numlang-9ee9

A very concise language for processing numbers.

Introduction

Numlang is a golfing language designed for handling integers, and lists of integers.

9ee9 is the alternative name for Numlang. It is taken by converting num from Base 64 to Hexadecimal.

Setup and running the code

Installation

Install numlang-9ee9 from PyPI:

$ pip install numlang-9ee9

Running the code

To run your code, use the numlang command, followed by your code in quotes:

$ numlang "#Fx"

Tutorial

Basics

Numlang has 5 variables: x, y, i, l, and n. You cannot define your own.

x and y are the input variables (discussed in the User Inputs section)

i is the iterating variable (discussed in the Loops section)

l is a list which starts as []. You can use methods on it (discussed in the Methods section)

n is an integer which starts as 0. You can perform operations on it (discussed in the Operations section)

The output of the last operation performed is always outputted at the end of the program in Numlang.

User Inputs

Integer

To get a single integer as an input, use #. The input will be converted to an integer, and implicitly stored in the x variable

An example program is #+1. It will take the input from the user, add one, and output it.

List

To get a list of integers as an input, use $. The input must be integers separated by spaces, like 1 2 3 4.

All elements will be converted to integers. The list will be implicitly stored in the y variable.

An example program is $;{i+1}. It will go through the list, add one, and output it.

Loops

To loop, add the iterable, then any code you want to loop in braces. Each time it loops, the next element of the iterable is implicitly assigned to the i variable.

An example program is #Rx;{i*2}. It will go through each number from 0 to the input minus one, and multiply by 2.

Note: the closing bracket is unneccesarry if it is at the end. The interpreter will automatically put it in.

Methods

Range

R is the Numlang equivalent of range in Python. You can use Rn; to get the numbers from 0 to n.

Append

To append to a list, use A. Use yAi; to append i to y.

Without

Use W to exclude all instances of an element from a list. Use lWx; to remove all xs from l.

Sort

Use S to sort a list. Use lS to sort l.

Deduplicate

To remove duplicates, use D. Use lD to deduplicate l.

Is Prime

Use P to test if a number is prime. Use it as a function: P(i). No semicolon needed.

Primes

Use R to get prime numbers. Use Ri; to get the first i primes.

Mersenne primes

Use M to get Mersenne primes. Use Mi; to get the first i Mersenne primes.

GCD

The G method is for getting the GCD of a list of numbers. Use Gl; to get the GCD of all the elements of l.

LCM

The C method is for getting the LCM of a list of numbers. Use Cl; to get the GCD of all the elements of l.

Operations

You can use the following operations in Numlang:

+ (addition) - e.g. i+x;
- (subtraction) - e.g. i-x;
* (multiplication) - e.g. i*x;
/ (integer division / floor division) - e.g. i/x;
^ (exponentiation / power) - e.g. i^x;
% (modulus / remainder) - e.g. i%x;

Conditions

In Numlang conditions take the form ?cond;if_true;.

An example program is #R100;{?i%x;i;}. It will go through the numbers from 0 to 99, and print those which are multiples of the user input.
