Create a live template with variables and functions
In this tutorial, you will learn how to create and use a simple live template that includes variables and functions.
To showcase how variables and functions work in templates, we will add the following variables to the template text:
$animal$: an empty one for the users to type a value$food$: a list of three possible values: "meat", "fish", and "grass"

ins_animals.In the Template text field, paste the following template:
type $TypeName$ struct { food string } func (p *$TypeName$) PetFood() { food := "$Food$" println("The $typeName$ eats " + food) }insert into animals (animal, food) values ('$animal$', '$food$'$END$);Click Edit Variables and, in the Edit Template Variables dialog, configure the variables:
$animal$remains untouched meaning we expect users to type a value when they apply this template.$food$: in the Expression field, enterenum("meat","fish","grass"). This function allows selecting one of the predefined values when users apply this template.
