> variable argument handling for functions taking a callback
|
|
|
|
rationale
|
|
----------
|
|
|
|
JavaScript has very poor argument handling. *vargs* tries to make it simpler.
|
|
|
|
synopsis
|
|
--------
|
|
|
|
var Args = require("vargs").Constructor;
|
|
|
|
function (/* [arg1, arg2, ...][,callback] */) {
|
|
var args = new(Args)(arguments);
|
|
|
|
args.first; // first argument
|
|
args.last; // last argument before callback
|
|
args.callback; // callback argument, or an empty function
|
|
args.all; // all arguments except callback
|
|
args.length; // number of arguments, not including callback
|
|
|
|
args.callbackGiven(); // returns true or false
|
|
args.at(-1); // last argument, including callback
|
|
args.array; // all arguments, including callback
|
|
}
|
|
