Powerline – Tweak statusline in Terminal

Powerline is a statusline plugin for vim, and provides statuslines and prompts for several other applications, including zsh, bash, tmux, IPython, Awesome and Qtile. To install the utility, open a terminal and run this command:

sudo dnf install powerline

Next, configure your bash shell to use powerline by default. Add the following snippet to your ~/.bashrc file:

if [ -f `which powerline-daemon` ]; then
  powerline-daemon -q
  POWERLINE_BASH_CONTINUATION=1
  POWERLINE_BASH_SELECT=1
  . /usr/share/powerline/bash/powerline.sh
fi

To activate the changes, open a new shell or terminal.

Features

• Extensible and feature rich, written in Python. 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.
• Stable and testable code base. Using Python has allowed unit testing of all the project code. The code is tested to work in Python 2.6+ and Python 3.
• Support for prompts and statuslines in many applications. 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.
• Configuration and colorschemes written in JSON. JSON is a standardized, simple and easy to use file format that allows for easy user configuration across all of Powerline’s supported applications.
• Fast and lightweight, with daemon support for even better performance. Although the code base spans a couple of thousand lines of code with no goal of “less than X lines of code”, the main focus is on good performance and as little code as possible while still providing a rich set of features. The new daemon also ensures that only one Python instance is launched for prompts and statuslines, which provides excellent performance.
