Regex: matching any Number then a hyphen

on Nov 27, 2022 at 12:50 UTC ( #11148404=perlquestion: print w/replies, xml ) Need Help??

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I have lines of data, all begin with a number. For lines which have a " - " or " " after the number, but before the next piece of text I'd like to replace this with a ". ". example data
1234 - Foo 56778 Bar 9999. Baz
desired output
1234. Foo 56778. Bar 9999. Baz

    Hi,

    What did you try? How did it fail?

    use strict; use warnings; use utf8; use Test::More tests => 3; for my $line(<DATA>) { chomp $line; my ($string, $wanted) = split '#', $line; $string =~ s/^(\d+)\s*[-](.*)/$1.$2/; is $string, $wanted; } __END__ 1234 - Foo#1234. Foo 56778 Bar#56778. Bar 9999. Baz#9999. Baz
    Output:
    1..3 ok 1 ok 2 ok 3

    Hope this helps!


    The way forward always starts with a minimal test.
