Custom Error Handler

Post by MicroMacro »

Hey!

I am making a visual version of Love that will work like Scratch in Love. I know, I dunno why I thought it was a good idea either. xD

I need to build an error handler that won't crash the application, but can crash what the user has made so that the user can see what went wrong. So basically something that will catch the error, show where it was (if possible), and then return to the editing program.

Doable?

Thanks. :)

pcall is probably more useful if you want to resume normal operation afterwards: http://www.lua.org/pil/8.4.html

Code: Select all

print( type(love) )
if false then
  baby:hurt(me)
end

I have attached a demo you might find useful (or at least a decent read), since i also experimented with custom error handlers.

I also have a newer, and probably even less buggy (not that the attached one has many...) implementation, but i want to share that via a different way, soon.

Is there any way that after your error handler it could return to the screen I was using? I'm making a visual version of Love in Love (again, I still don't know why) and I want to catch the errors the users mane and then return them to the screen they were programming on.
