I can't help you with this either. Sorry.

Any reason for not using `~/Mailboxes/**/*.mbox(/)'?

This should be `reply=( $mboxs )'.

No. 177 matches is nothing.

It's zsh-users:23(08|09|10) -- but without a SEGV.

completion killing zsh

[Timothy J Luoma]

Don't ask me why, but when I try this completion (ie: I hit 'tab' after  
'ivvvv' below) zsh dies:

(zsh = 3.1.5-pws-20)



(gdb) run
Starting program: /usr/bin/zsh
# appnmail -ivvvv Program generated(1): Memory access exception on address  
0x2f (protection failure).
0x36d45 in ?? ()
(gdb)

here's the completion:

compctl -K allmbox  'S[-]' -- compactmail appnmail


here's the reply function "allmbox" :

allmbox ()
   {
   if [[ $mboxs = "" ]]
   then
   	mboxs=(`find ~/Mailboxes/ -type d -name '*.mbox' -print`);
   fi
   reply=$mboxs;
   }


what am I doing wrong here?

is it a buffer overflow maybe?

# find ~/Mailboxes/ -type d -name '*.mbox' -print|wc
    177     177   11536

This message looks very familiar, but I can't figure out how to search
for the similar one.  Didn't someone else some months ago ask about a
compctl that had 'S[-]' just sort of floating out there like this?

} compctl -K allmbox  'S[-]' -- compactmail appnmail

Is there an example somewhere on which you based this attempt, that you
can point us to so we can fix it?  More specifically, what gave you the
idea that 'S[-]' would be useful without the -x option?

} when I try this completion (ie: I hit 'tab' after  
} 'ivvvv' below) zsh dies:
} 
} (zsh = 3.1.5-pws-20)

That release is from early June.  There have been at least 60 patches to
zle_tricky.c alone, since then.  The first thing you need to do is grab
at least 3.1.6 from ftp.zsh.org.

} compctl -K allmbox  'S[-]' -- compactmail appnmail
} 
} what am I doing wrong here?

The allmbox function is fine, but that comptl is the same as

	compctl -K allmbox - --
	compctl -K allmbox 'S[-]'
	compctl -K allmbox appnmail
	compctl -K allmbox compactmail

That is, the 'S[-]' and the '--' are being taken as command names.  The
pattern forms like S[-] are only interpreted following a -x option.
That still shouldn't cause a crash (and probably is not a factor), but
it's not doing any good there.

You might have meant something like

    compctl -K allmbox -x 'S[-]' -k '(-i -v)' -- appnmail compactmail

Which means, "complete using the allmbox function UNLESS the current
word starts with '-', in which case complete from the array (-i -v),"
but I don't know quite what you were trying to accomplish.
