Re: Use of uninitialized value when using regex

Shorter (parentheses saved and used here); arguably 'more straightforward' or 'maintainable':

my $txt="Version=2010-09-01_17-29-04 Build=26";

my ($build) = $txt =~ /(?:=)(\d+)$/;

print $build;
[download]

Output: 26

More maintainable? You changed `/=(\d+)$/` into `/(?:=)(\d+)$/`. How's that more straightforward or maintainable? What's the point of grouping a single character?	[reply] [d/l] [select]
