Once upon a time, there was Ink. Ink was a toy programming language, and I used it to build everything from personal productivity apps to compilers to ray tracers. Ink was wonderful, but had a handful of shortcomings and misfeatures that became more and more obvious over time as I used it.
Oak is a sequel to Ink that tries to correct many of these early mistakes, while being easier to read and use. Oak is intentionally not "Ink 2.0" — it's not a simple upgrade or bugfix, but a completely different language with quite different semantics and syntax.
In the meantime, if you're curious about the language, you can check out the Oak repository on GitHub, where you'll find more details about the language and a guide on how to try it today.
