bootstrap-seeds VS zls

This[0] is basically the hand-documentation of those bytes then. Handwritten ELF header and assembly code.

The bootstrap seed, https://github.com/oriansj/bootstrap-seeds/blob/master/POSIX..., is a tiny interpreter that takes a much larger program written in a special-purpose, bytecode-based language. This proceeds in turn once or twice more--special purpose program generating another interpreter for another special-purpose language--until you end up with a minimal Scheme interpreter, which then can be used to execute a C compiler program.

All of this is incredible work, but a minimal C-subset compiler in under 512 bytes seems like a unique achievement.

There is also live-bootstrap which uses a similar bootstrap chain to Guix (stage0 -> Mes -> tcc -> gcc), but without needing Guile/guix-daemon binaries etc. The whole thing starts with just a 357-byte binary seed (source)!

Yeah, it's a binary blob, but it's small enough to be easily auditable. Anyone with some knowledge of x86 assembly can read the annotated version [1] and verify that it does what it claims (which is to convert ASCII hex with comments into binary).

You're right, it also requires a Linux kernel, and of course, you also have to trust the hardware you're running it on. Still, it reduces the amount of stuff we have to take for granted as trusted, which I think is a good thing. (I'm not involved in the project, just an admirer).

stage0-posix just gained initial support for RISC-V (64-bit). It starts with 392 byte hex assembler, 361 byte "shell" and bootstraps simple linker (hex2), macro assembler (M0). Then it builds cc_riscv64 RISC-V compiler written in RISC-V assembly and uses it to build simple C compiler written in C (M2-Planet). Then it builds a few extra utilities (cp, mkdir, untar, ungz, sha256sum, chmod)

From a security point of view the only thing that gentoo users need to achieve similar levels of security is a bootstrapped compiler from a known good seed. The source code is already deterministic by definition. After that all you need is a compiler bootstrapped via something like https://github.com/oriansj/bootstrap-seeds which can be independently verified. It would probably be useful to be able to have independent bootstraps arrive at the same binary output for a compiler, but probably only as an option. Ultimately way less work for the same level of security.

There is no official documentation but the standard library provides definitions for the exchange format and an incomplete set of function for exchanging messages in Client.zig and Server.zig. You can find examples of the zig compile server in action in my PR for ZLS and a showcase of hot-code-swapping by kubkon. The code that implements the ZCS in the zig codebase can be found here.

Same experience here, I did file a bug about it too: https://github.com/zigtools/zls/issues/1139

Welcome to the word of new languages, I think rust just got an intellij plugin late last year and its been in 1.0 since 2015 (not to mention the years of hype around it). When it comes to "non standard" languages (meaning not the industries current go to for a given niche), it helps to assume there's no "It's just works" type editor support. Luckily most languages, even new ones have LSP servers including zig, and editors like VSCode make it pretty simple to use them.

For the people who come in the future and want to know how to do it, here is the code as of today (at some point it will be in ZLS repository - github.com/zigtools/zls - and you should take a look there too to see more up-to-date code).

Commands: git clone --recurse-submodules https://github.com/zigtools/zls cd zls zig build -Drelease-safe

> Building is slow. It takes about ~3 seconds minimum which is frustratingly slow when I'm fighting basic syntax errors. I wish there was a fast zig check.

> Lack of zig-analyzer makes learning hard.

> zig fmt src/main.zig is nice. Wish it automatically ran on all files.

I also did (well, "am doing", can only work a bit each day and am plugging through day 7 right now) AdventOfCode in Zig this year.

These points here didn't resonate with me at all. I wonder if the author knew about or tried ZLS[0]. I had it on and integrated with my VSCode and it would check a lot of things as I went and format on save. I think I followed something like this[1] to set it up.
