TOML for mruby (https://toml.io/)

A lightweight, standards-aligned TOML implementation for mruby. Designed to feel natural in Ruby while staying fast, small, and compatible with the TOML 1.1 specification.

Features

• TOML parsing and dumping
• Tables → Hash
• Arrays → Array
• Strings, integers, floats, booleans
• TOML date, time, and datetime values mapped to Ruby Time objects with TOML-aware metadata
• Round-trip safe: parsed values dump back to valid TOML
• Built on top of toml11, a mature and well-tested MIT-licensed TOML library

Usage

with files

cfg = TOML.load("config.toml")
puts cfg["server"]["port"]
cfg.dump("config_copy.toml")
TOML.dump({server: {addr: "127.0.0.1", port: 8080}}, "dump.toml")

with strings

h = { bool: true, int: 1, float: 1.0, str: "hello" }
dumped = TOML.dump(h)
data = TOML.parse(dumped)

Installation

Add this gem to your build_config.rb:

conf.gem mgem: "mruby-toml"
