Questions tagged [perl]
Perl is a procedural, high-level, general-purpose, dynamic programming language, known for its native support of regular expressions and string parsing capabilities. Please use this tag for questions about Perl in general. For things related to the new (but related) language Raku (formerly "Perl 6"), please use the raku tag. For Perl-style regular expressions in other languages, use the regex tag, or, if they are based on the PCRE library, the pcre tag.
