grock

Grock converts your nicely commented code into a gorgeous documentation where comments and code live happily next to each other.

To see how it works, just have a look at the documentation rendered from this repository.

Install

Install globally using npm install --global grock and invoke anywhere using grock --glob 'your/*.files'.

Or use it as a (dev-)dependency in your project and use the package.json script section to run it, e.g. with "scripts": {"docs": "grock"} and using npm run docs (read more about this here).

Usage

Basically:

$ grock --glob 'lib/**/*.js' --out 'docs' --verbose

For more information about available options, see bin/grock or run grock --help:

$ grock --help
Usage: grock [options]

You can also use a configuration file named .groc.json to specify these options.
The defaults below show the values of the .groc.json file when possible.

Options:
  --help                    Show this message
  --version                 Show grock version
  --glob                    Set glob to match source files                                                  [default: ["*.md","bin/*","lib/**/*.coffee","lib/**/*.js","styles/**/*.coffee","styles/**/*.md","bin/*.js"]]
  --out                     Render documentation into here                                                  [default: "docs/"]

  --root                    The project's root directory                                                    [default: "."]
  --whitespace-after-token  Require whitespace after a comment token for a line to be considered a comment  [default: true]
  --repository-url          URL to link to source files                                                     [default: "https://github.com/killercup/grock"]
  --ext-scripts             An array of external scripts for appending to the template                      [default: []]
  --ext-styles              An array of external styles for appending to the template                       [default: []]
  --github                  Push generated docs to gh-pages branch                                          [default: false]
  --git-remote              Overwrite the remote for --github

Config File

You can specify all the command line options in a .groc.json file (that is compatible to groc). This will automatically be loaded. This way you just need to save that file in your project directory and can use grock without arguments from now on.

Auto Publish Documentation to Github Pages

Using the --github flag, grock will try to write the documentation not to an output directory, but to the gh-pages branch of your git repository. If it succeeds, it will immediately push the new changes to the origin remote (can be specified by --git-remote.

Assuming you have specified all other options in ./.groc.json, you can then run:

$ grock --github

Inspiration

Literate programming (the programming methodology coined by Donald Knuth)
Jeremy Ashkenas' docco
The groc project -- this implementation is heavily based on this, but uses node.js streams
Gulp.js, a build system that uses streams to transform files

What makes grock different?

In contrast to other node-based documentation generators like docco, groc, and docker, grock has the following advantages:

It doesn't need pygments.
Therefore it doesn't need python.
Therefore it's faster than those other tools that need pygments.
It renders a file tree and also a headline tree for each document.
The default style (based on solarized) is responsive and looks actually quite good on a phone.
It doesn't crash on malformed doc tags.
It's based on streams. I've heard all the cool kids are using streams now.

Based on

vinyl-fs for abstracting files
Solarized
marked
highlight.js

Oh, and all the heavy lifting (splitting code and comments, parsing doc tags) is actually code from groc!

Roadmap

Contributing

Just fork the repo, implement some awesome feature or fix a bug and send a pull request.

Code Style and Guideline

Document your code.
Write code in CoffeeScript when possible and make sure coffeelint doesn't throw any warning or errors.
Make use of streams and promises. Those are good techniques.
Split the code into as many independent, loosely coupled modules as possible and try to reuse existing ones.
Write tests for those small modules.
On the other hand, try to minimize (NPM) dependencies. Since this is a CLI tool, the startup time gets worse with every require.
Run npm test before committing. (Currently, this runs coffeelint and mocha).

Contributing to Styles

When adding a new style or editing an existing one, make sure you follow the guidelines in styles/Readme.md (e.g. adding an index file exporting copy, compile and template functions).
