RuntimeGems for PicoRuby

RuntimeGems are a collection of libraries for PicoRuby, implemented in pure Ruby. You can upload them to R2P2 via https://picoruby.org/runtimegems.

Support for this feature will be available in an upcoming R2P2 release, scheduled just before RubyKaigi 2026.

Adding a Gem

Fork this repository, add a new [name].yaml file that contains your gem's info, and send the PR.

• [name] must be unique
• RuntimeGem must contain only Ruby implementation. C implementation is never going to be handled
• In general, [name] should start with "picoruby-". If it has a reason not to do, you need to write spec.require_name "hoge" in mrbgem.rake so that you can load it by require "hoge"

Example

name: picoruby-aht25
repo: https://github.com/picoruby/picoruby
path: mrbgems/picoruby-aht25/
ref: master
description: AHT25 sensor library for PicoRuby
tags:
  - AHT25
  - temperature
  - humidity
  - I2C

• All the items other than path and tags are mandatory
• When path is blank, mrbgem.rake and mrblib/ are supposed to locate at the top directory
• Keep the description concise
