Reinventing Build.PL
Leon Timmermans
August 15th 2011
Once upon a time
- MakeMaker
- Perl -> Makefile -> shell -> Perl
- Module::Build
Module::Build
- 6000 LOC and 342 methods in one class
- BTW, it's lacking a maintainer…
Finding the way out
- configure_requirements
- Build.PL spec (draft)
The experiment
- Module::Build::Tiny
- Simplest thing that's useful and correct
- Currently only 65 lines
- «we stop being fucking idiots and use CPAN»
4 steps
perl Build.PL
./Build
./Build test
./Build install
perl Build.PL
- Write a Build script
- Save its arguments somewhere
- Write a MYMETA.{json,yml} (new)
./Build
- Real meat of any module builder
- Also the least specified
./Build test
- Run tests and summarise the results
- TAP::Parser does this for you and more
./Build install
- Install files in the right locations.
- I extracted ExtUtils::InstallPaths from Module::Build for this.
Authoring?
- Dist::Zilla plugin
- Only 25 lines (no golfing)
Take home message
- Writing a module builder isn't that hard anymore in 2011
These binaries (installable software) and packages are in development.
