## githubify.rb automatically adds links to pull requests, issues, and
## commits using pattern matches
## Example (URL is the repository to link to):
## {% githubify https://github.com/bitcoin/bitcoin %}
## ...content...
## {% endgithubify %}
module Jekyll
require 'yaml'
class GitHubifyBlock < Liquid::Block
def initialize(tag_name, text, tokens)
super
@repository_url = text.strip()
end
def render(context)
output = super
## Convert #1234 into URL for the pull request
## If #1234 links to an issue, GitHub automatically redirects
#
## Require at least two digits to reduce false positive matches
output.gsub!(/#([0-9][0-9][0-9]*)/){ |s|
'' + s + ''
}
## Convert `123abcd` into URL for the commit
#
## Only operate on 7 to 10 chars to reduce false positive matches
output.gsub!(/`([0-9abcdef]{7,10})`/){ |s|
'' + s + ''
}
output
end
end
end
## Code to run if plugin is disabled
module Jekyll
require 'yaml'
class GitHubifyBlockDisabled < Liquid::Block
def initialize(tag_name, text, tokens)
super
end
def render(context)
output = super
output
end
end
end
#Do nothing if plugin is disabled
plugin_name = "githubify"
if !ENV['ENABLED_PLUGINS'].nil? and ENV['ENABLED_PLUGINS'].index(plugin_name).nil?
print plugin_name + ' disabled' + "\n"
Liquid::Template.register_tag(plugin_name, Jekyll::GitHubifyBlockDisabled)
else
Liquid::Template.register_tag(plugin_name, Jekyll::GitHubifyBlock)
end
