tCMS/.perlcriticrc

# Troglodyne perlcritic policy, for a distribution that declares use 5.040 or
# later.
#
# There are two of these.  This one is for code that runs on a perl you control,
# and perlcriticrc.compat is for code that runs on whatever perl is already
# installed.  The packaging-perl skill asks which you are writing before it
# copies one, because the answer decides more than this file: it decides the
# use line in every module and test, and perl: in prereqs.yml.
#
# The difference between the two is five policies.  A modern perl refuses what
# they report, so naming them here would buy nothing:
#
#   TestingAndDebugging::RequireUseStrict       strict is on from 5.012
#   Objects::ProhibitIndirectSyntax             no indirect from 5.036
#   InputOutput::ProhibitBarewordFileHandles    no bareword_filehandles from
#   InputOutput::ProhibitBarewordDirHandles       5.038
#   Modules::RequireEndWithOne                  module_true from 5.038
#
# Two more go the same way at 5.042, and are named below because this file
# assumes only 5.040.  Delete them once your floor is 5.041 or later, which
# selects the 5.042 bundle:
#
#   Variables::ProhibitPerl4PackageNames        no apostrophe as a package
#                                                 separator from 5.042
#   CodeLayout::RequireASCII                    source::encoding "ascii" from
#                                                 5.042, which is stricter than
#                                                 the policy and not skippable
#
# tCMS: a policy commented out as #[Name], with no space, is one that the tree
# does not pass yet.  The change that fixes the tree for it enables it.

[ProhibitUnusedImports]
# Modules imported for a side effect rather than for a symbol, which the policy
# cannot see.  `re` is here because every file says `use re '/aa'`.  Add your
# own: IO::Prompter installs prompt() from a custom import rather than @EXPORT,
# and anything loaded by name from a string is invisible the same way.
# tCMS: Exporter, because use Exporter 'import' imports the method that perl
# calls, which no line of the module names.
allow = re Exporter
# Off in a distribution that is only a library: it counts calls from bin/ and
# lib/, and every sub a library exists to offer is called from neither -- a
# module with one public sub and no bin/ reports that sub, which is the policy
# working correctly and saying nothing.  Turn it on for a distribution that also
# ships programs, and add the authordep line to dist.ini when you do.
#
# allow_subs then lists the subs that are called in a way it cannot see: named
# in a string and called as $obj->$name, handed to something else that calls
# them, or called only from a directory it does not read.  Name each one and say
# which, so the next person can tell an exemption from an oversight.
#
#[ProhibitUnusedDefinitions]
#allow_subs =
# A sub that only one subclass uses, and a sub that two subclasses define where
# the class above them defines none.  It reads bin/ and lib/ through
# Perl::Critic::Distribution, as ProhibitUnusedDefinitions does, so the two
# share one parse.  A library whose subclasses live in other distributions
# names in allow_subs each hook that only one of its own subclasses uses.
