   A fast json parser for go

   I wrote a mostly branchless json parser in go using ragel to generate most of the code.

   The code isn't much to look at, but it is certainly fast.

3. zig

   2 869 38,110 10.0 Zig

   General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

   

   Sad but true. This is why I'm hopeful that Zig will add support for "constant time" blocks: https://github.com/ziglang/zig/issues/1776

   Generate x86 Assembly with Go

   

   You could perhaps just have the Go compiler generate the assembler for your code:

   go tool compile -S file.go > file_amd64.s

   Then you could verify it doesn't change over time, and choose to begin maintaining by hand if it makes sense.

   If you do want to go the route of rolling it yourself, I'd suggest looking into something like Avo: https://github.com/mmcloughlin/avo
