Can you point me to the explanation of this: %(%02X %)%*s %s ?
https://dlang.org/phobos/std_format.html
Under "Example using array and nested array formatting:"
writefln("My items are %(%s %).", [1,2,3]);
So "%( %)" is an array format specifier, with the stuff between
the two as the element format. In the case of "%(%02X %)%*s %s",
that reads:
"%(" // Start array format specifier for arg 1.
"%02X " // Format each element as a 2 digit hex number followed
by a space.
"%)" // End array format specifier.
"%*s" // Right justify arg 3 (""), using width specified by arg
2.
" %s" // And print arg 4 using no special format.
