&cuik started work on the user-friendly diagnostics option 🎉 , the idea being that some reporting methods play better with automated systems like editors but some play far better at removing the noise (there's both a highlighted options and caret version because colors aren't always available and i haven't decided on things yet). Compare this against the old way of dealing with these types of errors.

warning: unfinished
The plan is a modern C11 compiler which can mostly work with Clang, GCC, and MSVC while also introducing some new ideas.
Why write a C compiler?
- To improve the compile times on debug builds without sacrificing features like I would with TCC.
- To test out my upcoming (and currently private) compiler backend.
- To add some extensions to improve the workflow of C programmers.
- Because I can.
How am I doing?
mostly aight, thanks for asking.
What are some cool new things?
One of my favorite new features are the live compiler (essentially an offline Godbolt but within a terminal) and the out of order declarations.
What architectures will you support?
I'll be starting with x64 but I plan on having Aarch64 support soon enough, it's mostly a matter of user-demand what other platforms I add though I probably won't be supporting anything with a segmented address space because I don't want to implement it.
What OSes will you support?
Ideally the essentials like Windows, Linux and MacOS but currently MacOS isn't setup and Linux has basic support (no live compiler)
Will it have optimizations?
It will eventually have a smart but non-aggressive optimizer but that's still a work in progress
What C extensions will you have?
I'll be supporting all the normal extensions such as:
- pragma once
- builtin bitmath (popcount, ffs, clz, ctz, etc)
- __builtin_trap, __builtin_expect
- x86 SIMD intrinsics
- typeof
- case ranges
- computed goto
And some possibly novel extensions such as:
- Out of order functions
- Tagged unions
What's left?
It can currently compile programs using the subset of C it currently supports but it's still missing some essential details before it compiles any basic C program such as:
- More tests
- Bug fixes
- Self hosting
- Thread local
- Atomics (halfway there)
- MSVC extensions
- GNU extensions
- Proper Mac/Linux support
Sauce?

&cuik Guess who just got a little further into Codeview support in Cuik/TB! 🎉
&cuik Been making changes to the CLI, also the spinning triangle is doing as spinning triangles do... that's right, compile correctly
Getting closer to having parsed & type checked my entire compiler with itself 🥳, ignore the .cpp file, it won't be doing that one, instead i'll probably convert it to valid C file &cuik
