Hi,
Attached are two proposed patches related to compatibility for EIEIO and
EDE.
The EIEIO patch helps with loading old EDE save files. It updates
existing compatibility for the 1st object name argument to constructor
during object loading from a file. In older versions of EIEIO, objects
were saved with a 'name'. New EIEIO skips the name on load. This patch
will apply the name to the :object-name slot if it is a subclass of
eieio-named. This will compatibly bring in old objects and maintain the
name.
I tried it with the existing eieio tests which passed.
The EDE patch brings over a change from the CEDET repository on Source
Forge that enables project types detected via a function. The function
based project types were never integrated into Emacs. This patch allows
these old project types from SourceForge to work with built-in EDE.
There are no uses of this feature in Emacs, but it is useful for
integrating new project types that are not easily identified by a
string, such as android, arduino, fitbit and other tools that usually
provide their own 'studio' thing.
The EDE patch was written by me before the last 'release' I had signed
from my company. The EIEIO patch is new.
Thanks
Eric

Attached is one more small patch I had missed in my previous set. This
change is independent of the other two. This is also needed to load
Project.ede files that happen to include custom rules, where those rules
are also objects. The Project loader's error checking in eieio-base.el
requires the :type to be precise when the value can be a list of objects.
I used the same basic mechanism used in ede/base.el for ede-project's
'targets' slot.
If you want to verify the changes, this project uses the feature:
https://sourceforge.net/p/matlab-emacs/src/ci/master/tree/
Use global-ede-mode and visit this project.
Thanks

I don't understand the (fboundp 'ede-makefile-rule-p) test, maybe it
deserves a comment?

How 'bout using
:type (list-of ede-makefile-rule)
?

Thanks for looking at my patch,
The short answer to your questions is that I'm not very familiar with
how the typing system works with the latest eieio changes. I'm fine
with the proposed use of (list-of ...) as it seems much simpler and more
obvious.
I would expect you would want to make the same change in ede/base.el
around line 172, which is the code I used as a template to make :rules
work. Maybe something like the below patch?
I suspect the fboundp part was transitional when the old auto-generated
predicates were deprecated. Maybe useful in an external bit of elisp
that needs to support multiple versions, but not here. Thanks for
pointing this out.

I suspect we're the two most knowledgeable about it, so if you have
a doubt about one part I hope I can help.

OK, I've changed the code to use that.

Looks good to me.
