I just discovered this amazing editor! But on on OS 3.1 pressing an arrow key on the editor page causes it to crash with error, "attempt to call a boolean value." I was able to fix it by deleting this part:

Code: [Select]

--disable specific arrow key events (to trigger the on.arrowKey(direction) event)
on.arrowUp=false
on.arrowDown=false
on.arrowRight=false
on.arrowLeft=false


And that's great timing because I was about to release v2.2.1 this week, which also fixes some problems on the newer OS, so I'll also include a fix for that problem! Seems like the event caller was a bit dumb on OS 3.1    While your fix may work on OS3.1 (can't test it my self), it doesn't work on OS3.2+, but I found a different solution (make the event distributor (on's metatable) return nil when the event is one of the arrow key events)

Hi Jens_K! You've made a really great script editor! Everything that I needed to know was either in the readme, self-explanatory, or understood through trial-and-error. I just can't figure out one thing; How do you run a script? I get that you have to press MENU > Code > Run, but I switch to the Run page and can't figure out what I'm doing! It says Click to run, but I click the center button, and nothing happens. Sometimes it returns an error that won't solve (even when pressing Menu and trying to let the editor solve the error). I'm on a Clickpad running OS 3.6, if that makes any difference at all.

Hi Jens, another issue I'm having: I'm trying to run a script with several parts. I can't seem to run this code, it always takes extremely long, presumably forever, to load page 1.2:

Code: [Select]

while true do
  function on.paint(gc)
    function textDisp(x,y,str)
      gc:drawString(str,x,y)
    end
  end
  platform.window.invalidate()
end
I've tested that whole code block without the while block, yet it doesn't work with the while. Is there a problem with my code? Or could it be the editor?

Nspire Lua programs have a different structure, they are event based; code outside of event handlers is usually only executed at the programs start and only for initialisation, which in your case takes an infinite amount of time due to your while loop, which is why your program doesn't respond.
You can see the available events in the Nspire API guide (on page 2.1).
To do what you wanted to do, you could use the timer to refresh the screen repeatingly:

Code: [Select]

x = 0
timer.start(0.01)
function on.timer()
  x = x + 1
  --update screen
  platform.window:invalidate()
end


function on.paint(gc)
  gc:drawString("hi", x % 300, 20)
end
But you don't have to update the screen repeatingly, whenever the Nspire forgets the screens content, it asks for an update by calling on.paint.
