find real path of a zsh completion function

find real path of a zsh completion function

Hi. I'm trying to write a custom completion function for golang's go
command line, since none that works is available.

First thing I notice is that zsh already ships with a `_go` completion
function (which does not complete the go command) which is installed to
/usr/share/zsh/functions or something. so I rename that file.

now if I write `$ which _go` there is still a _go file somewhere:

_go () {
# undefined
builtin autoload -XUz
}

where is this file coming from? I've already searched through all of my
$fpath dirs.

I've tried:

readlink -f _go
realpath _go
which _go

none of those give me the exact path of this dangling file.

thanks in advance for any help

Make quite sure what fpath compinit is using, i.e. the one you have
set is already in effect at that point. "functions -T compinit" before
running it will output debug.  It will also show if it's using a cached
dump file (value of $_comp_dumpfile), which you can then delete by hand
so it will recreate it --- that would add the autoload without checking
fpath.

print -l ${^fpath}/_go(N)

will show you any _go in the fpath.

Did you restart the shell before doing "which _go"?  Removing a file
does not remove the autoload definition for it.

Try:

    autoload +X _go

If that gives an error, there is no such file.  If it succeeds, then:

    whence -v _go

will tell you the file from which it was loaded (in recent versions of
zsh, anyway).
