Shapeshift

A library to validate and transform data in Lua with special focus on recursively validating tables.

Usage

local shapeshift = require 'shapeshift'
local is = require 'shapeshift.is'

local user = shapeshift.table {
	name = is.string;
	age = is.number;
	address = shapeshift.table {
		street = is.string;
		city = is.string;
		room = shapeshift.any { is.string, is.number }
	}
}

-- Create an example user
local henry = {
	name = "Henry";
	age = 10;
	address = {
		street = "Foo Street";
		city = "City of Bar";
		room = "20 B";
	}
}

-- And validate it
assert(user(henry))
