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.
CREDITS
Initial development of this policy was supported by a grant from the Perl Foundation.
