swline

Cute shell
How I installed it:

$ sudo mkdir /git
$ sudo chmod a+rw /git
$ cd git
$ git clone https://git.swee.codes/swee/swline.git
$ sudo ln -s /git/swline/swline /usr/local/bin/swline

add this to your bashrc I guess

function _update_ps1() {
    PS1=$(swline $?)
}

if [[ ! $PROMPT_COMMAND =~ _update_ps1 ]]; then
    PROMPT_COMMAND="_update_ps1; $PROMPT_COMMAND"
fi
