Re: [Catalyst] use base vs use parent
ccing in -dev, as this is relevant there, and and contains a brain
dump :_)

Yep.

I did mangle trunk to show it as inheriting recently.

Yes, lots of places (and the helpers) haven't been updated yet.

This work is underway (helpers haven't been done as I for one haven't
wanted to work on the horrible crap that exists at the moment until
the GSOC project is a bit more finished, and makes it less horrible)!

<cough> yes, also fixed in trunk of the manual.

New -Manual release is waiting on some more fixes, which I'll try to
get to in the next week or two.

Note that the tutorial being updated will wait until it can match what
the helpers generate, without needing a 'and now we port to Moose'
section...

use base and use parent are both still fully supported, including
weird franken-combinations of 5.80 => use base => use Moose type
inheritance..

It was originally by design.

However the application class being @ISA ::Controller is bad, wrong
and deprecated, and removing it wholesale is a prerequisite for the
app/ctx split. Catalyst spitting out warnings when you have actions in
your MyApp.pm class (and therefore need it to be @ISA Controller) will
be appearing presently. (I.e. the code is present and commented out
until the tests are fixed - which is happening right now in a branch) :)

You _can_ have action methods in your root MyApp.pm, but as noted
above this a baaad and the scaffold has generated by
a ::Controller::Root which configures itself into the root namespace
for several years..

Cheers
