Hi,

would it be possible to add a function that is called whenever an error occurs?

For example there would be a function prototype errorFct() that could be overridden by an implementation and is called whenever an error occurs so that we could add some additional debugging code. It would be great if that function could be called before the error popup is displayed.

I don't know a situation where an error handler would make much sense. Errors are caused either by bugs in the script, or by wrong external files. Bugs in the script must be fixed; an error handling function won't help better than the error message. Script crashes are caught with the C++ "try/catch" mechanism, which won't give you more info about the crash as you already have in the error message.

Wrong or missing external files normally won't cause an error message unless they are essential for continuing the program. Otherwise, the function using them just returns an error value, usually 0, that you can evaluate in the script. A general error handler for this type of errors will tell you less than when you evaluate the return values.

a try/catch is always useful when working with data coming from external, like e.g. parsing a file.

I really missed a try/catch mechanism when I wrote my XML parser in Lite-C...

I agree: "Bugs in the script must be fixed" ... but that's the point. I think such an error handler could help to analyze the error and with that to fix it.
For example sometimes it would be very useful to get a list of all currently running functions when an error occurs. This could be done in such an error handler function.

b.t.w. a try/catch mechanism in lite-c would be great, too.

Please implement such an on_error method!
This would allow to work out a stackwalk to catch eventual DLL-Errors with the correct(!!) function name.
