use v6;
my $phone = "054-1234567";
# You can also create named regexes:
my regex prefix { \d ** 2..3 }
my regex number { <+digit - [0]> \d ** 6 }
# if $phone ~~ m/^ <prefix> '-' <number> $/ {
# but this does not work now so we write the full syntax:
if $phone ~~ m/^ <prefix=&prefix> '-' <number=&number> $/ {
say "prefix $/<prefix> number: $/<number>";
}
# as you can see $/ is also a hash
let's create the named regexes for the word and duplicate:
tutorial/regex2/named_regex2.p6
use v6;
my $s = 'The elvish brown fox jumped over the the lazy dog';
my regex word { \w+ [ \' \w+]? }
my regex dup { << <word=&word> \W+ $<word> >> }
if $s ~~ m/ <dup=&dup> / {
say "Found '{$<dup><word>}' twice in a row";
}
