dump ¶By default, the hexadecimal display shows two bytes grouped together,
and then a space. You can alter this behaviour using the group_by
parameter.
(poke) dump :ascii 0 :size 0x40#B :group_by 4#B 00000000: 68f19a63 df2a8886 c466631c a7fdd5c7 h..c.*...fc..... 00000010: 3075746a 0adb03ca f5b1ff14 6166fa07 0utj........af.. 00000020: 0dd3cfbd 8eff46a2 4152a81d 471beddf ......F.AR..G... 00000030: a0501cae 8bfcec6f 7a4f5701 45ba9fc3 .P.....ozOW.E...
Another parameter is the cluster_by argument.
By setting cluster_by to n, this
causes dump to display an additional space after the nth
group has been displayed, and also in the corresponding position in
the ascii display:
(poke) dump :size 0x40#B :group_by 2#B :cluster_by 4
76543210 0011 2233 4455 6677 8899 aabb ccdd eeff 01234567 89ABCDEF

00000030: 7bbf fa3e 3fc2 43a4 2a1e 9763 2bd6 5d24 {..>?.C. *..c+.]$
Another variable that the user can customize is
pk_dump_nonprintable_char. It defaults to '.', and
contains the character to use in the ASCII dump to represent a
non-printable character.
Not all bytes from an IO space can be read, depending on the kind of
IO device. When dump cannot read a byte it will print
pk_dump_unknown_byte instead, which is a string.
If the variable pk_dump_addr_hyperlinks is 1 then the
dump command will emit hyperlinks in the printed bytes.
Clicking on a byte value will result on the address of that byte to be
inserted at the prompt.
If you have a personal preference on how memory dumps should appear,
you can set the relevant pk_dump_* variables. These
global variables serve as the defaults for dump, so this way, you
will not need to explicitly pass them when you call the function.
