git clone https://git.savannah.gnu.org/git/emacs/org-mode.gitOrg-mode (also: Org mode; ) is a document editing, formatting, and organizing mode, designed for notes, planning, and authoring within the free software text editor Emacs. The name is used to encompass plain text files ("org files") that include simple marks to indicate levels of a hierarchy (such as the outline of an essay, a topic list with subtopics, nested computer code, etc.), and an editor with functions that can read the markup and manipulate hierarchy elements (expand/hide elements, move blocks of elements, check off to-do list items, etc.). Org-mode was created by Carsten Dominik in 2003, originally to organize his own life and work, and since the first release numerous other users and developers have contributed to this free software package.

* Motivation
The dominant simple plain-text markup languages for the web are
Textile and Markdown. A factor for the popularity of those markup
formats is the widespread availability of simple, free packages for
converting the formats to HTML. For example, the world of
Ruby-powered websites has settled on RedCloth for converting Textile
to HTML.
The default way to convert org-mode files to HTML is the powerful
publishing functionality provided by =emacs=. However, =emacs= does
not easiliy integrate into many existing website frameworks.
=Org-ruby= tries to make it easier to use org-mode files in both
dyanmic and static website generation tools written in
Ruby. =Org-ruby= is a simple Ruby gem to convert org-mode files to
HTML.
* Using Org-ruby
=Org-ruby= follows the same model as other Ruby markup
libraries. You install the gem:
#+BEGIN_EXAMPLE
sudo gem install org-ruby
#+END_EXAMPLE
Then, to convert an org-file to HTML in your Ruby code:
#+BEGIN_EXAMPLE
require 'rubygems'
require 'org-ruby'
data = IO.read(filename)
puts Orgmode::Parser.new(data).to_html
#+END_EXAMPLE
* Walkthrough: Using org-ruby with Webby
Here is an example of how to integrate =org-ruby= into Webby, a
static website generation tool written in Ruby.
Webby follows a similar pattern to other static site generation
tools (like nanoc, Jekyll, and webgen):
- You author website content in text with simple markup
- Each page is fed through one or more /filters/ to produce HTML
- The HTML is mixed in with layouts to produce the final pages
For a Webby site, a the source for a page may look like this:
#+BEGIN_EXAMPLE
---
title: Special Directories
created_at: 2009-12-17
status: Complete
filter:
- erb
- maruku
tags:
- powershell
---
<%= @page.title %>
==================
Special Directories are a set of directories, each of which has a
function that will navigate you to the appropriate directory using
the push-location cmdlet. For example, the function `home` might
navigate to `c:\users\bdewey.`
Install
-------
Copy the module to somewhere in `ENV:PSModulePath`. Then,
InstallModule SpecialDirectories
#+END_EXAMPLE
In the above example, the text is written in Markdown. At the top of
the file, metadata informs Webby to pass the text through two
/filters/ to produce HTML. The first filter, =erb=, handles embedded
Ruby. In this case, it will replace ~<%= @page.title %>~ with the
page title (=Special Directories=). The second filter uses Maruku to
translate Markdown into HTML.
You can use the exact same pattern to include org-mode files in a
Webby site. For this walkthrough, I assume you already have Webby
installed, and that you've already created a site.
1. Make sure you have =org-ruby= installed: =sudo gem install
org-ruby=.
2. You need to register a new Webby filter to handle org-mode
content. Webby makes this easy. In the =lib/= folder of your
site, create a file =orgmode.rb=:
#+BEGIN_EXAMPLE
require 'org-ruby'
Webby::Filters.register :org do |input|
Orgmode::Parser.new(input).to_html
end
#+END_EXAMPLE
This code creates a new filter, =org=, that will use the
=org-ruby= parser to translate org-mode input into HTML.
3. Create your content. For example:
#+BEGIN_EXAMPLE
---
title: Orgmode Parser
created_at: 2009-12-21
status: Under development
filter:
- erb
- org
tags:
- orgmode
- ruby
---
<%= @page.title %>
Status: <%= @page.status %>
* Description
Helpful Ruby routines for parsing orgmode files. The most
significant thing this library does today is convert orgmode files
to textile. Currently, you cannot do much to customize the
conversion. The supplied textile conversion is optimized for
extracting "content" from the orgfile as opposed to "metadata."
* History
** 2009-12-29: Version 0.4
- The first thing output in HTML gets the class "title"
- HTML output is now indented
- Proper support for multi-paragraph list items.
See? This paragraph is part of the last bullet.
- Fixed bugs:
- "rake spec" wouldn't work on Linux. Needed "require 'rubygems'".
#+END_EXAMPLE
This file will go through the =erb= and =org= filters; as defined
in the previous step, the =org= filter will use =org-ruby= to
generate HTML.
That's all there is to it!
