Alan Donovan e8afbfad8c go.tools/importer: API rethink. ... The Importer type has been replaced with Config and Program. Clients populate a Config, directly or more usually via convenience functions. They then call its Load() method to do all of the typechecking and transitive-closure computation. ssa.NewProgram and ssa.CreatePackages have been fused into ssa.Create, which now cannot fail, since (*Config).Load() reports all type errors. Also: - The addition of an ssa.GlobalDebug builder mode flag eliminates a loop-over-packages repeated in many clients. - PackageInfo.Err flag unexported. Clients never see bad infos now. - cmd/ssadump: now only looks for func "main" in package "main". - importsOf deleted, was dead code. STILL TODO: - ParseFile seems like API creep (though it's convenient) and CreateFromFiles is dangerous (w.r.t. FileSet identity). Need to think more... - the need for clients to rely on elementwise correspondence of Config.CreatePkgs and Program.Created is a little sad. - The command-line interface has not changed. That will happen in a follow-up. r recommends using a repeated flag: -package p -package q ...
