IRust Repl

Repl engine used by IRust to interpret rust code

The core is println!("{:?}", expression) with tricks to conserve variables and context

Example:

use irust_repl::{Repl, ToolChain};

let mut repl = Repl::new(ToolChain::Stable).unwrap();
repl.insert("let a = 5");
assert_eq!(repl.eval("a+a").unwrap().output, "10");

Jupyter Kernel

A basic jupyer kernel is provided for demo https://github.com/sigmaSd/IRust/tree/master/crates/irust_repl/irustkernel, to use it:

• Compile re example with cargo build --examples --release
• Cp re to a folder in your $PATH so it can be used by the kernel, cp target/release/examples/re $folder_in_path
• Install the kernel with jupyter kernelspec install --user irustkernel, it should be listed now in jupyter kernelspec list
• Cd to irustkernel, and run jupyter, jupyter lab ., note: cding into irustkernel is important so python can find the module irust (irust.py), the path is hardcoded in kernel.json

That's it! irust.ipynb is provided as an example
