zsh-4.2.1: Bug in zparseopts ?

[Dieter Lambrecht]

Hi,

script

#! /bin/zsh

emulate -L zsh

set -- -c 1
echo "New set:" $@
zparseopts -a args -A Args 'c:'
echo "c:" ${args[@]} "|" ${(kv)Args[@]}

echo "***********"
set -- --c 2
echo "New set:" $@

zparseopts -E -a args -A Args '--c+:'
echo "--c:" ${args[@]} "|" ${(kv)Args[@]}

zparseopts -E -a args -A args '\-c+:'
echo "\-c:" ${args[@]} "|" ${(kv)Args[@]}

zparseopts -E -a args -A args '-c+:'
echo "\-c:" ${args[@]} "|" ${(kv)Args[@]}


gives the following output:


New set: -c 1
c: -c 1 | -c 1
***********
New set: --c 2
--c: |
\-c: |
./t5.sh:zparseopts:20: missing option descriptions
\-c: |




"The Z Shell manual" p. 213 states that name='-files' should recognise GNU long options like "--files". However, I could not parse these options whith zparseopts.



Kind Regards,

Dieter Lambrecht

Try:

    zparseopts -E -a args -A args -- '-c+:'

It's not exactly obvious from the documentation, but you must use "--"
to signal the end of the options of zparseopts and the beginning of the
descriptions of the options it should parse.  (Or list at least one
description that does not begin with a "-" before listing any that do.)
