Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2020-02-21T18:39:05+00:00 2020-02-21T18:39:05+00:00 Tim Foley tfoleyNV@users.noreply.github.com 2020-02-21T18:39:05+00:00 urn:sha1:830671c2210191f69ddc403cc12f5454bb55b0f0 Within the context of an aggregate type (or an `extension` of one), the programmer can use `this` to refer to the "current" instance of the surrounding type, but there is no easy way to utter the name of the type itself. This is especially relevant inside of an `interface`, where the type of `this` isn't actually the `interface` type, but rather a placeholder for the as-yet-unknown concrete type that will implement the interface. This change adds a keyword `This` that works similarly to `this`, but names the current *type* instead of the current instance. It can be used to declare things like binary methods or factory functions in an interface: ``` interface IBasicMathType { This absoluteValue(); This sumWith(This left); } T doSomeMath<T:IBasicMathType>(T value) { return value.sumWith(value.absoluteValue()); } ``` The `This` type is consistent with the type named `Self` in Rust and Swift (where Rust/Swift use `self` instead of `this`). Other names could be considered (e.g., `ThisType`) if we find that users don't like the name in this change.
