Though, IMO focusing on C++ only is fine ATM.
As far as this goes, since exception configuration would be team-wide, it
seems the ideal approach would be to enumerate the languages used in the
current team in order to find all possible languages that might need
exception settings. Correspondingly, SourceLanguage would need to be
extended to add the following capabilities:
- indicate if the language in question supports exceptions and/or
configuring them at all.
- generate a language-specific exception settings configuration view.
- provide functions that handle the corresponding exception breakpoint
installation/removal.
- exception settings persistence/restoration.
However, currently we only store references to the source languages on the
source files that the functions reference, which is a bit unwieldy for
quickly finding them all. My initial thought is to also keep a list of
references on TeamDebugInfo itself in order to conveniently be able to
discover/enumerate them quickly for purposes like the above, and anything
else that might later need to access a particular language such as
expression evaluation, though the latter's more likely to be in the
context of a particular stack frame/function so that would implicitly know
the correct language anyways I suppose.
As a starting point so we'll have something to work with initially, I have
a simpler configuration window that just handles the C++ case for now, but
the above pretty much outlines the direction I envision going to handle it
properly in the long term. Feedback/design improvements would be
appreciated.
