1. Intro ~
*pymode-intro*
Python-mode is a vim plugin that allows you to use the pylint, rope, and pydoc
libraries in vim to provide features like python code bug checking,
refactoring, and some other useful things.
This plugin allows you to create python code in vim very easily. There is no
need to install the pylint or rope libraries on your system.
Python-mode contains all you need to develop python applications in Vim.
Features: *pymode-features*
- Support Python version 2.6+ and 3.2+
- Syntax highlighting
- Virtualenv support
- Run python code (``<leader>r``)
- Add/remove breakpoints (``<leader>b``)
- Improved Python indentation
- Python folding
- Python motions and operators (``]]``, ``3[[``, ``]]M``, ``vaC``, ``viM``,
``daC``, ``ciM``, ...)
- Code checking (pylint_, pyflakes_, pylama_, ...) that can be run
simultaneously (``:PymodeLint``)
- Autofix PEP8 errors (``:PymodeLintAuto``)
- Search in python documentation (``K``)
- Code refactoring <rope refactoring library> (rope_)
- Strong code completion (rope_)
- Go to definition (``<C-c>g`` for `:RopeGotoDefinition`)
- And more, more ...
==============================================================================
2. Common functionality ~
*pymode-common*
This script provides the following options that can customizes the behavior of
PythonMode. These options should be set in your |vimrc|.
Below shows the default values.
Turn on the whole plugin *'g:pymode'*
>
let g:pymode = 1
Turn off plugin's warnings *'g:pymode_warnings'*
>
let g:pymode_warnings = 1
Add paths to `sys.path` *'g:pymode_paths'*
Value is list of path's strings.
>
let g:pymode_paths = []
Trim unused white spaces on save *'g:pymode_trim_whitespaces'*
>
let g:pymode_trim_whitespaces = 1
Setup default python options *'g:pymode_options'*
>
let g:pymode_options = 1
If this option is set to 1, pymode will enable the following options for
python buffers: >
setlocal complete+=t
setlocal formatoptions-=t
if v:version > 702 && !&relativenumber
setlocal number
endif
setlocal nowrap

checkers. You could run several similar checkers.
Pymode uses Pylama library for code checking. Many options like skip
files, errors and etc could be defined in `pylama.ini` file or modelines.
Check Pylama documentation for details.
Pylint options (ex. disable messages) may be defined in `$HOME/pylint.rc`
See pylint documentation.

