Meta Code is a set of metaprogramming utilities for CoffeeScript (inspired by Ruby).

Although you can achieve the same things by hard-coding everything, this package is good because function names convey meaning, and is good to have consensus among developers.

Curently, the folowing tools are provided (nicely documented in the code)

• module

  • extend - copies the module object's methods onto an object
  • include - copies the module object's methods onto an object's prototype
  • includeInter - inject a shallow copy of the module object into an object's prototype chain

• forward

  • forward - forward a method call to an object property

• autoload

  • autoload - load a property from a file

• extract_options

  • extract_options - extract options from function arguments

Install with npm:

# install locally in "./node_modules"
npm install meta_code
# or use -g to install globally
npm install meta_code -g
# or add it as a dependecy to your package.json and run
npm install

Metacode consists of a series of tools like "forward" or "module" that aid you to inject code in your objects. There are two interfaces that can be used:

1. Use via metaCode helper

metaCode = require 'meta_code'
# a "module" we'll be including in our class
Power =
  sword: 'katana'
  fight: -> console.log @sword
class Samurai
  # Enable the module tool. Once enabled we can use this tool's methods 
  # like 'extend' and 'include' in our object, because the tool's methods 
  # get copied in our object
  metaCode @, 'module'
  @include Power

2. Use directly

module = require 'meta_code/tools/module' # require the tool
# a "module" we'll be including in our class
Power =
  sword: 'katana'
  fight: -> console.log @sword
class Samurai
  module.include.call @, Power
