This is mainly updates to the build system, but there were a couple of
stdlib changes for the tests. The build system does include handling
more properly now as well, I think. It has fewer hacks, at least.
I've gotten tired of trying to find this in the cache dir, since the
build system does not rerun it once it is cached. Also sometimes the
build runner does weird things to the output.
This was the point that I realized there's no reason to have the string
variants of the publishing methods. But also there's not really much
point in porting the other getting-started examples, since we've
covered all their functionality in the existing examples
(actually, this one is redundant too, but I have already done it, so
it's getting grandfathered in).
Porting some of the more interesting examples might be a good idea, but
those have a weird argument parser that I don't really want to port
(even though it is very simple in the way that it works). For the most
part, I think writing unit tests will do a better of flexing the
bindings.
I think I am probably going to move unit tests to a separate
directory/file structure. This will allow me to add a bunch of utility
functions that don't get analyzed for the library compilation and also
avoid testing-only imports in the main modules.
This builds a very basic version of the nats.c client (no TLS, no
streaming/jetstream/whatever, since those bring in complex
dependencies and I do not need them at the moment). Right now it
contains a simple test program that demonstrates the functionality
(cool!), but the plan is for the nats.zig to bind the API into a
nicer, zig-like shape and re-export it. Then this becomes a package.
The current function could become a test, though it's a bit complex
for a unit test (and requires connecting to an externally-running NATS
server in order to work).
