Template Operators
Operators are symbols that allow you to compare two values or combine two values.
Comparison Operators
Many times you whether in using a ternary condition or in conditional rendering you'll want to use a comparison operator. This page documents what is available to you in the component studio templating language. These operators will return 1 if true or 0 if false.
Operator  Description  Example 
==  Equal to. Note that = is not the same thing. 
{$quantity == 5}
{$color == 'blue'} 
!=  Not equal to. 
{$quantity != 5}
{$color != 'blue'} 
>  Greater than.  {$quantity > 2} 
<  Less than.  {$quantity < 2} 
>=  Greater than or equal to.  {$quantity >= 2} 
<=  Less than or equal to.  {$quantity <= 2} 
? :  Ternary condition. It takes 3 arguments. The first is the condition to validate, then the true value, and then the false value. 
Arithmetic Operators
Perform a mathematical calculation upon two values.
Operator  Description  Example  Result 
+  Addition  {1 + 1}  2 
  Subtraction  {1  1}  0 
*  Multiplication  {1 * 1}  1 
/  Division  {1 / 1}  0 
%  Modulus, the remainder after division. 
{1 % 1}
{5 % 3} 
1
2 
min  The smaller of the two numbers.  {20 min 40}  20 
max  The larger of the two numbers.  {20 max 40}  40 
Logical Operators
Perform logic operations on values to determine a true or false value.
Operator  Description  Example  Result 
!  Not. Invalidates the value. 
{!1}
{! 3 < 1} 
0
1 
&&  And. 
{0 && 0}
{1 && 0} {1 && 1} { 3 > 1 && 1 > 0} 
0
0 1 1 
  Or. 
{0  0}
{1  0} {1  1} { 3 > 1  1 > 0} 
0
1 1 1 
//  Default. If the original is undefined, then use this. 
{$something_empty // 'blue'}
{$color_is_orange // 'blue'} 
blue
orange 
or  Or. Same as  


not  Not. Same as !  
and  And. Same as &&  
? : 
Ternary. It takes 3 arguments. The first is the condition to validate, then the true value, and then the false value.  {$position == 'king' ? 'purple' : 'white'}  purple 
String Operators
Use the to manipulate strings.
Operator  Description  Example  Result 
~  Concatenate. Combines two strings together. 
{'R' ~ 'G' ~ 'B'}
{$first_name ~ ' ' ~ $last_name} 
RGB

Nil
When you are trying to check for a field that is undefined or empty, then you'll want to use the special keyword 'nil'. For example, if you have a field that might be empty and you don't want to render it when empty, you could add this to conditional rendering to do this:
{$this_might_be_empty == nil}
