Rework how the monitor mode works. Instead of having separate paths for the list and monitor mode, reuse the list mode. We simply mark all changes and then list the changes in a loop. This makes it possible to accumulate some updates and print them together. Add a -t option to list the latency params on a port.

# LISTING PORTS AND LINKS
|
|
|
|
Specify one of -o, -i or -l to list the matching optional input and
|
|
output ports and their links.
|
|
|
|
\par -o | \--output
|
|
List output ports
|
|
|
|
\par -i | \--input
|
|
List input ports
|
|
|
|
\par -l | \--links
|
|
List links
|
|
|
|
\par -t | \--latency
|
|
List port latencies
|
|
|
|
\par -m | \--monitor
|
|
Monitor links and ports. **pw-link** will not exit but monitor and print
|
|
new and destroyed ports or links.
|
|
|
|
\par -I | \--id
|
|
List IDs. Also list the unique link and port ids.
|
|
|
|
\par -v | \--verbose
|
|
Verbose port properties. Also list the port-object-path and the
|
|
port-alias.
|
|
|
|
# CONNECTING PORTS
|
|
|
|
Without any list option (-i, -o or -l), the given ports will be linked.
|
|
Valid port specifications are:
|
|
|
|
*port-id*
|
|
|
|
As obtained with the -I option when listing ports.
|
|
|
|
*node-name:port-name*
|
|
|
|
As obtained when listing ports.
|
|
|
|
*port-object-path*
|
|
|
|
As obtained from the first alternative name for the port when listing
|
|
them with the -v option.
|
|
|
|
*port-alias*
|
|
|
|
As obtained from the second alternative name for the ports when listing
|
|
them with the -v option.
|
|
|
|
Extra options when linking can be given:
|
|
|
|
\par -L | \--linger
|
|
Linger. Will create a link that exists after **pw-link** is destroyed.
|
|
This is the default behaviour, unless the -m option is given.
|
|
|
|
\par -P | \--passive
|
|
Passive link. A passive link will keep both nodes it links inactive
|
|
unless another non-passive link is activating the nodes. You can use
|
|
this to link a sink to a filter and have them both suspended when
|
|
nothing else is linked to either of them.
|
|
|
|
\par -p | \--props=PROPS
|
|
Properties as JSON object. Give extra properties when creaing the link.
|
|
|
|
# DISCONNECTING PORTS
|
|
|
|
When the -d option is given, an existing link between port is destroyed.
|
|
|
|
To disconnect port, a single *link-id*, as obtained when listing links
|
|
with the -I option, or two port specifications can be given. See the
|
|
connecting ports section for valid port specifications.
|
|
|
|
\par -d | \--disconnect
|
|
Disconnect ports
|
|
|
|
