Re: [cdt-dev] A Builder Proposition


One of the things we are looking at here at Red Hat is a development RPM
plug-in, that would merge in with some of the stuff you are proposing.
One of the aims for this plugin would be to be able to import SRPMs and
output RPMs as part of the build process, and to modify the build
process as it currently exists to fit this requirement. I then saw your
mail, and though neat, someone else is exploring the build area and how
it can be built upon, and possibly improved. In conjunction with your
discussion, I'll dip my toes in the water and expound on some points.
Hopefully this will get the ball rolling! 

Regarding your proposal, what are currently looking at, and would
probably have implications on:

>Passing Info from the UI to the builder:

Probably the quite a bit of work here, in the application of a spec file
editing and maintenace. Possiblity an extension to the editor to assist
spec file editing (syntax highlighting, etc).

All again would be context sensitive to what we are looking at. It
raises some interesting question, especially the differing architecure

I won't comment on the the CBuilder class layout yet as I am still
exploring that. However it looks like a pretty cool design. I especially
like the proxy method as explained. I just wanted to drop a quick like
to register our interest.
