[lldb-dev] Get source-map from python API?

[Jim Ingham via lldb-dev]

If you mean "Add an API that sets the source-map for a target" say to SBTarget, then that sounds great.  

But if we're going to add an API to get at settings in general, then we should talk about it more broadly before anybody gets started.  There was a bunch of stuff that we wanted to do with settings that we never got around to, but still want to do.  In particular, we had intended some as yet unspecified syntax for restricting settings to particular scenarios.  Not this, but something like:

settings set target[OS=OSX].expr-prefix my_osx_prefix.h

gives you an idea of what we had in mind.  I'd rather not add a full on API for the settings till we decide either how we want to do this (which I think would be worth the effort but I don't think any of us have got time to address this right now) or to scrap it and go with flat settings.

However, I could not find a python API to specify the source remapping, and more important a way to access the remapping functionality. The SBSourceManager class only exposes a single DisplaySourceLinesWithLineNumbers() method which displays the source in console output. Ideally it should expose an API in SBSourceManager for us to provide the old FileSpec and get back a new remapped FileSpec.
