On Writing a Sane API

Over my years on the ComputerCraft Discord server, I've had the opportunity to witness the creation of numerous APIs/libraries of all sorts. I've gotten to examine these APIs in depth, as well as answer questions involving the APIs that the creators or users have. As an API designer myself, I compare the designs of other APIs with my designs, and I've noticed a number of patterns that make or break an API design. I've seen plenty of designs that make me go "WTF???", and lots that I just can't understand, even at my advanced level of programming (not to toot my own horn).

This article outlines some rules for making a sane API, which is easy to use, understandable, and doesn't make the user spin in circles to make things with it. Note that when I use the term "API", I'm primarily referring to code libraries and their public interfaces, but a number of points can be applied to web APIs as well. Since I have the most experience in Lua APIs, I'll be focu

WAV format for DFPWM data

This document describes how to store DFPWM data in a WAV file.

Overview

DFPWM data is specified through the WAVE_FORMAT_EXTENDED data type, with the UUID 3ac1fa38-811d-4361-a40d-ce53ca607cd1. Channels are stored interleaved, and samples are packed in groups of 8 per byte, as is consistent with raw DFPWM data. Only DFPWM1a data is considered here - original DFPWM should not be stored using this UUID.

fmt  chunk

The fmt  chunk follows the standard layout for WAVE_FORMAT_EXTENDED, using the assigned DFPWM UUID:

| Offset | Bytes | Description |
