If you want to extend Pygments without hacking the sources, but want to
use the lexer/formatter/style/filter lookup functions (`lexers.get_lexer_by_name`
et al.), you can use `setuptools`_ entrypoints to add new lexers, formatters
or styles as if they were in the Pygments core.
.. _setuptools: http://peak.telecommunity.com/DevCenter/setuptools
That means you can use your highlighter modules with the `pygmentize` script,
which relies on the mentioned functions.
Entrypoints
===========
Here is a list of setuptools entrypoints that Pygments understands:
`pygments.lexers`
This entrypoint is used for adding new lexers to the Pygments core.
The name of the entrypoint values doesn't really matter, Pygments extracts
required metadata from the class definition:
.. sourcecode:: ini
[pygments.lexers]
yourlexer = yourmodule:YourLexer
Note that you have to define ``name``, ``aliases`` and ``filename``
attributes so that you can use the highlighter from the command line:
.. sourcecode:: python
class YourLexer(...):
name = 'Name Of Your Lexer'
aliases = ['alias']
filenames = ['*.ext']
`pygments.formatters`
You can use this entrypoint to add new formatters to Pygments. The
name of an entrypoint item is the name of the formatter. If you
prefix the name with a slash it's used as a filename pattern:
.. sourcecode:: ini
[pygments.formatters]
yourformatter = yourmodule:YourFormatter
/.ext = yourmodule:YourFormatter
`pygments.styles`
To add a new style you can use this entrypoint. The name of the entrypoint
is the name of the style:
.. sourcecode:: ini
[pygments.styles]
yourstyle = yourmodule:YourStyle
`pygments.filters`
Use this entrypoint to register a new filter. The name of the
entrypoint is the name of the filter:
.. sourcecode:: ini
[pygments.filters]
yourfilter = yourmodule:YourFilter
How To Use Entrypoints
======================
This documentation doesn't explain how to use those entrypoints because this is
covered in the `setuptools documentation`_. That page should cover everything
you need to write a plugin.

Extending The Core
==================
If you have written a Pygments plugin that is open source, please inform us
about that. There is a high chance that we'll add it to the Pygments
distribution.
