Applied to grml-etc-core.git, fixed in git therefore.
Will be closed by upload of new grml-etc-core version.
Thanks!

ogg2mp3 isses now has it's own bug:
http://bts.grml.org/grml/issue997

documentation patch as requested

moved current version of my simple-extract out of file mentioned in the link
below. so here's the current version: http://paste.grml.org/427/
it's still not pretty though. (although much better than the original)
please improve or extend at your convenience

changed the script to use 
for ARCHIVE in "${@}" 
in case you give it another look after the release.

Instead of posting the changed version into pastezone, for now I'll leave you
with a link to my changed .zshrc because I still have hope that I will find the
time to improve upon that big ugly if else fi block somewhen in the future.

`$*' is something entirely different, yes. I've written a lengthy page
in zsh's wiki that explains some of the subtle differences between $*
and $@, double-quoted or not.

"$@" (the quoted form) however is rock solid. And also very
idiomatic. So idiomatic in fact that there's a short hand:

  % for i in "$@"; do ...; done

and

  % for i; do ...; done

are the same.

Also, while-shift is destructive with respect to $@. for-"$@" is not.

Regards, Frank

right. "$@" does not have word splitting problems even on (ba)sh

$* on the other hand will separate by IFS, which is a problem if e.g. you have
filenames with spaces.

so yeah, if you meant "$@" then you are right, it just comes down to habituation
in this case.

No it does not.

Although I meant

for i in "$@"; do ...

But neither has any word splitting problems.

Regards, Frank

as for: 
for i in *; do something-with $i; done
versus
while $1...shift?

the former has word splitting problems in propably just about any shell
scripting language other than zsh. So I consider it bad practise in shell
scripts in general. (Don't want to get too used to the comforts of zsh in case I
need to write a sh script again)

the later has control flow problems, since you absolutely must not forget the
"shift" when you use "continue". But at least it also save miniscule amounts of
memory ;->

rewrote it without the use of eval, but it's even longer and uglier now than the
initial version where each archive type appeared in two case/esac.
at least it's easily extendable for new archive types

posting it here just for your viewing pleasure ;-)
http://paste.grml.org/410/

mhh, good points.
I resorted to using eval since there seems to be no other way to "evaluate" a
process substitution inside a variable. This is possible with (e) for many
substitutions, but not for process subst.
I would be very interessted to hear if there are better way's to do this. Maybe
I too will ask around a bit on #zsh.

As for documentation: sure no problem
As for testing: I did extensive testing, but not on grml.

anyway, looking forward to the new release :-)
Getting back to you on this issue, if I can improve the function.

Also, `eval' should never be used. I mean...

  % simple-extract 'foo.tar.gz;echo I could have rmed your \~.gz'

We've been talking about this a little on IRC, and it's probably not
worth going through a lot of trouble to save one manual `wget'.

Not with `eval' in any case.

I like the general tone of this one. Two things though: First, since
this is a substantial change - and although I didn't see anything fishy
in it - we're close to a release right now, so how well did you test
this? :-)

And second: Since you've extended the function's behaviour, could you
also update the manual in `doc/grmlzshrc.t2t' accordingly, please?

How about

for i in *; do something-with $i; done

Instead of while $1...shift?

also: in my .zshrc.local I have defined
alias se=simple-extractor

which is very useful ;-)
e.g. 
# se http://blabla/sourfile.tar.bz2

here is the ogg2mp3 patch

discovered that above mentionend functions are a bit outdated.
ogg2mp3 doesn't work as advertised on my system, maybe lame changed behaviour ?
the archive functions don't know about xz and the simple-extractor can generally
use some overhowl.

beside fixing the above, I rewrote simple-extractor so that:
* it behaves consistently for all archive types (no more deleting of source file
or not depending on archive type e.g. .gz vs .tar.gz)
* it takes filepaths as well as URIs
* it handles more archive types
* it optionally deletes the source archive
