I figure more than a few members would be too noisy. Which ones to omit then? I'm open to ideas, but it needs to be done as a follow-up, to give us a chance to fix the QMP documentation regression in time for 2.9. >> + The members of 'QCryptoBlockOptionsLUKS' when 'format' is "luks" >> >> Since: 2.6 >> >> A simple union's branch adds a member 'data' of some other type. >> Generate documentation for that member. >> >> Example change (qemu-qmp-ref.txt): >> >> -- Simple Union: SocketAddress >> >> Captures the address of a socket, which could also be a named file >> descriptor >> >> Members: >> 'type' >> Not documented >> + 'data: InetSocketAddress' when 'type' is "inet" >> + 'data: UnixSocketAddress' when 'type' is "unix" >> + 'data: VsockSocketAddress' when 'type' is "vsock" >> + 'data: String' when 'type' is "fd" > > Looks reasonable. > >> >> Since: 1.3 >> >> Signed-off-by: Markus Armbruster <armbru@redhat.com> >> --- >> scripts/qapi2texi.py | 27 ++++++++++++++++++++------- >> 1 file changed, 20 insertions(+), 7 deletions(-) >> > > Reviewed-by: Eric Blake <eblake@redhat.com> Thanks!

A flat union's branch brings in the members of another type. Generate a suitable reference to that type. Example change (qemu-qmp-ref.txt): -- Flat Union: QCryptoBlockOpenOptions The options that are available for all encryption formats when opening an existing volume Members: The members of 'QCryptoBlockOptionsBase' + The members of 'QCryptoBlockOptionsQCow' when 'format' is "qcow" + The members of 'QCryptoBlockOptionsLUKS' when 'format' is "luks" Since: 2.6 A simple union's branch adds a member 'data' of some other type. Generate documentation for that member.
