Re: Autobundling the installer

I think the other big one is that authors are often hesitant to take advantage of new M::B features, or to make an M::B-only distribution, because it can add extra burdens to their users. True, though configure_requires should solve that once the cpan client is upgraded, right? Some users (eg. non-root newbies) have difficulty doing that. When a user only cares about using your particular module (which basically just needs to be put somewhere in PERL5LIB), requiring them to upgrade CPAN/ install M::B is a serious pain for them. For one real-world example: http://bioperl.org/pipermail/bioperl-l/2007-August/026230.html
Re: Command-line options available during actions?
Salve J Nilsen wrote: Sendu Bala wrote: Can anyone suggest a solution that could be implemented in an M::B subclass to make --something visible in a test script when running the test action? I've tried looking through the M::B code but the command-line arg handling is just way too obfuscated for me to figure out where to 'patch into' the system, so to speak. My might want to look at the get_options(), notes() and current() methods documented in Module::Build::API. Specifically, how do those help me? I'm already using those to store --something if --something is supplied to Build.PL: perl Build.PL --something ... ./Build test --test_files t/test.t test.t knows about --something via notes(). I want to pass --something directly during test, however, to specify or negate what ever the current notes value may be.
Re: Bad interaction between custom build module and new CPAN.pm
Andreas J. Koenig wrote: CPAN.pm still has an open issue with Module::Build with regard to finding out the prerequisites of a distribution. I append the email below where I asked the encompassing question: can I rely on the contents of _build/prereqs? Since then I have changed CPAN.pm in 1.88_63 to actually read _build/prereqs. All CPAN seems to be conquered with this trick. All of CPAN? Actually, one developer complained about it: Sendu Bala (CC'd) who released SENDU/bioperl-1.5.2_100.tar.gz in December. He used some heavy Module::Build subclassing wizardry, I did not try to understand it. Specifically the issue was that my _build/prereqs 'requires' wasn't the normal dumped hash-ref, but an array of hash-refs (such that CPAN/my M::B subclass would install things in a certain order). But after discussion with Andreas I find that order can be achieved a better way, so I could do an updated release that behaves normally wrt _build/prereqs. Andreas, when were you thinking of releasing 1.89? I'd like just a little time to update bioperl before hand. Would it be possible to make an interface decision for the prereqs? All that said, I still have to point out my issues with this approach. The '_build' directory is supposed to be configurable. The prereqs file is a dump of the internal data structure of a module. It seems extremely wrong to me for CPAN to have to hard-code the location of this file and assume the format of its contents. This is no suitable 'interface'! There ought to be some defined M::B method that generates a file that CPAN will read, thus allowing the format and location of the file to be documented in the API, and allowing M::B sub-classers to massage their data correctly in their over-ridden version of that method. (I'm still not really clear on the problem with CPAN using $req = Module::Build-current-requires();. Seems 'correct' and ideal to me.)
Module::Build install doesn't use its own Build.PL
During Module::Build installation, it fails to use its own Build.PL if another is in perl5lib, resulting in test failures. With Mac OS X I downloaded perl-5.8.8 and did a clean install: cd ~/Desktop/ tar -xzf perl-5.8.8.tgz cd perl-5.8.8 sh Configure -Dprefix=/test/perl -Dcc=gcc -des make make test sudo rm -rf /test sudo mkdir /test sudo make install sudo rm -rf ~/.cpan setenv PATH /test/perl/bin:$PATH Now I check my perl5lib: perl -V Summary of my perl5 (revision 5 version 8 subversion 8) configuration: Platform: osname=darwin, osvers=8.8.1, archname=darwin-2level uname='darwin dhn02982.mrc-dunn.cam.ac.uk 8.8.1 darwin kernel version 8.8.1: mon sep 25 19:42:00 pdt 2006; root:xnu-792.13.8.obj~1release_i386 i386 i386 ' config_args='-Dprefix=/test/perl -Dcc=gcc -des' [...] %ENV: PERL5LIB=/sw/lib/perl5:/sw/lib/perl5/darwin:/Users/sb/Work/scripts:/Volumes/biodav/core:/Volumes/biodav/run @INC: /sw/lib/perl5 /sw/lib/perl5/darwin /Users/sb/Work/scripts /Volumes/biodav/core /Volumes/biodav/run /test/perl/lib/5.8.8/darwin-2level /test/perl/lib/5.8.8 /test/perl/lib/site_perl/5.8.8/darwin-2level /test/perl/lib/site_perl/5.8.8 /test/perl/lib/site_perl .

optional_features possible?
I currently have a setup like:
my $build = Module::Build-new(
#...
recommends = {'Module' = 0}
)
I can then use ./Build distmeta to generate a META.yml file with content
like:
requires:
Module: 0
Is it possible to get Module::Build to generate the optional_features
syntax instead? So I want:
optional_features:
- foo:
description: Provides the ability to blah.
requires:
Module: 0
Also, where can I find full documentation for all of the methods
available? Eg. I couldn't find anything that even told me all the
possible options you can supply to Module::Build-new(), having looked
in these places:
http://search.cpan.org/~kwilliams/Module-Build-0.2805/lib/Module/Build.pm
http://search.cpan.org/~kwilliams/Module-Build-0.2805/lib/Module/Build/Authoring.pod
http://search.cpan.org/~kwilliams/Module-Build-0.2805/lib/Module/Build/Cookbook.pm
http://search.cpan.org/~kwilliams/Module-Build-0.2805/lib/Module/Build/Compat.pm
So far I've just looked through the code of Module/Build/Base.pm to
guess what I should be able to do, which isn't ideal.
