RubyPandoc

RubyPandoc is a wrapper for Pandoc, a Haskell library with command line tools for converting one markup format to another.

Pandoc can convert documents in markdown, reStructuredText, textile, HTML, DocBook, LaTeX, or MediaWiki markup to a variety of formats, including markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, HTML slide shows, EPUB, and Microsoft Word docx.

This documentation is for version 2 and higher. For version 1 documentation see here.

Installation

First, make sure to install Pandoc.

Next, add RubyPandoc to your Gemfile

gem 'ruby-pandoc'

or install RubyPandoc from RubyGems.

gem install ruby-pandoc

Usage

require 'ruby-pandoc'
@converter = RubyPandoc.new('# Markdown Title', :from => :markdown, :to => :rst)
puts @converter.convert

This takes the Markdown formatted file and converts it to reStructuredText.

You can also use the #convert class method:

puts RubyPandoc.convert('# Markdown Title', :from => :markdown, :to => :html)

Other arguments are simply converted into command line options, accepting symbols or strings for options without arguments and hashes of strings or symbols for options with arguments.

RubyPandoc.convert('# Markdown Title', :s, {:f => :markdown, :to => :rst}, 'no-wrap', :table_of_contents)

is equivalent to

echo "# Markdown Title" | pandoc -s -f markdown --to=rst --no-wrap --table-of-contents

Also provided are #to_[writer] instance methods for each of the writers, and these can also accept options:

RubyPandoc.new("# Some title").to_html(:no_wrap)
# => "<div id=\"some-title\"><h1>Some title</h1></div>"
# or
RubyPandoc.new("# Some title").to_rst
# => "Some title\n=========="

Similarly, there are class methods for each of the readers, so readers and writers can be specified like this:

RubyPandoc.html("<h1>hello</h1>").to_latex
# => "\\section{hello}"

RubyPandoc assumes the pandoc executable is via your environment's $PATH variable. If you'd like to set an explicit path to the pandoc executable, you can do so with RubyPandoc.pandoc_path = '/path/to/pandoc'

RubyPandoc can also take an array of one or more file paths as the first argument. The files will be concatenated together with a blank line between each and used as input.

# One file path as a single-element array.
RubyPandoc.html(['/path/to/file1.html']).to_markdown
# Multiple file paths as an array.
RubyPandoc.html(['/path/to/file1.html', '/path/to/file2.html']).to_markdown

Available format readers and writers are available in the RubyPandoc::READERS and RubyPandoc::WRITERS constants.

For more information on Pandoc, see the Pandoc documentation or run man pandoc (also available here).

If you'd prefer a pure-Ruby extended markdown interpreter that can output a few different formats, take a look at Maruku. If you want to use the full reStructuredText syntax from within Ruby, check out RbST, a docutils wrapper.

This gem was forked from pandoc-ruby. For a slightly different approach to using Pandoc with Ruby, see Pandoku.

Additional Notes

If you are trying to generate a standalone file with full file headers rather than just a marked up fragment, remember to pass the :standalone option so the correct header and footer are added.

RubyPandoc.new("# Some title", :standalone).to_rtf

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
