RbST

A Ruby gem for processing reStructuredText via Python's Docutils.

Installation

Python 2.3+ (or 3.3+) is required.

RbST is available on RubyGems:

gem install RbST

To install with Bundler, add the following to your Gemfile:

gem 'RbST'

Then run bundle install

Usage

require 'rbst'
@latex = RbST.new('*hello*').to_latex

This takes the reStructuredText formatted string and converts it to LaTeX.

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

# One file path as a single-element array.
RbST.new(['/path/to/file.rst']).to_html

# Multiple file paths as an array.
RbST.new(['/path/to/file1.rst', '/path/to/file2.rst']).to_html

You can also use the convert class method to output HTML:

puts RbST.convert('*hello*')
#=> "<div class=\"document\">\n<p><em>hello</em></p>\n</div>\n"

Arguments can be passed to #to_html, #to_latex, new or convert, accepting symbols or strings for options without arguments and hashes of strings or symbols for options with arguments.

puts RbST.new('.. a comment').to_html('strip-comments')
# => '<div class="document">\n</div>'

Options passed as string use hyphens while symbols use underscores. For instance, the above could also be written as:

puts RbST.new('.. a comment').to_html(:strip_comments)
# => '<div class="document">\n</div>'

Document parts can also be specified with the :parts option.

puts RbST.new('hello world').to_html(:part => :fragment)
# => '<p>hello world</p>'

By default, RbST uses the html_body part for HTML and the whole part for LaTeX.

Available options can be viewed using the RbST.html_options and RbST.latex_options class methods.

You might run into a situation where you want to specify a custom script for processing one or both of the output formats. If so, just specify the full path to the custom script for the format by passing a hash to the RbST.executables= method:

RbST.executables = {:html => '/some/other/path/2html.py'}

# uses custom executable for outputting html
RbST.new('*hello*').to_html

# uses default executable for latex since a custom one wasn't specified
RbST.new('*hello*').to_latex

Similarly, if you want to explicitly specify which python executable to use, set the path with the RbST.python_path= method:

RbST.python_path = '/usr/bin/env python3'
RbST.new('*hello*').to_latex

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.
