IPv6 address entry was not updated to use display_table_row which led to
a shifted line in table, as shown below:
$ iwctl station wlan0 show | head | sed 's| |.|g'
.................................Station:.wlan0................................
--------------------------------------------------------------------------------
..Settable..Property..............Value..........................................
--------------------------------------------------------------------------------
............Scanning..............no...............................................
............State.................connected........................................
............Connected.network.....Clannad.Legacy...................................
............IPv4.address..........192.168.1.12.....................................
............IPv6.address........fdc3:541d:864f:0:96db:c9ff:fe36:b15............
............ConnectedBss..........cc:d8:43:77:91:0e................................
This patch aligns IPv6 address line with other lines in the table.
Fixes: 35dd2c0821 (client: update station to use display_table_row, 2022-07-07)
This change removes duplicate calls to display_table_footer(), in
station show.
Before this change, the bug caused an extra newline to be output every
time the table updated. This only occurred when the network was
disconnected.
$ iwctl
[iwd]# station wlan0 show
The limitations of readline required that the autocompletion choose
a 'default' device. With multiple phys this doesn't work. Now the
readline limitation has been worked around and station can look up
the device for the command completion.
There is a limitation of libreadline where no context/userdata
can be passed to completion functions. Thi affects iwctl since
the entity value isn't known to completion functions.
Workarounds such as getting the default device are employed but
its not a great solution.
Instead hack around this limitation by parsing the prompt to
extract the entity (second arg). Then use a generic match function
given to readline which can call the actual match function and
include the entity.
The existing color code escape sequences required the user to set the
color, write the string, then unset with COLOR_OFF. Instead the macros
can be made to take the string itself and automatically terminate the
color with COLOR_OFF. This makes for much more concise strings.
When station 'show' is invoked, parse and print any IP addresses
associated with the interface.
If iwd network configuration is disabled and no IP addresses were
configured, print a hint to the user that a DHCP client might need to be
configured.
WEP networks are not supported by iwd. However, the only indication is the
message "Operation not supported" while trying to connect. It is not clear
enough that this is due to intentional lack of support (as opposed to some
kind of misconfiguration). This patch explicitly lists WEP networks shown
with get-networks as unsupported. Hopefully this will make it clearer for
those of us not as familiar with iwd.
The diagnostic interface will now only come up when station is
connected. This avoids the need for display station to return
a 'connected' out parameter. We can instead just see that
the diagnostic interface doesn't exist.
The information requested with GetDiagnostics will now appear in
the "station <iface> show" command. If IWD is not connected, or
there is no diagnostic interface (older IWD version) 'show' will
behave as it always has, only showing scanning/connected.
Station, WSC, Ad-Hoc and AP family_arg_completion functions were
identical except for which commands they were referencing and the
interface type they were interested in. Combine all these into a single
function.
