Here is the first error:

Error[1,1]: not found: value Mw
Mw.hideAlgebraView()

The exception happens when we touch the canvas during Showcase/Tic Tac Toe (or Othello) instead of using the left mouse button to click. The good news is that it doesn't break the game. However, each touch event results in an exception and a long stack trace.

Note that touching the Run button on the script editor works OK.

Here is the log file:

Hi,

I attempted my first compilation and got an error:

[error] /Users/ben/src/kojo/git/kojo/src/main/scala/net/kogics/kojo/lite/MacTweaks.scala:25: type mismatch;
[error]  found   : com.apple.eawt.AboutHandler
[error]  required: java.awt.desktop.AboutHandler
[error]     app.setAboutHandler(new AboutHandler {

Here is the version of java I have:

Thanks so much,

"To get access to builtins in a test, the best way is to probably build up a stub code execution context."

We would like to provide a basic test that uses builtins (assuming no such test already exists.) So that we could test many commands that depend on builtins. e.g. epochTime.

At the moment, calling any such command results in a runtime error (compiler is not able to catch this problem):

I know this probably isn't an easy one to do, but, it may be worthwhile. The most important subset of intellisense I think, is the ability to look up documentation within the editor for given types, functions, etc.

Had to reboot the macbook. No key or key combo worked. Esc, Cmd-Tab, Cmd-Ctr-F.

The code that's the culprit is rather simple (see below).

It worked fine until I switched to full screen and then back, turned on the axes (not sure that's relevant, but just to capture the sequence of events. I will write again after root-causing this), turned the axes off again and the keys (defined below) stopped working. I then switch it to full screen using the context menu (stupid thing to do, but, that's hindsight for you :-) and got stuck. Now that I captured this so far, let me try to reproduce it. Wish me luck.

onKeyPress {
    case 90 => { // pressed z
        removeLastPoint()
        println(points.size + " points now")
    }
    case 67 => { // pressed c
        if (emptyStack()) { println("stack empty now") }
        else {
            val oldPoint = popFromStack()
            points.append(oldPoint)
            println(s"${points.size}")
            if (points.size > 2) {
                drawTriangles()
            }
        }
    }
    case 88 => { // pressed x
        while (!emptyStack) removedPoints.pop
        println("empty")
    }
    case a => println(s"$a")
}

when running the following simple code, an error occurs. My system is win10.

import io.StdIn
val r = StdIn.readInt

//#yükle tr/sozcuk-dizinini-yukle
cleari
val dict: List[String] = sözcükDizininiYükle
val wrong = dict(2)
val right = "abacı" // "ı" is a Turkish char
println(wrong)
write(wrong)

This is used in the anagram sample. It works in MacOS builds, but fails on Windows machines.

Would it make sense to enhance Kojo to support modular scripting features in ammonite like import $file, $exec and $ivy?

Is there an alternative available to use now for modular development of bigger scripts in Kojo?

In Turkish, a simple example from the scala tutorial is:

val n = new Nokta(3, 4) //> val n: Nokta = Nokta@98f03a4
n.x //> val res1: TurkishAPI.Sayı = 3

It would help readability to remove TurkishAPI. and return only the type alias (type Sayı = Int and Nokta is Turkish for Point) as follows:
p.x //> val res1: Sayı

I hope this is not too involved? Either way, please let me know a few pointers and I can work on it..

Here is a sample:

clearOutput
val big= 200_000_000
println(big / 100_000.0)

This code compiles and runs. However, when we run "Format Source" command, we get an error:
Unable to format: Invalid literal number: _
and the formatter fails to format the code.

Running a script as a worksheet attempts to interpret multi-line comments. E.g.,

val x = 3/2 //> val x: Int = 1
/*
 y //> error: not found: value y
 */
val z = List(1,2,3)

Please advise what I can try to avoid this installation error (maybe I need to contact Install4J developers?):

Right clicking with the mouse (tapping with two fingers on the touch pad) on any color or numerical value in the code editor lets us manipulate drawings on canvas interactively. E.g.,

// Click on yellow with right mouse button to bring up color editor:
val c = yellow

Please enhance the code to support the local language. E.g., in Turkish, we have:

val c = sarı

Thank you so much!
B

Below is a sample. The REPL result for the code val x = 3 is appended at the end of the first multi-line comment.

/*
 *           [b]
 *          /  \
 *        [a]  c,20
 *       /  \
 *     a,30  b,10       
 */      //> val x: Int = 3

/* what's going on? */
 
val x = 3

It gets stuck at the splash screen (displaying the circle of colorful squares and the text: Loading...) and Kojo never starts up.

Version: 2.9.22

Tried on two machines:

1. MacBook Pro laptop running macOS Monterey Version 12.5 and
2. MacBook Air running macOS Catalina Version 10.15.7

My own build from the latest comes up fine on machine (1).

I don't see anything at: https://bitbucket.org/lalit_pant/kojo/wiki/Kojo%20Localization

I do fantasize about making this available in Turkish..

Here we can discuss things to add related to the Chess project.
