/*

Replace text template for parameter hash table

Ex:
$mytext = 'Hi, my name is {%name%}, and my address is {%address%}';
rep_templates($mytext, array('name'=>'Steven', 'address'=>'Rua Beira Mar, 12'));
print $text; //Output: Hi, my name is Steven, and my address is Rua Beira Mar, 12

Other ex.

$row = mysql_fetch_assoc($my_result_from_query);

$mytext = file_get_contents('./text_for_email_template.txt');

tranf_dados($mytext, $row);

sendmail($row['email', 'Subject:Hi mane!', $mytext);

Java Cons class

frost137 (Douglas Wyatt) — Mon, 21 Apr 2008 23:43:50 GMT

Very simple Cons class for Java



public class Cons

{

    private T car;

    private U cdr;



    public Cons( T carArg, U cdrArg )

    {

        car = carArg;

        cdr = cdrArg;

    }



    public T getCar(){ return car; }

    public U getCdr(){ return cdr; }

}

Common Trim function for XSLT (as a template)

Exception Assertion Template For Eclipse

guanzo (guanzo) — Thu, 15 Mar 2007 12:00:15 GMT

Eclipse template for exception assertion (Create template in Eclipse > Preferences > Java > Editor > Templates > New ... OK)

How to use:
1. Select code throwing exception
2. Alt + Shift + Z -> select corresponding template.



        try

        {

            ${line_selection}${cursor}

            fail("${Exception} expected.");

        }

        catch (${Exception} e)

        {

            assertEquals(${message}, e.getMessage());

        }

Java Singleton Template for Eclipse

marcelotmelo (Marcelo Melo) — Fri, 02 Mar 2007 19:42:35 GMT

This is a template for easily creating an implementation of the Singleton Pattern on Eclipse. Open Window->Preferences->Java->Editor->Templates click on New and insert the code below on the pattern text area; add a name (I suggest "singleton") - whenever you type this name and press Ctrl+Space the code will be inserted in your class - and you're good to go.



private static ${enclosing_type} instance;



private ${enclosing_type}(){}



public static ${enclosing_type} getInstance(){

	if(null == instance){

		instance = new ${enclosing_type}();

	}

	return instance;

}

Ruby style string injection via Prototype Templates

leftist (Pete Forde) — Tue, 30 Jan 2007 03:07:08 GMT

Requires Prototype 1.5

I'm honestly not sure why they didn't do this out of the box.



Object.extend(String.prototype, {

  mixin: function(obj) {

    return new Template(this).evaluate(obj);

  }

});

Oh, yes.



"#{company} forever!".mixin({company: 'Unspace'}) // Unspace forever!

Simplest possible PHP templating engine

tatarynowicz (Michal Tatarynowicz) — Tue, 28 Nov 2006 18:55:29 GMT

// This code takes a template name and an array of variables
// and parses them with a file
//
// Example:
// print template('hello', array('who'=>'world'));
//
// Template (/templates/hello.html)
// Hello !
//
// Outputs:
// Hello world!



define('DIR_TEMPLATES', dirname(__FILE__).'/templates');



function template($__name__, $__data__=array()) {

	extract($__data__);

	ob_start();

	require(DIR_TEMPLATES.'/'.$__name__.'.html');

	return ob_get_clean();

}

Running erb templates from the command line

bradphelan (Brad Phelan) — Tue, 21 Mar 2006 00:30:43 GMT

The following script takes the name of a template as it's argument. Within the
template the command erb is in scope to call more templates. I wrote this for a friend who was having hell with NVU templates and I suggested to write the code by hand and use this script to build his static pages.



#!/usr/bin/ruby

# Quick and dirty template processing script. It takes

# as an argument the name of the first template script

# and then executes it to standard output.



require "erb"





class QuickTemplate

   attr_reader :args, :text

   def initialize(file)

      @text = File.read(file)

   end

   def exec(args={})

      b = binding

      template = ERB.new(@text, 0, "%<>")

      result = template.result(b)

      # Chomp the trailing newline

      result.gsub(/\n$/,'')

   end

end



def erb(file, args={})

   QuickTemplate.new(file).exec(args)

end



puts erb(ARGV[0])

The erb command itself takes an optional argument of a hash which is passed to the template as the
variable name args. Thus you can parameterize your sub templates.

Call the command as



ruby erb_run.rb main.thtml

The main template





   

   

   

    <%= erb("title.thtml") %>

and the sub template title.thtml
