} Is it possible when defining a shell function as a user defined
} widget to access the prefix argument?
I posted a patch to pass the prefix argument as a positional parameter,
but Zefram objects to using the positional parameters of widget functions
and so didn't include it in the release.
There are also several bugs (all of which I reported, search the archive)
involving widget functions that invoke others via the "zle" command, one
of which causes the prefix arg to get bizarre (usually very large) values.
} Also, is there any way when calling a builtin widget to figure out
} the status? For example, I'd like to do "zle complete-word" in my
} widget and then determine if:
}
} - it completed something
} - there were no completions
} - choices were listed
} - choices had already been listed and it did nothing
I believe my patch also arranges to return a sensible exit code from the
"zle" command based on the return of the widget that is called, but I
don't recall for certain and I think Zefram objected to this as well.
