OnScriptError event handler
New, NormalPublic


With OnScriptError event handler tool makers could collect and display the script errors in new and better ways. For example one could create a window that shows all the errors raised

Example of such event handler:

addMissionEventHandler ["OnScriptError",
 params ["_errorMsg","_file","_line"];


The event would be called every time there is a script error


Operating System

Example of what kind of error dialog could be achieved by this feature:

stack trace would also be good with this, with variables also. like in diag_stacktrace

I am not expecting anything but i think it would be neat to have the following feature(s) added to the scripterror event handler:
the handler runs in an overall catch block that redirects the error message from it's default behavior. this is accomplished by not displaying the error message on screen unless one's return value is a string with said error he/she would like to be printed. additionally, one can return value false or true to change the handling of the script as either a continue execution (true) or breakpoint (false) such that he or she can handle the error gracefully (like in the case of code that could cause problems if the code continues with errors). this would give modders the ability to turn off error messages by event this event handler just returning true or saving the errors into a variable for later parsing and analysis or redirecting to the log file or showing the error in the systemchat, etc.
