Compile and execute C++ in browser
2 projects | /r/cpp | 21 Jan 2023

Using Firecracker and Go to run short-lived, untrusted code execution jobs

Here are some more ports of LLVM and clang to the browser:
* https://github.com/kripken/llvm-js
* https://github.com/tbfleming/cib
* https://github.com/jprendes/emception
LLVM just does pure computation, really, so it's not hard to port to wasm - much simple than say Python (which has also been ported several times). The only challenges with LLVM are the build system (which has self-execution), working around some issues like clang wanting to open a subprocess, and adding some ifdefs.
Show HN: How to compile C/C++ for WASM, pure Clang, no libs, no framework

That is half of what I would need for a project, the other half being Clang itself running in the browser (to use for teaching), in theory there is [1] since many years, but in practice it never worked for me (even now I get "Runtime error: memory access out of bounds")

Do any Browser Based C Static Code Analysis Tools Exist?

It seems that there's a project doing exactly that: https://github.com/tbfleming/cib
Rust programming concepts for JavaScript developers
3 projects | news.ycombinator.com | 22 Nov 2021

It takes some work (mostly due to LLVM building code to run later in its build system as it goes), but it's very feasible. LLVM has been ported to Wasm (and before that to JS) many times, for example:
https://github.com/jprendes/emception (2021)
https://github.com/tbfleming/cib (2017)
https://github.com/kripken/llvm.js (2012)
I agree it would be great to see this repl running 100% in the browser!

Is that possible to use a Nim compiler in the browser?
2 projects | /r/nim | 18 May 2022

I have just stumbled upon this project which does exactly that - compiles C/C++ to WASM right in the browser. The included demo wouldn't load on my machine for some reason though. But it is the exact scenario I have thought of, running your whole 'IDE' in the browser, while serving the page's files simply with a GitHub page.
