#[[ hello steve

   This has invalid syntax that would normally need "poor man's escaping" like:

​

   #define()

​

   ${blah

]]#

​

#include( "disclaimer.txt" "opinion.txt" )

#include( $foo $bar )

​

#parse( "lecorbusier.vm" )

#parse( $foo )

​

#evaluate( 'string with VTL #if(true)will be displayed#end' )

​

#define( $hello ) Hello $who #end #set( $who = "World!") $hello ## displays Hello World!

​

#foreach( $customer in $customerList )

​

    $foreach.count $customer.Name

​

    #if( $foo == ${bar})

        it's true!

        #break

    #{else}

        it's not!

        #stop

    #end

​

    #if ($foreach.parent.hasNext)

        $velocityCount

    #end

#end

​

$someObject.getValues("this is a string split

        across lines")

​

$someObject("This plus $something in the middle").method(7567).property

​

#macro( tablerows $color $somelist )

    #foreach( $something in $somelist )

        <tr><td bgcolor=$color>$something</td></tr>

        <tr><td bgcolor=$color>$bodyContent</td></tr>

    #end

#end

​

#tablerows("red" ["dadsdf","dsa"])

#@tablerows("red" ["dadsdf","dsa"]) some body content #end

​

   Variable reference: #set( $monkey = $bill )

   String literal: #set( $monkey.Friend = 'monica' )

   Property reference: #set( $monkey.Blame = $whitehouse.Leak )

   Method reference: #set( $monkey.Plan = $spindoctor.weave($web) )

   Number literal: #set( $monkey.Number = 123 )

   Range operator: #set( $monkey.Numbers = [1..3] )

   Object list: #set( $monkey.Say = ["Not", $my, "fault"] )

   Object map: #set( $monkey.Map = {"banana" : "good", "roast beef" : "bad"})

​

The RHS can also be a simple arithmetic expression, such as:

Addition: #set( $value = $foo + 1 )

   Subtraction: #set( $value = $bar - 1 )

   Multiplication: #set( $value = $foo * $bar )

   Division: #set( $value = $foo / $bar )

   Remainder: #set( $value = $foo % $bar )
