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.
First, make sure to install Pandoc.
Next, install PandocRuby from RubyGems.
gem install pandoc-ruby
require 'pandoc-ruby'
@converter = PandocRuby.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 PandocRuby.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.
PandocRuby.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:
PandocRuby.new("# Some title").to_html(:no_wrap)
=> "<div id=\"some-title\"><h1>Some title</h1></div>"
# or
PandocRuby.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:
PandocRuby.html("<h1>hello</h1>").to_latex
=> "\\section{hello}"
PandocRuby assumes the pandoc executable is in the path. If you'd like to set
a custom executable path, you can do so
with PandocRuby.pandoc_path = '/path/to/pandoc'
Pandoc can also be set to take a file path as the first argument. For security reasons, this is disabled by default, but it can be enabled and used as follows
PandocRuby.allow_file_paths = true
PandocRuby.html('/some/file.html').to_markdown
Available format readers and writers are available in the PandocRuby::READERS
and PandocRuby::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 inspired by Albino. For a slightly different approach to using Pandoc with Ruby, see Pandoku.
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.
PandocRuby.new("# Some title", :standalone).to_rtf
- Ruby 1.9.3 or higher is required.
- This has only been tested on *nix systems.
- PDF conversion may require additional dependencies and has not been tested.
- 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.
