in reply to Common module lib across Perl versions on same system

David Farrell started a new project called berrybrew that was leveraging the portable editions of Strawberry Perl to provide something like perlbrew for Windows. See here for his blog post about it.

Someone else, stevieb, forked the project to add other functionality. According to his blog (see here), he merged his changes back into David Farrell's code base.

Although, I haven't used it yet myself, I think that berrybrew could provide most of what you want to accomplish. Since you already have Perl versions installed, I'm not sure how to get berrybrew to pick up and work with your Perl installations. Perhaps you can submit a ticket and get help/suggestions on how to do that from David and/or stevieb.

    Thanks. I've heard of berrybrew, but I was under the assumption is just helped manage different instances of Perl - which I do already. It'd still have the same issue of having to install non-core modules in each version of Perl, correct?

      stevieb here, the person who took over and now maintains berrybrew (thanks for the mention, dasgar!).

      At this time, there is no built-in way to manage external lib directories outside of each Perl instance, but it is on my roadmap (after I get my RasPi work completed).

      Personally, I like each instance to have its own installation of modules, but I digress. It's been requested of me to build in the ability that you're asking for, and as I said, it's on the roadmap. For now, you can do what you're doing, or shift out @INC (unshift @INC, '/path/to/libs'). Some modules will break, others won't.

      If you want an easy way to install a module on all Perl instances with berrybrew and avoid using a single lib dir:

      berrybrew exec cpanm Module::Name

      That'll install the module on all installed Perl instances. If you have a module to install but it won't work on some version, I've added in the ability to exec on certain versions only (NOTE: no space between the perl versions!):

      berrybrew exec --with 5.24.0_64,5.10.1_32 cpanm Module::Name

      If you have any problems or issues, or want to discuss options on how you'd like to see a lib option be implemented, feel free to open an issue on the berrybrew link above (my github), or message me here and I can send over my email address.

      update: To boot, if you're working with Strawberry Perl portable editions, you can incorporate them into berrybrew by copying/moving the instance directory into c:\berrybrew directory, and ensure that it is named exactly the same as one of the entries in berrybrew available. Thereafter, you can clone it to whatever name you want. I did not get as far in the Perl registration logic to allow just dumping any old directory into the berrybrew dir and have it auto-register, but that feature isn't far off either./update
