Anyone knows some projects using mruby as their embedded interpreter?

I could think of something like Nginx having a mruby module instead of Lua.

A bunch of games, really.

Besides being used by some game engines as a main programming language (Dragonruby, Ruby2D, and Taylor), it is used by some bespoke game engines as a scripting language as well.

Nier Automata is a somewhat notable example: https://github.com/Martymoose98/NieR-Automata-Ruby-Script-Ex...

Note that Ruby2D aims to run on both ruby and mruby:

> Use a subset of Ruby that works everywhere. Ruby 2D applications are, of course, written in Ruby. Some users may choose to harness the full power of the language, standard library, and ecosystem of gems by writing interpreted apps targeting the standard implementation, MRI. Others may want to target the web via WebAssembly, mobile devices, or build native desktop applications, all which make use of a different Ruby implementation called mruby. Ruby 2D aims to support all of these use cases, even with the same app codebase. Your contribution must support a subset of Ruby that is compatible with and behaves similarly across MRI/CRuby and mruby.

That's interesting, now I'm wondering how many japanese games use it. I know Metal Gear Solid 5 uses Lua.

Nginx already has Javascript [1] which amused me when I found out a year or two back.

I think Shopify was using it to allow scripting in their template system or something like that, but I can't find references right now, other than https://github.com/Shopify/mruby-engine

Not their templating system, but https://help.shopify.com/en/manual/checkout-settings/script-... I believe.

This buildpack used mruby embedded in nginx for some stuff https://github.com/heroku/heroku-buildpack-static

The configuration management tool mitamae is another mruby project: https://github.com/itamae-kitchen/mitamae

There's a name collision with a very important fluorescent protein! mRuby3!

Does this include the Ractor stuff?

lloekivor 3 Jahren

There's no Thread in core mruby (you have to go through a mrbgem[0]), so I don't think there is Ractor stuff in there.

EDIT: confirmed

    $ nix-shell -p mruby
    nix$ mirb
    mirb - Embeddable Interactive Ruby Shell

    > RUBY_VERSION
     => "3.1"
    > Ractor
    uninitialized constant Ractor (NameError)

I believe mruby branched at Ruby 1.9
