Pygments
|
|
~~~~~~~~
|
|
|
|
Pygments is a syntax highlighting package written in Python.
|
|
|
|
It is a generic syntax highlighter for general use in all kinds of software
|
|
such as forum systems, wikis or other applications that need to prettify
|
|
source code. Highlights are:
|
|
|
|
* a wide range of common languages and markup 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
|
|
* ... and it highlights even Brainfuck!
|
|
|
|
The `Pygments tip`_ is installable with ``easy_install Pygments==dev``.
