Quick update: getting bleadperl ready for META.json

By dagolden | Published: January 4, 2011

The latest development releases of Parse::CPAN::Meta now support both META.yml and META.json files. By default, it uses JSON::PP for the META.json files. Accordingly, JSON::PP has just been added to the Perl core. (Thank you to Makamaka for his work getting JSON::PP ready for bleadperl.) There's more work on the horizon, but I expect to get [...]

By dagolden | Published: November 10, 2010

One of my goals for Perl 5.14 that I've discussed with Jesse Vincent and Andreas Koenig is getting CPAN.pm to be able to bootstrap itself in a fresh perl installation without relying on external command line tools or FTP. LWP is too big a distribution to bundle into the core, but HTTP::Lite is a focused [...]
