NYAA-PL (Not Yet Another Abstracted Programming Language)

Introduction

NYAA-PL is a tree-walk interpreted programming language developed in Python (because why not :P),
created for fun and exploration in the realms of language and compiler design. Inspired by
anime, memes and the japanese language (borrowed and native words) references, this isn't
intended for real-world use.

Getting Started

Prerequisites

• Python 3.10 🐍

Features

Built-ins

• yomu: print line to console

  yomu("Hello, World!")

• ohayo: get input from user

  name = ohayo("Enter name: ")

Variables

name = "NYAA"
age = 1000
pi = 3.142

yomu(name)
yomu(age)
yomu(pi)

Output

NYAA
1000
3.142

Conditionals

• if Statement

  # If statement
  nani ( expression ) { body }
  
  # If-else statement
  nani ( expression ) { body }
  baka { body }
  
  # If-elif statement
  nani ( expression ) { body }
  nandesuka ( expression ) { body }
  
  # If-elif-else statement
  nani ( expression ) { body }
  nandesuka ( expression ) { body }
  baka { body }

• Loops

  # While loop
  daijoubu ( expression ) { body }
  
  # For loop
  # '_' can be used in the same way as a variable within the for loop
  for _ => ( start, end ) { body }
  for i => ( start, end ) { body }

Functions

• Defining a function

  Functions are defined before the program (main) block

  # One line function
  kawaii func_name(param1, param2, ...) => statement 
  
  # Multi-line function
  kawaii func_name(param1, param2, ...) => { body } 

• Calling a function

  kawaii add(x, y) => {
    # return x + y 
    modoru x + y
  }
  
  uWu_nyaa() => {
    result = add(1, 1)
  }

Code Examples

Hello_World.ny (single statement body)

# program block  
uWu_nyaa() => yomu("Hello, world!");  

Greet.ny

# function definition  
kawaii greet(name) {
	yomu("Hello,", name)
}  
  
# program block  
uWu_nyaa() => {  
	# Get input from user and assign it to name
	name = ohayo("Enter name: ") 
	greet(name)
 }
