What I do is to simply write a few modify. For sake of completeness, here is a very simple/pragmatic solution for this case: However with a low level of nesting, I sometimes feel lenses are a bit too much, and I don't want to introduce the whole lenses approach if there is only few places with nested updates. Note that Kiama steps outside the type system to achieve this.ĭue to their composable nature, lenses provide a very nice solution to the problem of heavily nested structures. Here's a snippet to whet your appetite: // Test expression Kiama supports Rewriting, see the examples in RewriterTests, and watch this video. The classical example is transforming an AST for a language, perhaps to evaluate, simplify, or collect information. In other circumstances, you might like to apply some transformation across the entire data structure, according to some strategy (top-down, bottom-up), and based on rules that match against the value at some point in the structure. Doesn't look like he used the modified compiler, though, as I can't see any annotations. Incidentally, Lukas recently published a version of Pacman, user programmable through a DSL. So the community needs to persuade the Scala team that this effort should be continued and integrated into the compiler. Using the compiler-generated location classes this gets much easier: Scala> val g2 = g1.copy(pacman = g1.py(superMode = true)) However, changing pacman's super mode is much more cumbersome (and it gets worse for deeper structures): ![]() ![]() Changing the game state to "run" is simple using the copy method: Scala> case class Game(state: String = "pause", pacman: Pacman = Pacman()) I'll reproduce his example here: scala> case class Pacman(lives: Int = 3, superMode: Boolean = false) It turns out that the structure of the zipper is automatically derivable from the original data structure, in a manner that resembles symbolic differentiation of an algebraic expression.īut how does this help you with your Scala case classes? Well, Lukas Rytz recently prototyped an extension to scalac that would automatically create zippers for annotated case classes. Scalaz provides Zippers for Stream ( scalaz.Zipper), and Tree ( scalaz.TreeLoc). ![]() Huet's Zipper provides convenient traversal and 'mutation' of an immutable data structure. ![]()
