In this tutorial, we will show you how to setup Vim to use Python-mode in Linux to develop Python applications in Vim editor.
How to Install Python-mode for Vim in Linux
Start by installing Pathogen (makes it super easy to install plugins and runtime files in their own private directories) for easy installation of Python-mode.
Run the commands below to get the pathogen.vim file and the directories it needs:
# mkdir -p ~/.vim/autoload ~/.vim/bundle && \
# curl -LSso ~/.vim/autoload/pathogen.vim https://tpo.pe/pathogen.vim
Then add the following lines below to your ~/.vimrc file:
execute pathogen#infect()
syntax on
filetype plugin indent on
Once you have installed pathogen, and you can now put Python-mode into ~/.vim/bundle as follows.
# cd ~/.vim/bundle
# git clone https://github.com/klen/python-mode.git
Then rebuild helptags in vim like this.
:helptags
You need to enable filetype-plugin (:help filetype-plugin-on) and filetype-indent (:help filetype-indent-on) to use python-mode.
Install Python-mode in Debian and Ubuntu
Another way you can install python-mode in Debian and Ubuntu systems using PPA as shown.
$ sudo add-apt-repository https://klen.github.io/python-mode/deb main
$ sudo apt-get update
$ sudo apt-get install vim-python-mode
If you you encounter the message: “The following signatures couldn’t be verified because the public key is not available”, run the command below:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys B5DF65307000E266
Now enable python-mode using vim-addon-manager like so.
$ sudo apt install vim-addon-manager
$ vim-addons install python-mode
Customizing Python-mode in Linux
To override the default key bindings, redefine them in the .vimrc files, for instance:
" Override go-to.definition key shortcut to Ctrl-]
let g:pymode_rope_goto_definition_bind = "<C-]>"
" Override run current python file key shortcut to Ctrl-Shift-e
let g:pymode_run_bind = "<C-S-e>"
" Override view python doc key shortcut to Ctrl-Shift-d
let g:pymode_doc_bind = "<C-S-d>"
Note that python-mode uses python 2 syntax checking by default. You can enable python 3 syntax checking by adding this in your .vimrc.
let g:pymode_python = 'python3'
You can find additional configuration options on the Python-mode Github Repository: https://github.com/python-mode/python-mode
