--- Comment #7 from Timothee Cour <timothee.co...@gmail.com> --- For windows: > Please do not forget about Windows - how would you propose handling `dmd -c -od=mydir -op C:\bla.d D:\bla.d` then? ;) => creates: mydir/C/bla.o mydir/D/bla.o but again, as in the proposal user can also write: dmd -c -od=mydir -op=C:\ C:\bla.d D:\bla.d => creates: mydir/bla.o mydir/D/bla.o it's nice and consistent. Another possiblity is to disallow the combo(windows+op+absolute files), but that doesn't seem necessary. But whatever is decided on windows, hopefully we can at least do what's proposed here on mac/linux. --
