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}

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}
