This is the content and its server for the extensions/apps documentation served
Documentation for apps and extensions are partly generated from API definitions
(for the reference material), and partly hand-written.
All documentation sources are checked into source control, just like any other
Chrome source code. The server consumes these sources and generates the
documentation web pages dynamically.
The goals of this system are:
* Docs are generated from API definitions; it isn't possible to add or modify
APIs without creating stub reference documentation at the same time.
* Docs are editable by anyone with Chrome commit access. This encourages
developers to do their part to keep doc up to date, and allows part-time
contributors to help too.
* Docs go live automatically and immediately, upon check-in. There's no separate
push process for docs.
* Docs are branched automatically with Chrome's source code; the docs for each
Chrome release are kept with the corresponding source code.
* Users can always find the current doc for any Chrome release channel (i.e.,
/trunk/extensions/, /beta/apps/, etc.). These URLs are updated automatically
with Chrome's release process.
Editing docs
1. Edit files.
- If you are not updating the static HTML for a docs page, you will most
likely not have to do anything. The docs server will automatically pick
up changes to the JSON or IDL schemas.
- Otherwise, they will be in chrome/common/extensions/docs/templates/.
See the "Overview of directories" section for more information.
Chances are you'll want to change a file in either "intros" (if changing
API documentation) or "articles" (if changing non-API documentation).
If adding files or APIs you'll also need to add something to "public".
- Files in templates directory use the Handlebar template language. It is
extremely simple, essentially: write HTML.
See third_party/handlebar/
- static/css/out/site.css is generated by compiling static/sass/*.scss
files. Don't change site.css directly. Instead, change the *.scss files
and run compass from this (docs/) directory:
compass compile .
See to install compass.
See for configuration
information (config.rb).
2. Run 'server2/'
3. Check your work at http://localhost:8000/(apps|extensions)/<doc_name>
4. Upload patch and offer reviewers a preview link at a URL with your patch
number and files, similar to:
5. Commit files as with any other Chrome change. The live server will update
within 5-10 minutes.
Overview of directories
* examples: The source for the sample extensions. Note that the sample apps are
checked into github at
* server2: The Python AppEngine server which serves all the content (living at Unless you're developing the server itself, you won't
need to worry about this (and if you are, see the README in there).
* static: The static content (images, CSS, JavaScript, etc).
* templates: These are the templates that server2 interprets and generates HTML
content with. This has four subdirectories:
- intros: The static content that appears before the API reference on API
- articles: The static content that appears on non-API pages.
- public: The top level templates for all pages.
- private: Helper templates used in rendering the docs.
