IMPORTANT: Your vim must have Python 2.5, at least. Enter ":python import sys; print sys.version" to see which version you have.  The newest version of Vim, 7.3, comes bundled with Python 2.7 support.

pyflakes-vim highlights common Python errors like misspelling a variable name on the fly. It also warns about unused imports, redefined functions, etc.

This plugin is fast enough that it registers itself with vim hooks for leaving insert mode and saving a buffer, so that the warnings are always up to date. See pyflakes.vim if you want to change this behavior.

NOTES:
* an improved pyflakes module is INCLUDED with this plugin, so you don't need to install it separately
* quickfix entries are created for each error, so you can use commands like :cc to jump to errors.
* this plugin uses the SpellBad highlight to show errors. if you'd like to change the color or style of this highlight, you can do something like this in your .vimrc:

      if has("gui_running")
          highlight SpellBad term=underline gui=undercurl guisp=Orange
      endif

KNOWN ISSUES

- The highlighting for syntax errors is often way off, and results in no other errors being detected.
- In Python 2.5, typing a with statement before you have from __future__ import with results in a vim error
 
install details
1. Make sure your vimrc has "filetype plugin indent on" so that pyflake-vim's ftplugin files are loaded automatically when you open a Python buffer.
2. Drop extracted files in ~/.vim/ftplugin/python.
3. That's it!

See the README for more info.

Apparently CursorMoved can get called early, before RunPyflakes has run.
If this happens, just return.

Thanks EnTeQuAk.
pyflakes-vim.zip 1.55 2009-09-17 7.0 @kevinwatters http://github.com/kevinw/pyflakes-vim/commit/083bc2e65649a9cf10a7c1bcd22151a4083ddeb7

Highlight the whole line for SyntaxErrors.
pyflakes-vim.zip 1.5 2009-07-08 7.0 @kevinwatters http://github.com/kevinw/pyflakes-vim/commit/b8f2f366b1322a5ffefede30ddb3339102d2f28c

Ignore stderr during ast.parse, since it will otherwise show as VIM error
messages. Thanks Denis Bilenko.

Eventually we should parse some of the warnings. For example:

  foo.py:33: Warning: 'as' will become a reserved keyword in Python 2.6

This could become a visible warning.
pyflakes-vim.zip 1.4 2009-05-06 7.0 @kevinwatters http://github.com/kevinw/pyflakes-vim/commit/6ec1fbbce32876e315b370409ca55c97d232d125

Restrict dd, dw, etc mappings to the local Python buffer.
pyflakes-vim.zip 1.3 2009-04-21 7.0 @kevinwatters Some fixes based on suggestions from Brandon Low:

- changed highlight call from hard coding a curly underline to linking with the "SpellBad" style. This is more friendly vim on terminals. If you'd like the old brighter orange undercurl from previous versions, add the following to your .vimrc:

    if has("gui_running")
        highlight SpellBad term=underline gui=undercurl guisp=Orange
    endif

- added the :PyflakesUpdate command (runs pyflakes and updates the message area)
- hooked dd, dw, u, and <C-R> to also call :PyflakesUpdate so common text operations will invoke PyFlakes
pyflakes-vim.zip 1.2 2009-03-12 7.0 @kevinwatters - Include compatibility fixes for Python 2.6's _ast changes in visit_FunctionDef and for visit_ExceptHandler. Thanks Herve Cauwelier.
- Include pyflakes.scripts in the "packages" option for setup. Thanks Herve Cauwelier.
- Fix for names incorrectly marked undefined in nested list comprehensions.
- Add "__builtins__" to the list of predefined names.
- Bind names for *args and **kwargs in functions and lambdas.
