[swift-lldb-dev] REPL questions

[Gage Morgan]

That was what I was looking for. Just one more question: For any project, how is a C to Swift function binding created? I'd like to know how to import C functions to Swift. Once I can do this successfully, I'll be all set.

Hi Gage,

The REPL does let you import Swift modules.  If you wanted to make or find
a GTK binding, load it into the REPL, and drive that via the REPL, you
certainly could do that.  Using the REPL to do this would allow you to
explore the binding at runtime, as many REPL-based languages afford.  Is
that the kind of thing you're after?

The last comment makes me think you may be asking more about a graphical
REPL, though.  Xcode has Playgrounds, but that doesn't exist in Open Source
Swift.  I don't see what would stop somebody from trying to write something
similar against GTK or any other GUI library.

Hope that helps!
