non-greedy match

non-greedy match

Hello, is it possibile to force non greedy matching for globbing
expressions?
I use this code to replace interactively some template labels:

str='{{{a}}}{{{b}}}'
tmp=
while [[ $str == (#b)(*)'{{{'(*)'}}}'(*) ]]
do
  vared -p "$match[2]: "  tmp
  str=$match[1]$tmp$match[3]
done
echo $str

I would like for them to be presented in the order they occur in $str, I
get them backward instead

thanks

Only within a parameter expansion.  So something like

str='{{{a}}}{{{b}}}'
hack=$str
tmp=
unset match # or local -a match if in a function
while hack=${(S)hack/(#b)(*)'{{{'(*)'}}}'(*)} && [[ -n $match ]]
do
  vared -p "$match[2]: "  tmp
  str=$match[1]$tmp$match[3]
  hack=$str$hack
  unset match
done
echo $str
