A system to throw errors that allow for easy error reporting to the user by showing a translated pop-up alert box with the error message. The messages use strings.xml for translation and allow the usual replacement args (ie [FILE] is replaced with a filename). The exceptions can be cascaded, by adding more (translated) text when caught and then re-throwing the result. Macros are being used to support adding a function name prefix to a message of the current function that the exception is thrown from. The syntax is: <macro>(<line>); to show 'line' <macro>(<alert>, <line>); to append 'line' to a caught alert. <macro>(<line>, <alert>); to prepend 'line' to a caught alert. where <macro> is one of: THROW_ALERT, THROW_MALERT, THROW_FALERT, THROW_FMALERT, THROW_ALERTE, THROW_MALERTE, THROW_FALERTE, THROW_FMALERTE, where M = modal, F = Function name. and where <line> is one of: <xmldesc> <xmldesc>, AIArgs<args> where <xmldesc> is a string literal that will be looked up in strings.xml, and <args> is: (<key>, <replacement>)[<args>] There are more variations of the macros to throw an arbitrary class (append _CLASS), include an int code (append C) or to store the current errno as code (append E). For example, THROW_MALERTC(code, ...), or THROW_FALERT_CLASS(Foobar, ...), where the ... is the same as for the macros above. Documentation and example usage has been added to aialert.h.
