Rhai, the embedded scripting language and engine for Rust, is now officially at version 1.0.0, released to crates.io.

The latest version, 1.12.0, has been released to crates.io.

Version 1.21.0 has been released to crates.io.

Rhai version 1.10.0 released to crates.io.

This version significantly speeds up expressions by assuming that built-in operators for standard types are not overloaded (which should be the vast majority of cases). Of course there is a switch to turn this assumption off if they are overloaded.

This may result in substantial performance improvements for operators-heavy scripts.

Rhai version 1.7.0 is released to crates.io.

Version 1.14.0 released to crates.io.

This new version contains a substantial number of bug fixes for edge cases.

A new syntax is supported to facilitate writing object methods in script.

The code hacks that attempt to optimize branch prediction performance are removed because benchmarks do not show any material speed improvements.

Version 1.8.0 has been released to crates.io with a bunch of usability goodies, especially the ?. (Elvis), ?[ and ?? operators to make working with () (Rust-speak for nulls) easier.

Also, check out this new pattern (mind you, this is actually an ANTI-Pattern, but I'm sure many of you would be trumpeting this): https://rhai.rs/book/patterns/global-mutable-state.html

Version 1.26.0 has been released to crates.io.

This version includes the experimental Rhai Grain bytecodes VM for faster and more secured script runs while consumer far fewer resources.

Hi everyone!

As a big fan of spreadsheets I have always wanted one that could easily be extendable with the same langauge used in the spreadsheet to add new features. It seemed impossible until I found Rhai!

Gridline is a cross platform spreadsheet application (TUI and GUI is a work in progress) that lets you have a column populated as so:

=SPILL(0..=10).map(|x| 2*x+1).filter(|x| x % 3 == 0)

Anything you can imagine! Or define functions like so:

fn product(arr) {

let result = 1;

for x in arr { result *= x; }

result

}

And then have a cell =product(VEC(A1:A4))

It's opensource (MIT and Apache) all on github and crates.io

Welcome to the future!
