There are lots of tools that type designers need that don't yet exist. We don't have any source control systems, we don't have a sophisticated proofing tool, our drawing tools haven't really advanced since 1987, etc. I don't have time to build all the tools we need. Heck, I don't want to build all the tools we need. So, here we are. I'm making the building blocks that I use to create my software available to you. Maybe this will help someone, somewhere get a head start on producing the next great, useful tool.
Everything from my core font objects, to the fast glyph cell view, to the OpenType layout engine and more. I've even made source code for Area51 available as a demonstration of how I like to build things.
How do I get it?
It's all available in my source code repository, which you can find at code.typesupply.com.
What's the catch?
There is no catch. The code in the repository is available under the MIT license so you can do pretty much whatever you want with it.
