http://d.puremagic.com/issues/show_bug.cgi?id=3883 Summary: Line number and file name of Exception instantiation Product: D Version: 2.040 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: druntime AssignedTo: sean invisibleduck.org ReportedBy: bearophile_hugs eml.cc I suggest to add to Exception (so later it can be shown if uncaught) the line number and file name where it was instantiated: void foo() { auto e = new Exception(""); // instantiation line number here throw e; } void main() { foo(); } Exceptions get caught, rethrown, stored, etc. But in many cases they are instantiated close to where their cause is. So knowing such line number can be useful (if you are using a debugger this is not so useful). The compiler fills such fields automatically, so the syntax usage of Exception is unchanged. Such fields can be immutable, and eventually they can be read by user code too. The name and file name added increases the size of the Exception instances (and the binary size too a little), but I think this can't cause problems in normal programs. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
