Specification Overview

This page should provide a brief summary of the syntax of the language for you.

Functions

Forge defines functions in the same way as Elixir does. For example, here is a function that takes two numbers and adds them.

# add/2
def Add(a, b) do
  a + b
end

Note the automatic return of the result of the last statement evaluated. This is again the same as in Elixir.

Modules

Forge defines modules instead of the typical Class you might see in C++. Remember, Forge is a Functional language, so Modules act differently than classes as well.

defmodule Adder do
  def Add(a, b) do
    a + b
  end
end

Variable Types

Forge has the same types as Elixir, which also mirrors many other languages. A lot of the inspiration for the way Forge handles things can be seen here.

Integers

Integers are for storing non-floating point numbers.

x = 10

Floats

Floats are for storing floating point numbers.

x = 10.0

Booleans

Forge uses true and false for boolean values.

Atoms

Atoms are what most other variable types can be broken down into. Boolean values, for instance, are atoms.

$ fex> true == :true
true
$ fex> is_atom(false)
true

Strings

Strings are the same as in other languages, with the same syntax as Elixir: delimited by double quotes, and encoded using UTF-8.

iex> "hello"
hello
