My Powerline setup and configuration

2 minute read

If you’re working in an enterprise environment, and you don’t have the admin rights on your Windows desktop to install additional fonts, or your enterprise admin cannot do that, then I suggest you to ignore this post, powerline will be installed, but very ugly. If you have a Linux desktop, all will be OK, installing fonts doesn’t need to be root.

Installing powerline-status from pip

pip3 install powerline-status --user
pip3 show powerline-status
user_python_site_packages=$(pip3 show powerline-status | grep Location: | awk '{print $2}')
powerline_global_config_files_path="$user_python_site_packages/powerline/config_files"
mkdir -p ~/.config/powerline
cp -r $powerline_global_config_files_path/. ~/.config/powerline

Installing fonts

https://powerline.readthedocs.io/en/latest/installation/linux.html#fonts-installation

apt install fontconfig
mkdir -p ~/.local/share/fonts/
mkdir -p ~/.config/fontconfig/conf.d/
wget https://github.com/powerline/powerline/raw/develop/font/PowerlineSymbols.otf
wget https://github.com/powerline/powerline/raw/develop/font/10-powerline-symbols.conf
mv PowerlineSymbols.otf ~/.local/share/fonts/
fc-cache -vf ~/.local/share/fonts/
mv 10-powerline-symbols.conf ~/.config/fontconfig/conf.d/

Adding VIM support

If Python support is absent then Vim needs to be compiled with it. To do this use --enable-pythoninterp ./configure flag (Python 3 uses --enable-python3interp flag instead). Note that this also requires the related Python headers to be installed. Please consult distribution’s documentation for details on how to compile and install packages.

Check VIM with python support:

vim --version | grep +python

if you don’t have +python or +python3, you can install VIM from source by enable python support: https://github.com/ycm-core/YouCompleteMe/wiki/Building-Vim-from-source

Add following lines to $HOME/.vimrc:

python3 from powerline.vim import setup as powerline_setup
python3 powerline_setup()
python3 del powerline_setup

Adding Ipython support

https://powerline.readthedocs.io/en/latest/usage/other.html#ipython-prompt

Doesn’t work for ipython v7+: https://github.com/powerline/powerline/issues/1953

Adding PBD support

https://powerline.readthedocs.io/en/latest/usage/other.html#pdb-prompt

Adding Bash support

https://powerline.readthedocs.io/en/latest/usage/shell-prompts.html#bash-prompt

Add following lines to ~/.bashrc:

python path must be available before powerline-daemon -q

powerline-daemon -q
POWERLINE_BASH_CONTINUATION=1
POWERLINE_BASH_SELECT=1
. {repository_root}/powerline/bindings/bash/powerline.sh

Adding Git support
