tcl VS metal-cpp

Behold, a 16MB "Go" file: https://gitlab.com/cznic/tcl/-/blob/master/lib/tcl_windows_amd64.go

Based upon info in an AUTHORS file [0] for a different project by the user cznic, I think there is indeed some kind of connection with nic.cz

But I believe, based upon my membership on the GoNuts group / mailing list, that this is mostly the work of one individual, Jan Mercl (he is quite active in GoNuts) — as also stated in the previously mentioned AUTHORS file, and in the AUTHORS file for the port of Tcl that is the subject of the OP [1].

I have used some of his non-transpiled code/projects in my own Go projects in the past. He seems to be a very solid coder, often happy to share his views in GoNuts, and also frequently reviews others' code too.

I think the author of modernc.org/sqlite also ported the test suite. They wrote https://gitlab.com/cznic/tcl to run the TCL-based tests, for example.

My understanding is the proliferation of “XYZ-cpp” AI frameworks is due to the c++ support in Apple’s gpu library ‘Metal’, and the popularity of apple silicon for inference (and there are a few technical reasons for this): https://developer.apple.com/metal/cpp/

This is basically also what the "official" C++ API for Metal does (https://developer.apple.com/metal/cpp/), it's an automatically generated bindings wrapper which calls into ObjC runtime functions.

I also dabbled a bit with this idea by parsing clang AST-dumps of macOS system headers:

Unfortunately this is very brittle, and also broke on ARM CPUs, I guess the shim code needs some ABI adjustments (famously, objc_msgSend has multiple "ABI shapes": https://www.mikeash.com/pyblog/objc_msgsends-new-prototype.h...).

There's official C++-interface: https://developer.apple.com/metal/cpp/

It doesn't matter if the project driven by Microsoft or not, the cat (of automatically generated language bindings) is out of the bag. E.g. Zig is using the same approach without being an official MS project: https://github.com/marlersoft/zigwin32, and Apple has an automatically generated C++ API for Metal (https://developer.apple.com/metal/cpp/).

In the future, the question won't be "what language do I need to learn to code on this platform", but instead "are there language bindings for my favourite language".

this? https://developer.apple.com/metal/cpp/

Doesn't it just use objc/runtime.h and if anything is missing you can just add your custom api calls?

Metal has C++ bindings (which cover a full app lifecycle so you don’t have to touch Objective-C/Swift at all) but they’re based on the Objective-C memory model. There are some helper structs mimicking shared pointers, but you’ll still need to understand the basics of how an autorelease pool is used to avoid memory leaks and/or bad access crashes.
