PWS: reload

[zzapper]

PWS,

It'd be really useful if your reload function would "find" the script whereever it might lie in the
path.
I've tried the
autoload =somescript but it doesn't seem to work.

reload doesn't work on scripts, it works on functions.

It doesn't matter where the function lives in the path; you don't refer to
it by the full path anyway, just the function name.

Functions doen't live in $path, like scripts, they live in $fpath, so =
won't find them.

Sorry PWS
AYS it does work from "anywhere", isn't it frustrating when one jumps to a conclusion!!

It's for functions, not scripts.  I don't know what feature you're
talking about; it works fine if the function is already marked for
autoloading.  Do you mean you want to be able either to autoload or
reload with the same function?  You can use "autoload foo; reload foo".

P,
I never remember that I need to say autoload the first time of use that's all.

You might want to ignore the result of unfunction.

reload() {
while (( $# )); do
  unfunction $1 2>/dev/null
  autoload $1
  shift
done
}

or something.

Can I have a warning that the function wasn't already loaded?

We're venturing into the realm of "you should be able to do this yourself."

E.g., just take out the 2>/dev/null

Or:

reload() {
while (( $# )); do
  unfunction $1 2>/dev/null || print -u2 "$1 loading for the first time"
  autoload $1
  shift
done

Or whatever ...

Richtig aber,  as reload is I believe of general interest I though this way we'd get the best
version!

function reload() {
# reload your changed autoloaded function(s)
if (( $# == 0 ));
then
    print "Reload what?" >&2
    return 1
fi
while (( $# )); do
    unfunction $1 2>/dev/null || print -u2 "$1 loading for the first time"
    autoload $1
    shift
done
}
