Remove multiple characters after match

Remove multiple characters after match

Hi,

I want to remove space at the begin and end of a match, and I thought
this should work, but it doesn't:

```
% x=( 'abc ,,*.i,, 123' 'abc ,, *.i,, 123' 'abc ,,    *.i,, 123' 'abc ,,*.i ,, 123' 'abc ,,*.i   ,, 123' 'abc ,,   *.i   ,, 123' )
% print -l -- -${(*)^${(*)x#*,, #}%% #,,*}-
-*.i-
- *.i-
-    *.i-
-*.i-
-*.i-
-   *.i-
```

How can I remove the spaces after the left delimiter?


Regards Jörg

You're trying to get the shortest match for (*) and the longest match
for ( #), which doesn't work.  I think your best bet is to first
remove all the spaces around delimiters:

${(*)x// #,, #/,,}

And then leave space matching out of the # and % constructions:

% print -l -- -${(*)^${(*)${(*)x// #,, #/,,}#*,,}%,,*}-
-*.i-
-*.i-
-*.i-
-*.i-
-*.i-
-*.i-

You didn't actually say what output you wanted but I think that's it?

Ahh. That makes sense. Thanks for this explanation.

Yes, that's it. In the end I used this code to make entering for loops
easier, e.g. `git -C ,, ~/git/*(/),, grep …`. Zsh is really cool!

```
accept-line()
{
    case "$BUFFER" in
      *,,?*,,*)
        BUFFER="for i in ${${${BUFFER#*,,}## #}%% #,,*}; do ${BUFFER/,,?*,,/\$i}; done"
        ;;
    esac
    zle .accept-line
}
zle -N accept-line
```

Thanks and regards,

Jörg
