Dist::Zilla::App::Command::bakeini - bake dist.ini to not need the bundles.
version 0.001004
cp dist.ini dist.ini.meta dzil bakeini less dist.ini # no more bundles :D
There's several long standing point of contention surrounding the use of bundles.
A few poignant ones that bother me are:
Bundles change over time and configuration parameters can change in validity
For example, I might add a requirement in a later incarnation of a bundle that a given parameter be specified. But that creates a confusing backwards compatibility problem for people who merely want to check out and build the code.
Some contributors tend not to like dealing with bundles due to bundle complexity
Bundles often declare far more dependencies than contributors need to build one specific distribution, and the bundle obscures the visibility of what plugins are being used.
This also manifests as a difficulty to work around problems produced by bundles such as bundles use-ing broken modules, which is not straight forward to iron out with the @Filter bundle.
use
@Filter
@Filter is also complicated for end users who are not familiar with dzil to use, and @Filter also lacks abilities to re-order plugins if that is necessary to avoid a bug.
dzil
Additionally, routing configuration to a single plugin within a bundle can be confusing with messy syntax, especially if the bundle doesn't do ConfigSlicer or something like that.
do
ConfigSlicer
And the effort of learning and using those tools is high if all you want to do is temporarily change a build setting for the point of local use or local testing.
So this command attempts to avoid these problems by separating the bundle from its configuration until configuration is wanted updated.
This means Dist::Zilla based distributions DON'T have their build configuration radically changed simply because somebody upgraded a bundle, and the configuration is MORE local to the distribution instead of being more global.
Dist::Zilla
This means bundle specific configuration demands ONLY need to be satisfied during the baking process, but NOT every subsequent build, and are thus NOT prone to causing a sea of unusable dist.inis if a bundle gets changed.
dist.ini
The biggest known downside of this approach at present is with much more advanced bundle usage.
Because the bundle itself is being taken out of the loop, that means dist.ini will NOT be able to automatically have new plugins added to it in response to changes in the tree. dzil bakeini will have to be run subsequently to take tree changes into consideration and emit updated configuration.
dzil bakeini
And because the bundle itself is being taken out of the loop, that means ENV based controls in bundles will be bound at the time of calling dzil bakeini, which means if you're like @ETHER and have an "Airplane mode", then:
ENV
@ETHER
AIRPLANE=1 dzil build
Won't work on a baked dist.ini, and you will instead need:
AIRPLANE=1 dzil bakeini && dzil build
Though, that could be beneficial too depending on how you use it.
# Get on the plane AIRPLANE=1 dzil bakeini # dzil runs everything in airplane mode now dzil build # Get off the plane dzil bakeini # dzil runs normally dzil build
bakeini
If you want to codify some unique behavior to how your bundle performs under dzil bakeini, ( for instance, to change the prereqs advertised as being develop.requires )
prereqs
develop.requires
Here, ::Util::CurrentCmd comes in handy:
::Util::CurrentCmd
use Dist::Zilla::Util::CurrentCmd qw(current_cmd); my @config; ... if ( 'bakeini' eq ( current_cmd() || '' ) ) { push @config, [ 'baked dist prereqs', 'Dist::Zilla::Plugin::Prereqs', { 'Foo::Bar' => 2 }]; } else { ... }
