diet-ect-fix

HTML template engine module for diet based on [ect][1]. The Fastest JavaScript template engine with embedded CoffeeScript syntax.

$3

Adam appears to have abandoned Diet, and I'm sick of having to manually fix this every time I start a new Diet project.

This fork fixes 2 problems:
- Actually able to render pages other than "index.html"
- Sends a status code of 200 instead of 404 when serving pages

$3

js

{{ if this.page is 'home' :}}

	Users:

	

		{{for user in this.users :}}

			{{-user.name}} is cool.

		{{end}}

	

{{ else :}}

	404 Page not Found

{{ end }}







Install



npm install diet-ect-fix



Please note the new

v1.0.x only works with diet >=v0.9.17





ECT:

You can learn to use ECT quickly with the

Quick Syntax Guide below or in more detail on ECT's websites. Please note diet-ect by default uses differnt open and curly braces {{ and }}, while ECT by default uses uses <% and %>

.

Usage



#### Server Setup

~/yourApp/index.js

js



// Initialize Server

var server = require('diet')    // Require Diet

var app = server() // Create App

app.listen(8000)   // Configure Domain



// Require ECT

var ect = require('diet-ect')({ path: app.path+'/static' })



// Load ECT as a global header

app.header(ect)



// Listen on GET /

// ECT is a global header so you can access it 

// from every route with the

$.html()

 method

app.get('/', function($){

   // Set a template variable

   $.data.myVar = 'ect'

   

   // Now serve the html file 

   // by default: /your_app/static/index.html 

   // use the

root

 config to change this

   $.html() 

})





#### Write Dynamic HTML

~/yourApp/static/index.html

html





    

        Hello World!

    

    

        Hello World at {{-this.myVar}}





Template Variables

You can access anything defined in the

$ signal

 from your templates including:

js

$.query 	// in template {{ this.query }}

$.body 		// in template {{ this.body }}

$.params 	// in template {{ this.params }}

$.url 		// in template {{ this.query}}

$.data 		// in template {{ this }} data is a special variable





The $.data variable

- The

$.data

 object has a priority and will overwrite the variables from the signal. 

- The

$.data variable is directly accessible like {{-this.myVar}} instead of {{-this.data.myVar}}

.

- The

$.data object is also used by the $.json()

 response making APIs easier to build.



Custom file

By default

$.html() will serve an index.html file relativ to the root

 config.

js

$.html('yourFile.html') // will serve /your_app/static/yourFile.html





You can change the file when you call

$.html()

 by passing in an argument with a different path.



Config

You can use any config that [ECT][2] already has. These are the defaults with

diet-ect

js

require('diet-ect')({

	root : '/', 

	ext: '.html', 

	open: '{{', close: '}}',

	cache: true,

	watch: true,

	gzip: true

})





Quick Syntax Guide



$3



#### Escaped Output

js

{{- this.title }}



#### Unescaped Output

js

{{= this.source }}





$3



#### If

js

{{if this.is :}}

	then show this

{{end}}





#### If - Else

js

{{ if this.is :}}

	then show this

{{ else :}}

	otherwise show this

{{ end }}





#### If - Else If - Else

js

{{ if this.is :}}

	then show this

{{ else if this.otherwise :}}

	otherwise show this

{{ else :}}

	every other way show this

{{ end }}





$3



Let's say this is our project structure:

js

/views

....../html

............/header.html

............/home.html

............/about.html





And we would like to resue

header.html in both home.html and about.html

.



This is

header.html

js



	A Wonderful Service



And this is

home.html

js

{{ include 'header' }}

Welcome to my homepage

...



And this is

about.html

js

{{ include 'header' }}

About Me

...





Voala! You can use

.html

 in the include string but it is not necessary. Please note if you define a new variable inside a template it will only be passed to included files if it was defined within the

this

 variable. 



$3

#### Looping Through Array

The data:

js

$.data.letters = ['A', 'B', 'C']



The template:

js

{{for letter in this.letters :}}

	{{-letter}} 


{{end}}



The output:

js

A

B

C



#### Looping Through Object

The data:

js

$.data.capitals = { a: 'A', b: 'B', c: 'C' }



The template:

js

{{for key, value of this.capitals :}}

	{{-key}}: {{-value}} 


{{end}}



The output:

js

a: A

b: B

c: C





Please note if you would like to iterate over just the keys that are defined on the object itself, by adding a

hasOwnProperty

 check to avoid properties that may be inherited from the prototype, use the own directive in the looping syntax like:

js

{{for own key, value of object :}}

	{{-key}}: {{-value}} 


{{end}}





#### Looping Through Array of Objects

The data:

js

$.data.grades = [

	{ student: 'Arnold', value: 'A+' }, 

	{ student: 'Billy', value: 'B+' }, 

	{ student: 'Carol', value: 'C-' }

];



The template:

js

{{for grade in this.grades :}}

	{{-grade.student}} received {{-grade.value}} 


{{end}}



The output:

js

Arnold received A+

Billy received B+

Carol received C-



#### Looping Through Array with Indexes

The data:

js

$.data.letters = ['A', 'B', 'C']



The template:

js

{{for value, index in this.letters :}}

	{{-index}}. {{-value}} 


{{end}}



The output:

js

1. A

2. B

3. C





$3



#### Simple Function Declaration

js

{{ link = (url, text) -> }}

	{{- text }}

{{ end }}





	{{-link '/', 'home'}}

	{{-link '/about', 'about'}}

	{{-link '/contact', 'contact'}}





#### Using Local Template Variables



Please note you cannot access template variables that are created locally within the template unless it is defined as a property of the global context object

this

.



This IS working:

html



{{this.preText = 'Learn more about '}}



{{ myFunction = (text) -> }}

	{{- this.preText }} {{- text }}

{{ end }}





{{-text 'football'}}

{{-text 'hockey'}}



This IS NOT working:

html



{{preText = 'Learn more about: '}}





{{ myFunction = (text) -> }}

	{{- preText }} {{- text }}

{{ end }}





{{-text 'football'}}

{{-text 'hockey'}}





$3

As you can see the colon punctuation

 is sometimes used and sometimes not. It can be confusing at the beginning but hopefully this will save you some time:



The

: is only needed for if else-if else and for` directives - for everything else you don't need it.
