since i haven't seen any discussions here, i'd like to start by sending my config !

lmk if there's any room for improvement :3

Looks nice! Someday I'll release all the scripting-specific scaffolding I load on startup, but besides all that, the only thing I have in my .profile that's interesting is this:

function my_prompt {
    integer lastrc=$?
    # Save .sh.match so we can reference it later in the shell
    typeset oldshmatch=${.sh.match}
    # Add red return code if it's not 0
    if (( lastrc > 0 ))
    then
        printf "\033[01;31m$lastrc\033[00m:"
    fi
    # If at $HOME, replace with '~'
    if [[ $PWD == $HOME ]]
    then
        printf "\033[01;32m~\033[00m\$ "
    else
        printf "\033[01;32m${PWD##*/}\033[00m\$ "
    fi
    # Restore old .sh.match
    [[ $oldshmatch == * ]]
}

export PS1="\$(my_prompt)"

}

}

function DATEANDTIME.get {

function RAND.get {
    .sh.value=$(($RANDOM / 32767.0))

function UNIXTIME.get {
    .sh.value=$(printf "%(%s)T")
}

this is quite fascinating ! i assume you script in ksh lots ?

[dnewhall]

Yes. Outside of some "real programs" written in C# or Common Lisp, almost everything that I've written outside of work (and doesn't require a GUI) has been scripted in Ksh93 since...2010? I literally have my own "package manager" I use to maintain my collection of Ksh libraries. I have been cleaning them up to release, but there's a lot of unfinished cruft in there...

i'd love to see that actually ! a genuine sophisticated ksh program sounds awesome
