Perl::Critic::Policy::NamingConventions::ProhibitMixedCaseSubs3pm

Write "sub my_function{}" instead of "sub myfunction{}".

Affiliation

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

Overview

Conway's recommended naming convention is to use lower-case words separated by underscores. Well-recognized acronyms can be in ALL CAPS, but must be separated by underscores from other parts of the name.

  sub foo_bar{}   #ok
  sub foo_BAR{}   #ok
  sub FOO_bar{}   #ok
  sub FOO_BAR{}   #ok
  sub Some::Class::foo{}   #ok, grudgingly
  sub FooBar {}   #not ok
  sub FOObar {}   #not ok
  sub fooBAR {}   #not ok
  sub fooBar {}   #not ok

Configuration
