Implied and now executed tasks:

• downstream testing (so core would know it didn't break deps, etc)
• delegate tests down to living next to relevant code
• delegate demos down to living next to relevant code

[mohawk2]

The releasing of all the non-fundamental modules as independent CPAN modules has been completed. Remaining tasks now on #516.

[karlglazebrook]

It would be helpful to update the table at the top of an issue, what dates from 2015!

[mohawk2]

It reflected our thinking back then, but isn't entirely the direction taken. I don't know to whom that would be helpful, or how? ;-)

[karlglazebrook]

I would just like an easy to refer to list of what was taken out in the 'big split' and where it went :-)

[mohawk2]

The answer to any question of "what changed in PDL" is to look in the handy "Changes" file: https://github.com/PDLPorters/pdl/blob/master/Changes

[karlglazebrook]

A diary is different to a plan, but grepping Changes.txt for various terms is this the complete list? i.e. we are definitely done?

• move PDL::Graphics::State to PGPLOT distro
• split PDL::Graphics::Limits out to separate distro
• split PDL::IO::Browser out to separate distro
• split PDL::Perldl2 out to separate distro
• split PDL::Complex out to separate distro
• split PDL::IO::HDF out to separate distro
• split PDL::IO::GD out to separate distro
• split PDL::Transform::Proj4 out to separate distro
• split PDL::IO::IDL out to separate distro
• split PDL::IO::Dicom out to separate distro
• finish, then split PDL::IO::ENVI out to separate distro
• split PDL::Graphics::TriD out to separate distro
• split PDL::GSL out to separate distro
• split PDL::Slatec out to separate distro
• split PDL::Fit out to separate distro
• split PDL::Opt::Simplex out to separate distro
• split Graphics/IIS out to separate PDL::Graphics::IIS distro
• split Libtmp/Minuit out to separate PDL::Minuit distro
• move PDL::Graphics::LUT to PGPLOT distro

[karlglazebrook]

These all seem sensible to me except for pdl2, what is the logic there? Should we just replace pdl with pdl2 in distro?

[mohawk2]

Yes, that's the complete list.

pdl2 requires Moose, a very large external dependency (and slow to install, which slows down CI), and it is quite slow to start up, and cranky in its design. I've tried it and have always liked perldl a lot more, which benefits from a couple of extra modules, but works fine without them.

[karlglazebrook]

OK, I have never got into pdl2 hence my ignorance. But that makes sense,
