Paul Tagliamonte a82564989e Add a position-independent digest of the AST (#2962) 
Each AST node contains an Option<Digest> which can be optionally set by running compute_digest() over the AST. This will mutate the AST and set the Digest. Fundamentally, the digest is computed from the digest of AST children nodes (using compute_digest) or the explicit raw underlying value.

The underlying hash is changeable by modifying the macro and Digest type alias, and should enable us to determine when an AST -- or fragment of AST -- is the same.

This won't hash the start/end of the AST fragment, so it's, to some extent, position independent. It will hash newlines, comments, etc, which may change in the future depending on how we wind up using this.

patternTransform A linear pattern on a 3D solid. manual

A linear pattern on a 3D solid.

Each repetition of the pattern can be transformed (e.g. scaled, translated, hidden, etc).

patternTransform(num_repetitions: u32, transform_function: FunctionParam, extrude_group_set: ExtrudeGroupSet) -> [ExtrudeGroup]

Examples

// Parameters
const r = 50 // base radius
const h = 10 // layer height
const t = 0.005 // taper factor [0-1)
// Defines how to modify each layer of the vase.
// Each replica is shifted up the Z axis, and has a smoothly-varying radius
fn transform = (replicaId) => {
  let scale = r * abs(1 - (t * replicaId)) * (5 + cos(replicaId / 8))
  return {
  translate: [0, 0, replicaId * 10],
  scale: [scale, scale, 0]
}
}
// Each layer is just a pretty thin cylinder.
fn layer = () => {
  return startSketchOn("XY")
  // or some other plane idk
  |> circle([0, 0], 1, %, $tag1)
  |> extrude(h, %)
}
// The vase is 100 layers tall.
// The 100 layers are replica of each other, with a slight transformation applied to each.
let vase = layer()
  |> patternTransform(100, transform, %)
