TOML

The TOML module allows parsing TOML documents through the usage of the tomlc99 C library

Parsing with TOML.parse

TOML.parse will return an Any, which is a convenient wrapper around all possible TOML types, making it easy to traverse a complex TOML structure but requires some casts from time to time, mostly via some method invocations.

require "ctoml-cr"

value = TOML.parse("x=[1, 2, 3]") # : TOML::Any

value[0]              # => 1
typeof(value[0])      # => TOML::Any
value[0].as_i         # => 1
typeof(value[0].as_i) # => Int32

value[0] + 1      # Error, because value[0] is TOML::Any
value[0].as_i + 1 # => 2
