[OT] Perl: exec and $variables
Hello
I have a problem with some perl code. I know this is off-topic, but
there are numerous knowledgeable people on deb-usr, so forgive me for
posting this.
Now to my problem.
Given the following variable,
my $BEGINREGEX = "sprintf(\"^<!-- // begin of news\$no // !-->\$\")";
the following eval() call doesn't substitute $no for what it is and
return the new string with the substituted $no in it:
my $no = 1;
my $bla = eval($BEGINREGEX);
print "$bla\n";
$bla is empty for some reason.
So how would I go about having $no substituted in $BEGINREGEX for
whatever it happens to be set to at a particular point in the script?
Cheers!
Sven
