# Nom

Nom lang is a dynamically typed lightweight functional language focusing on simplicity and embeddability.It is currently dynamically scoped, but lexical scope is being worked on. At the moment automatic memory managment is limited to reference counting, so avoid circular references. The Standard Library is currently being implemented, and not all functionality is there.

## Install

To install on linux, run the install.sh script. Any program you make will require you to type "nom program_name" or just add #!/usr/bin/nom to the beginning of the scripts to specify which interpreter to use. REPL isn't well tested. Examples are in tests folder.

Example factorial program written in Nom:

    var factorial = function(n):

      if n <= 1:

        return n

      end

      else:

        return n * factorial(n-1)

      end

    end

    

    var f = factorial(5)

    print(f)

## Nom vm

Nom runs on a stack based virual machine, and nom code is compiled to nom bytecode before it is executed in the vm, so technically it could be adapted to be a compiled language, but for now it is interpreted.

## Basic usage

A codeblock starts with a colon and ends with an end statement. This is used for everything that would require a codeblock, eg: conditionals, loops, functions.

One line comments can be used with "#"

If, else if and else statements

    if condition:

        #Do something

    end

    elseif condition:

        #Do something else

    end

    else:

        #DO something else

    end

Loops

  

    while condition:

        #do this

    end

    for var i=start, i
