0.1.0 • Public • Published

garde

npm version Travis CI Badge (master branch)

Utility function for dealing with function arguments.

How to include

Node.js / Browserify

In your shell:

$ npm install --save garde

In your javascript:

var garde = require('garde')

Browser ("classic" way)

Just add a script tag with either garde.js or garde.min.js from this repos root directory. This makes the Cheiron variable globally available.

typeof window.garde
// --> 'function'

Warning

This module globally extends the prototype of Function with a method invoke which uses the evil eval! But I sorrily JS did not give me another way to call a function with an array of arguments without changing it's context.

API

garde(<f>)

Returns a wrapper function for f which throws an Exception when the number of arguments passed does not equal f's arity.

var add = function (a, b) {
  return a + b
}
 
console.log(add(1, 2))
// --> 3
 
console.log(add(1))
// --> NaN
 
var gAdd = garde(add)
 
console.log(gAdd(1, 2))
// --> 3
 
console.log(gAdd(1))
// Error: Function needs 2 arguments, got 1

garde(<arity>, <f>)

Instead of checking f's arity, arity is used for comparison.
