Overview

A base codec for string-based formats — HTML forms, query strings, CSV cells — where EVERY value arrives as a string. Unlike Codec::JSON there are almost no native scalars: strings pass through, untyped containers recurse structurally (Rack-style nested params), and everything else maps through an encoder whose input type is a strictly-patterned string.

Config = Types::Hash[port: Types::Integer, active: Types::Boolean, on: Types::Date]
decoder, encoder = Plumb::Codec::Forms.for(Config)
decoder.parse({ port: '80', active: '1', on: '2024-01-30' })
# => { port: 80, active: true, on: Date(2024-01-30) }
