Perl-Critic Policies for simple and isolated Refactoring-Support.
This Perl-Crictic Policy-Modules should help where to start a safe refactoring in old leagacy Perl code.
The McCabe complexity check within the standard Perl-Critic Module are a good overall starting point see:
- Perl::Critic::Policy::Modules::ProhibitExcessMainComplexity
- Perl::Critic::Policy::Subroutines::ProhibitExcessComplexity
but these are for some bigger scans, so these new policies should check (or begin) in smaller chunks:
- ProhibitReturnBooleanAsInt - return boolean as int "return 1;"
- ProhibitConditionComplexity - condition complexity "if/while/for/... (...){}"
- ProhibitManyConditionsInSub - subs has many conditionals "if, while, for, ..."
- ProhibitLargeBlock - large code block as statement count "{...}"
- ProhibitBlockComplexity - code block complexity "{...}"
- ProhibitLargeSub - large subs as statement count
To install this module, run the following commands:
perl Build.PL
./Build
./Build test
./Build install
Each policy has its own detailed documentation.
Please report bugs on GitHub.
