About
-----

Enhanced version of the original Python syntax highlighting script. Based on
``python.vim`` from Vim 6.1 distribution by Neil Schemenauer (nas at python dot
ca). Check also `python.vim page on vim.org
<http://www.vim.org/scripts/script.php?script_id=790>`_.

Features
--------

Changes from the original ``python.vim`` are:

- Added support for Python 3 syntax highlighting
- Added ``:Python2Syntax`` and ``:Python3Syntax`` commands which allow to
  switch between Python 2 and Python 3 syntaxes respectively without
  reloads/restarts
- Updated strings highlighting
- Enhanced special symbols highlighting inside strings
- Enhanced highlighting of numeric constants
- Added optional highlighting for %-formatting inside strings
- Added highlighting for magic comments: source code encoding and #!
  (executable) strings
- Added highlighting for new exceptions and builtins
- Added highlighting for doctests
- Added highlighting for new ``@decorator`` syntax introduced in Python 2.4a2
- Added highlighting for the following errors:

  - invalid symbols in source file
  - mixing spaces and tabs
  - invalid numeric constants
  - invalid %-formatting inside strings
  - invalid variable names
  - trailing spaces (triggered by the ``python_highlight_space_errors`` option)

Some of these features was later backported into the original ``python.vim``.

How to install
--------------

The easiest installation method is to place `syntax/python.vim
<https://github.com/hdima/python-syntax/blob/master/syntax/python.vim>`_ script
into your ``~/.vim/syntax/`` directory.

You can also use `Pathogen <https://github.com/tpope/vim-pathogen>`_ or `Vundle
<https://github.com/gmarik/vundle>`_ plugin managers in which case you can
install the whole `python.vim repository
<https://github.com/hdima/python-syntax>`_ into the corresponding plugins
directory.

Script options
--------------

There are two commands to enable or disable an option:

``:let OPTION_NAME = 1``
  Enable option
``:let OPTION_NAME = 0``
  Disable option

For example to enable all syntax highlighting features you can place the
following command in your ``~/.vimrc`` script::

  let python_highlight_all = 1
