Perl::CrPerl::Critic::UsercContributedxPerlsDocumentationBracesForMultiline(3) NAME Perl::Critic::Policy::RegularExpressions::RequireBracesForMultiline - Use "{" and "}" to delimit multi-line regexps. AFFILIATION This Policy is part of the core Perl::Critic distribution. DESCRIPTION Long regular expressions are hard to read. A good practice is to use the "x" modifier and break the regex into multiple lines with comments explaining the parts. But, with the usual "//" delimiters, the beginning and end can be hard to match, especially in a "s///" regexp. Instead, try using "{}" characters to delimit your expressions. Compare these: s/ <a \s+ href="([^"]+)"> (.*?) </a> /link=$1, text=$2/xms; vs. s{ <a \s+ href="([^"]+)"> (.*?) </a> } {link=$1, text=$2}xms; Is that an improvement? Marginally, but yes. The curly braces lead the eye better. CONFIGURATION There is one option for this policy, "allow_all_brackets". If this is true, then, in addition to allowing "{}", the other matched pairs of "()", "[]", and "<>" are allowed.
