NAME
Perl::Critic::Policy::Variables::ProhibitPunctuationVars - Write $EVAL_ERROR instead of $@.AFFILIATION
This Policy is part of the core Perl::Critic distribution.DESCRIPTION
Perl's vocabulary of punctuation variables such as $!, $., and $^ are perhaps the leading cause of its reputation as inscrutable line noise. The simple alternative is to use the English module to give them clear names.$| = undef; #not ok use English qw(-no_match_vars); local $OUTPUT_AUTOFLUSH = undef; #ok
CONFIGURATION
The scratch variables $_ and @_ are very common and are pretty well understood, so they are exempt from this policy. The same goes for the less-frequently-used default filehandle "_" used by stat(). All the regexp capture variables ($1, $2, ...) are exempt too.You can add more exceptions to your configuration. In your perlcriticrc file, add a block like this:
[Variables::ProhibitPunctuationVars] allow = $@ $!
The "allow" property should be a whitespace-delimited list of punctuation variables.
BUGS
This doesn't find punctuation variables in strings. RT #35970.AUTHOR
