Raku Tips ‘n Tricks
This week was inspired by another of jubilatious1 one-liners: Replace the nth from end occurrence of a string … but the examples here are elaborated as regular code:
my $s = "a1 b2 c3 d4";
say ($s ~~ m:1st/\d/).Str; # → 1
say ($s ~~ m:2nd/\d/).from; # → 4
say ($s ~~ m:3rd/<[a..z]>\d/); # → ｢c3｣
say ($s ~~ m:nth(4)/\w/).Str; # → 2
The key feature here is the Regex Positional Adverb family, :1st, :2nd, :3rd and :nth(). See if you can work out how each line does its job to pick out the first digit, start position of the second, letter-digit pair of the third and the fourth character respectively.
See https://docs.raku.org/language/regexes#Positional_adverbs for more information.
Your contribution is welcome, please make a gist and share via the #raku channel on IRC or Discord.
