Switch / Case / Default

A switch statement checks the source and compares it against several declared patterns. It then executes the first case pattern that resolves to true. or a default one if nothing resolves to true (and default is provided).

A switch statement is equivalent to chaining multiple if statements one after another.

Syntax

Basic syntax of switch tag is as follows:

{[ switch [statement] ]}
   {[ case 1 ]}
   Executes when statement equals 1
{[/]}

You can chain as many cases one after another:

{[ switch [statement] ]}
   {[ case 1 ]}
   Executes when statement equals 1
   {[ case 2 ]}
   Executes when statement equals 2
   {[ case 3 ]}
   Executes when statement equals 3
{[/]}

Additionally, compared to strongly typed languages, you can check against multiple data types at the same time:

{[ switch [statement] ]}
   {[ case 1 ]}
   Executes when statement equals 1
   {[ case true ]}
   Executes when statement equals 2
   {[ case "Some text" ]}
   Executes when statement equals 3
{[/]}

Default fallback

Additionally, you can use default case to fallback to it when all other cases fail. Default case is optional:

{[ switch [statement] ]}
   {[ case 1 ]}
   Executes when statement equals 1
   {[ case 2 ]}
   Executes when statement equals 2
   {[ default ]}
   Executes when statement equals to anything other than 1 or 2
{[/]}
