Perl::...usNames(3pm)

🌸 NAME 🌸

okay so bestie, this is the 3pm manual page for Perl::Critic::Policy::NamingConventions::ProhibitAmbiguousNames — filed under User Contributed Perl Documentation, and the header/footer label is literally Perl::...usNames(3pm) (iconic truncation energy ✨). The policy is giving Don't use vague variable or subroutine names like last or record. 💅 No cap, that's the whole vibe.

🫶 AFFILIATION 🫶

This Policy is part of the core Perl::Critic distribution. periodt. 💖

✨ 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. 😭 the ambiguity is real.

This policy tests against a list of ambiguous words for variable names. lowkey straightforward, highkey useful.

🎀 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. customization slay ✨

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. 🙈 not the false positive jump scare.

my $previous_record = $Foo::last;
