Changes underneath the surface – Diodon 1.2.0

I am glad to announce that another Diodon version has been released today with mainly changes underneath the surface such as improving API for plugin developers but also fixing some annoying bugs.

Here in detail what has changed:

  • Fixed issue which could cause Diodon not starting when upgrading to a newer version (#1347181)
  • Fixed issue that under certain desktop environments Diodon was not always added as startup application (#1348989)
  • Improved plugin API (#1323947, #1309893, #1324309)
  • Cleaning up dependencies for easier integration into other distributions (#1348994, #1310360)
  • Updated translations

You can either download the new Diodon as a tarball or if you use Ubuntu or an Ubuntu based distribution use the stable ppa by running following commands:

sudo apt-add-repository ppa:diodon-team/stable
sudo apt-get update
sudo apt-get install diodon
# and for all Unity users there is also a scope
sudo apt-get install unity-scope-diodon

Thanks to everyone involved who made this release happen providing translations, reporting bugs, working on packaging, contributing source code or just simply using and advocating Diodon. Hope to see many more releases ahead.

Where is my Diodon monochrome icon?

You might have been using Diodon for a while and are wondering why there is no monochrome icon in your panel but instead a colored fish?

This could look like the following:


The icon does look a bit out of place in this specific theme. Unfortunately it is impossible to create an icon which suits every theme very well and if we would use a monochrome icon as the default it might not even show up on certain themes. That’s why we have decided to have a colored fish as the default panel icon as it is at least visible on all themes. For some commonly used themes we made some exceptions to use the monochrome icons directly.

However, in case you use a completely different theme and you would still like to have a Diodon monochrome icon there is a fairly quick way to do it.

You can use following command if you have a dark theme:
sudo ln -sf /usr/share/icons/ubuntu-mono-dark/status/22/diodon-panel.svg /usr/share/icons/[MYTHEME]/status/22/diodon-panel.svg

or this command with a light theme:
sudo ln -sf /usr/share/icons/ubuntu-mono-light/status/22/diodon-panel.svg /usr/share/icons/[MYTHEME]/status/22/diodon-panel.svg

In both cases replace [MYTHEME] with whatever theme you are using.

And last you need to update the cache of your theme with the following:
sudo gtk-update-icon-cache /usr/share/icons/[MYTHEME]/

Done. When you now close Diodon and open it up again a monochrome should be shown in your panel.

What I would recommend you though if you want to have a more permanent solution: Get in touch with your theme author and ask whether he would be willing to ship a monochrome icon for Diodon. In the end does the author know best what suits its theme and when the Diodon icons are shipped with the theme itself all users will benefit.

New but old and what changes for our CleverCleaner users

I have finally made it to migrate from my old webhosting provider to a new one. Nothing really to bother you about it but I am actually quite excited about my new webhosting and the many possibilities it gives me – so if you are looking for a new webhoster yourself you might want to have a look here .

While I was in the migration process have I changed a couple of thing which might be noteworthy. For all readers of “The Esite Code Log”-Blog, nothing has really changed for you though, beside a new look and feel. The blog and its philosophy remains the same as before. You can read more about it here.

More has changed for our CleverCleaner users though. Up to this point I maintained a single blog only for the CleverCleaner project. For simplicity and maintenance reasons have I decided though to consolidate the CleverCleaner blog with The Esite Code Log. So CleverCleaner is now treated as any other open source project I am involved in such as Diodon. This means there will be no more German translation of my blog posts for CleverCleaner (of course the German translation of the CleverCleaner tool itself remains as before) and all blog posts respectively news concerning CleverCleaner are tagged with clevercleaner on this blog.

So if as before you just want to subscribe to CleverCleaner news per RSS you can use this feed (just as a side node you can also use the same link and replace tag name clevercleaner with whatever tag you want to subscribe to, quite handy…). Beside news for CleverCleaner have I moved all more in depth descriptions and support information to the SourceForge project side mainly its wiki.

As it has been pretty quiet on this blog for a while do I hope that this change will decrease the time I need for maintenance and actually gives me more time to program on the different open source projects and in the end be able to post about it here… 😉

So therefore stay tuned.

Another Diodon milestone released

I am happy to announce another Diodon milestone 1.1.0 being released today.

You can download it as tarball here or if you use Ubuntu simply install it with the stable ppa:

sudo add-apt-repository ppa:diodon-team/stable
sudo apt-get update
sudo apt-get install diodon unity-scope-diodon

Due to changed dependencies will this version only be available for Saucy 13.10 and Trusty 14.04. Of course for older flavors there will still be an older version available in the ppa and also as tarballs.

This new version finally removes the limitation of maximum 100 items in the clipboard history and therefore brings with it a much more powerful Unity Scope integration and lots more.

If you want to know more in detail what has changed read the following posts:

This milestone is only a start creating the foundation for future improvements such as better integration into other desktop environments and more. I keep you posted.

With this in mind… Happy copying.

Introducing new default settings for Diodon

Diodon version 1.1.0 is shaping up very nicely and is hopefully soon going to be released after some last polishing.

Before this is gonna happen I want to introduce you to two new default settings which further make Diodon a slick and fast utility with as less footprint as possibly but still keeping options available for more advanced users. But let me elaborate.

Disabling of primary selection support by default

Primary selection support has been added to Diodon since its very first version. What this features does is when a certain text is selected in any editor it will automatically be added to the clipboard history and then it is accessible from the Diodon indicator or unity scope to paste at any time. This is cool especially when you frequently just select and paste with a middle mouse click in a different editor. As a primary selection can also be pasted with the shortcut <Shift>Insert when such support is enabled, Diodon is able to instant paste in applications which do not support <Ctrl>V for paste (e.g. Gnome Terminal).

However this feature also brings some disadvantages with it. First of all it floods the clipboard history with quite some items and especially if you do not use the select/paste feature at all. This distracts you from finding the items you actually want to paste. Furthermore does enabling of this feature potentially drains your battery quicker in case you are not connected directly to a power source.

Advantages and disadvantages indicate that primary selection support is an advanced feature. We therefore have decided to disable it by default but of course you are still able to enable it again in the Diodon preferences.

Not adding images to clipboard history by default

In versions before 1.1.0 Diodon added images to the clipboard history at all times. Those images can for instance be copied by your browser to the clipboard when you right click on an image and choose “Copy image”. Or also when you create a print screen and choose “Copy to clipboard”.

Nice but why do you want to disable this you might ask? Well unfortunately images are in general much bigger than just some text. This has an impact on the memory consumption of Diodon. So Diodon needs to copy the image to the memory and then create previews for it so you can easily identify it when you paste it. There are also some circumstances where image applications like Gimp constantly copy images to the clipboard which gives Diodon a lot of work to do increasing therefore CPU usage – and actually in most cases the many pictures copied by Gimp you do not really want to add to your clipboard history.

As this feature is not so often used and there is a possibility to decrease the memory footprint of Diodon, it is now disabled by default so images won’t be added to the clipboard history automatically. There is though an option available in Diodon preferences where you can enable it again.


No worries though. Disabling “Add images to clipboard history” won’t delete any image items from the history which have been copied previously. Such will always be available to be pasted for you till you decide to clear them from your history. That also means that you can temporarily enable/disable the feature whenever you need to without loosing any items copied already.

Want to test run it?

Convinced and want to test run it? You can do this with the following commands:

sudo add-apt-repository ppa:diodon-team/daily
sudo apt-get update
sudo apt-get install diodon unity-scope-diodon

Remember though that this is still a test version which might have issues. If you find any please report them. And also let us know what you think about this change in the comments section below.
