Cpi is a tiny C++ interpreter that allows users to compile and execute C++ programs immediately like a scripting language. It uses an internal compiler to interpret code without requiring separate compilation steps.… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Cpi – Immediately compile and execute c++ program like a scripting lang launched in 2017; newer entries below may have overtaken it.

   CJIT▲83

   CJIT started as a hobby project around Fabrice Bellard’s tinyCC and slowly grew into something much more practical. It is now a small portable C compiler and runner that works across Linux, macOS, and Windows, can self host, and is packaged as a single executable. What mattered most to me was keeping the barrier to entry low. You can take one small binary, drop it onto a system, and compile or run C code using the libraries already available there, without setting up a full toolchain or installing a large stack of dependencies. I find that useful for quick prototyping, testing, auditing,…

    I built a Cargo-like build tool for C/C++▲177

    I love C and C++, but setting up projects can sometimes be a pain. Every time I wanted to start something new I'd spend the first hour writing CMakeLists.txt, figuring out find_package, copying boilerplate from my last project, and googling why my library isn't linking. By the time the project was actually set up I'd lost all momentum. So, I built Craft - a lightweight build and workflow tool for C and C++. Instead of writing CMake, your project configuration goes in a simple craft.toml: [project] name = "my_app" version = "0.1.0" language = "c" c_standard = 99 [build] type = "executable"…

    C++ Compiler Support Page▲68

    Hi HN, I have created a webpage that displays all C++ features since C++20 in a simple, searchable table. It is intended to serve as a quick reference for C++ developers, whether as support for cross-platform development or simply to track the current support status out of curiosity. I created it as a simpler, more structured, and more up-to-date alternative to the cppreference compiler support site. Please note that the page intentionally does not list LWG and CWG papers. This might change as I am continually updating the site and trying out new ideas. Questions, feedback and suggestions…

    A Lisp Interpreter for Shell Scripting▲114

    Redstart is a lightweight Lisp interpreter written in C++ with a focus on shell scripting. It lets you combine the expressive power of Lisp with the practicality of the Unix shell: you can run commands, capture output, pipe between processes, and still use Lisp syntax for logic and structure. Think of it as writing your shell scripts in Lisp instead of Bash.
