As an addition to our ongoing investigation into static code analysis tools for a Perl programming we are maintaining, can anyone recommend a certain tool that he/she is experienced with?
We are already actively using perl::critic (Perl::Critic) and rats (https://www.fortify.com/ssa-elements/threat-intelligence/rats.html\), but results have been unsatisfactorily: suggestions given are too general or too contrived in the code at hand.
We are looking to check our programs for adherence to generally accepted coding practices, input validation checks, spotting dead code and perhaps some performance improvements.
perl-lint? perl -w ?
We invariably have the -w directive on, certainly during testing. Lint is something we are aware of, but haven't used yet and is on our list now. Thank you for the response.
