End of string anchors

Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial.

of course the above regex will match things that are not phone numbers as well:

tutorial/regex2/end_of_string_anchors_needed.p6

use v6;

my $phone = "054-1234567";

if "foo 3-4 bar" ~~ m/ \d '-' \d / {
    say "match others as well";
} 

  • ^ always matches the beginning of the string
  • $ always matches the end of the string
  • + (and *, ?) are the same quantifiers as earlier

tutorial/regex2/end_of_string_anchors.p6

use v6;

my $phone = "054-1234567";

if $phone ~~ m/ ^ \d+ '-' \d+ $ / {
    say "Use anchors and quantifiers";
}


On the other hand if you'd like to match beginning or end of line, those are ^^ and $$. So no need for special mode for this. Also if you want to match a newline you can use \n and if you want to match any character except newline (the old meaning of .) then just use \N.
