Showcase KOTUNES (Amiga Modplayer)


#1

A quick run with Kotlin and I really like it. Brings back a lot of fun in programming.

(There are still bugs in the rendering engine but you are welcome to fork on github)

A few things I figured:

  • Compile time seems to be slow (considering that my project has 10 files, 6sec is quite slow)
  • A lot of number type conversation is necessary(passing an int to a double parameter should be fine without toDouble()?)
  • Project creation wizard is not very comfortable. No initial setup is created (html, proper project structure, etc…)
  • Autocompletion often lacks all possible entries
  • Editor is more buggy than when working with Java (I had a hard time when trying to undo something which was just messing up more and more of my code)
  • Editor gets really slow when there are more than a handful errors (for instance when copy and pasting code from another language)
  • Exposed javascript code often looks a bit too complex and not straight forward (when using lambdas or loops).
  • Documentation lacks examples (try.kotlinlang.org > ‘kotlin in action’ has only chapter numbers - no hints of the content)

Nevertheless. I could manage to write this code within 2 days. Kotlin has a really nice learning curve and it is fun to write. We are considering it for the next version of www.audiotool.com

Thumbs down for the name though (just kidding, we are professionals) :slight_smile:

Compilation time greatly depends on your setup, e.i. cashing and incremental compilation. On JVM it is quite small.
