Open Source Python Vi/Vim Software

Powerline is a statusline plugin for vim, and provides statuslines and prompts for several other applications, including zsh, bash, tmux, IPython, Awesome, i3 and Qtile. Powerline was completely rewritten in Python to get rid of as much vimscript as possible. This has allowed much better extensibility, leaner and better config files, and a structured, object-oriented codebase with no mandatory third-party dependencies other than a Python interpreter. Using Python has allowed unit testing of all the project code. The code is tested to work in Python 2.6+ and Python 3. Originally created exclusively for vim statuslines, the project has evolved to provide statuslines in tmux and several WMs, and prompts for shells like bash/zsh and other applications. It’s simple to write renderers for any other applications that Powerline doesn’t yet support. JSON is a standardized, simple and easy to use file format that allows for easy user configuration across Powerline’s supported applications.

UltiSnips is the ultimate solution for snippets in Vim. It has many features, speed being one of them. You should first expand the #! snippet, then the class snippet. The completion menu comes from YouCompleteMe, UltiSnips also integrates with deoplete, and more. You can jump through placeholders and add text while the snippet inserts text in other places automatically: when you add Animal as a base class, __init__ gets updated to call the base class constructor. When you add arguments to the constructor, they automatically get assigned to instance variables. You can then insert your personal snippet for print debugging.
