README.md

mathgen, or why I'm so so sorry

Go's type system is a double-edged sword, and the inner edge will definitely get you when you go to do generic math. I opted against using the reflect library, and instead went for codegen. So while the result is barely readable, it will at least be somewhat faster, theoretically.

This module generates the math.go file which resides in the core library. The mathgen.tpl file is where most of the magic happens. It is virtually unreadable. The biggest reason for this is that I want it to be able to pass through go fmt unphased, so that it doesn't end up getting changed back and forth throughout the code's history.

Running

You can run code gen by running make gen in the core/ directory. The Makefile in the root of the project should also reference this, so running that in the root should also result in the file getting regenerated.
