Panther Variables

Syntax

  Variables in Panther are a mechanism to give a specific value a name. They can be declared in global scope or in local function scope. Syntax 1 creates an explicitly typed variable whereas syntax 2 creates an implicitly typed variable.

Var Variables

  Var variables are values that have storage and are mutable. The assignment value may be an initializer value. The value category of def variables is concrete-mutable.

Const Variables

  Const variables are values that have storage and are not mutable. The assignment value may be an initializer value. The value category of def variables is concrete-const.

Def Variables

  Const variables are values that do not have storage and are not mutable. The assignment value must be constexpr and it may be an initializer value. The value category of def variables is ephemeral. If declared without an explicit type and with an assignment value that is fluid, the def variable is fluid.

Variable Attributes

#pub

Make the variable accessable outside this module (such as through intrinsic @import)

Examples:

1
2
3
4
5
var var_variable: Int = 12; // var variable
const const_variable = true; // const variable that's implicitly-typed

def DEF_VARIABLE: Int #pub = 12; // def variable with the `#pub` attribute
def DEF_VARIABLE_FLUID = 12; // def variable that's fluid
