zfinit problem in ksh emulation mode

zfinit problem in ksh emulation mode

Hi,

I have a problem running zfinit in ksh emulation ( running zsh as a link
from /usr/bin/ksh )

When I try:

user@zambezi: autoload -U zfinit
user@zambezi: zfinit
zsh: zfinit: function not defined by file

However if I run zsh like this (which I'm not allowed to do in scripts)

user@zambezi: /bin/zsh
[user@zambezi]/usr/share/zsh% autoload -U zfinit
[user@zambezi]/usr/share/zsh% zfinit
[user@zambezi]/usr/share/zsh% zfparams puma jro PassW0rd
[user@zambezi]/usr/share/zsh% zfopen
[user@zambezi]/usr/share/zsh% zfls
.kshrc
.rhosts
.jrrc_hp
.ssh

It all works fine. So it is potentially possible.

Is there some option I can set in my script so that when my script runs as:

#!/usr/bin/ksh

That this will work ...

Thanks in advance,

Jerry

"autoload -Uz zfinit" is a better bet, to force zsh-style autoload.

Unfortunately we're not very consistent about using those flags in the
distributed functions, so while it'll probably run it might not do the
trick with the other zftp functions since zfinit currently runs just
"autoload -U ..." with the effects you've just seen.  I'll apply a very
boring patch that fixes up every autoload under Functions in the
distribution, unless anybody knows of an exception (which would surprise
me).

Until then, you might want to modify zfinit by hand to replace all the
"autoload -U"s with "autoload -Uz".  After that you might be OK, since I
was more successful with putting "emulate -L zsh" at the top of functions.

The obvious one to try is "unsetopt kshautoload".

Thanks Peter, I can't change all the installation, I did try the -Uz zfinit
but then it failed with zfparams: function not defined.

I may be out of luck until they install an updated copy here!

zfinit:42: command not found: compctl
zfinit:50: command not found: compctl
zfinit:51: command not found: compctl
zfinit:52: command not found: compctl
zfinit:53: command not found: compctl
zfinit:58: command not found: compctl
zfinit:67: command not found: compctl

I can still write the scripts to run on my system but will have to wait for
a new version of zsh here before I can write production scripts

Thanks for the answer!

Cheers,

Jerry

You can copy zfinit somewhere earlier in your FPATH, which you might
need to set explicitly in your script (fpath doesn't work in ksh mode).

You don't need compctl.  I think the problem is simply that it's not
autoloaded (as a builtin from a library) in ksh mode.  This a rather
different issue and compctl is thouroughly out of date anyway; I probably
need to check if compctl is present.  This should be harmless, in fact.
