π‘Around code (news, findings, books, and more - all about Ruby)
π‘ Ruby Association announced the 2024 Ruby Association Grant selection result. There were 3 projects selected:
βPicoRuby2: New PicoRuby Using mruby as VMβ - Hitoshi Hasumi
βThis project will integrate the mruby as a general-purpose embedded language with the PicoRuby ecosystem, which has expertise in microcontroller application development, aiming to bring ISO/IEC 30170-compliant Ruby to microcontroller programming and expand the scope of application developmentβ
βImplementing a plugin system for RDocβ - Masafumi Okura
βThis project aims to implement a plugin system in RDoc so that RDoc can meet diverse requirements and demands and become the central tool for Ruby documentation.β
βCreating a 2D retro game engine based on Processing Gemβ - tokujiros
βBased on last yearβs project, βProcessing Gem for CRuby, working towards better compatibility with the original Processingβ we will leverage the results, namely the Processing Gem, to develop a new 2D retro game engine.
This game engine targets retro games and intentionally limits specifications such as resolution, color palette, and audio features. By simplifying the development process in this way, we aim to create an environment where even beginners can easily start developing games.β
