powerline-go

Attempted fork of Otann/powerline-go

This application does not cover all features of powerline-shell, only those that I currently use.

For now it is only configurable trough the source recompilation, which is quite fast with Go.

Usage

If you haven't install go, please fallow this.

Then install the binary with

go get github.com/sanyatuning/powerline-go
go install github.com/sanyatuning/powerline-go

Bash

Install powerline-go and add the following to your ~/.bashrc

function _update_ps1() {
   export PS1="$(powerline-go bash $? ${COLUMNS} 2> /dev/null)"
}

export PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"

Zsh

Install powerline-go and add the following to your ~/.zshrc

function powerline_precmd() {
  export PS1="$(powerline-go zsh $? ${COLUMNS} 2> /dev/null)"
}

function install_powerline_precmd() {
  for s in "${precmd_functions[@]}"; do
    if [ "$s" = "powerline_precmd" ]; then
      return
    fi
  done
  precmd_functions+=(powerline_precmd)
}

install_powerline_precmd
