I've searched for answers to this problem for days now, and still no solution.
The problem is: I work with eclipse and pydev in linux environment and in the overview ruler I only see lines that represent function definitions and imports, all other text in my .py file (or any other file for that matter) is now shown.
I tried to see annotations and other properties and that does not change a thing.
I'm adding a picture with the problem:
Well, the issue is that this feature is not currently implemented in PyDev. The overview ruler as it is is not a real minimap. It only shows entries for what would be outline entries (not a minimap for the code).

I just moved a Python project into Eclipse, and I don't understand what this column (encircled in red) is trying to indicate to me:
I get that the blue rectangle is a sliding window that corresponds to the code section currently in the window, but what do the grey lines mean?
Other Information:
- I have used previous versions of Eclipse and PyDev and haven't seen this before. Even now, I only see it when I open a open a PyDev project. I assume it's some option associated with the PyDev perspective, but I can't find any option in the Customize Perspective menu for it.
- I have looked through several Eclipse tutorials and help files, and can't find any other examples of it.
- The grey lines don't seem to correspond to function calls, indentation, docstrings/comments, or any other code trait that I can think of.
- I am using Eclipse 4.3.1 (Kepler) with PyDev 1.0.0.9.

I recently brought Mac Book Pro and I installed Eclipse Luna. I am facing a problem in viewing the Java projects in "Package Explorer" folders are very small. Is there a way to increase instead of changing the screen resolution?
It should be possible, have a look at this link: http://blog.vogella.com/2013/02/19/css-styling-individual-part-of-the-eclipse-ide/
(Copy of the essential part, in case the above link stops working:
#org-eclipse-jdt-ui-PackageExplorer {
font-size:20;
background:black;
}
)
Remains the question, where to put those lines. Best would be to create your own style, but I never figured out how to do it. So I usually just modify one of the built-in styles. To do this, go to /Applications/eclipse4.4/plugins/org.eclipse.ui.themes_1.0.1.v20140819-1717/css and open the css-file of the style you currently use (probably e4_default_mac.css). Then add the above lines at the end of that css file and restart Eclipse. Note: when updating Eclipse, you might have to repeat those steps.
EDIT: Just realized it was already asked and answered on SO: I cannot change the font size of package explorer in Eclipse Don't look at the accepted answer, but at the next one below.
No, there is no way to change the size of folders or other visual properties of package explorer.
The views, fonts, etc... of general views are set by the system/OS properties. Only the editor view allows customization of sizing, such as, font.
I am trying to develop an eclipse plugin that does some documentation check on java code and highlights some lines of code in the editor.
To achieve my goal, I DON'T want to create a new editor in eclipse, I simply want to extend the default java editor to draw a line under (or highlight) the methods that do not satisfy some set of predetermined requirements.
Do I need to create a PresentationReconciler? If yes, how do I make the JDT or workbench use my reconciler.
I have never done plugin development and this is my first attempt.
Several starting points for you:
Annotations are an UI feature of JFace's text editor that allows you to visually mark some places in an open editor.
Markers are a Workbench feature, more high-level. They are generic "objects that may be associated with Workbench resources", and they can display in several places: in text editors (as annotations) or in the Problems view, for example.
Depending on what you want to do, you would plug in your plug-in into extension points related to either of those.
The Eclipse Java editor is located in the org.eclipse.jdt.internal.ui.javaeditor.JavaEditor package.
The "internal" in the package name means that the Eclipse development team can change how the Java editor works with new revisions.
Try this help page: Juno Help on syntax highlighting
At the end of the page, it describes how to dynamically add a PresentationReconciler, which is used for syntax highlighting. See if that fits the problem that you want to solve.
I assume you already have a plugin project.
In your plugin.xml, open the tab Extensions, click Add..., search for org.eclipse.ui.editors, then you should see a template named Editor, which will produce a simple xml editor to experiment and play with. Also, you will be able to see the needed structure to define a custom editor.
Hope this helps...
I don't know if you still have a need for this, but you are going to want to use Annotations to keep track of what parts of the editor you need to highlight.
For actually doing the graphical effect of highlighting, you could do syntax highlighting via a PresentationReconciler, but I have no experience with that.
We used a technique we borrowed from http://editbox.sourceforge.net/, replacing the background image of the editor Shell. Its open source, so check it out. (Our code might also help -- its at https://github.com/IDE4edu/EclipseEditorOverlay )
One of the features I really like about Netbeans is that when you click on a variable, method, field etc. Netbeans shows you all the usages of this entity in the right hand bar as little bars of colour. Is there a way to get this behaviour in IntelliJ IDEA and if so, how do I turn it on? I haven't found anything in the settings or Google but I might be missing something!
file>settings or ctrl+alt+s (for windows) select editor from the list on the left and check Highlight usages of element at caret in the Highlight on Caret Movement section
Apart from enabling the "automatic highlight usages" setting described above, you can also invoke "highlight usages" manually, using the shortcut Ctrl+Shift+F7.
The benefits of using the "manual" highlight usages are:
You can highlight usages of multiple variables/methods/etc at the same time
You can remove highlighting for an individual element selectively, by invoking Ctrl+Shift+F7 again on that element
some users find it less distracting than "automatic highlight usage" - this is subjective or course
Above answers are correct but still to get the exact behavior like in Netbeans try to use Identyfier Highlighter plugin for Intellij Idea (available in default plugin list under window settings).
This is really strange as Idea features mentioned in previous answers would do the job if merged into the one configurable feature.
Is there a setting or plugin for eclipse that can show indentation guides in the editor? Something like the Codekana plugin for visual studio (not so fancy is also OK). Important that it works with PyDev.
EditBox since v0.0.20 is fixed for support Pydev. Thanks for reporting this. Some default preferences for Python included now, but you are welcomed to share yours here.
This can be achieved this is EditBox.
With some customization through it's preferences you can get to some nice code blocks highlighting of python code (or any other where blocks are signified with whitespace).
It is highly customizable and can achieve the vertical rules codekana style, and various other layouts.
The problem is it doesn't work on PyDev editor from what I see (at least for now). I've opened a feature request for it.
If it's any good, you can still view it's layout when opening a python file with right click "Open With/Text editor". From version 0.20, EditBox fully supports PyDev.
I also tried AnyEdit which has some whitespace highlighting amongst other features, but was not too happy with the results. For example, I had to press they're "show whitespace" button after each change to show the background, and it's not very visually pleasing (it uses eclipse's annotations to highlight whitespace).
IndentGuide is a plugin that does this for Eclipse. I am not sure whether it works for PyDev though.
The closest approximation would be to combine:
showing the whitespace characters (which shows tabs and spaces, but not just tabs)
code folding (available with PyDev)
