Afternoon all, I'm trying to to a regular expression to search and
replace + with \+
I need to escape the + because it is getting used as an operator
instead of a literal string, this is what I have so far:
$terms[$i] =~ s/\+ /\ \\\+/g;
Basically the result of searching for c++ should return results
containing that string.
I'm not sure about what you really need. Please consider the
following:
$_ = 'the c++ programming language';
print '$_ contains "c++"', "\n" if /\Qc++/;
s/\+/\\+/g;
print;
Outputs:
$_ contains "c++"
the c\+\+ programming language
