with

Compile time with for strict mode JavaScript

Installation

$ npm install with

Usage

var addWith = require('with')

addWith('obj', 'console.log(a)')
// => "var a = obj.a;console.log(a)"

addWith("obj || {}", "console.log(helper(a))", ["helper"])
// => var locals = (obj || {}),a = locals.a;console.log(helper(a))

API

addWith(obj, src, [exclude])

The idea is that this is roughly equivallent to:

with (obj) {
  src
}

There are a few differences though. For starters, it will be assumed that all variables used in src come from obj so any that don't (e.g. template helpers) need to have their names parsed to exclude as an array.

It also makes everything be declared, so you can always do:

if (foo === undefined)

instead of

if (typeof foo === 'undefined')

It is also safe to use in strict mode (unlike with) and it minifies properly (with disables virtually all minification).
