Obfuscator

Has somebody experiences about obfuscated javascript code?

I see, that all "main.js" of my html5 apps are clearly readable. It would be very helpful if at least the variable names, function names and strings would be reduced to a short string or obfuscated.

I tried an online obfuscator, but the result was double size and not working....

***EDIT***

Ok,... I fould Google Closure. It seems to work pretty good. The code was reduced to a third, all names are a or b or c or a combination of it. The strings are kept as they have been.

Now it would be very helpful, if MONKEY eliminates the PRINT command lines in RELEASE version. I use this only for debug purposes. Mark, could you add a feature to switch ON/OFF elimination in TED?

Google have something called Closure that can be used

I do use PRINT for debugging too, but I guess someone could use it for their actual game.

What about wrapping Print yourself?

Strict

Function Main:Int()
	Print "Start"
	Return 0
End

Function Print:Void(str:String)
	#If CONFIG="debug"
		monkey.Print str
	#End
End

This is the way I do it alread to switch on/off debug printing to a console.

But it is no solution if I want to obfuscate all string texts. Comment out all print commands is a possibility, because monkey compiler eliminates such comments.

I do not ask for a elimination of PRINT commands, but I want to have a flag in TED's setting window, where the user can decide how to handle he PRINT commands.

Why would you want to do that? Say if you use DrawText in your game, you wouldn't want the string to obfuscated!

but I want to have a flag in TED's setting window

TED is just a code editor, Monkey is the place you want to control it and you can with the CONFIG pre-processor.

I want to eliminate the PRINT commands, because they say a lot about my code. And if they still are inside an obfuscated script, they still give a hint, what the original variable name was:

LicenceCode=LoadText("...
Print "Licence code= " + LicenceCode

So I can create a pre precessor function and and a corresponding flag which could eliminate all lines wih PRINT at the left? Is it such flexible?

You can comment all "print(" in the main.js. Example (*nix):

sed 's#\(print("\)#// \1#g' main.js > main_noprint.js

Closure will remove commented lines.
