Ducktype 1.0

2019-04-13

Earlier this week, I released the final specification for Ducktype 1.0. If you’d like a quick primer on what Ducktype looks like, check out our Learn Ducktype tutorial.

Ducktype is a lightweight syntax designed to be able to do everything Mallard can do. It doesn’t sacrifice semantics. It doesn’t sacrifice metadata. It doesn’t sacrifice nesting and content model.

It took a long time to reach 1.0, because I take compatibility and correctness very seriously. Syntax is API. I work with multiple documentation formats on an almost daily basis. It is frustrating to constantly run into language quirks, especially quirks that vary between implementations. I realize quirks tend to accumulate over time, but I think we’ve prevented¬† a lot of them by writing an actual specification, developing a regression test suite, and focusing on the cohesiveness of the language.

I’m really happy with how it’s turned out so far. I hope you enjoy it too.
