Hello, As I've already mentioned, I've Dist::Zilla and Pod::Weaver plugin bundles for use in my projects (Dist::Zilla::PluginBundle::Author::ASDAGO and Pod::Weaver::PluginBundle::Author::ASDAGO). However, I noticed that prerequisites on other plugins and plugin bundles are not detected by AutoPrereqs. As far as I could tell, there didn't exist any scanners for Perl::PrereqScanner that could scan Dist::Zilla and Pod::Weaver plugin bundles, so I wrote my own.
So far, they work pretty well (the Dist::Zilla one currently only works on Dist::Zilla::Role::PluginBundle::Easy plugin bundles). My working names for them are Perl::PrereqScanner::Scanner::PluginBundle::DistZilla and Perl::PrereqScanner::Scanner::PluginBundle::PodWeaver. Are these names satisfactory? I was also thinking something like Perl::PrereqScanner::Scanner::DistZillaPluginBundle in case they would get confused as plugin bundles for Perl::PrereqScanner itself. What do you think? Also, I think that they're different enough to release as separate packages. Another thing is, the Pod::Weaver plugin bundle scanner works by looking for any anonymous array references of three elements where the last one is an anonymous hash reference. Since plugins could be stored in variables before they are returned from mvp_bundle_config() (indeed, these seems to usually be the case), this is really the only reasonably reliable method of detecting prerequisites short of actually running the file. Unfortunately, this also means there are sometimes false positives. For example, in RJBS's Dist::Zilla plugin bundle, my Pod::Weaver plugin bundle scanner detects two false positives: Pod::Weaver::Section::CPAN-Outdated and Pod::Weaver::Section::RJBS-Outdated. This is because they are specified to add_plugins() as an anonymous array reference of three elements with the last one being an anonymous hash reference, which, you will recall, is exactly what my Pod::Weaver plugin bundle scanner looks for. Of course, the Pod::Weaver plugin bundle scanner should not be run on a Dist::Zilla plugin bundle, but since RJBS's Dist::Zilla and Pod::Weaver plugin bundles are packaged together (which is what I was planning to do with my plugin bundles, though I may rethink that), I don't think it's possible (correct me if I'm wrong) to use different scanners for each file with the AutoPrereqs plugin. One solution would be to write another plugin similar to AutoPrereqs, but that allows per-file scanners to be specified. Another (perhaps better) solution would be to package the Dist::Zilla and Pod::Weaver plugin bundles separately, and use a different scanner for each package. Let me know if you have any opinions on how that should be done. Sorry for the long message (especially the first sentence of the fifth (previous) paragraph), and thanks for any help.

If we accept "For every rule there is an exception" as a rule, then we must concede that there may not be an exception after all, since the rule states that there is always the possibility of exception, and if we follow it to its logical end we must agree that there can be an exception to the rule that for every rule there is an exception. -- Bill Boquist -------- I prefer to send and receive mail encrypted.
