shift

Shift.js

Standard Interface to the Node.js Template Engines.

Install

npm install shift

Engines

new Shift.CoffeeScript
new Shift.Ejs
new Shift.Haml
new Shift.Jade
new Shift.Less
new Shift.Markdown
new Shift.Mustache
new Shift.Stylus
new Shift.UglifyJS
new Shift.YuiCompressor

Example

Shift     = require('shift')
mustache  = new Shift.Mustache()
mustache.render "{title}!", locals: title: "Hello World", (string) -> console.log(string) #=> "Hello World!" 

or more formally:

engine    = new Shift.Jade
input     = fs.readFileSync("./spec/fixtures/views/jade.jade", "utf-8")
output    = fs.readFileSync("./spec/fixtures/views/jade.html", "utf-8")
engine.render input, (error, result) ->
  expect(result).toEqual output

API

engine = new Shift.CoffeeScript
engine.render(string, options, callback)

Preprocessing

Sometimes you might need to hack in a feature to the language. Like right now, stylus doesn't support multiline values for css attributes, so you might add it like this:

engine  = new Shift.Stylus
 
input   = '''
div
  box-shadow: 0 -2px 2px  hsl(220, 20%, 40%),
    0 -10px 10px          hsl(220, 20%, 20%),
    0 0 15px              black,
 
    inset 0 5px 1px       hsla(220, 80%, 10%, 0.4), 
    inset 0 0 5px         hsla(220, 80%, 10%, 0.1),
    inset 0 20px 15px     hsla(220, 80%, 100%, 1),
 
    inset 0 1px 0         hsl(219, 20%, 0%), 
 
    inset 0 -50px 50px -40px hsla(220, 80%, 10%, .3),  /* gradient to inset */
 
    inset 0 -1px 0px      hsl(220, 20%, 20%),
    inset 0 -2px 0px      hsl(220, 20%, 40%),
    inset 0 -2px 1px      hsl(220, 20%, 65%)  
'''
 
output  = '''

  box-shadow: 0 -2px 2px #525f7a, 0 -10px 10px #29303d, 0 0 15px #000, inset 0 5px 1px rgba(5,19,46,0.40), inset 0 0 5px rgba(5,19,46,0.10), inset 0 20px 15px #fff, inset 0 1px 0 #000, inset 0 -50px 50px -40px rgba(5,19,46,0.30), inset 0 -1px 0px #29303d, inset 0 -2px 0px #525f7a, inset 0 -2px 1px #94a0b8;
}
