I have a number of monitors. I typically move between up to 4 or 5 workspaces for different areas of focus during the day (simply different projects, PyCharm for Python projects vs Eclipse for Java projects, e-mail and project management activities, etc.)
I would like to throw a chat application up on a monitor that would be mapped into all workspaces so that it's always up attracting my attention and doesn't change when I change workspaces.
I don't see in Cinnamon any option to do this and find no search expression getting me help in Google to solve it.
At the moment, this is not possible in Cinnamon. It is a long standing feature request (since 2012!).
However, there are alternatives to it. Namely, the program devilspie2 (available in the repositories) allows one to manage windows and their placement, with the help of a small Lua script.
Here1 is how I stick my Firefox and Pidgin window on all workspaces, while some other windows in a given workspace WORK (because I don't want to see them when I'm not working (: ).
-- Make windows of all these apps visible on all workspaces
GLOBAL_WINDOWS='Firefox;System Monitor;Pidgin'
if (GLOBAL_WINDOWS:find(get_application_name())) then
pin_window();
end
-- Firefox should be tall maximised
if (get_application_name() == 'Firefox') then
maximize_vertically();
end
-- Put the Sublime on their correct workspaces
if (get_application_name() == 'Sublime Text' and get_window_name():find('WORK')) then
set_window_workspace(4);
end
This should be placed in a config file in your home directory. Check the documentation :). And don't forget to set devilspie2 as the first startup app.

