About:
WrenCli provides a lightweight command-line interface for the Wren programming language, enabling developers to execute scripts and interact with a REPL environment. It serves as the official CLI companion to the Wren language, offering a straightforward way to test code snippets and run small applications. This tool is ideal for embedded scripting needs or quick automation tasks where a full application framework is unnecessary.

Key Features:

Interactive Read-Eval-Print Loop (REPL)
Script execution from file or standard input
Lightweight and embeddable language runtime
Clean, minimalistic C implementation

Use Cases:

Rapid prototyping and testing of Wren scripts
Embedding a scripting engine into C/C++ applications
Learning and experimenting with the Wren language

Alternatives:

Lua – Lua is a more established scripting language with a larger ecosystem, while Wren offers a more modern, class-based syntax and smaller footprint.
Python – Python provides a vast standard library and is a general-purpose giant, whereas Wren is designed specifically for embedding with minimal overhead.
