Noot lang

A simple scripting language, created specifically for NootBot.

Hello World

// helloWorld.noot

noot!("Hello World")

Description

Nootlang is a simple scripting language mainly developed for NootBot. The interpreter and parser are intentionally kept simple and readable as it is also developed as a learning project. Anyone interested in making programming languages or parsers and interpreters in general should be able to understand the code rather easily. The interpreter is therefore focussed on readability rather than speed.

Roadmap

• Types
  • integers
  • strings
  • floats
  • booleans
  • functions
  • anonymous functions

  def myFunc() {}
  def myOtherFunc(fn) { fn() }
  myOtherFunc(myFunc)
  myOtherFunc(|| {})
  

  • structs
  • interfaces
  • tuples
  • type assertion
• Functions
  • functions
  • scopes
• modules
• Statements
  • if/elsif/else
  • match

Native Function Interface

Native functions (like the ones in the standard library), are of the following signature:

func(*runtime.Runtime, args []interface{}) (interface{}, error)

• The first argument passed to any function is always the runtime, this contains all the variables and functions available.

• The second is an array of all the arguments passed to this function

• The function can return a value as its first return type, or nil if it does not return a value

• If a runtime error occurs during execution, the function should return a descriptive error as its second argument

Contributing

Contributions are always welcome.

• Additions (e.g. new syntax, etc.) to the language should be discussed first in an issue befoe submitting a pull request
• Speed improvements to the interpreter, parser or tokenizer will be accepted as long as they do not compromise on readability. The focus of this project lies in readability for newcomers.
• However, if you are passionate about making a fast interpreter for nootlang, this is encouraged. Just make a new folder in this project for the faster interpreter so that they are separated. Here, readability can be compromised for speed (JIT compilation, caching, etc.)
• Documentation is highly needed at the moment
