Re: filecompletion in ksh93 (fwd)

[Bart Schaefer <schaefer@xxxxxxxxxxx>]

This is interesting; I haven't seen a recent ksh manual.  Looks like ksh
can do "widgets" too, after a fashion.  Use of "trap" on a magic KEYBD
signal to invoke the function is kinda cutesy.

Wrong.  You can.  There might be better solutions than mine here.  This one
works in vi mode, and the next one in emacs.

function vi_tab
{
    # what looks like a space on the next line is a physical tab
    if [[ ${.sh.edmode} == "" && ${.sh.edchar} == "	" ]] then
        .sh.edchar="\\"
    elif [[ ${.sh.edmode} != "" && ${.sh.edchar} == "=" ]] then
        .sh.edchar="=a"
    fi
}

trap 'vi_tab' KEYBD

function emacs_tab
{
    # what looks like a space on the next line is a physical tab
    if [[ ${.sh.edchar} == "	" ]] then
        .sh.edchar=""
    fi
}