Occasionally, my fingers are faster then my brain and accidentally close views or windows of my development environment (which is Eclipse Kepler). I usually have two windows of Eclipse running side by side with individual views configured in both of them. Unfortunately, as soon as I (unintentionally) close a view/window, I have to set it up again. E.g. the build files in my Ant view get lost, I have to reopen files and so on...
Generally speaking, are there any plug-ins or options you can recommend that can help me backup and restore sessions? I'm aware of the "Save perspective" feature, but it barely meets my needs.
To be more precise:
Is there any feature to make Eclipse request my confirmation, before a (top-level Eclipse) window is closed? - I rarely do uncontrolled clicks twice :-)
Is there any plugin to save and restore my current views (incl. build files in Ant view)?
Is there any plugin to save a set of open files I'm currently working on? Would be neat, if I could open several files on a single click and get working right away. I'm thinking of a session management, where I can switch between several sets of open files.
Just in case none of the above is available and I messed up again, are there any files I can copy from one workspace to another to restore my Eclipse setup (windows/views)?
Any hints are welcome.
I am always the first one to jump on any latest Eclipse release thinking that it would solve some of the issue that i have with slowness but i am always disappointed. The DLTK thing that keeps running, memory heap issues, internal error occurred ....
The latest version that I have tried is KEPLER
I know that I can close the projects that i am not using, disable validation, remove projects from the build path, hack into their myriad of codes and change settings but really?
I have to admit my workspace has only 5 projects but more than TWO HUNDRED heavy duty folders. within those folders you have for example, Drupal, Wordpress and so on..
I have used visual studio for years with 5 times as much projects without this kind of slowness but that is besides the point. Let's go back to eclipse.
looking at my settings, some people might say: why don't you create a projects for each of those folders? I tried that but the DLTK indexer keeps on indexing every projects in my workspace unless i close them. WOW!!! Create multiple workspace is out of the questions, if i have to do that i will just ignore Eclipse all together.
My hardware is decent and I have SSD Drive and plenty of RAMs.
What is the largest amount of projects or files can Eclipse safely handle? What about the DLTK what are its limitations?
How large is too large?
What doesn't visual studio seem to suffer from the same slowness? Is the problem java related or with the data structure? Can Eclipse handle that amount of projects?
I know that there are a lot of moving parts and answering these questions is not black and white but why is this thing indexing even the stuffs that i am not using?
I would like to get some opinions on how to use this editor effectively?
While the number of projects/files is not exactly "limited" (beside the resources of the host machine), the number of open editors is.
Eclipse 2019-09 proposes by default 99.
Close editors automatically when reaching 99 open editors
The preference to close editors automatically is now enabled by default.
It will be triggered when you have opened 99 files.
If you continue to open editors, old editors will be closed to protect you from performance problems.
You can modify this setting in the Preferences dialog via the General > Editors > Close editors automatically preference.
IDEs are slow by nature because they do a lot.
I would never use eclipse for webdev stuff like wordpress.
You should be leaving your library files outside of your main project as external folders so that eclipse discounts them. That way you can just have the files you need in your workspace.
Also, try closing the projects you aren't working on by right clicking and choosing "close project"
Personally I use vim and FTP to handle this stuff. Eclipse is nice and integrated but very chunky.
It used to be the case that if I selected two files (or directories) in Package Explorer, I could then right click and use Compare With -> Each Other.
Recently I have found that my workspaces now only allow either a single file or a contiguous range of file to be selected. In other words, Click...Shift+Click does what I expect, but Click...Ctrl+Click doesn't.
Since this works fine for colleagues working with exactly the same version of eclipse (we all module load the same Eclipse deployment) I have to assume that it is a preference of some kind.
Unfortunately, after having gone through the preferences page with a fine tooth comb, I can't see anything which might control this behaviour.
So, can anyone think of a reason why multi-selection may be failing or disables in my explorer, but not that of some of my colleagues?
Note I am working with Eclipse Juno, though I have seen this with previous versions too, on Red Hat Enterprise Linux 6, using the Gnome Desktop Environment.
After many attempts and many failures, I eventually managed to track down this problem.
It seems that if the Gnome preference "Show position of pointer when the Control key is pressed" is enabled† then multi-selection fails in Eclipse.
To fix it, I simply disabled "Show position of pointer when the Control key is pressed"†.
† On my Red Hat Enterprise Linux 6 installation this is located in: System > Preferences > Mouse > General tab, Locate Pointer section
The thing which finally gave my a hint was identifying that this was probably due to the same underlying problem as another I was having with the NoMachine NX client, where the nxclient wasn't passing Ctrl key presses to the remote end at all. See the bug report Enabling Gnome Accessibility option prevents "ctrl" key from being recognized in NX window
After my Eclipse Bugzilla account is created,
I have added a bug report for this problem to the Eclipse Bugzilla: Bug 417573
I write code in several languages (Python, C, C++, and Java) using Eclipse. Is it possible to designate a directory on my machine (say /home/workspace/) as the "primary" workspace for any Eclipse session, but then to have subfolders, /home/workspace/python, /home/workspace/java, etc., in which I can create new Eclipse projects.
I don't want to have to navigate menus and select different workspaces for each session of Eclipse that I start up. I would rather just always have permission to manipulate any projects from a variety of folders at any time, but I can't find a clear answer about whether this can be done and how to do it.
As I understand your question; You want to have one workspace, but be able to code in several different languages without switching workspace but at the same time keep the projects separated?
First I would suggest you consider several workspaces, I find it convenient to keep settings and projects in separate workspaces. I rarely have to switch language that often.
But. I think what you want to do is to keep several working sets. You create one java working set, one C++ set and associate your different projects with a working set. Then you can minimize the java working set when you are running C++. For working sets you dont need any subfolders on the harddrive.
You might also want to look into Mylyn. Its a great tool for those who often are switching context. It saves the context (eclipse perspective, open files, etc) as associated with a task.
How about setting Eclipse to prompt for the workspace at launch? It wouldn't allow you to work in two languages at once, but should do the trick otherwise.
An Eclipse workspace can contain projects slated for different languages and those projects can live anywhere on your hard drive. There are at least two ways to do what you want. When creating a new project, uncheck the Use default location checkbox and browse to or specify the folder where you want your project to live. If a project already exists import the project into the workspace using the File->Import menu option and then select Existing Projects into workspace. In the next screen make sure the checkbox for Copy projects into workspace is not selected. This will leave the source files in the original folder.
In the Project explorer view, all the projects are going to look like they live at the root level. However you can group related projects into working sets. Then select just the working set you're interested in and all the others will disappear from view.
A warning is in order if you make use of eclipse variables in external tools (and possibly elsewhere). The syntax you use for paths needs to be adjusted. For example with projects outside the workspace this syntax ${workspace_loc:/MyProject/MyFile.txt} is no longer the same as this syntax ${workspace_loc}/MyProject/MyFile.txt
See these two images of eclipse project explorer below. The first one has dotted lines (so it's much easier to see the hierarchy), while the second one does not (which is the case for the eclipse on my computer).
How to configure eclipse 3.6 on Windows 7 to display dotted lines?
Windows 7 removed this tree-view component from application usage, you can read about it here.

In otherwords, you can't add it back, but that link provides a modification which they claim helps out a bit.
It was called "Simple Folder View", you can read about how it was turned on/off in Vista.

You can make the whole app go back to an XP like look by disabling visual themes on the compatibility settings. See: https://stackoverflow.com/a/8973912/381161
