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
Pier Paolo Grassi

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
