http://d.puremagic.com/issues/show_bug.cgi?id=2398 Summary: writef("%x") for a pointer is always uppercase Product: D Version: 1.035 Platform: PC OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: bugzilla digitalmars.com ReportedBy: clugdbug yahoo.com.au prints ABCD, expect abcd. It's treating %x as if it were %X. Applies to function pointers as well as data pointers. Applies to writefln as well as writef. Applies to DMD2.019 also. This behaviour occurs because of line 794 of format.d, which sets uppercase to 1: case Mangle.Tpointer: vnumber = cast(ulong)va_arg!(void*)(argptr); ----> uc = 1; flags |= FL0pad; I can't see any reason for it, and I can't see this behaviour documented anywhere (the docs for %x say that it must be an integral type, which isn't true in this case). FIX: remove line 794. Possibly adjust the docs for %x/%X, to state that "%x/%X may be used for pointer types". --- import std.stdio; void main() { uint *q = cast(uint *)0xabcd; writef("%x", q); } --

BUT, %x should override that default. It's a simple bug. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
