in reply to How to access main package global vars in modules

There are several alternative one line changes that do what you ask, such as:

  • Declare $glbA and $glbB with our in functions.pl
  • Refer to those variables in functions.pl with the fully qualified $main::glbA and $main::glbB
  • no strict "vars"

But none of the above is recommended. You would be much better in most scenarios to make functions.pl a package, and pass lexical variables as parameters to its functions.

[haukex]: here's the code that uses it
[Corion]: haukex: Hmm - maybe I can reuse that. I see that it uses Pod::Parser, which I think was one of the more fragile parsers. But if I'm statically (re)generating the tests instead of doing that "live" on the client/tester machines, that's a much smaller...
[Corion]: ... problem space than trying to cater to all versions of Pod::Parser(s)
[haukex]: I think you're right, I think Pod::Simple is the preferred parser now
[haukex]: But I was just using it as an author test anyway
[Corion]: haukex: Aaah - I thought you were still running these tests on every machine, but you only run these as author or Devel::Cover tests
[Corion]: haukex: Yeah, I think back then I used Test::Inline, which used a pod parser that was going through some changes and I didn't want to cater for all the various versions and thus stopped testing the Pod completely
[choroba]: I usually do this with presentations
[Corion]: But now I think statically (re)generating the Pod tests is a saner approach, and likely I'll regenerate the tests either in Makefile.PL or from xt/ but have them live below t/
[choroba]: I keep the snippets in files of their own, and use a Makefile to syntax highlight them and insert them into slides, while also running them and inserting the output if required
