Meta Code is a set of metaprogramming utilities for CoffeeScript (inspired by Ruby).
Although you can achieve the same things by hard-coding evrything, 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)
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 a method call to an object property
autoload- load a property from a file
Install with npm:
# install locally in "./node_modules"npm install meta_code# or use -g to install globallynpm install meta_code -g# or add it as a dependecy to your package.json and runnpm 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:
- Use via
metaCode = require 'meta_code'# a "module" we'll be including in our classPower =sword: 'katana': -> consolelog @sword# 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 objectmetaCode @'module'@include Power
- Use directly
module = require 'meta_code/tools/module' # require the tool# a "module" we'll be including in our classPower =sword: 'katana': -> consolelog @swordmoduleincludecall @Power
