Command line options to manipulate qjackctl

[tkna91]

I have to use the mouse to do the work of right-clicking the qjackctl tray icon and clicking Reset. Is it possible to do those things with qjackctl command line options?

If not, it would be useful if the following menu operations could also be specified with command line options.

• Stop
• Reset
• Session
• Messages
• Status
• Graph
• Connections
• Patchbay
• Setup
• Quit

Please consider adding the feature.

Environment:

• qjackctl 1.0.2-1
• qt6-base 6.7.3-2
• OS: Arch Linux x86_64
• Kernel: 6.11.1-arch1-1
• WM: sway

most of those commands are available from the native d-bus interface (cf. Setup > Misc > Other > Enable D-Bus Interface).

eg. usage: dbus-send --system / org.rncbc.qjackctl.{start|stop|reset|quit|...}

ps. as matter of fact the reset d-bus method was missing, now added in c7b7068 (develop branch).

I see. It seems that the commands can be extracted as follows

https://github.com/rncbc/qjackctl/blob/main/src/qjackctlMainForm.cpp#L847

dbus-send --system / org.rncbc.qjackctl.start
dbus-send --system / org.rncbc.qjackctl.stop
dbus-send --system / org.rncbc.qjackctl.reset
dbus-send --system / org.rncbc.qjackctl.main
dbus-send --system / org.rncbc.qjackctl.messages
dbus-send --system / org.rncbc.qjackctl.status
dbus-send --system / org.rncbc.qjackctl.session
dbus-send --system / org.rncbc.qjackctl.connections
dbus-send --system / org.rncbc.qjackctl.patchbay
dbus-send --system / org.rncbc.qjackctl.graph
dbus-send --system / org.rncbc.qjackctl.rewind
dbus-send --system / org.rncbc.qjackctl.backward
dbus-send --system / org.rncbc.qjackctl.play
dbus-send --system / org.rncbc.qjackctl.pause
dbus-send --system / org.rncbc.qjackctl.forward
dbus-send --system / org.rncbc.qjackctl.setup
dbus-send --system / org.rncbc.qjackctl.about
dbus-send --system / org.rncbc.qjackctl.quit
dbus-send --system / org.rncbc.qjackctl.preset
dbus-send --system / org.rncbc.qjackctl.active-patchbay
dbus-send --system / org.rncbc.qjackctl.load
dbus-send --system / org.rncbc.qjackctl.save
dbus-send --system / org.rncbc.qjackctl.savequit
dbus-send --system / org.rncbc.qjackctl.savetemplate

After a quick check, I could not seem to perform the following...am I doing something wrong?

$ dbus-send --system / org.rncbc.qjackctl.active-patchbay
Invalid signal name: Member name was not valid: 'active-patchbay'
$

[rncbc]

active-patchbay and preset commands need an argument of type string

eg. dbus-send --system / org.rncbc.qjackctl.active-patchbay string:/path/to/patchbay.xml

Okay, thanks. I feel like it would be nice to have an explanation in the manual, since it is not very obvious what to do with the above list of objects in general that can be manipulated with d-bus, and the following in particular. How do you feel about it?

dbus-send --system / org.rncbc.qjackctl.preset string:FILEPATH
dbus-send --system / org.rncbc.qjackctl.active-patchbay string:FILEPATH
dbus-send --system / org.rncbc.qjackctl.load
dbus-send --system / org.rncbc.qjackctl.save
dbus-send --system / org.rncbc.qjackctl.savequit
dbus-send --system / org.rncbc.qjackctl.savetemplate

IIRC the preset parameter is the preset name, not a file path:

dbus-send --system / org.rncbc.qjackctl.preset string:LABEL

although as usual documentation is buried deep in the ChangedLog, feel free to propose yourself a PR to extend the qjackctl.1 man page. thanks
