PLEAC

I found nice project that tries to create ebooks (html pages). These ebooks are copy of Perl Cookbook but using different programming languates:

Apache Velocity

Velocity consists of two main parts, Template and Context. Where template holds html, xml etc. and references, directives etc. Context holds the data.

Using Strig as template:

Context ctx = new VelocityContext();
ctx.put("user", "Admin user");

StringWriter writer = new StringWriter();
/* used as the template name for log messages in case of error */
String logTag = "template name";
String templateString = "<div>$user</div>";

Velocity.evaluate(ctx, writer, logTag, templateString);
System.out.println(writer.getBuffer());

Using Velocity Template

RuntimeServices runtimeServices = RuntimeSingleton.getRuntimeServices();
Template template = new Template();
template.setRuntimeServices(runtimeServices);

StringReader reader = new StringReader("<div>$user</div>");
SimpleNode node = runtimeServices.parse(reader, "template name");
template.setData(node);
template.initDocument();

// ... create context and writer

template.merge(context, writer);

Merge method (template.merge(context, writer)) calls render method on its data (template.setData(node)), which is instance of SimpleNode.

SimpleNode then calls merge method on every child it has (SimpleNode or subclass of SimpleNode). Every part of the template (text, references, directives etc.) are represented as SimpleNode (or its subclass).

Knowing this we can for example count number of references (instances of ASTReference) in the template:

SimpleNode simpleNode = (SimpleNode) template.getData();

for (int x = 0; x < simpleNode.jjtGetNumChildren(); x++) {
    if (simpleNode.jjtGetChild(x) instanceof ASTReference) {
        ASTReference astRef = (ASTReference) simpleNode.jjtGetChild(x);
        // root reference without $, so '$user.name' becomes 'user'
        System.out.println(astRef.getRootString());
        // literal reference, so '$user.name' is '$user.name'
        System.out.println(astRef.literal());
    }
}

Loading resource from classpath

The following code loads resource (in this case spring macro).

StringBuilder springMacro = new StringBuilder();
ClasspathResourceLoader resourceLoader = new ClasspathResourceLoader();
Scanner sc = new Scanner(resourceLoader.getResourceStream(
        "org/springframework/web/servlet/view/velocity/spring.vm"));
while(sc.hasNextLine()) {
    springMacro.append(sc.nextLine());
}

System.out.println(springMacro.toString());

This is needed only when using spring macro (spring.vm), so it has requestContext reference (needed for binding - #springBind(...))

VelocityContext context = new VelocityContext();
// request is instance of HttpServletRequest and mav is instance of ModelAndView
context.put("springMacroRequestContext", new RequestContext(request, mav.getModel()));

Using Velocity Tools

With standalone velocity, you can configure tools (tools.xml) this way:

ToolManager manager = new ToolManager();
/* path to tools.xml */
manager.configure("/path/to/my/configuration.xml");
Context context = manager.createContext();
myVelocityEngine.evaluate(context, myOutputWriter, 
        "This is a $text.test", "Test template");

PHP Environment setup - Netbeans, PHPUnit and xdebug

- filenames (paths) will be different for every platform/version
wamp server
Install wamp:
http://www.wampserver.com/en/

pear
open command line, go to:

C:\wamp\bin\php\php5.3.0

execute: 

php -d phar.require_hash=0 PEAR/go-pear.phar

and choose all defualt options (first option)

xdebug
start wamp sever and enable php curl extension

copy php info output and paste it here:
http://www.xdebug.org/find-binary.php
it shows you what xdebug version to download and where to put it

modify both php.ini (c:\wamp\bin\php\php5.3.0\php.ini and c:\wamp\bin\apache\Apache2.2.11\bin\php.ini)
add these lines at the end:

zend_extension = c:\wamp\bin\php\php5.3.0\ext\php_xdebug-2.1.0-5.3-vc6.dll

xdebug.remote_enable=on

xdebug.remote_handler=dbgp

xdebug.remote_host=localhost

xdebug.remote_port=9000

your xdebug version could be different
restart apache server

netbeans
download and install netbeans (php)
http://netbeans.org/downloads/

phpunit
type on command line:

pear upgrade pear

pear channel-discover pear.phpunit.de

pear channel-discover pear.symfony-project.com

pear install phpunit/PHPUnit

make sure that you included PEAR in both php.ini:

include_path = ".;c:\wamp\bin\php\php5.3.0\PEAR"

restart apache

integrate with netbeans
in netbeans go to:
Tools -> Options -> PHP

under general tab, PHP 5 Interpreter:
C:\wamp\bin\php\php5.3.0\php.exe
Debugger port: 9000
Session ID: netbeans-xdebug

Under Unit Testing tab:
PHPUnit script: C:\wamp\bin\php\php5.3.0\phpunit.bat
