Sphinx-execute-code is an extension for Sphinx that allows a document author to insert arbitrary python code samples in code blocks, or run python code from python files on the filesystem.

This was written as an alternative to other code execution functions which relied on doctest formats, and attempts to be more flexible, similar to literal-block and code-block statements.

Options right now (as of version 0.2) are:

linenos

If specified, will show line numbers

output_language

Customizes pygments lexxer for specified language (Eg, Javascript, bash)

hide_code

If specified, will hide the code block and only show results

hide_headers

If specified, hides the 'Code' and 'Results' caption headers around the literal blocks

filename

If specified, will load code from a file (relative to sphinx doc root) and ignore content.

Running 'execute_code' as a directive allows the administrator to embed exact python code as if it was pasted in a normal code-block.

Executing python code and showing the result output:

.. execute_code::
    :linenos:

    print 'python highlight code'

    class Foo(object):
        def __init__(self):
            self.bar = 'baz'
        def out(self):
            print self.bar

    f = Foo()
    f.out()

Customizing the output syntax can be helpful to make it easy to document any other pygments lexxer - eg ini, javascript

We can customize the output language parser (for JSON/Javascript):

.. execute_code::
    :output_language: javascript

    print "'{foo-bar-baz}'"

You may want to hide the example code that is executing (avoiding highlighting/etc) and display the results only.

We can also hide the code input, showing only the executed code results:

.. execute_code::
    :hide_code:

    print 'This should not print the example code'

Suppressing the 'Headers' outputs for Code and Results header:

.. execute_code::
   :hide_headers:

   foo = 32
   print 'This will hide the Code and Results text - and foo is %d' % foo

execute_code also allows you to import a python file and execute it within a document.

Running a Python file from filename from the .py example:

.. execute_code::
   :filename: tests/example_class.py

This function also supports the argument 'hide_filename':

.. execute_code::
   :filename: tests/example_class.py
   :hide_filename:
