bash prompt

[boyska]

Our current bash prompt is rather basic. An improved one is not just a vanity feature: it also aids in testing. Especially, it would be good to see the last exit code appear in the prompt.

[boyska]

simple, no colors, exit code at line beginning

export PS1='[\u ($?)] \w \$ '

[AreYouLoco]

advanced, colors, timestamp, exit code, directory

export PS1="${debian_chroot:+($debian_chroot)}[\e[00;33m][\t][\e[0m] $(tput rev)[$(tput sgr0)] \u@\h:[$(tput rev)]\w[$(tput sgr0)][$(tput bold)] $ [$(tput sgr0)]"

[Nhoya]

What about that?

PS1="\[\e[00;37m\]┌─[\t][\[\e[0m\]\[\e[01;31m\]\\$\[\e[0m\]\[\e[00;37m\]]\n└─\\[\e[0m\]\[\e[01;32m\]\u\[\e[0m\]\[\e[00;37m\]@\[\e[0m\]\[\e[01;33m\]\h\[\e[0m\]\[\e[00;37m\]:[\[\e[0m\]\[\e[00;36m\]\w\[\e[0m\]\[\e[00;37m\]]\[\e[0m\]

is a lil more colorful.. but miss the exitcode D:

[Nhoya]

errorc(){
exit_=$?

    if [ $exit_ -ne 0 ]; then
        echo -e "\033[01;31m✘ $exit_\033[0m"
    else echo -e "\033[01;32m✓\033[0m"
        fi
}

who_(){ 
    if [ "$EUID" -ne 0 ]; then
        echo -e "$"
    else
        echo -e "\033[01;31m#\033[0m"
    fi
}


PS1="\u[\[\e[34m\]\w\[\e[m\]]\`errorc\` \`who_\` "

on my computer it does not work properly: it wraps in a strange & wrong way when the line exceeds the width of the window.

[Nhoya]

In wich way? What commands u use?

[Nhoya]

And wich terminal emu? I tested on guake and it works properly

[boyska]

here is a screenshot of how it is "wrong"

[boyska]

this seems to work fine

    promptunicode=1
    freeptoprompt() {
    exit_=$?
    if [[ $promptunicode -eq 1 ]]; then
    ok_symbol=$'\u2713'
    no_symbol=$'\u2717'
    else
    ok_symbol="."
    no_symbol="x"
    fi
    LIGHTGREEN="\[\033[1;32m\]"
    LIGHTRED="\[\033[1;31m\]"
    CYAN='\e[0;36m'
    WHITE="\[\033[0;37m\]"
    RESET="\[\033[0;00m\]"
    dollar="\\$"
    [[ $EUID -eq 0 ]] && dollar="$LIGHTRED$dollar$RESET"
    if [[ $exit_ -eq 0 ]]; then
    last="${LIGHTGREEN}$ok_symbol$RESET"
    else
    last="${LIGHTRED}$no_symbol:$exit_$RESET"
    fi
    PS1="\u[$CYAN\w$RESET]$last $dollar "
    }
    PROMPT_COMMAND=freeptoprompt

It can run in two modes: the default is unicode

the other is ascii-compatible

The default is unicode, but at any time you can switch just setting promptunicode=0

b39ef4a should be ok, with also some minor improvement on the previously-posted screenshot (cyan dirname, better user color handling, local variables everywhere).

I'm wondering if a separate package (submodule) would be appropriate for such a small enhancement.
Pro: modular, updatable for previous freepto users
Con: a package for one file with one dependency (bash-completion) ? Maybe we could aggregate some more stuff in there.
