GitHub Markup
We use this library on GitHub when rendering your README or any other rich text file.
Markups
The following markups are supported. The dependencies listed are required if you wish to run the library.
- .markdown, .mdown, .md --
gem install redcarpet
(https://github.com/vmg/redcarpet) - .textile --
gem install RedCloth
- .rdoc --
gem install rdoc -v 3.6.1
- .org --
gem install org-ruby
- .creole --
gem install creole
- .mediawiki --
gem install wikicloth
- .rst --
easy_install docutils
- .asciidoc --
brew install asciidoc
- .pod --
Pod::Simple::HTML
comes with Perl >= 5.10. Lower versions should install Pod::Simple from CPAN.
Contributing
Want to contribute? Great! There are two ways to add markups.
Commands
If your markup is in a language other than Ruby, drop a translator script in lib/github/commands
which accepts input on STDIN and returns HTML on STDOUT. See rest2html for an example.
Once your script is in place, edit lib/github/markups.rb
and tell GitHub Markup about it. Again we look to rest2html for guidance:
command(:rest2html, /re?st(.txt)?/)
Here we're telling GitHub Markup of the existence of a rest2html
command which should be used for any file ending in rest
, rst
, rest.txt
or rst.txt
. Any regular expression will do.
Finally add your tests. Create a README.extension
in test/markups
along with a README.extension.html
. As you may imagine, the README.extension
should be your known input and the README.extension.html
should be the desired output.
Now run the tests: rake
If nothing complains, congratulations!
Classes
If your markup can be translated using a Ruby library, that's great. Check out lib/github/markups.rb
for some examples. Let's look at Markdown:
markup(:markdown, /md|mkdn?|markdown/) do |content|
Markdown.new(content).to_html
end
We give the markup
method three bits of information: the name of the file to require
, a regular expression for extensions to match, and a block to run with unformatted markup which should return HTML.
If you need to monkeypatch a RubyGem or something, check out the included RDoc example.
Tests should be added in the same manner as described under the Commands
section.
Installation
gem install github-markup
Usage
require 'github/markup'
GitHub::Markup.render('README.markdown', "* One\n* Two")
Or, more realistically:
require 'github/markup'
GitHub::Markup.render(file, File.read(file))
Testing
To run the tests:
$ rake
To add tests see the Commands
section earlier in this README.
