Docutils: Documentation Utilities Code

This is a test of the new "code" directive:

The example from Docutils TODO list:

.. code:: python

  print 'This is Python code.'
  for i in range(10):
      print i

Numbered lines:

.. code:: python
  :number-lines:

  # This is Python code,
  # that prints the integers from 0 to 9
  for i in range(10):
      print i

Another example:

.. code:: python
  :class: silly
  :name: my_function
  :number-lines: 7

  def my_function():
      """Test the lexer.
      """

      # and now for something completely different
      print 8/2

And now some CSS:

.. code:: css

  p.topic-title {
    font-weight: bold }

  pre.address {
    margin-bottom: 0 ;
    margin-top: 0 ;
    font: inherit }

as well as TeX:

.. code:: tex

  % hyperlinks:
  \ifthenelse{\isundefined{\hypersetup}}{
    \usepackage[linkcolor=blue,urlcolor=blue]{hyperref}
    \urlstyle{same} % normal text font (alternatives: tt, rm, sf)
  }{}

  \begin{document}

  The area of a circle is $A = \pi/4 d^2$

  \end{document}

You can also highlight a diff:
