_normal:26: bad math expression: operator expected at `0 '

[Roman Neuhauser]

Hi there,

after about six months of using about 0.01% of the goodies zsh offers,
I decided it was time to checkout compinit. The exploration ended up
before it started with an error I don't know what to think about (I can
read some basic shell scripting, but that's about it). Also note that
I've searched the archives, but only found unrelated messages.

At this moment, I'm supposed to be impressed. :)

It does that for ^I completion as well. What's up?

We had this in one of the CVS-versions, but it has long been fixed.
Where did you get that version from? Anyway, try it with either one of
the stable versions or with the latest CVS.

And *then* be impressed. Or something.

Check your $fpath to see if it's possibly picking up other versions of
the function.

It's hard to see how this problem can occur in 4.0.4, unless there's
some additional option we should be setting for compatibility in the
list given by $_comp_options.  If it really is the function from 4.0.4,
try running `emulate zsh' before starting and using the new completion
system.  If it works after that, it would help if you send a list of
options you've got set.

Installed from the port (/usr/ports/shells/zsh/).

Snippet from the port Makefile:

MASTER_SITES=   ${MASTER_SITE_SOURCEFORGE} \
        ftp://ftp.zsh.org/%SUBDIR%/ \
        ftp://ftp.sterling.com/%SUBDIR%/ \
        ftp://ftp.rge.com/pub/shells/%SUBDIR%/ \
        ftp://ftp.fu-berlin.de/pub/unix/shells/%SUBDIR%/ \
        ftp://ftp.ips.oz.au/pub/packages/%SUBDIR%/ \
        ftp://ftp.uit.no/pub/unix/shells/%SUBDIR%/

The port fetches zsh-4.0.4-doc.tar.gz zsh-4.0.4.tar.gz from the first
available site in the list above.

Pity the function definition files don't contain $Id$, it'd be clear
what version of the file that is.

Also of interest might be my `uname -a`, but I first tried compinit (and
found the bug) on a fresh 4.5-STABLE (zsh-4.0.4 as well).

So, is 4.0.4 not a stable version?

This is the one.  I think this applies cleanly to 4.0, but it's obvious
how to do it by hand anyway.

You can fix it simply by editing the installed compinit to add
NO_octalzeroes to _comp_options.

I don't think that's possible. 4.0.4 is the only version that this box
has ever seen:

    You've nailed it down, thanks! Let me know if you need anything else.

    Done that, and now I'm really impressed. :)
    BTW, I wanted to thank to everybody for this great piece of
    software. zsh has changed my life. :)
