Python-mode, a Python IDE for Vim

This project needs contributors.

Documentation:

:help pymode
https://github.com/python-mode/python-mode/wiki

Important notes:

From 2017-11-19 onwards python-mode uses submodules instead of hard coding 3rd party libraries into its codebase. Please issue the command: git submodule update --init --recursive inside your python-mode folder.
From 2019-12-14 onwards python-mode dropped python2 support. If you still need to use it with python2 you should look for the last-py2-support branch and/or tag.

If you are a new user please clone the repos using the recursive flag:

git clone --recurse-submodules https://github.com/python-mode/python-mode

Python-mode is a Vim plugin that magically converts Vim into a Python IDE.

Why Python-mode?

Be more productive: Pymode saves time by bringing all the tools necessary for professional developers so that you can focus on bigger things. It has been finely tuned based on decades of experience working with Vim and is constantly kept up to date.
Get smart assistance: Pymode knows all about your code. We use the best-in-class intellisense code completion, on-the-fly error checking and quick-fixes; easy project navigation and much more.
Use the full power and capabilities of Vim: Unlike traditional IDEs which can only provide a small subset of Vim functionalities, you can do everything and anything that you can in Vim.
Modular structure: We attempt to create Python-mode with the same principles of python: i.e. have a modular structure, so that as and when better libraries evolve, we can provide you the best experience, while abstracting the details so that you can get back to what you do best.
Written mostly in Python: 96.1% written in Python. Well, we love Python :)

The plugin contains all you need to develop python applications in Vim.

Support Python and 3.6+
Syntax highlighting
Virtualenv support
Run python code (<leader>r)
Add/remove breakpoints (<leader>b)
Improved Python indentation
Python motions and operators (]], 3[[, ]]M, vaC, viM, daC, ciM, ...)
Improved Python folding
Run multiple code checkers simultaneously (:PymodeLint)
Autofix PEP8 errors (:PymodeLintAuto)
Search in python documentation (<leader>K)
Code refactoring
Intellisense code-completion
Go to definition (<C-c>g)
And more, more ...

To read python-mode documentation in Vim, use :help pymode.

Requirements

Vim >= 7.3 (most features needed +python3 support) (also --with-features=big if you want g:pymode_lint_signs).

How to install

Manually (according to vim's package structure)

As of vim8 there is an officially supported way of adding plugins. See :tab help packages in vim for details.

cd ~/.vim/pack/python-mode/start
git clone --recurse-submodules https://github.com/python-mode/python-mode.git
cd python-mode

Note. Windows OS users need to add -c core.symlinks=true. See below.

pathogen

cd ~/.vim
mkdir -p bundle && cd bundle
git clone --recurse-submodules https://github.com/python-mode/python-mode.git

Enable pathogen in your ~/.vimrc:

" Pathogen load
filetype off

call pathogen#infect()
call pathogen#helptags()

filetype plugin indent on
syntax on

vim-plug

Include the following in the vim-plug section of your ~/.vimrc:

Plug 'python-mode/python-mode', { 'for': 'python', 'branch': 'develop' }

NeoBundle

Add the following:

" python-mode: PyLint, Rope, Pydoc, breakpoints from box.
" https://github.com/python-mode/python-mode
NeoBundleLazy 'python-mode/python-mode', { 'on_ft': 'python' }

Manually

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

Then rebuild helptags in vim:

:helptags ~/.vim/doc/

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

Troubleshooting/Debugging

First read our short FAQ or using :help pymode-faq. If your question is not described there then you already know what to do (because you read the first item of our FAQ :) ).

Nevertheless just a refresher on how to submit bugs:

(From the FAQ)

Clear all python cache/compiled files (*.pyc files and __pycache__ directory and everything under it) from your python-mode install directory.

In Linux/Unix/MacOS you can run:

find <path_to_pymode> -type f -iname '*.pyc' -o -iname '*.pyo' -delete && find . -type d -name '__pycache__' -delete

Then start python mode with:

vim -i NONE -u <path_to_pymode>/debugvimrc.vim

Reproduce the error and submit your python mode debug file. You can check its location with :messages for something like:

pymode debug msg 1: Starting debug on: 2017-11-18 16:44:13 with file /tmp/pymode_debug_file.txt

Please submit the entire content of the file along with a reasoning of why the plugin seems broken.

Do check for sensitive information in the file before submitting.

Please, also provide more contextual information such as:

your Operational System (Linux, WIndows, Mac) and which version
the vim --version output
which is your default python (python --version)
the python version that vim has loaded in your tests:
- :PymodePython import sys; print(sys.version_info) output.
and if you are using virtualenvs and/or conda, also state that, please.
It would be good also to provide the output of the two following commands:
git status (under your python-mode directory)
tree <python-mode-directory> or something similar (such as ls -lR)

Frequent problems

Read this section before opening an issue on the tracker.

Python 2/3 vim support

Vim has issues to work with both python2 and python3 at the same time, so if your VIM is compiled with support to both version you may find problems. The best way to handle it is to build your vim again with only python3 support. Here is a good reference on how to build vim from source.

Python 3 syntax

python-mode supports only python3, so, if you are using python2 we cannot help you that much. Look for our branch with python2-support (old version, not maintained anymore) (last-py2-support).

Symlinks on Windows

Users on Windows OS might need to add -c core.symlinks=true switch to correctly clone / pull repository. Example: git clone --recurse-submodules https://github.com/python-mode/python-mode -c core.symlinks=true

Error updating the plugin

If you are trying to update the plugin (using a plugin manager or manually) and you are seeing an error such as:

Server does not allow request for unadvertised object

Then we probably changed some repo reference or some of our dependencies had a git push --force in its git history. So the best way for you to handle it is to run, inside the python-mode directory:

git submodule update --recursive --init --force
git submodule sync --recursive
