I built one of the tools mentioned in the article, Deno's linter. Its binary is over 30 MiB:

After a long time, I started contributing to open-source software. For a long time, I had my eye on Deno. This week, I merged my first PR in Deno Lint. Following is the detailed post about the issue.

I read your latest post about linters and not liking ceremony involved in setting up eslint. Have you tried deno lint by any chance?

You can use it via the deno binary as well.

Yes, it's https://github.com/llvm/llvm-project/issues/54744

The canonical build system for LLVM is CMake, but you can also build LLVM with Bazel now. That might give you a good idea of how to do it. The Bazel support code is in https://github.com/llvm/llvm-project/tree/main/utils/bazel

The point was to compare the size of Zig to Clangs. Check out the downloads here: https://github.com/llvm/llvm-project/releases/tag/llvmorg-14.0.5. The Clang toolchains are around 500 MB, and I believe these are native toolchains that don't support cross-compilation, so you would have to download N of them for every N targets you'd like to compile to. Also even if you download these, if you want to do all the stuff that Zig can do you're also going to need to download other things like Musl and Xcode and MSVC, etc.

It's time to tell a little bit about Rust. It has a lot in common with C++. It is built on llvm (C++ compiler toolkit), it does not have a garbage collector, and it also does not support reflection. But nevertheless, he has a very cool serde, which is not inferior to solutions from other languages.

The Clang Static Analyzer is a great codebase to learn from. A long time ago, before Z3 was open source, I added a constraint manager that used STP for the same objective: https://reviews.llvm.org/D15609

It may be dated by now but there is also a tutorial on writing checkers (https://clang-analyzer.llvm.org/checker_dev_manual.html), or follow one of the many examples in the codebase.

My first checker is still there — it just turned 10 years old, and is under 100 lines without comments. https://github.com/llvm/llvm-project/blob/main/clang/lib/Sta...

And https://github.com/llvm/llvm-project/tree/main/libcxx for Clang's libc++

I would be interested to see how good is https://github.com/llvm/llvm-project/blob/main/llvm/include/llvm/ADT/DenseMap.h
