[isocpp-sg15] Free Browser-Based C++ Editor – Pterocos for Quick Prototyping & Tooling Experimentation

Hello SG15,

I've been developing a free, open-source tool called Pterocos (
https://pterocos.eu.org) that I believe aligns with this group's interest
in C++ tooling. It's a browser-based code editor that runs entirely
client-side via WebAssembly, requiring no installation or account.

Key features for tooling exploration and development:

Monaco Editor backend: Provides a familiar VS Code-like experience with
syntax highlighting and autocompletion.

Client-side compilation: Compiles and executes C++ code locally in the
browser, making it ideal for quick prototyping and testing.

AI assistant integration: Built-in debugging and code generation assistance.

No setup friction: Lowers the barrier for testing snippets, exploring
language features, or sharing reproducible examples.

>From a tooling perspective, I think it could be useful for:

Rapidly experimenting with compiler flags and standard library
implementations.

Creating portable, shareable code demonstrations for documentation or bug
reports.

Lowering the entry barrier for new developers to experiment with C++.

The project is open-source, and I'm actively seeking feedback to improve
it, especially regarding compiler support, standard library conformance,
and integration with other C++ tools.

I'd be very interested in your thoughts and any suggestions that could make
this more valuable to the C++ developer community.

Best regards,
AmineKHD
