#[[ 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")
|
||||
|
||||
#macro( tablerows $color $somelist )
|
||||
#foreach( $something in $somelist )
|
||||
<tr><td bgcolor=$color>$something</td></tr>
|
||||
#end
|
||||
#end
|
||||
|
||||
#tablerows("red" ["dadsdf","dsa"])
|
||||
|
||||
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 )
