# IRust Repl
Repl engine used by IRust to interpret rust code
The core is `println!("{:?}", expression)` with tricks to conserve variables and context
Example:
```rust
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 Jupyter Kernel is provided https://github.com/sigmaSd/IRust/tree/master/crates/irust_repl/irust_kernel, to use it:
Installation
------------
This requires IPython 3.
pip install irust_kernel
python -m irust_kernel.install
To use it, run one of:
code # vscode have the best implementation
zed # zed implementation is nice as well
jupyter notebook
# In the notebook interface, select IRust from the 'New' menu
jupyter qtconsole --kernel irust
jupyter console --kernel irust
Developement
------------
This requires https://github.com/pypa/flit
To start developping locally use `flint install --symlink` optionally followed by `python -m irust_kernel.install --local-build` if there are changes to `Re` executable
Examples
----------
irust.ipynb (simple showcase) and evcxr.ipynb (showcase of evcxr protocol) are provided as an example
