And am extremely confused with some of new syntax. So if I have a enum with a case X I can't simply add a method for a specific case by just doing

enum AST
case Str(v : String) {
def newMethodIWantHere...
}

Seems very weird. Probably doing something wrong again 🤔😮‍💨

@vascorsd This had me stumped for a long time, too! Here is how I think you're supposed to do it:

enum AST:  
 case Str(v: String)  
 case Num(i: Int)

object AST:  
 object Str:  
 extension (s: Str)  
 def foo: String = "value: " + s.v

AST.Str("Hello").foo  
// AST.Num(0).foo // Does not compile

For Americans looking at people posting in Celsius temperatures: don't try to convert, just remember this...

Zero is freezing,
Ten is not.
Twenty is warm and
Thirty is hot
(And forty is DAMNED hot)

@realtegan Nice! Do you have one of those for Celsius users with no intuition for Fahrenheit? 😅

Indigo 0.17.0 released, with a host of improvements and fixes. 🕹️

Progress! Window's now cascade their bounds to their content model, and if their content model is a component group then the new layout is configurably cascaded through the component tree. It's all rather crude, but should be useful nonetheless.

After a solid month or two of engine improvements, my little ASCII paint app looks like it did before! 💪
However, all the UI stuff now runs in a subsystem and all the layers are nested under one key, making the app logic far, far simpler. New Indigo release coming soon...

There are some really great coders who don’t get and that’s OK but I wish they would not use that misunderstanding to just proclaim that it is useless. On the other hand we need to find a way to prove the usefulness without just saying that “you are holding it wrong”.

@matadan I'm not disagreeing with you, truthfully, I just find the lack of nuance and empathy in the age old TDD debate frustrating.

TDD has great value in the right situation, as do other approaches.

Let there be window content!

Slightly bizarre moment when I realised I could just embed the Elm arch inside the Elm arch to make all this work. So the window contents are miniature Indigo games.

(This is all #Scala 3 with @scala_js, btw.)
