Perl::CriticPerl::Critic::Policy::NamingConventions::ProhibitAmbiguousNames(3)NAMEPerl::Critic::Policy::NamingConventions::ProhibitAmbiguousNames - Don't
use vague variable or subroutine names like 'last' or 'record'.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway lists a collection of English words which are highly ambiguous
as variable or subroutine names. For example, $last can mean previous
or final.
This policy tests against a list of ambiguous words for variable names.
CONFIGURATION
The default list of forbidden words is:
abstract bases close contract last left no record right second set
This list can be changed by giving a value for "forbid" of a series of
forbidden words separated by spaces.
For example, if you decide that "bases" is an OK name for variables
(e.g. in bioinformatics), then put something like the following in
"$HOME/.perlcriticrc":
[NamingConventions::ProhibitAmbiguousNames]
forbid = last set left right no abstract contract record second close
BUGS
Currently this policy checks the entire variable and subroutine name,
not parts of the name. For example, it catches $last but not
$last_record. Hopefully future versions will catch both cases.
Some variable statements will be false positives if they have
assignments where the right hand side uses forbidden names. For
example, in this case the "last" incorrectly triggers a violation.
my $previous_record = $Foo::last;
