DoubleDoc 2.0

Write documentation with your code, to keep them in sync, ideal for public API docs.

This document was generated using DoubleDoc from doc/readme.md, and the source of this project is a great source for how to use DoubleDoc.

Documentation Format

Write documentation in markdown right in source code files by double commenting it:

class User < ActiveRecord::Base
  ## ```js
  ## {
  ##   "id":   1,
  ##   "name": "Mick Staugaard"
  ## }
  ## ```
  def as_json
    # this comment will not be included in the documentation
    # as it only has a single # character
    super(only: [:id, :name])
  end
end

class UsersController < ApplicationController
  ## ### Getting a User
  ## `GET /users/{id}.json`
  ##
  ## #### Format
  ## @import app/models/user.rb
  def show
    render json: User.find(params[:id])
  end
end

Then write a markdown document about User API:

## Users
Access users by using our REST API, blah blah blah...

@import app/controllers/users_controller.rb

And DoubleDoc will generate this markdown document:

## Users
Access users in by using our REST API, blah blah blah...

### Getting a User
`GET /users/{id}.json`

#### Format
```js
{
  "id":   1,
  "name": "Mick Staugaard"
}
```

Rake Task

Generate documentation by telling DoubleDoc what the input files are, and where the output should go. In the example, double_doc is picked to avoid conflicts with the doc rake task in rails.

require 'double_doc'

DoubleDoc::Task.new(
  :double_doc,
  sources:          'doc/source/*.md',
  md_destination:   'doc/generated',
  html_destination: 'site'
)

The available options are:

require 'double_doc'

DoubleDoc::Task.new(:double_doc, sources: 'doc/README.md', md_destination: '.')

Then run rake double_doc, which will generate a readme.md in the root of the project.

If a gh-pages branch exists, run rake doc:publish to generate html documentation and push it to your github pages.

Notes

• Tested on ruby 2.0+
• Does not work on jruby because of its dependency on redcarpet.

TODO

• Support for directory structures
• Documentation for the Guard
• Add support for extracting documentation from JavaScript files
