NAME Dist::Zilla::Plugin::Bootstrap::lib - A minimal boot-strapping for Dist::Zilla Plug-ins. VERSION version 0.02000000 SYNOPSIS [Bootstrap::lib] try_built = 1 ; try using an existing built distribution named Dist-Name-* no_fallback = 1 ; if try_built can't find a built distribution, or there's more than one, don't bootstrap ; using lib/ instead DESCRIPTION This module does the very simple task of injecting the distributions 'lib' directory into @INC at the point of its inclusion, so that you can use plug-ins you're writing for "Dist::Zilla", to release the plug-in itself. METHODS log_debug 1; plugin_name 'Bootstrap::lib' dump_config sub { } register_component sub { } USE CASES Simple single-phase self-dependency This module really is only useful in the case where you need to use something like dzil -Ilib For *every* call to "Dist::Zilla", and this is mainly a convenience. For that [Bootstrap::lib] on its own will do the right thing. Installed-Only self-dependency The other useful case is when you would normally do dzil build # pass 1 that generates Foo-1.234 with a pre-installed Foo-1.233 dzil -IFoo-1.234/lib build # pass 2 that generates Foo-1.234 with Foo-1.234 For that [Bootstap::lib] try_built = 1 no_fallback = 1 Will do what you want. dzil build # pass1 -> creates Foo-1.234 without bootstrapping dzil build # pass2 -> creates Foo-1.234 boot-strapped from the previous build 2-step self-dependency There's a 3rd useful case which is a hybrid of the 2, where you /can/ build from your own sources without needing a pre-installed version, just you don't want that for release code ( e.g.: $VERSION being "undef" in code that is run during release is "bad" ) [Bootstrap::lib] try_built = 1 fallback = 1 Then dzil build # pass1 -> creates Foo-1.234 from bootstrapped $root/lib dzil build # pass2 -> creates Foo-1.234 from bootstrapped $root/Foo-1.234 PRECAUTIONS DO NOT DO NOT use this library from inside a bundle. It will not likely work as expected, and you DO NOT want to bootstrap everything in all cases. NO VERSION On its own, [Bootstrap::lib] At present, using this module in conjunction with a module with no explicitly defined version in the source will result in the *executed* instance of that plug-in *also* having NO VERSION. If this is a problem for you, then its suggested you try either variation of using [Bootstrap::lib] try_built = 1 ; no_fallback = 1 # SUCKS AT GUESSING The core mechanism behind "try_built" relies on looking in your project directory for a previous build directory of some kind. And there's no way for it to presently pick a "best" version when there are more than one, or magically provide a better solution if there are "zero" versions readily available. This is mostly because there is no way to determine the "current" version we are building for, because the point in the execution cycle is so early, no version plugins are likely to be even instantiated yet, and some version plugins are dependent on incredibly complex precursors ( like git ), so by even trying to garner the version we're currently building, we could be prematurely cutting off a vast majority of modules from even being able to bootstrap. Even as it is, us using "zilla->name" means that if your dist relies on some process to divine its name, the module that does this must * be loaded and declared prior to "Bootstrap::lib" in the "dist.ini" * not itself be the module you are presently developing/bootstrapping The only way of working around that I can envision is adding parameters to "Bootstrap::lib" to specify the dist name and version name... but if you're going to do that, you may as well stop using external plugins to discover that, and hard-code those values in "dist.ini" to start with. STILL NOT REALLY A PLUGIN Though the interface is getting more plugin-like every day, all of the behaviour is still implemented at construction time, practically as soon as the underlying Config::MVP engine has parsed it from the configuration. As such, it is completely removed from the real plugin execution phases, and unlike real plugins which appear on the plugin stash, this module does not appear there. GOOD LUCK I wrote this plug-in, mostly because I was boiler-plating the code into every dist I had that needed it, and it became annoying, especially having to update the code across distributions to handle "Dist::Zilla" "API" changes.
