http://d.puremagic.com/issues/show_bug.cgi?id=9780 Summary: Maybe bad formatted write of array of 2-tuples Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: nobody puremagic.com ReportedBy: bearophile_hugs eml.cc This is wrong code because %(...%) is currently not supposed to be able to unpack a tuple: import std.stdio: writefln; import std.typecons: tuple; void main() { auto data = [tuple(1, 2), tuple(3, 4), tuple(5, 6)]; writefln("%(%s %s\n%)", data); } DMD 2.063alpha prints: Tuple!(int, int)(1, 2) %s Tuple!(int, int)(3, 4) %s Tuple!(int, int)(5, 6) I am not sure, but I think the printing of "%s" is a bug. I think that program should raise a formatting error like in this case: import std.stdio: writefln; import std.typecons: tuple; void main() { writefln("%s %s", tuple(1, 2)); } std.format.FormatException C:\dmd2\src\phobos\std\format.d(431): Orphan format specifier: %%s %s (Generally I hate D/DMD to not give compile-time errors for this. But this is a different topic.) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
