Re: [cdt-dev] DSF/CDI Launchers weirdness

[Doug Schaefer <cdtdoug@xxxxxxxxx>]

My hope is that when the user hits run, it never asks him for anything, it just runs a local application determined by the context of the selection and assuming the application can run locally, which we should also be able to determine. There should never be a question on what debugger integration to use for run because it doesn't matter.

I think the same should be true for Debug. We should be able to tell from the context of the selection what debugger to run. And that decides what integration to use, not the other way around. This is something I've stated before, and I still stand by it.

I just think we've hijacked launch configuration types for debugger integrations. There should be only be one for Local Applications, and the choice of debugger integration is further down the pipe. We should never put the choice of debugger integration into the face of the user. There's no way they can understand the choice.

The terminology always confuses me so I might have mis-understood
what you meant, but here goes:

We only have one launch configuration type for Run:
"C/C++ local application".
After you've chosen this launch config type, you have to
choose which debugger integration using the hyperlink at the
bottom of the launch tabs.

For Debug, it is not great but necessary.
But for Run?  Do we really need to have that extra step?
I say we have a single launch delegate when using Run.

Does it make sense?
