This week I reproduced a memory allocation strategy for audio buffers that I had previously made in Haxe - this time in D, making use of lower level constructs. It block-allocates buffers of variable sizes, with reference counting and some padding. It is not optimal on memory usage, but instead focuses on having all the processing data in one contiguous array for cache-friendliness purposes. The buffers may optionally describe an algorithm of "integer type and 16 floats and 16 ints as parameters." You can associate blocks into an entity and have the entity describe a list of blocks as a sequential program of "algorithm 1", "algorithm 2", etc. It's designed for very loosely defined usage - algorithms might be sharing a single buffer, copying between them, etc. The unit tests work, and I also got SDL audio output working with a sine wave test, so once I have some graphics rendering working and the buffers actually doing functional work, I will feel a little more confident about it.

This week will probably be about 2D graphics. I need a visualizer, and I'm feeling inspired to support sprites and text, at least at a basic level.

I guess I'm coding an engine at this point. This wasn't what I thought I was going to do when I started, but it actually lets me make the tooling all work together in a seamless design, which is Important To Me because it adds a lot of value.
