Re: Regexp conundrum

use of unintialised value in pattern match (m//)... An undefined value was used as if it were already defined

You know, it is helpful if you indicate where the warning occurs.

my $pattern1 =~ /(word)-(spacing):\s*[\d]+px/; # word spacing regexp
my $pattern2 =~ /(letter)-(spacing):\s*[\d]+px/;   # letter spacing re
+gexp

What's that supposed to do? You are matching against undefined variables.

if(/$pattern1 && $pattern2/)

You haven't defined $pattern1 and $pattern2 yet. But if you do, the code above most likely doesn't do what you think it does.

How may I initialise the variables? A literal string within quotes? Much of the code I wrote didn't make much sense, so I've cut the unnecessary stuff out. Live and learn... Richard	[reply]

If the intention is to later interpolate them into a regexp, I'd go for a literal string. A `qr` construct works too, but that may be less efficient (it depends on how the interpolation happens). Abigail	[reply]
