Bump! Added a save file dialog! You Nspire-owners should test it out...

Nice :)

Feedback : print("hello") gets in the tns as :    print(%22hello%22)  so it errors   :P

Actually maybe this has been done already. So now you might want to poke me about infinite loop support.

Btw Juju, on the source code, I see at https://github.com/juju2143/LuaIDE/blob/master/luna.php#L10 :
Code: [Select]

Do you check/sanitize/whatever the input ?

It wouldn't be good if the php process were to execute some things like "shell_exec('luna '. 'test.lua' . ' ' . 'test.tns ; rm -Rf /');" :D

Yes, actually at line 2 and 3 PHP generate a random filename (something like /tmp/lunaAsdfasdf), so there's no chance the user could put a rm -rf / in there. Then at line 14 a header with an actual file name is sent (which have no incidence on the filesystem).

Well. After the The Fun Has Been Doubled Update, (yeah, codenaming updates sure is fun, I should do that more often) we now have the long-awaited... The Infinite Loop Update!

That is, infinite loops work! Try it out with this sample code:

Code: [Select]
i = 0
zmg.clear()
while true do
zmg.drawText(0,0,i,zmg.makeColor("black"),zmg.makeColor("white"))
zmg.fastCopy()
time = zmg.ticks()
while time+128 >= zmg.ticks() do end
i = i+1
end
then select Tools > Run (threaded). You should put a sleep loop (line 6 and 7) in there or else the browser crashes. So yeah, the Lua code is now ran in a web worker, that is, a different thread from the UI one. All the recent major browsers (including IE10) should support it (or else it would tell you). Have fun, and, as usual, report all the bugs here :)

Glad you managed to fix them. :D How well would the typical Nspire Lua and PRIZM LuaZM game work for now? Would Aspirin run?

It seems like the IDE doesn't work at all in Opera. If I click Run or Run Threaded, nothing happens and the browser just starts being laggy.

Nspire Lua: not supported yet. Nor are keys in threaded mode. Yet. Aspirin: I dunno I think there's a syntax error somewhere. Also tested Bloxorz: works fine. But as I said, I still have to work on keys. Maybe test moar stuff too. Such as Opera. And other games. Did you tried the default program?

Yep and nothing at all happened either other than browser lag almost freezing Opera.

It works for me in Opera 12.14, I can't move the windows though.

Also added a sample browser and some small fixes. (Hope you don't mind I've put your ball program in there Spenceboy98.)
