Clone repository

git clone https://github.com/evcxr/evcxr.git

An evaluation context for Rust.

This project consists of several related crates.

evcxr_jupyter - A Jupyter Kernel
evcxr_repl - A Rust REPL
evcxr - Common library shared by the above crates, may be useful for other purposes.
evcxr_runtime - Functions and traits for interacting with Evcxr from libraries that users may use from Evcxr.

If you think you'd like a REPL, I'd definitely recommend checking out the Jupyter kernel. It's pretty much a REPL experience, but in a web browser.

To see what it can do, it's probably best to start with a tour of the Jupyter kernel. Github should allow you to preview this, or you can load it from Jupyter Notebook and run it yourself.
