proxy-function-stack

proxy-function-stack (pst) is a library using ES Harmony proxies. It enables you to write functions such as mapping ones easier - no more verbose stuff like:

arr.map(function(item) {
  return item.foo().bar();
});

... but just:

arr.map( pst.foo().bar() );

Install

npm install pst

Requirements

Works with V8 3.8.8 (node 0.7.1). Make sure to run with the --harmony_proxies flag!

Usage

var pst = require("pst");

// now you can use it like in the example below

Example

Consider the following variables:

var arr = ["foo", "Bar", "some_123_thing"],

    rdigit = /\d/g,

    multiply = function(x) {
      return x * 3;
    };

Old

var mapped = arr.map(function(element) {
  return element.toUpperCase()
                .slice(0, -1)
                .replace(rdigit, multiply);
});

New

var mapped = arr.map( pst.toUpperCase()
                         .slice(0, -1)
                         .replace(rdigit, multiply) );

Result

["FO", "BA", "SOME_369_THIN"]
