Debug information for enumerator values
I've implemented this in gdc. https://github.com/D-Programming-GDC/GDC/commit/021dda8feaba282fec60600729ba8abc2c64cf81 --- enum enum_byte : byte { kE1, kE2, kE3 } enum enum_ubyte : ubyte { kE1, kE2, kE3 } enum enum_short : short { kE1, kE2, kE3 } enum enum_ushort : ushort { kE1, kE2, kE3 } enum enum_int: int{ kE1, kE2, kE3 } enum enum_uint : uint { kE1, kE2, kE3 } enum enum_long : long { kE1, kE2, kE3 } enum enum_ulong : ulong { kE1, kE2, kE3 } void main() { enum_byte var_byte; enum_ubyte var_ubyte; enum_short var_short; enum_ushort var_ushort; enum_int var_int; enum_uint var_uint; enum_long var_long; enum_ulong var_ulong; } --- (gdb) print var_byte $1 = test.enum_byte.kE1 (gdb) print var_ubyte $2 = test.enum_ubyte.kE1 (gdb) print var_short $3 = test.enum_short.kE1 (gdb) print var_ushort $4 = test.enum_ushort.kE1 (gdb) print var_int $5 = test.enum_int.kE1 (gdb) print var_uint $6 = test.enum_uint.kE1 (gdb) print var_long $7 = test.enum_long.kE1 (gdb) print var_ulong $8 = test.enum_ulong.kE1 (gdb) print (ulong)var_ulong $9 = 0 (gdb) print (byte)'test.enum_uint.kE2' $10 = 1 '\001' (gdb) print ('test.enum_ulong')3 $11 = (test.enum_ulong.kE2 | test.enum_ulong.kE3) (gdb) print ('test.enum_ulong')2 $12 = test.enum_ulong.kE3 (gdb) print ('test.enum_ulong')4 $13 = (unknown: 4) What do you think? Is .. too verbose, or just right? :-) Regards Iain

As I plan to get round to hacking it sometime soon... -- Iain Buclaw *(p < e ? p++ : p) = (c & 0x0f) + '0';

(gdb) p &'test.foo' Can't take address of "test.foo" which isn't an lvalue. (gdb) p &baz Can't take address of "baz" which isn't an lvalue. Hope this helps those who use CTFE a lot. ;-) -- Iain Buclaw *(p < e ? p++ : p) = (c & 0x0f) + '0';
