This is a re-send of this patchset from Apr-24, after multiple pings. I rebased it on top of current qemu/master, though nothing has really changed - it is still the same changes. We should either apply it or drop it if it is not appropriate for some reason. Complete silence for half a year isn't really nice, I think :) ---- Quite big patchset trying to implement normal, readable qemu-img --help (and qemu-img COMMAND --help) output with readable descriptions, and adding many long options in the process. In the end I stopped using qemu-img-opts.hx in qemu-img.c, perhaps this can be avoided, with only list of commands and their desrciptions kept there, but I don't see big advantage here. The same list should be included in docs/tools/qemu-img.rst, - this is not done now. Also each command syntax isn't reflected in the doc for now, because I want to give good names for options first, - and there, we've quite some inconsistences and questions. For example, measure --output=OFMT -O OFMT, - this is priceless :) I've no idea why we have this ugly --output=json thing, why not have --json? ;) I gave the desired format long name --target-format to avoid clash with --output. For rebase, src vs tgt probably should be renamed in local variables too, and I'm not even sure I've got the caches right. For caches, the thing is inconsistent across commands. For compare, I used --a-format/--b-format (for -f/-F), - this can be made --souce-format and --target-format, to compare source (file1) with target (file2). For bitmap, things are scary, I'm not sure what -b SRC_FILENAME really means, - for now I gave it --source option, but this does not make it more clear, suggestions welcome. There are many other inconsistencies, I can't fix them all in one go. Changes since v2: - added Dan's R-Bs - refined couple cvtnum conversions - dropped "stop printing error twice in a few places" Michael Tokarev (27): qemu-img: measure: convert img_size to signed, simplify handling qemu-img: create: convert img_size to signed, simplify handling qemu-img: global option processing and error printing qemu-img: pass current cmd info into command handlers qemu-img: create: refresh options/--help qemu-img: factor out parse_output_format() and use it in the code qemu-img: check: refresh options/--help qemu-img: simplify --repair error message qemu-img: commit: refresh options/--help qemu-img: compare: refresh options/--help qemu-img: convert: refresh options/--help qemu-img: info: refresh options/--help qemu-img: map: refresh options/--help qemu-img: snapshot: allow specifying -f fmt qemu-img: snapshot: make -l (list) the default, simplify option handling qemu-img: snapshot: refresh options/--help qemu-img: rebase: refresh options/--help qemu-img: resize: do not always eat last argument qemu-img: resize: refresh options/--help qemu-img: amend: refresh options/--help qemu-img: bench: refresh options/--help qemu-img: bitmap: refresh options/--help qemu-img: dd: refresh options/--help qemu-img: measure: refresh options/--help qemu-img: implement short --help, remove global help() function qemu-img: inline list of supported commands, remove qemu-img-cmds.h include qemu-img: extend cvtnum() and use it in more places docs/tools/qemu-img.rst | 4 +- qemu-img-cmds.hx | 4 +- qemu-img.c | 1311 ++++++++++++++++++++++-------------- tests/qemu-iotests/049.out | 9 +- 4 files changed, 821 insertions(+), 507 deletions(-)
