OrgRuby

https://secure.travis-ci.org/wallyqs/org-ruby.png?branch=master

An Org-mode parser written in Ruby.

Originally by Brian Dewey

Installation

gem install org-ruby

Usage

From Ruby:

require 'org-ruby'

# Renders HTML
Orgmode::Parser.new("* Hello world!").to_html
# => "<h1>Hello world!</h1>\n"

# Renders Textile
Orgmode::Parser.new("* Hello world!").to_textile
# => "h1. Hello world!\n" 

# Renders Markdown
Orgmode::Parser.new("* Hello world!").to_markdown
# => "# Hello world!\n" 

# Renders HTML with custom markup
Orgmode::Parser.new("* *Custom* /Markup/", { markup_file: "html.tags.yml" }).to_html
# => "<h1><strong>Custom</strong> <em>Markup</em></h1>\n"

# Renders Markdown with custom markup
Orgmode::Parser.new("* *Custom* /Markup/", { markup_file: "md.tags.yml"}).to_markdown
# => "# __Custom__ _Markup_\n"

The supported output exporters can be also called from the command line:

org-ruby --translate html         sample.org
org-ruby --translate textile      sample.org
org-ruby --translate markdown     sample.org
org-ruby --markup html.tags.yml   sample.org
org-ruby --markup md.tags.yml --translate markdown sample.org

Current status

Not all of the Org mode features are implemented yet. Currently, the development of the gem is mostly oriented towards giving support for exporting Org mode into other formats.

Brief list of features supported:

  • Converts Org mode files to HTML, Textile or Markdown.
  • Supports tables, block quotes, code blocks, and html blocks
  • Supports bold, italic, underline, strikethrough, and code inline formatting.
  • Supports hyperlinks
  • Supports lists
  • Supports footnotes
  • Supports .org views in Rails through Tilt.
  • Code syntax highlight of code blocks using Pygments.rb or Coderay when available

Custom Markup

Org-ruby supports custom markups for HTML and Markdown. The custom markup needs to be in the form of a YAML file with the following keys and values:

HTML Blocktags

---
:HtmlBlockTag:
  :paragraph: p
  :ordered_list: ol
  :unordered_list: ul
  :list_item: li
  :definition_list: dl
  :definition_term: dt
  :definition_descr: dd
  :table: table
  :table_row: tr
  :quote: blockquote
  :example: pre
  :src: pre
  :inline_example: pre
  :center: div
  :heading1: h1
  :heading2: h2
  :heading3: h3
  :heading4: h4
  :heading5: h5
  :heading6: h6
  :title: h1

For example, you only want to change the blockquote HTML tag to be translated, your YAML file would look like this:

---
:HtmlBlockTag:
  :quote: pre

This will change the HTML markup to be translated in the blockquote element.

HTML Emphasis:

---
:Tags:
  "*":
    :open: b
    :close: b
  "/": 
    :open: i
    :close: i 
  "_":  
    :open: span style=\"text-decoration:underline;\"
    :close: span
  "=":   
    :open: code
    :close: code
  "~":   
    :open: code
    :close:  code
  "+":
    :open: del
    :close: del

Let’s say that you prefer <strong> over <b> in the Bold emphasis element of Org-mode, your YAML file should look like this:

---
:Tags:
  "*":
    :open: strong
    :close: strong
  "/":
    :open: em
    :close: em

Markdown:

---
:MarkdownMap:
  "*": "**"
  "/": "*"
  "_": "*"
  "=": "`"
  "~": "`"
  "+": "~~"

Let’s say that you prefer underscores for Bold and Italics elements in Markdown, your YAML file should look like this:

---
:MarkdownMap:
  "*": "__"
  "/": "_"

Projects using it

  • Used at github/markup for rendering .org files
  • The Gollum project uses it too
  • Gitlab includes it for rendering Org files with syntax highlighting
  • Can be used with Jekyll for building a site: example here
