What forth implementation could be a good pick for writing a texteditor?
I don't know the status of gforth's 'minos2' offering but I see a mention of X11 which is a promising sight for Linux GUI work.

Aro: A C compiler written in Zig
For contrast, gforth (a prominent Forth interpreter, by Forth standards) generates+compiles+links binding code in C, at runtime, using the ordinary C toolchain. [0][1][2]
A bit 'out there' you may say, but on the plus side this approach enables handling header files and tidily expressing bindings without the need to implement their own C parser. [2]

which forth do you guys use for normal day to day scripting and programming
I use SP-Forth (production), Gforth (testing).

no more bit fiddling (and introducing bilge)
Possible reference as it requires to use the compiler as part of language abi: https://github.com/Vexu/arocc/issues/178 Not sure, where a better thread with explanations of the flaws is.

Zig Build System
Zig calls clang to compile C code. This doesn't add a new dependency since Zig already depends on LLVM. In the future when Zig doesn't depend as much on LLVM, there might be a reason to use a C compiler written in Zig (e.g. https://github.com/Vexu/arocc)

Zig 0.9.0
> Does this mean that y'all are open to the self-hosted compiler supporting CPU architectures unlikely to ever have LLVM support?
Yes! We won't block 1.0 on the quality of the less mainstream targets, but that's what the tier system is for - to ship a compiler that has varying levels of quality for various targets, while communicating clearly to users what kind of experience they can expect for each one.
SuperH patches are absolutely welcome.
> how is zig cc anticipated to work with a self-hosted Zig? Will there be a dependency on clang [...]?
The main distribution of Zig will be LLVM/Clang-enabled. However it is already possible to build a version of Zig that does not have these features enabled. In such case, compiling C, C++, and Objective-C code will result in an error.
However, the arocc project[1] is emerging, which, depending on a combination of how much funding ZSF gets and how much enthusiasm the unpaid contributors working in their spare time have, is looking like a promising C frontend that would be available even without LLVM/Clang. It is C only, however, with no intention of compiling C++ or Objective-C.
> would zig cc support the planned C backend?
As it is currently implemented: no. Zig invokes clang to turn C source code into object files.
However, with the arocc frontend above, this would be converting the C source code into ZIR (or perhaps AIR), which could then be lowered with any of the backends, including the (partially complete) C backend. In such case, the C output would look drastically different than the input. It would look more like an IR than natural C code that a human would write.

[Rust advocates] demean software that's not memory safe the way that politicians use their words to sow anger. C has won, and Rust blew it's shot aiming at C++ instead.
Implementing only the language part takes like 10k LOC.

Adding ANSI C11 C compiler to D so it can import and compile C files directly

This is a really insightful point. I had to learn this the hard way :)
We might follow your lead on this, as we have done with so many other great ideas implemented in D.
Ironically, Vexu started from the other side as you, with the preprocessor mostly done, but the backend left to-do: https://github.com/Vexu/arocc
One thing that might make libclang worth the cost, however, is its ability to compile C++ code as well. On Zig's end of things, all we have to do is provide libcxx, libcxxabi, libunwind, compiler-rt, and linking, and then libclang is really pulling a lot of weight by compiling C++ code into object files. Sadly this ability is just too useful in practice to ignore. For example, LLVM itself is C++ so if Zig wants to be able to bootstrap itself, it needs this capability.
Still, I think your maneuver here is the best long-term approach to tackle this problem, and I imagine as time goes on we'll start to migrate towards D's solution here. Maybe someday the Zig distribution that does not have LLVM extensions enabled will be the more popular one!
I'll be watching the evolution of this new feature in D with great interest!
