For reference, I find these notations most useful (in bees and some other tools I developed):
I didn't find lengths in hex to be very useful compared to the range notation. Range notation in hex shows clearly whether the end of the range is page-aligned regardless of the start of the range. It's also more convenient when overlapping matching ends of ranges.
For device offsets I find units of 1024M with 3 fixed decimal places are useful. 1 GiB-aligned dev_extents are "xxx.001" in that notation. That's really obscure, though, and I don't know of a btrfs-progs tool that even outputs that information other than btrfs ins dump-tree
.
I would be quite happy with what Zygo suggested and don't have very much to add. Range notation would be especially handy! A simple option like --units-hex
would be adequate at least for me, and I'd prefer this over a flexible system that requires more typing.
Do you have suggestion for the option name and format? I think there would need to be list of value categories where this applies, ie. not for inode numbers. I don't know how much flexible the format should be, we can do a preselected list of values where hex format would make sense. If this there's a need to make it more flexible (like adding exceptions for certain types) then the specifier can be enhanced.
Possible format:
--units=hex
