Require_relative / require in sonic pi

[brendanmac]

Hi
I too am new to Sonic Pi and Ruby, but certainly not a seasoned programmer. I can say that require does work in Sonic Pi, but cannot say if it is officially supported - require does not appear under Help/Lang. This thread is where I found out how to download and ‘install’ Ziffers, for example:

Ziffers - Numbered musical notation

Hi all! I wanted to share my new project called “Ziffers”: https://github.com/amiika/ziffers It is a new notation and parser for Sonic Pi that can be used to write, parse and play compact melodies. Its inspired by numbered musical notation. Basic syntax is composed of degree numbers 1 - 7 and lower letters w, h, q meaning w=whole, h=half, q=quarter … etc. For example “Bluebird song” can be played using Ziffers function: zplay q5353 5653 4242 4542 5353 5653 w5 q5432 w1 There is also suppor…

Then I just run

require "~/ziffers/ziffers.rb"

zplay "e 0 2 1 3 2 4 35"

and it works fine. Sadly I cannot answer your second more specific question re variables scope.
HTH
