} If e.g. the result of last pattern mathing is
} available (much like in Perl) as, say, ``pattern'' array
I'd name it something other than `pattern' ... what's in the array is not
the patterns, it's the matched substring of the source string, right?
} I am not sure, that there is easy
} way in Zsh to extract matched subpattern currently)
There is ${(MSI:n:)...#...}, where n is a number. BTW, it looks like (M)
doesn't work right with ${.../...}. Am I missing something?
zagzig% x="abcdefghij"
zagzig% echo ${x/??}
cdefghij
zagzig% echo ${(M)x/??}
cdefghij
zagzig% echo ${(MS)x/??}
cdefghij
zagzig% echo ${(MSI:1:)x/??}
cdefghij
zagzig% echo ${(MSI:2:)x/??}
adefghij
zagzig% echo ${(RSI:2:)x/??}
adefghij
echo ${(MSI:2:)x//??}
ab
zagzig% echo ${(M)x#??}
ab
zagzig% echo ${(MSI:2:)x#??}
