Hi is it possible to add an event like 'on_error' that allows us to execute a function when an error occurs. I could really use this for my scripting app.

Preferably parameters such as 'line_number' and 'current_module' would be passed to the function. By 'current_module' I mean the object/function that the error occured in.

If there was a way to hook this up when compiling a script too that would be awesome. Right now 'ackerr.txt' only prints the first error it finds.

The compiler can not continue after an error. That's why you only get the first error on compiling.

hmm, well what about at runtime, eg when trying to use a NULL pointer. You get an error box shown up, so is there a way to hook an event to that?

Yes, through the debugging interface when calling the engine through C++. You can pass a callback function pointer to engine_open. You'll find details in the comment in afuncs.h. There is no such mechanism in lite-C.

would it be possible to add a mechanism for lite-c?

It certainly would, but is sort of complicated. I will think about a solution. But don't hold your breath, this is getting a low priority due to a low cost-benefit ratio.

Why is it a low cost-benefit ratio?

I am regularly annoyed that lite-c has no capability of "trapping" errors.

The amount of duplicated code needed to "dodge" errors could be greatly
reduced with a simple "on_error" event in the engine.

Being able to trap and handle errors with our own code should IMHO be manditory.

I'd prefer try...catch

Yeh, try/catch/finally would be great, but for my purposes I wanted to be able to refer the user, back to my scripting application and highlight the line that crashed, replicating VS's functionality. So 'on_error' would be great.
