This series allows to only display a given list of help sections.
v5: introduce "-help[=LIST]", move help of help to the end "all" section.
Remove typo fix (already included).
v4: as proposed by Eric, provide a list of sections, restore default -help
v3: add a 2nd patch to add an help section, -help displays only this section
v2: simplify the dance of #define/#undef, thanks to Marc-André.
Laurent Vivier (2):
vl: Allow to define optional parameter with -arg[=params]
Use help sub-sections to create sub-help options

I agree - a bit more order is IMHO needed in the general -help - I'm not sure this is the place to start. E.g. it is not your fault that it lists e.g. a ton of random stuff as Standard options but this becomes more of a problem if you hide things behind sub-sections. For example, how do I change the amount of memory? Currently I do --help and search for memory. This also diverges from the way one queries other help (-device foo,help, -cpu help etc). How about we move detailed help into each option instead? This will mean only 113 lines which is a lot, but kind of reasonable. -machine [type=]name[,prop[=value][,...]] select emulated machine ('-machine help' for help) -cpu cpu select CPU ('-cpu help' for list) -smp [cpus=]n[,prop[=value][,...]] configure SMP ('-smp help' for help) -numa node[,prop[=value][,...]] configure NUMA ('-numa help' for help) Of course it's also true that often the help says nothing useful at all. > As sections already exist in the help description, > add some options to only display the wanted section. > > '-help' now can take an optional parameter of the > form -help[=LIST], which is a comma separated list > of sections to display: > > all display all help sections > help display help options > standard display standard options What does standard options mean? > block display block options > usb display usb options > display display display options > machine display machine options > network display network options > character display character options Character device options? > url display url options what are these? > bt display bt options bluetooth options? > tpm display tpm options > kernel display kernel options > expert display expert options > object display object options what are these? > > '-help' without option displays only help options. > > Example: > > $ x86_64-softmmu/qemu-system-x86_64 -help=kernel,usb > QEMU emulator version 2.4.50, Copyright (c) 2003-2008 Fabrice Bellard > usage: qemu-system-x86_64 [options] [disk_image] > > 'disk_image' is a raw hard disk image for IDE hard disk 0 > > Linux/Multiboot boot specific: > -kernel bzImage use 'bzImage' as kernel image > -append cmdline use 'cmdline' as kernel command line > -initrd file use 'file' as initial ram disk > -dtb file use 'file' as device tree image > > USB options: > -usb enable the USB driver (will be the default soon) > -usbdevice name add the host or guest USB device 'name' > > Signed-off-by: Laurent Vivier <lvivier@redhat.com> Maybe a good place to start is rewriting our man page.

I guess it's fine, so Libvirt hasn't used -help for quite a while now - we exclusively use QMP to probe, and refuse to use -help if we find we have a new enough QEMU for QMP to work Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| ^ permalink raw reply [flat|nested] 13+ messages in thread
