Purego – A library for calling C functions from Go without Cgo

   I thought I had a piece of dust on my screen, but as I scrolled the dust scrolled: what do these 0xB7 characters do in the identifiers? Are they just "name mangling" to keep them from being exported or something?

   I noticed another 0xB7 character in a comment, and sure enough it seems to be part of the identifiers: https://github.com/ebitengine/purego/search?q=runtime%C2%B7c...

   Very cool! I will definitely give this a try, I've been looking to build Go bindings to Mach[0] soon.

   How does this work around the stack size problem? IIRC the reason CGO overhead exists is at least partly because goroutines only have an ~8k stack to start with, and the C code doesn't know how to expand it-so CGO calls "must" first have the goroutine switched to an OS thread which has an ~8MB stack.

   One reason I think Go <-> Zig could be a fantastic pairing is that Zig plans to add a builtin which tells you the maximum stack size of a given function[1], so you could grow the goroutine stack to that size and then call Zig (or, since Zig an compile C code, you could also call C with a tiny shim to report the stack required?) and then eliminate the goroutine -> OS thread switching overhead.

4. bud

   3 34 5,598 4.3 JavaScript

   The Full-Stack Web Framework for Go

   

   Awesome!

   This would be such a game-changer for server-side rendering Javascript in Go with V8.

   I'd love to integrate this into Bud[1].

5. SWIG

   4 29 6,048 9.6 C++

   SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages.

   

   How is this any different than a mature tool such as SWIG (https://www.swig.org/)?

   I've used SWIG extensively with Python to call C code and import C headers for testing/tooling purposes.

6. rust-plus-golang

   Oh then sure, I don't see why you couldn't use it with something like https://github.com/mediremi/rust-plus-golang
