Powerline-lua
Incomplete port of the excellent https://github.com/justjanne/powerline-go
A goal is to have it working for (d)ash as well as bash to enjoy a nice prompt on those openWRT and alpine systems where a go binary is just too big.
Aiming for compatibility with powerline-go to keep things simple, and compatibility with lua 5.1 for openWRT.
Examples
busybox ash
Must be compiled with ASH_EXPAND_PRMT=y
Just add to .profile (or similar):
POWERLINE_LUA_PATH=/path/to/this/repo
# Add path to repo so lua require() finds it's way:
export LUA_PATH="$POWERLINE_LUA_PATH/?.lua;;"
PS1='$($POWERLINE_LUA_PATH/powerline.lua -e $?)'bash
Bash supports extra stuff so it's possible to calculate the duration a command took, but it makes for a bit longer snippet to add to .bashrc, so it is added separately in ./bash/powerline-lua.sh
Just add to .bashrc:
POWERLINE_LUA_PATH=/path/to/this/repo
source "${POWERLINE_LUA_PATH}/bash/powerline-lua.sh"License
