relates to:

  • SR-1303 [SwiftPM] Support for showing "Swift generated interface"

Issue Description:

Currently, swift-ide-test or the -deprecated-integrated-repl can be used to print out a Swift module's interface (https://gist.github.com/natecook1000/ce6631a23649dc952d8e).

It would be nice if this functionality were available to anyone, just by running swift with a special flag such as -print-module-interface.

Removing the StarterBug tag because I'm not convinced this is the right interface for this functionality. The simple version is making swift-ide-test's interface better at it. The full REPL can also print both modules and decls with :type lookup.

That's cool, I didn't know about :type lookup.

Is this still an idea either of you are interested in pursuing, or is :type lookup sufficient?

From a usability (and scriptability) perspective, I still think it would be nice for this to be a separate driver option and not something that requires the REPL. However, I'm not actively pursuing it, and if others disagree I'm not strongly opposed to closing the issue. But I suspect it would be a good StarterBug if someone were interested.

Comment by Dave Yost (JIRA)

I think a swift interface source file should be created whenever you build a system-module package. The disk space required is not such a big thing compared to the usability benefit. There could be a flag on swift build to suppress the building of such nonessentials.
