Implement clipboard menu as GNOME Shell Extension

[Chelmite]

In classic GNOME application indicators are not shown per default so no Diodon icon appears.

For application indicator to be shown following extension needs to be installed:

https://extensions.gnome.org/extension/615/appindicator-support/

It would be better though that Diodon supports GNOME Shell extensions directly. Patches are welcome (they could simple access Diodon through libdiodon library).

A test version can be found at https://github.com/RedHatter/diodon-gnome-indicator

Have you already tried running newest version 1.7.0 which I have just released?

It's available in the stable ppa https://launchpad.net/~diodon-team/+archive/ubuntu/stable

Potentially after installation a reboot resp. logout/login is needed for GNOME to recognize new indicator in top bar.

Let me know whether this works for you.

[Chelmite (steve-kelem)]

I tried it, but it makes no difference.

[Oliver Sauder (sao)]

I am not able to reproduce this on my 17.10 machine. The icon appears as normal running version 1.7.0.

Could you attach diodon_debug.txt and env.txt files running following commands:

killall diodon
env | grep XDG > env.txt
G_MESSAGES_DEBUG=all diodon > diodon_debug.txt

once Diodon is running in one terminal what happens when you start Diodon in a second terminal again. Does the menu pop up?

[Chelmite (steve-kelem)]

With Diodon running in one terminal, when I start another one in a 2nd
terminal, the diodon clipboard list pops up.
The menu bar shows 5 entries for Firefox, 2 entries for terminals, keyboard
language, clock & date, wifi, volume, and battery level.
There is nothing on the menu bar for Diodon.

I attached the env.txt file. diodon_debug.txt is empty. Diodon is still
running, so I kill -1'ed it...still empty.

It seems that you use classic Gnome and not the Ubuntu Gnome.

Gnome dropped support for application indicator whereas Ubuntu GNOME still supports it.

So if you wanna see the application indicator in GNOME you need to install an extension:

https://extensions.gnome.org/extension/615/appindicator-support/

Hope this works.

[Chelmite (steve-kelem)]

Yeah! It works again!

Thanks!
Steve

[Chelmite (steve-kelem)]

Is there a way to detect this and warn the user?

[Oliver Sauder (sao)]

I do not think so. Even if there wouldn't be a good spot to put such a warning, as there is basically no indication that Diodon is running.

A solution is to actually implement a GNOME Shell Extension.

I changed the bug accordingly - as I am not an expert on this front patches are always welcome.

[Chelmite (steve-kelem)]

Seems fixed to me. Maybe add a line to the -h help or the man page (or both).

 Thanks for you help!

I made a GNOME Shell extension for Diodon a little while ago. Required a plugin to Diodon exposing the api as a DBus service.

https://github.com/RedHatter/diodon-plugins

[Oliver Sauder (sao)]

Great!

One question though do you think it is possible to access libdiodon.so library directly from the Gnome Indicator instead of a D-Bus?

I have actually implemented the Unity Diodon Scope [0] this way. What I had to do is to simply instantiate `ZeitgeistClipboardStorage` to work with the storage. Pasting can be done by executing the clipboard uri.

[Timothy (redhatter271-deactivatedaccount)]

I originally had trouble accessing libdidon from Gjs but I've got that worked out now. Still one issue though. How do I access the Controller instance from libdiodon without being a plugin?

I could still create a new ZeitgeistClipboardStorage (like you did with the scope) but that has its own set of issues.

[Timothy (redhatter271-deactivatedaccount)]

Never mind. Using ZeitgeistClipboardStorage should work. The issues where due to the poor reading of the source.

[Oliver Sauder (sao)]

As an explanation directly using ZeitgeistClipboardStorage works as it then connect to the D-Bus Service of Zeitgeist.

The only thing which I think will be missing for you is to show the preferences dialogue. This we could add as a command line property though directly into Diodon.

[Timothy (redhatter271-deactivatedaccount)]

Unfortunately, Gjs is having trouble interfacing with libdiodon.so. When initializing a new class constructors are never called.

I've created a bug report here https://gitlab.gnome.org/GNOME/gjs/issues/111

[Timothy (redhatter271-deactivatedaccount)]

I was able to find a workaround for that first issue (though look at the comments, maybe we should consider moving to construct blocks in libdiodon?) but have run into another issue that is causing much more difficulty.

Gjs doesn't have any mechanism for dealing with return types of void* which means all Vala generics. I'm still trying to come up with a workaround but basically, at this time, there is no way to access items from a Gee collections in Gjs.

Bug report here https://gitlab.gnome.org/GNOME/gjs/issues/112

[Timothy (redhatter271-deactivatedaccount)]

New diodon-gnome-indicator version using libdidodon directly. Note: requires the latest code from diodon master.

[Vadim Peretokin (vperetokin)]

What is the latest status of getting a Diodon icon up in Gnome Shell on Ubuntu 18.04?

[Oliver Sauder (sao)]

As mentioned above you can check it out at https://github.com/RedHatter/diodon-gnome-indicator and give us feedback how it works for you.
