[Howto] Use Powerline on Fedora

Powerline is a status line plugin for Vim, but also a prompt plugin for Bash, ZSH and others. It can easily be installed in Fedora via provided packages.

The status line plugin Powerline is available via the Fedora repositories. There has just been an update which is already available in the testing repository:

$ sudo yum install --enablerepo=updates-testing powerline

The powerline documentation is rather good and explains all steps necessary to configure all the various Powerline plugins. However, note that the string {repository_root} in the examples have to be replaced by /usr/lib/python2.7/site-packages/, so for example {repository_root}/powerline/bindings/vim becomes /usr/lib/python2.7/site-packages/powerline/bindings/vim/. This is due to the fact that the Powerline rpm installs the Powerline code into this specific directory.

So to use Powerline in Vim, just add the following line to the top of your ~/.vimrc:

set rtp+=/usr/lib/python2.7/site-packages/powerline/bindings/vim/

If your previously used other Vim plugins also altering the status line, make sure that you deactivate these.

To use Powerline in Zsh, simply add the following lines to your ~/.zshrc:

# Powerline
if [[ -r /usr/share/powerline/zsh/powerline.zsh ]]; then
  source /usr/share/powerline/zsh/powerline.zsh
fi

In case you use Zsh and want to get rid of the EMACS at the beginning, you need to create a configuration path for Powerline, copy the necessary Shell theme files and alter them accordingly:

$ mkdir -p ~/.config/powerline/themes/shell
$ cp -a /usr/lib/python2.7/site-packages/powerline/config_files/themes/shell/* ~/.config/powerline/themes/shell/

Open the file default.json and remove the lines:

      {
        "function": "powerline.segments.shell.mode"
      },

You might have to restart the powerline-daemon, powerline-daemon -r but afterwards the shell line in Zsh does not contain the current mode anymore. Have fun!
