Documentation for % and the |> tokens?

[olatheander]

Hi,

I've played around with the modeler after listening to the episode in Developer Voices. I did a honest try browsing the docs for the KCL language but I can find a clear definition of what's the meaning of the % and the |> tokens?

E.g. in a KCL like:

  |> startProfileAt([0, 0], %)

What does it mean to start a line with |> and what does the % mean?

[jtran]

a
  |> b(%)
  |> c(%)

is the same as

c(b(a))

The % indicates where to substitute the previous value. So

  |> startProfileAt([0, 0], %)

uses the result from the previous line (probably a plane) as the second argument to startProfileAt.

Hi, thanks for the clarification. However, maybe I just did look at the wrong place but I could not find it documented.

I mostly looked here: https://zoo.dev/docs/kcl
