Get java.util.concurrent.CancellationException with org.creativescala::doodle:0.24.0 #176

Open dacr opened 1 month ago

dacr commented 1 month ago

The following script executed using scala-cli 1.4.0 : 

//> using scala "3.4.2"
//> using dep "org.creativescala::doodle:0.24.0"

import doodle.image.*
import doodle.core.*
import doodle.syntax.*
import doodle.image.syntax.*
import doodle.syntax.all.*
import doodle.image.syntax.all.*
import doodle.java2d.*
import cats.effect.unsafe.implicits.global

val circle = Image.circle(500).noFill.strokeWidth(2)

val count=50
val circles = {
  1.to(count)
    .map(_.toDouble)
    .map(f => circle.transform(Transform.translate(500d,0d)).scale(f / count, f / count))
    .reduce((i1, i2) => i1.on(i2))
}

circles.draw()

works well with doodle:0.23.0 but crashes with doodle:0.24.0. (I can briefly see the window during less than 1 second)

Thanks. I'll look into it.

noelwelsh commented 1 month ago

Alright, I think I've fixed it. I'm not going to close this report immediately, as there might still be issues. I'll make a release soon to allow further testing.

noelwelsh commented 1 month ago

v0.25.0 will be out as soon as CI has finished.

dacr commented 1 month ago

:) Fixed for the two examples I have just tried.

There is probably other issues (although not sure at 100%), for example with this animated script is frozen :