==============================================================================
3. Rope support ~
*pymode-rope*
Pymode supports Rope refactoring operations, code completion and code assists.
Commands:
|:PymodeRopeAutoImport| -- Resolve import for element under cursor
|:PymodeRopeModuleToPackage| -- Convert current module to package
|:PymodeRopeNewProject| -- Open new Rope project in current working directory
|:PymodeRopeRedo| -- Redo changes from last refactoring
|:PymodeRopeRegenerate| -- Regenerate the project cache
|:PymodeRopeRenameModule| -- Rename current module
|:PymodeRopeUndo| -- Undo changes from last refactoring
Turn on the rope script *'g:pymode_rope'*
>
let g:pymode_rope = 1
.ropeproject Folder ~
*.ropeproject*
*:PymodeRopeNewProject* [<path>] -- Open new Rope project in the given path
*:PymodeRopeRegenerate* -- Regenerate the project cache
Rope uses a folder inside projects for holding project configuration and data.
Its default name is `.ropeproject`. It is recommended that you do not add the
.ropeproject folder to version control system.
Currently it is used for things such as:
* The config.py file in this folder contains project configuration. Have
a look at the default config.py file (which is created when it
does not exist) for more information.
* It can be used for saving project history, so that the next time you open the
project you can undo past changes.
* It can be used to save information about object inferences.
* It can be used to save a global name cache, which is used for auto-import.
By default, if `.ropeproject` is not found in the current directory, rope will
look recursively for it in parent folders.
Warning: If rope finds `.ropeproject` in a parent dir, it will use it with
all its child directories, which may slow scanning down (because of many,
possibly unrelated, files)
Enable searching for |.ropeproject| in parent directories
*'g:pymode_rope_lookup_project'*
>
let g:pymode_rope_lookup_project = 0
You can also manually set the rope project directory. If not specified rope will
use the current directory.
*'g:pymode_rope_project_root'*
>
let g:pymode_rope_project_root = ""
The location of the `.ropeproject` folder may also be overridden if you wish to
keep it outside of your project root. The rope library treats this folder as a
project resource, so the path will always be relative to your project root (a
leading '/' will be ignored). You may use `'..'` path segments to place the
folder outside of your project root.
*'g:pymode_rope_ropefolder'*
>
let g:pymode_rope_ropefolder='.ropeproject'
Show documentation for element under cursor ~
Show documentation for object under cursor. *'g:pymode_rope_show_doc_bind'*
Leave empty to disable the key binding.
>
let g:pymode_rope_show_doc_bind = '<C-c>d'
Regenerate project cache on every save (if file has been modified)
>
let g:pymode_rope_regenerate_on_write = 1
------------------------------------------------------------------------------
4.1 Completion ~
*pymode-completion*
By default you can use <Ctrl-Space> for autocompletion. The first entry will
be automatically selected and you can press <Return> to insert the entry in
your code. <C-X><C-O> and <C-P>/<C-N> works too.
Autocompletion is also called by typing a period in |Insert| mode by default.
Turn on code completion support in the plugin *'g:pymode_rope_completion'*
>
let g:pymode_rope_completion = 1
Turn on autocompletion when typing a period
*'g:pymode_rope_complete_on_dot'*
>
let g:pymode_rope_complete_on_dot = 1
Keymap for autocomplete *'g:pymode_rope_completion_bind'*
>
let g:pymode_rope_completion_bind = '<C-Space>'
Extended autocompletion (rope could complete objects which have not been
imported) from project *'g:pymode_rope_autoimport'*
>
let g:pymode_rope_autoimport = 0
Load modules to autoimport by default *'g:pymode_rope_autoimport_modules'*
>
let g:pymode_rope_autoimport_modules = ['os', 'shutil', 'datetime']
Offer to unresolved import object after completion.
>
let g:pymode_rope_autoimport_import_after_complete = 0
------------------------------------------------------------------------------
4.2 Find definition ~
*pymode-rope-findit*
By default when you press *<C-C>g* on any object in your code you will be moved
to definition.
Leave empty for disable key binding. *'g:pymode_rope_goto_definition_bind'*
>
let g:pymode_rope_goto_definition_bind = '<C-c>g'
Command for open window when definition has been found
Values are (`e`, `new`, `vnew`) *'g:pymode_rope_goto_definition_cmd'*
>
let g:pymode_rope_goto_definition_cmd = 'new'
------------------------------------------------------------------------------
4.3 Refactoring ~
*pymode-rope-refactoring*
Rename method/function/class/variable in the project ~
Pymode can rename everything: classes, functions, modules, packages, methods,
variables and keyword arguments.
Keymap for rename method/function/class/variables under cursor
*'g:pymode_rope_rename_bind'*
>
let g:pymode_rope_rename_bind = '<C-c>rr'
Rename a current module/package ~
*:PymodeRopeRenameModule* -- Rename current module
Keymap for rename current module *'g:pymode_rope_rename_module_bind'*
>
let g:pymode_rope_rename_module_bind = '<C-c>r1r'
Imports ~
*:PymodeRopeAutoImport* -- Resolve import for element under cursor
Organize imports sorts imports, too. It does that according to PEP8. Unused
imports will be dropped.
Keymap *'g:pymode_rope_organize_imports_bind'*
>
let g:pymode_rope_organize_imports_bind = '<C-c>ro'
Insert import for current word under cursor *'g:pymode_rope_autoimport_bind'*
Should be enabled |'g:pymode_rope_autoimport'|
>
let g:pymode_rope_autoimport_bind = '<C-c>ra'
Convert module to package ~
*'g:pymode_rope_module_to_package_bind'*
*:PymodeRopeModuleToPackage* -- convert current module to package
Keybinding:
>
let g:pymode_rope_module_to_package_bind = '<C-c>r1p'
Extract method/variable ~
*pymode-rope-extract*
Extract method/variable from selected lines.
*'g:pymode_rope_extract_method_bind'*

let g:pymode_rope_extract_method_bind = '<C-c>rm'
let g:pymode_rope_extract_variable_bind = '<C-c>rl'
Use function ~
*pymode-rope-use*
It tries to find the places in which a function can be used and changes the
code to call it instead.
>
let g:pymode_rope_use_function_bind = '<C-c>ru'
Move method/fields ~
*pymode-rope-move*
It happens when you perform move refactoring on a method of a class. In this
refactoring, a method of a class is moved to the class of one of its
attributes. The old method will call the new method. If you want to change all
of the occurrences of the old method to use the new method you can inline it
afterwards.

==============================================================================
6. FAQ ~
*pymode-faq*
Python-mode doesn't work
------------------------
Open any python file and run ":call pymode#troubleshooting#test()",
fix the warning or send me the output.
Rope completion is very slow *pymode-rope-slow*
----------------------------
Rope creates a project-level service directory in |.ropeproject|
If ``.ropeproject`` is not found in the current directory, rope will walk
upwards looking for a ``.ropeproject`` in every dir of the parent path. If
rope finds ``.ropeproject`` in a parent dir, it sets the project for all child
dirs and the scan may be slow for so many dirs and files.
Solutions:
- Delete `.ropeproject` from the parent dir to make rope create `.ropeproject`
in the current dir.
- Run ``:PymodeRopeNewProject`` to make rope create ``.ropeproject`` in the
current dir.
- Set |'g:pymode_rope_lookup_project'| to 0 for prevent searching in parent
dirs.
You may also set |'g:pymode_rope_project_root'| to manually specify the project
root path.
Pylint check is very slow
-------------------------
In some projects pylint may check slowly, because it also scans imported
modules if possible. Try using another code checker: see
|'g:pymode_lint_checkers'|.
You may set |exrc| and |secure| in your |vimrc| to auto-set custom settings
from `.vimrc` from your projects directories.
OSX cannot import urandom
-------------------------
See: https://groups.google.com/forum/?fromgroups=#!topic/vim_dev/2NXKF6kDONo
The sequence of commands that fixed this:
>
brew unlink python
brew unlink macvim
brew remove macvim
brew install -v --force macvim
brew link macvim
brew link python
