Adds an `arrayReduce` function to KCL stdlib. Right now, it can only reduce SketchGroup values because my implementation of higher-order KCL functions sucks. But we will generalize it in the future to be able to reduce any type.
This simplifies sketching polygons, e.g.
```
fn decagon = (radius) => {
let step = (1/10) * tau()
let sketch = startSketchAt([
(cos(0) * radius),
(sin(0) * radius),
])
return arrayReduce([1..10], sketch, (i, sg) => {
let x = cos(step * i) * radius
let y = sin(step * i) * radius
return lineTo([x, y], sg)
})
}
```

|
||
|
||
Take a starting value. Then, for each element of an array, calculate the next value,
|
||
|
||
using the previous value and the element.
|
||
|
||
```js
|
||
arrayReduce(array: [u64], start: SketchGroup, reduce_fn: FunctionParam) -> SketchGroup
|
||
```
|
||
|
||
### Examples
|
||
|
||
```js
|
||
fn decagon = (radius) => {
|
||
let step = 1 / 10 * tau()
|
||
let sketch = startSketchAt([cos(0) * radius, sin(0) * radius])
|
||
return arrayReduce([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], sketch, (i, sg) => {
|
||
let x = cos(step * i) * radius
|
||
let y = sin(step * i) * radius
|
||
return lineTo([x, y], sg)
|
||
})
|
||
}
|
||
decagon(5.0)
|
||
|> close(%)
|
||
```
|
||
|
||
|
||
|
||
### Arguments
|
||
|
||
* `array`: `[u64]` (REQUIRED)
|
||
* `start`: `SketchGroup` - A sketch group is a collection of paths. (REQUIRED)
