Match Any character

The . (dot) is a meta-character that will be ready to match any character. As opposed to the Perl regular expressions in Perl 6 this includes newlines If you want to match any character except newline you can use the \N special character class.

There are also some non-alnum characters that have special meaning though their meaning might be (a bit) different than in PCRE: A . can match any character. Even newline.

#!/usr/bin/perl6
use v6;


my $str = 'The black cat climbed to the green tree.';


if ($str ~~ m/c./) {
    say "Matching '$/'";      # 'ck'
}

my $text = "
The black cat
climebed the greeen tree";

if ($text ~~ m/t./) {
    say "Matching '$/'";     # 't '  with the second ' on a new line
}


if ($text ~~ m/t\N/) {
    say "Matching '$/'";     # 'th'    of the word 'the'
}
