I’ve just released a new developer release of Perl::Critic <https://metacpan.org/release/PETDANCE/Perl-Critic-1.127_02>, the static code analysis tool for Perl, as we work toward its first new release in 21 months. This version of Perl::Critic fixes a few bugs and relies on a new release of the underlying Perl parsing library PPI, which also has had its first new release in a while.
This version of Perl::Critic is also ready for the impending release of Perl 5.26, which will no longer include . in @INC by default.
I’ve been spending some time working through the issues in the GitHub project <https://github.com/Perl-Critic/Perl-Critic/issues>, cleaning up what I can and clarifying others.
If you’ve never used Perl::Critic to analyze your code base for potential bugs and stylistic improvements, mostly based on Damian Conway’s Perl Best Practices, try it out.
[Bug Fixes]
* PPI misparsing a module caused an incorrect "Must end with a
recognizable true value." This is fixed by upgrading to PPI
1.224. (GH #696, GH #607)
* A test would fail under the upcoming Perl 5.26 that omits the current
directory from @INC. Thanks, Kent Fredric.
* Fixed an invalid test in the RequireBarewordsIncludes test. Thanks,
Christian Walde. (GH #751)
* If an element contained blank lines then the source "%r" displayed
for a violation was wrong. Thanks, Sawyer X. (GH #702, #734)
[Dependencies]
Perl::Critic now requires PPI 1.224. PPI is the underlying Perl parser
on which Perl::Critic is built, and 1.224 introduces many parsing fixes
such as:
* Fixes for dot-in- at INC.
* Parse left side of => as bareword even if it looks like a keyword or op.
* $::x now works.
* Higher accuracy when deciding whether certain characters are operators or
variable type casts (*&% etc.).
* Subroutine attributes parsed correctly.
[Performance Enhancements]
* Sped up BuiltinFunctions::ProhibitUselessTopic ~7%. Thanks, James
Raspass. (GH #656)
[Documentation]
* Fixed incorrect explanation of capture variables in
ProhibitCaptureWithoutTest. Thanks, Felipe Gasper.
* Fixed incorrect links. Thanks, Glenn Fowler.
* Fixed incorrect example for returning a sorted list. Thanks, @daviding58.
* Fixed invalid POD. Thanks, Jakub Wilk. (GH #735)
* Updated docs on ProhibitYadaOperator. Thanks, Stuart A Johnston. (GH #662)
* Removed all the references to the old mailing list and code repository
at tigris.org. (GH #757)
