Python-mode, Python in VIM

Python-mode is a vim plugin that allows you to use the pylint, rope, pydoc, pyflakes libraries in vim to provide features like python code looking for bugs, refactoring and some other useful things.

This plugin allow you create python code in vim very easily. There is no need to install the pylint, rope or any used python library on your system.

• Highlight syntax errors
• Highlight and auto fix unused imports
• Strong code completion
• Code refactoring
• Python documentation
• Run python code
• Go to definition
• Powerful customization
• Virtualenv support
• And more...

Requirements

• VIM >= 7.0 with python support (also --with-features=big if you want use g:pymode_lint_signs)

How to install

Using pathogen (recomended)

% cd ~/.vim
% mkdir -p bundle && cd bundle
% git clone git://github.com/klen/python-mode.git

• Enable pathogen in your ~/.vimrc:

  " Pathogen load
  filetype off
  
  call pathogen#infect()
  call pathogen#helptags()
  
  filetype plugin indent on
  syntax on
  

Manually

% git clone git://github.com/klen/python-mode.git
% cd python-mode.vim
% cp -R * ~/.vim

Then rebuild helptags in vim:

:helptags ~/.vim/doc/

Note

filetype-plugin (:help filetype-plugin-on) and filetype-indent (:help filetype-indent-on) must be enabled for use python-mode.

Settings

Note

Also you can see vim help. :help PythonModeOptions

To change this settings, edit your ~/.vimrc:

" Disable pylint checking every save
let g:pymode_lint_write = 0

" Set key 'R' for run python code
let g:pymode_run_key = 'R'

Show documentation

Default values:

" Load show documentation plugin
let g:pymode_doc = 1

" Key for show python documentation
let g:pymode_doc_key = 'K'

" Executable command for documentation search
let g:pydoc = 'pydoc'

Run python code

Default values:

" Load run code plugin
let g:pymode_run = 1

" Key for run python code
let g:pymode_run_key = '<leader>r'

Code checking

Default values:

" Load pylint code plugin
let g:pymode_lint = 1

" Switch pylint or pyflakes code checker
" values (pylint, pyflakes)
let g:pymode_lint_checker = "pylint"

" Pylint configuration file
" If file not found use 'pylintrc' from python-mode plugin directory
let g:pymode_lint_config = "$HOME/.pylintrc"

" Check code every save
let g:pymode_lint_write = 1

" Auto open cwindow if errors be finded
let g:pymode_lint_cwindow = 1

" Auto jump on first error
let g:pymode_lint_jump = 0

" Place error signs
let g:pymode_lint_signs = 1

" Minimal height of pylint error window
let g:pymode_lint_minheight = 3

" Maximal height of pylint error window
let g:pymode_lint_maxheight = 6

Note

Pylint options (ex. disable messages) may be defined in $HOME/pylint.rc See pylint documentation: http://pylint-messages.wikidot.com/all-codes

Rope refactoring library

Default values:

" Load rope plugin
let g:pymode_rope = 1

" Auto create and open ropeproject
let g:pymode_rope_auto_project = 1

" Enable autoimport
let g:pymode_rope_enable_autoimport = 1

" Auto generate global cache
let g:pymode_rope_autoimport_generate = 1

let g:pymode_rope_autoimport_underlineds = 0

let g:pymode_rope_codeassist_maxfixes = 10

let g:pymode_rope_sorted_completions = 1

let g:pymode_rope_extended_complete = 1

let g:pymode_rope_autoimport_modules = ["os","shutil","datetime"])

let g:pymode_rope_confirm_saving = 1

let g:pymode_rope_global_prefix = "<C-x>p"

let g:pymode_rope_local_prefix = "<C-c>r"

let g:pymode_rope_vim_completion = 1

let g:pymode_rope_guess_project = 1

let g:pymode_rope_goto_def_newwin = 0

let g:pymode_rope_always_show_complete_menu = 0

Other stuff

Default values:

" Load breakpoints plugin
let g:pymode_breakpoint = 1

" Key for set/unset breakpoint
let g:pymode_breakpoint_key = '<leader>b'

" Autoremove unused whitespaces
let g:pymode_utils_whitespaces = 1

" Auto fix vim python paths if virtualenv enabled
let g:pymode_virtualenv = 1

" Set default pymode python indent options
let g:pymode_options_indent = 1

" Set default pymode python fold options
let g:pymode_options_fold = 1

" Set default pymode python other options
let g:pymode_options_other = 1

" Enable pymode's custom syntax highlighting
let g:pymode_syntax = 1

Default keys

Note

Also you can see vim help :help PythonModeKeys

Keys	Command
K	Show python docs
<C-Space>	Rope autocomplete
<Leader>r	Run python
<Leader>b	Set, unset breakpoint

Note

See also :help ropevim.txt

Commands

Note

Also you can see vim help :help PythonModeCommands

Command	Description
:Pydoc <args>	Show python documentation
PyLintToggle	Enable, disable pylint
PyLintCheckerToggle	Toggle code checker (pylint, pyflakes)
PyLint	Check current buffer
Pyrun	Run current buffer in python

Note

See also :help ropevim.txt

F.A.Q.

Rope completion is very slow

To work rope creates a service directory: .ropeproject. If g:pymode_rope_guess_project set (by default) and .ropeproject in current dir not found, rope scan .ropeproject on every dir in parent path. If rope finded .ropeproject in parent dirs, rope set project for all child dir and scan may be slow for many dirs and files.

Solutions:

• Disable g:pymode_rope_guess_project to make rope always create .ropeproject in current dir.
• Delete .ropeproject from dip parent dir to make rope create .ropeproject in current dir.
• Press <C-x>po or :RopeOpenProject to make force rope create .ropeproject in current dir.

Pylint check is very slow

In some projects pylint may check slowly, because it also scan imported modules if posible. Try use pyflakes, see :h 'pymode_lint_checker'.

Note

You may set exrc and set secure in your vimrc for auto set custom settings from .vimrc from your projects directories. Example: On Flask projects I automaticly set g:pymode_lint_checker = "pyflakes", on django g:pymode_lint_cheker = "pylint"
