guides and the API should be coherent where appropriate. Please have a look at these particular sections of the API Documentation Guidelines:
Those guidelines apply also to guides.
5 HTML Generation
To generate all the guides just cd into the railties directory and execute
rake generate_guides
You’ll need the gems erubis, i18n, and RedCloth.
To process my_guide.textile and nothing else use the ONLY environment variable:
rake generate_guides ONLY=my_guide
Although by default guides that have not been modified are not processed, so ONLY is rarely needed in practice.
To force process of al the guides pass ALL=1.
It is also recommended that you work with WARNINGS=1, this detects duplicate IDs and warns about broken internal links.
6 HTML validation
Please do validate the generated HTML with
rake validate_guides
Particularly, titles get an ID generated from their content and this often leads to duplicates. Please set WARNINGS=1 when generating guides to detect them. The warning messages suggest a way to fix them.
