About

This is just a small test project

Requirements

This project requires python3 and makes use of the standard library. For testing purposes you will need GNU Make and BATS

A shell.nix file is included to create a quick testing environment with nix on both Linux or MACOS. Else, you can follow the instructions as below.

MACOS

Python 3 is still shipped with the latest version at the moment of writing (11.5) Else you might use homebrew or nix to install it.

# Homebrew
brew install python@3 make

# nix
nix -iA nixpkgs.python3 nixpkgs.make

Linux

Most standard linux distributions will ship python 3. If this is not installed, you can install it using your package manager

# apt
sudo apt install python3 make

# Yum
sudo yum install python3 make

# emerge
sudo emerge --ask dev-lang/python:3.8

# nix
nix -iA nixpkgs.python3 make

Running

Just executing the script will return a randomized range of numbers from 1 to 10, a couple of bonus features are added:

  • Specify the ammount of numbers to be returned
  • Specify the start of the range
  • Return the ordered range instead of a random one
./number-printer.py -h

# usage: number-printer.py [-h] [-o] [-s START] [ammount]

# Generate a range of random integers

# positional arguments:
#   ammount               Specify the ammount of digits to return

# optional arguments:
#   -h, --help            show this help message and exit
#   -o, --ordered         Returns an ordered range
#   -s START, --start START
#                         Specify the start of the range
./number-printer.py

Testing

Basic testing is acomplished with BATS. A basic Makefile servers as a helper.

nix-shell --run "make test"

# Or if dependencies where manually installed
make test
