powerline-shell-go

Attempted fork of powerline-shell into Go

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

Usage

Install the binary with

go get github.com/sivel/powerline-shell-go
go install github.com/sivel/powerline-shell-go

Bash

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

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

export PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"

Zsh

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

function powerline_precmd() {
  export PS1="$(powerline-shell-go zsh $? 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

Building on Darwin and with Docker
