The Second Great Simplification of Til

I want Til to be again “easy to embed” in any C program so that I can make good use of any “big lib” without relying on thousand-lines kind-of-abandoned wrappers written in D.

By “big lib” I mean, for now, Tk. I really want to have a til-tcl and til-tk soon, but my only hope of doing that is using D’s importC.

gRPC is another interesting use case I may be using in the future: it would be lovely to be able to use Til to facilitate my life, but gRPC has its “languages of choice” and implementing it on a new one, like D, means a lot of effort and a lot of time of maturing for the new libraries to be production-ready. So I can cut some corners by embedding a Til program inside a C/C++ one for now.

So I eliminated the async part of Til, specially after I realized that, curiously, it could be implemented easily as a library: the basis of that is a AsyncPipeline class inheriting from til.nodes.pipeline.Pipeline that yields after the end of super().run. And the old commands, like spawn and all the Pid methods.

Queues are gone, too. I’m publishing that as a separate package, because anyone could implement such a thing using a SimpleList using Til itself, so I deemed it as “not atomic enough” to be native to the language.

These two main changes simplified the language a lot and now it became an easier task to create some C bindings. I’m planning to publish a Tcl library to run Til code very soon!
