zmodload zmv ?

zmodload zmv ?

[Nick Croft]

zmv looks to be a very handy utility. With Debian, it's located
under /usr/share/zsh/4.0.4/functions/Misc  .

I've tried starting it with zmodload zmv - nothing.

I've moved, chowned, and chmodded it to a local fpath.

What's the trick? All the googling points to the same paragraph being
quoted. The source contains a pretty good description of its uses but no
hint as to startup.

It tries to do something if I explicitly quote the path in the command
line. But emulating the example produced the following

        nicko@work ~/tmp % ../.myfns/zmv '(*).bmp '$1.BMP'
        ../.myfns/zmv: emulate: command not found
        ../.myfns/zmv: local can only be used in a function
        ../.myfns/zmv: typeset: unknown option: `-A'
        ../.myfns/zmv: integer: command not found
        ../.myfns/zmv: setopt: command not found

I imagine those calls would work without problems if it could be loaded 
with zmodload.

zmodload is for shared library objects, not shell functions.  You want
`autoload zmv'.

Try "man zshcontrib", or "info zsh" and look at the "User Contributions"
section.

At a guess, running it as a shell script is trying to feed it to /bin/sh
rather than to /bin/zsh, which simply won't work.

zmodload is for loading dynamic code into zsh.  For your platform, ".so"
files.

"man zshmodules"

fpath/FPATH is searched for an undefined (-u) function; see zshparam(1).
To create such a function, use the autoload builtin; see zshbuiltins(1).

There are some example startup files which ship with zsh; you'll need to
check your package to see if they were included.

The example zshrc includes:

-----------------------------< cut here >-------------------------------
# Where to look for autoloaded function definitions
fpath=($fpath ~/.zfunc)

# Autoload all shell functions from all directories in $fpath (following
# symlinks) that have the executable bit on (the executable bit is not
# necessary, but gives you an easy way to stop the autoloading of a
# particular shell function). $fpath should not be empty for this to
# work.
for func in $^fpath/*(N-.x:t); autoload $func
-----------------------------< cut here >-------------------------------

For comparison, dating back a while, I have:
 autoload ${^fpath}/*(N:t)
and mine is broken.  I thought that I had the executable check in;
obviously I lost it at some point in the past few years.  Oops!

Someone else might be able to explain why it's better to loop over the
expanded list, autoload'ing each, rather than "autoload glob".

I could recommend this line in your startup:
for func in $^fpath.zwc(N-.r:); autoload -U -w $func

then all functions are loaded at startup at little cost.

Dennis, Phil, Bart:

Thanks. I took the autoload option.
