Starship.rs: minimal, fast prompt for any shell

What do you mean exactly?

Are you saying it doesn’t get out of date? i.e. you never change the state of the repository outside of your terminal session? I don’t think that’s reflective of how most people work.

Are you saying that it gets out of date but that doesn’t matter? If that’s the case, then it’s a strong hint that the information isn’t as useful as you assume. What’s the point in constantly, repeatedly showing incorrect information?

Are you saying that you work around the problem by hitting enter whenever you want an update? Then aren’t you doing the same thing as your colleagues who you mention struggle with Git? Hitting enter in your case is essentially a shortcut for running `git status` over and over, except you are doing it with literally every command you run instead of only when you need to.

> Also how is "enter" less convenient than literally any other command that you'd still have to type and run to get up-to-date information in a command line?

The issue is the space and attention used by repeatedly showing outdated Git information. Space and attention are at a premium in a terminal window; you can’t just dump all the information available to you in there for free.

Rust is the new C. It communicates that something is fast, but also secure, and new or a modern reimplementation of something old. So, in that sense, is it a user feature because it has established itself in a way that tells the user some important details.

As a result, I've written my own small and concise PS1 which covers all my use cases:

    ## Add this to ~/.bashrc
    force_color_prompt=yes
    ## show: user+hostname (if ssh), conda, venv, guix, and git
    function prompt_command {
        ## styles and symbols
        local RESET='\[\033[0m\]'     ; local BLD_GRN='\[\033[1;32m\]'; 
        local BLD_YLW='\[\033[1;33m\]'; local BLD_PPL='\[\033[1;35m\]';
        local BLD_CYN='\[\033[1;36m\]'; local BLD_WHT='\[\033[1;37m\]'
        local ITL_YLW='\[\033[3;33m\]'; local SEP='⋮'
    
        PROMPT_DIRTRIM=2
        export PS1=""
        if [ -n "$SSH_CONNECTION" ]; then
            PS1=${PS1}${BLD_CYN}'\u'${BLD_YLW}'@'${BLD_GRN}'\h'${RESET}
        fi
        if [ -n "$CONDA_DEFAULT_ENV" ]; then
            PS1=${PS1}${SEP}${ITL_YLW}${CONDA_DEFAULT_ENV}${RESET}
        fi
        if [ -n "$VIRTUAL_ENV" ]; then
            PS1=${PS1}${SEP}${BLD_WHT}${VIRTUAL_ENV##*/}${RESET}
        fi
        if [ -n "$GUIX_ENVIRONMENT" ]; then
            PS1=${PS1}${SEP}${BLD_GRN}'GUIX'${RESET}
        fi
        if [ -e .git ]; then
            PS1=${PS1}${SEP}${BLD_PPL}$(git branch --show-current)${RESET}
        fi
        PS1=${PS1}${SEP}${BLD_GRN}'\w' # short directory
        PS1=${PS1}${BLD_YLW}'▶ '${RESET}
    }
    export PROMPT_COMMAND=prompt_command
