Free/open-source softwareTidal Cycles (or 'Tidal' for short) is a free/open source live coding environment for algorithmic patterns, written in Haskell. Tidal is using SuperCollider, another open-source software, for synthesis and I/O. Pattern everythingTidal Cycles allows you to make patterns with code. It includes language for describing flexible (e.g. polyphonic, polyrhythmic, generative) seque
struct User { let name: String let age: Int } // birthday(user: User(name: "Anton", age: 33)) = User(name: "Anton", age: 34) func birthday(user: User) -> User { // Calls Haskell function... } To support this workflow, we need a way to convert the User datatype from Haskell to Swift, and vice versa. We are going to serialize (most) inputs and outputs of a function. Even though the serialization as
Tacit programming, also called point-free style, is a programming paradigm in which function definitions do not identify the arguments (or "points") on which they operate. Instead the definitions merely compose other functions, among which are combinators that manipulate the arguments. Tacit programming is of theoretical interest, because the strict use of composition results in programs that are
From my perspective, one of the biggest open problems in implementing programming languages is how to add a type system to the language without significantly complicating the implementation. For example, in my tutorial Fall-from-Grace implementation the type checker logic accounts for over half of the code. In the following lines of code report I’ve highlighted the modules responsible for type-che
Why is Prettier rock solid?I've always wondered why Prettier is so good. Yes, it learnt from gofmt what to do (note that gofmt doesn't indent, which is the hard part). Yes, it was announced in a real life conference, which helped get the initial momentum behind it. All that is fine, but what was a bit inexplicable to me is its quality. You might disagree with the defaults (I like them. The only on
