Pandora (/pænˈdɔːrə/ pan-DOR-ə; Greek: Πανδώρα, from the XVII moon of Saturn) is a small pure-lua object oriented library.
Pandora adds classes with the common class syntax to Lua, which makes you able to build classes without the need of transpilation (Like Moonscript, which is a great language by the way), and without the classical metatable syntax.
An example of a module, let this "file" be Person.lua:
-- Remember to import class and operator functions!
----
-- Person example
----
return class 'Person' {
----
-- Name
-- @type {string}
----
name = '<no name>',
----
-- Constructor
-- @param {string} name
----
Person = function(this, name)
this.name = name
end,
----
-- Compares two persons by name
-- @param {string} other
----
[operator'=='] = function(this, other)
return this.name == other.name
end,
----
-- Shouts the name
----
shout = function(this)
print('My name is ' .. this.name .. '!')
end
}And use just like:
local Person = require 'Person'
local john = Person('John')
john:shout()Extending is easy:
local Building = class 'Building' {
foo = function(this) println('foo') end
}
local House = class 'House' { [extends] = Building,
bar = function(this) println('bar') end
}Tested with Lua 5.3.
