Trivia
Etymology of the name “Rhai” as per Rhai’s author Johnathan Turner
In the beginning there was ChaiScript, which is an embedded scripting language for C++. Originally it was intended to be a scripting language similar to JavaScript.
With java being a kind of hot beverage, the new language was named after another hot beverage – Chai, which is the word for “tea” in many world languages and, in particular, a popular kind of spicy milk tea consumed in India.
Later, when the novel implementation technique behind ChaiScript was ported from C++ to Rust,
logically the C was changed to an R to make it “RhaiScript”, or just “Rhai”.
On the origin of the semi-official Rhai logo
One of Rhai’s maintainers, @schungx, was thinking about a logo
when he accidentally came across a copy of Catcher in the Rye in a restaurant, and drew the first
version of the logo.
Then @semirix refined it to the current version.
The plan is to make the logo official together with a 1.0 release.
