Tii Class #

Tii represents Function class in Mosc. It’s first class function — an object that wraps an executable chunk of code. Here is a friendly introduction.

Static Methods #

kura(fun) #

Creates a new function from… fun. Of course, fun is already a function, so this really just returns the argument. It exists mainly to let you create a “bare” function when you don’t want to immediately pass it as a block argument to some other method.

nin fn = Tii.kura {
  A.yira("The body")
}

It is a runtime error if fun is not a function.

Methods #

arity #

The number of arguments the function requires.

A.yira(Tii.kura {}.arity)             # > 0
A.yira(Tii.kura {(a, b, c) => a }.arity) # > 3

weele(args…) #

Invokes the function with the given arguments.

nin fn = Tii.kura { (arg) =>
  A.yira(arg)     # > Hello world
}

fn.weele("Hello world")

It is a runtime error if the number of arguments given is less than the arity of the function. If more arguments are given than the function’s arity they are ignored.
