`^foo' matches anything except the pattern `foo' (require extendedglob).
See man zshexpn | less -p "Glob Operators" for more details.

(You mean globbing pattern, not regular expression, right?)

Use ^pat, which excludes everything matching pat, or pat1~pat2, which
selects based on pat1, then excludes based on pat2.  These require
extendedglob.  For example,

setopt extendedglob
print -l ^*.o

You can also "setopt kshglob" and use the ksh forms that bash now
understands.  These tend to be clumsier.

See the list of "Glob Operators" in the zshexpn manual page.

For a regex, I don't know, but you can select the files that don't
match a glob pattern. The natural way is to follow the pattern with ~
and the pattern that represent the files you don't want.

Suppose you want to match all files except those matching *.pdf :
*~*.pdf

Suppose you want to match *.pdf except t*.pdf, just write
*.pdf~t*.pdf

And that's it.

Careful with the term "regex".  Although zsh extendedglob patterns are
semantically equivalent to regular expressions, they don't follow the
usual regular expression syntax.  Which do you really mean?

If you literally mean a perl-like regular expression, and you have the
pcre module available, it'd be something like:

  zmodload zsh/pcre
  setopt extendedglob
  pcre_compile "negpat"
  echo *(e:'pcre_match "$REPLY" && reply=() || reply=($REPLY)':)

(replacing "negpat" with your desired regex, obviously).

The more usual way would be to write it as one of two forms of glob
pattern:

  ^negpat		(requires extendedglob)
  pospat~negpat

The differences are subtle, and get two whole pages [*] in "From Bash to
Zsh".  The first matches any file name other than "negpat".  The second
matches file names with "pospat", then removes those strings that match
"negpat".  The first matches files within a single level of directory
hierarchy.  The negpat part of the second can match across directories,
if the pospat part contains slashes.  These differences are especially
important if you combine the ^negpat form with other patterns, e.g., as
in xyz(^PDQ)*, which will match xyzPDQzyx because the empty substring
between xyz and PDQ is a match for (^PDQ) and PDQzyx is matched by "*".

The pcre_match example above works mostly like the pospat~negpat form,
because files are first found by globbing and then discarded by pattern
matching; but pcre_match is invoked as each file is examined, whereas
in pospat~negpat the string removal is done at the end after globbing
has finished.  This could be important if the pospat uses **/ for tree
searching.

[*] But not two consecutive pages.

Sure.  Just run "setopt" with no arguments.  For a more detailed list,
first run "setopt ksh_option_print" and then "setopt".

} >ls *.csv

Try "print *.csv" as well, just to see what you get.  It may be that "ls"
is hiding something from you.

Hm.  That would mean that it believes it has all the default settings.
(The normal behavior is to print only the options that have changed.)
However, that should be impossible, because "interactive" is not a
default and if that's not set then you wouldn't even have a prompt.
You should see at least:

interactive
shinstdin

And probably also "zle", and given how you're starting the shell you
should also see "login".

} It's as thought setopt isn't functionning
} I start with cygwin.bat
} zsh --login -i

It'd be helpful if you started up "zsh -fx" to be reasonbly sure that
there isn't some kind of alias or function wrapper for setopt.  (The -x
will cause trace output if there's an /etc/zshenv or equivalent being
loaded.)

} BTW in the doc I find both
} 
} setopt extended_glob
} and
} setopt extendedglob

Yes, and in "man zshoptions" you'll find the first two paragraphs are:

    Options are primarily referred to by name. These names are case
    insensitive and underscores are ignored. For example, `allexport'
    is equivalent to `A__lleXP_ort'.

    The sense of an option name may be inverted by preceding it with
    `no', so `setopt No_Beep' is equivalent to `unsetopt beep'. This
    inversion can only be done once, so `nonobeep' is not a synonym
    for `beep'.  Similarly, `tify' is not a synonym for `nonotify'
    (the inversion of `notify').

Thanx Bart,
replying to your post which hasn't appeared yet!

zsh -fx

solved all my problems

setopt returned a list of options
I was able to setopt extendedglob
and
ls *.csv~yy.csv now works,


>>>Try to run  zsh -fx  and see what happens.  The option -f 
(NO_RCS) tells zsh to ignore all initialization files except 
/etc/zshenv; -x turns on XTRACE, which tells zsh to 
print everything what is done. 


so now to work out what is frigomatic with my existing settings!

I suggest first renaming all your ~/.z* files (so that zsh won't find
them on startup), then run zsh normally.  If the problem persists, it's
with one of the /etc/z* files.

If the problem goes away when you've renamed your ~/.z* files, then start
renaming them back to their original names one at a time, starting a new
zsh after each rename until the problem reappears.  Then you'll know what
file you have to look at.

Once you know what file, start chopping it up by inserting "return 0"
about half way through that file.  If the problem persists, it's in the
top half, so move the "return 0" to 1/4 of the way through; if not,
move the "return 0" to 3/4 of the way through.  Continue bisecting the
problem portion of the file until you isolate the problem.

You might also run zsh with -x (but without -f) to see all the commands
it's executing during startup.

} /etc/zshenv just has a return 0 (which I was supposed to remove but I
} don't pick up my ~/.zshenv if I do)

That's odd in and of itself.  Do you mean that if you "rm /etc/zshenv"
then your ~/.zshenv is not read, or do you mean that if you delete the
"return 0" then ...?  If the latter, is there really nothing else in
/etc/zshenv, that is, it's empty except for "return 0"?

You're sure there's not, for example, an assignment to ZDOTDIR or HOME
in /etc/zshenv?

What other /etc/z* files do yo have?
