# CoffeeKup <☕/>
## Markup as CoffeeScript
CoffeeKup is a templating engine for [node.js](http://nodejs.org) and browsers that lets you to write your HTML templates in 100% pure [CoffeeScript](http://coffeescript.org).
It was created in celebration of [whyday](http://whyday.org/), as an application of the concept used in [Markaby](https://github.com/markaby/markaby) ("Markup as Ruby", by Tim Fletcher and why the lucky stiff) to CoffeeScript.
Here's what a template written for CoffeeKup looks like:
doctype 5
html ->
head ->
meta charset: 'utf-8'
title "#{@title or 'Untitled'} | A completely plausible website"
meta(name: 'description', content: @description) if @description?
link rel: 'stylesheet', href: '/css/app.css'
style '''
body {font-family: sans-serif}
header, nav, section, footer {display: block}
'''
script src: '/js/jquery.js'
coffeescript ->
$(document).ready ->
alert 'Alerts suck!'
body ->
header ->
h1 @title or 'Untitled'
nav ->
ul ->
(li -> a href: '/', -> 'Home') unless @path is '/'
li -> a href: '/chunky', -> 'Bacon!'
switch @user.role
when 'owner', 'admin'
li -> a href: '/admin', -> 'Secret Stuff'
when 'vip'
li -> a href: '/vip', -> 'Exclusive Stuff'
else
li -> a href: '/commoners', -> 'Just Stuff'
div '#myid.myclass.anotherclass', style: 'position: fixed', ->
p 'Divitis kills! Inline styling too.'
section ->
# A helper function you built and included.
breadcrumb separator: '>', clickable: yes
h2 "Let's count to 10:"
p i for i in [1..10]
# Another hypothetical helper.
form_to @post, ->
textbox '#title', label: 'Title:'
textbox '#author', label: 'Author:'
submit 'Save'
footer ->
# CoffeeScript comments. Not visible in the output document.
comment 'HTML comments.'
p 'Bye!'

## _why?
- **One language to rule them all**. JavaScript is everywhere, thus so is CoffeeScript. Servers, browsers, even databases. If extending this to rendering logic and UI structure (server and client side) is desirable to you, CoffeeKup is your friend.
- **More specifically, one _outstanding_ language**. CoffeeScript is one hell of a clean, expressive, flexible and powerful language. It's hard to find such combination, especially if you need it to run in the browser too.
- **Not yet another specialized language to learn**. Transferable knowledge FTW.
- **Embed your templates in CoffeeScript nicely**. Templates are just functions, so they don't lose syntax highlighting and syntax checking when embedded in CoffeeScript apps.
- **Embed CoffeeScript in your templates nicely**. In the same manner, you can write the contents of `` blocks in CoffeeScript, and keep the highlighting. Perhaps more significantly, the CoffeeScript compiler doesn't have to be called just to convert these blocks to JS, as in other templating engines.
- **Extensive editor support**. You benefit from the already existing list of excellent CoffeeScript [text editor plugins](https://github.com/jashkenas/coffee-script/wiki/Text-editor-plugins).
- **Client-server consistency**. The same template language _and_ implementation in node.js or the browser.
- **Easily extendable into a higher level "DSL"**. Since all elements are just functions, it's very easy to define your own custom "tags", which will work and look the same as "native" ones.
- **HTML 5 ready**. Boring legacy doctypes and elements also available.
- **Optional auto-escaping**. You can also use the `h` helper on a case-by-case basis.
- **Optional formatting**, with line breaks and indentation.
- **Pick your poison**. Works with both CoffeeScript and JavaScript apps.
## Why not?
CoffeeKup may not be your best choice in those cases:
- You're after the cleanest syntax possible, above all. In this regard a specialized language such as [Jade](http://jade-lang.com) just can't be beaten.
- You use divs and/or classes for everything. While in CoffeeKup you can do `div '#id.class.class'`, specialized languages often have an even shorter syntax for that.
- You want CoffeeScript for rendering logic, but you'd rather stick with HTML for markup. Then you're looking for [Eco](http://github.com/sstephenson/eco).
- For your specific project/team/preferences, you think a limited and/or separate language for templating is actually beneficial.
## Installing
Just grab [node.js](http://nodejs.org/#download) and [npm](http://github.com/isaacs/npm) and you're set:
npm install coffeekup
To get the `coffeekup` command, install it globally:
npm install coffeekup -g
Or to use the latest version:
git clone [email protected]:mauricemach/coffeekup.git && cd coffeekup
cake build
npm link
cd ~/myproject
npm link coffeekup
## Using
ck = require 'coffeekup'
ck.render -> h1 "You can feed me templates as functions."
ck.render "h1 'Or strings. I am not too picky.'"
Defining variables:
template = ->
h1 @title
form method: 'post', action: 'login', ->
textbox id: 'username'
textbox id: 'password'
button @title
helpers =
textbox: (attrs) ->
attrs.type = 'text'
attrs.name = attrs.id
input attrs
ck.render(template, title: 'Log In', hardcode: helpers)
Precompiling to functions:
template = ck.compile(template, locals: yes, hardcode: {zig: 'zag'})
template(foo: 'bar', locals: {ping: 'pong'})
With [express](http://expressjs.com):
app.set 'view engine', 'coffee'
app.register '.coffee', require('coffeekup').adapters.express
app.get '/', (req, res) ->
# Will render views/index.coffee:
res.render 'index', foo: 'bar'
With [zappa](http://github.com/mauricemach/zappa):
get '/': ->
@franks = ['miller', 'oz', 'sinatra', 'zappa']
render 'index'
view index: ->
for name in @franks
a href: "http://en.wikipedia.org/wiki/Frank_#{name}", -> name
With [meryl](https://github.com/kadirpekel/meryl/tree/master/examples/coffeekup-template):
coffeekup = require 'coffeekup'
meryl.get '/', (req, resp) ->
people = ['bob', 'alice', 'meryl']
resp.render 'layout', content: 'index', context: {people: people}
meryl.run
templateExt: '.coffee'
templateFunc: coffeekup.adapters.meryl
On the browser:
<script src="template.js">
$('body').append(templates.template({foo: 'bar'}));
This is one of many browser deployment possibilities, pre-compiling your template on the server to a standalone function. To see all serving suggestions, check out [regular](http://github.com/mauricemach/coffeekup/blob/master/examples/browser/regular/index.html), [decaf](http://github.com/mauricemach/coffeekup/blob/master/examples/browser/decaf/index.html) and [crème](http://github.com/mauricemach/coffeekup/blob/master/examples/browser/creme/index.html).
Command-line:
$ coffeekup -h
Usage:
coffeekup [options] path/to/template.coffee
--js compile template to js function
-n, --namespace global object holding the templates (default: "templates")
-w, --watch watch templates for changes, and recompile
-o, --output set the directory for compiled html
-p, --print print the compiled html to stdout
-f, --format apply line breaks and indentation to html output
-u, --utils add helper locals (currently only "render")
-v, --version display CoffeeKup version
-h, --help display this help message
See [/examples](http://github.com/mauricemach/coffeekup/tree/master/examples) for complete versions (you have to run `cake build` first).
Please note that even though all examples are given in CoffeeScript, you can also use their plain JavaScript counterparts just fine.
