history

Project history and usage

cpi is a small C++ interpreter-style command-line tool from the TreeFrog Framework organization. Its upstream description and README present it as a tiny interpreter for C++20 or C++23 rather than as a separate language implementation.

Project history

The public GitHub repository was created in December 2012. The README documents a design that uses an installed C++ compiler internally, with Qt 6 and a C++ compiler as build/runtime requirements, so the package sits between a REPL, a script runner, and a thin compile-and-run wrapper.

Adoption history

Package-manager adoption appears niche: the supplied package facts list Homebrew and MacPorts. That is consistent with cpi's role as a developer convenience tool rather than a core language runtime.

How it is used

The README shows interactive mode, execution of saved C++ source files, per-file compile options, pkg-config integration, and Qt examples. For package users, the important behavior is that cpi depends on the host compiler toolchain rather than shipping an independent C++ execution engine.

Why package nerds care

cpi is interesting to packagers because it exposes C++ as something close to a scripting workflow while still needing normal C++ and Qt build dependencies. Its documented per-user INI file also means an otherwise small CLI has a real configuration surface.

Timeline

2012: Public GitHub repository created.
2025: README examples document cpi 2.2.0 and C++20/C++23 usage.
2026: Upstream tags include 2.2.x releases and test-release tags.
