~~~~~~~~
|

|

Pygments is a syntax highlighting package written in Python.
|
||||
|
||||
It is a generic syntax highlighter suitable for use in code hosting, forums,
|
||||
wikis or other applications that need to prettify source code. Highlights
|
||||
are:
|
||||
|
||||
* a wide range of over 300 languages and other text formats is supported
|
||||
* special attention is paid to details, increasing quality by a fair amount
|
||||
* support for new languages and formats are added easily
|
||||
* a number of output formats, presently HTML, LaTeX, RTF, SVG, all image formats that PIL supports and ANSI sequences
|
||||
* it is usable as a command-line tool and as a library

README for Pygments
|
||||
===================
|
||||
|
||||
This is the source of Pygments. It is a generic syntax highlighter that
|
||||
supports over 300 languages and text formats, for use in code hosting, forums,
|
||||
wikis or other applications that need to prettify source code.
|
||||
|
||||
Installing
|
||||
----------
|
||||
|
||||
... works as usual, use ``python setup.py install``.
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
... can be found online at http://pygments.org/ or created by ::
|
||||
|
||||
cd doc
|
||||
make html
|
||||
|
||||
Development
|
||||
-----------
|
||||
|
||||
... takes place on `Bitbucket
|
||||
<https://bitbucket.org/birkenfeld/pygments-main>`_, where the Mercurial
|
||||
repository, tickets and pull requests can be viewed.
|
||||
|
||||
Continuous testing runs on drone.io:
|
||||
|
||||
.. image:: https://drone.io/bitbucket.org/birkenfeld/pygments-main/status.png
|
||||
:target: https://drone.io/bitbucket.org/birkenfeld/pygments-main
|
||||
|
||||
The authors
|
||||
-----------
|
||||
|
||||
Pygments is maintained by **Georg Brandl**, e-mail address *georg*\ *@*\ *python.org*.
|
||||
|
||||
Many lexers and fixes have been contributed by **Armin Ronacher**, the rest of
|
||||
the `Pocoo <http://dev.pocoo.org/>`_ team and **Tim Hatch**.

Todo
|
||||
====
|
||||
|
||||
- lexers that need work:
|
||||
* review perl lexer (numerous bugs, but so far no one had complaints ;)
|
||||
* readd property support for C# lexer? that is, find a regex that doesn't
|
||||
backtrack to death...
|
||||
* add support for function name highlighting to C++ lexer
|
||||
|
||||
- allow "overlay" token types to highlight specials: nth line, a word etc.
|
||||
|
||||
- pygmentize option presets, more sophisticated method to output styles?
