When I am checking the naming rules for my code. If i got variable or function name have more letters than allowed ERROR. I count the total character by manually or have to copy paste into Notpad++. Is there is any options to find the number of selected characters in eclipse.
Eclipse does not provide a way to display the length of a text selection like NotePad++.
Bug 73904: Show length of selection in status box was raised in 2004 (!!!) to add this feature but it still hasn't been implemented.
The good news is that someone has written a plugin named getStringLength to do exactly what you want, as mentioned in a comment in the Eclipse Bug Report:
Eclipse plugin that add the selected text counter on the right side of
the column and row position in the Eclipse status bar. After you
double click the text, this plug-in will show the length of text you
selected in the eclipse status bar; in the case you select more than
one row it will show the number of rows selected, like Notepad++ do.
The bad news is that I couldn't get it to work properly. After adding the plugin to Eclipse's dropins folder the status bar is updated as described, but the details are misaligned and not rendering correctly:
Through careful testing I can see that the plugin actually is updating the length of the selected text, but the entry on the status bar is practically illegible. Still, in the absence of anything else, it is worth trying - perhaps you will have better luck in your environment. Let us know if it works for you.
You don't need a plugin anymore with Eclipse 2019-09:
Editor status line shows more selection details
The status line for Text Editors now shows the cursor position, and when the editor has something selected, shows the number of characters in the selection as well.
This also works in the block selection mode.
These two new additions to the status line can be disabled via the General > Editors > Text Editors preference page.
i has fixed error rendering in eclipse version=4.12.0 on windows 10, with steps.
clone project (getStringLength project)
import to
edit file com.lyf.plugin.getStringLength.SelectedTextInfoControlContribution.java (line 26).
#Override
protected Control createControl(Composite parent) {
parent.getParent().setRedraw(true);
......
}
build plugin:
1. Right-click your plugin project in Package Explorer window.
2. Press Export... in shown context menu.
3. Select Plug-In Development -> Deployable plug-ins and fragments (or Deployable plug-ins and fragments directly in old Eclipses).
4. Close Eclipse. Copy this JAR to eclipse/plugins/ path. Run Eclipse again.
Good luck!
I have the same set of files in N folders, one of them, say, blank.xhtml. The files contain somewhat similar information and it is becoming overwhelming to figure out which file comes from which folder every time I switch between the tabs. When I open one of them to edit and happen to open a file with the same name from another folder I get confused and more often than not end up editing the wrong file: nullifying my hard work. So I am wondering if there is a way to show the name of a containing folder in the tab like this G-06/blank.xhtml or G-07/blank.xhtml. I will be very very thankful to anybody who has pointers to how I can make this happen.
As an addition to the Maroun's answer there is an alternative solution.
It's not exactly what you want (full name in the tab's title), but may be useful sometimes.
In the "Project Explore" view (the same goes to "Navigator" view) click the "Link with Editor" button. That way, whenever you choose some file opened in the editor, it will be automatically selected/highlighted (see the picture) in the "Project Explorer" view.
Here is the picture:
Maybe this will be useful to you too.
If you hover the mouse over the tab containing the file name then a popup appears showing the full path. Not exactly what you wanted, but it should help. (This with Eclipse Neon.3 Release 4.6.3 on a Mac).
Not quite what you're looking for, but ctrl+shft+e will open the switch editor window that shows all the open editors with their filepaths. I use this shortcut for the same reason. I'll have multiple build.gradle files open from multiple projects and this helps pick the correct one
In Eclipse, is there a way to have a Package Explorer like view that shows the classes without having to open the files individually.
I have this project where many classes are written in same files, and that makes navigating them so annoying. Is there some sort of ClassView in Eclipse that disregards file names.

This question is currently almost 2 years old, but for anyone ending up here through a Google search (like me):
Eclipse offers a "Java Browsing" perspective which is probably what you want. To see this, go to Window -> Open Perspective, and select Java Browsing.
You can use the Outline view.
Window > Show View > Other. Filter by the word 'Outline' (it's under General folder)
window->show view->outline was helpful for me as this was the only window missing in existing perspective.
Yes you can use F3 key if you're seeing this class, o you can use Ctrl+Shift+T shortcut to open 'Open Type' and write in it the name class
Okay, it's been asked a long time ago. You may be looking for the Breadcrumb. Searching for it and got this question. Suddenly I did it unknowingly and shared here. There is a button beside "Save", "Print" buttons; "Toggle Breadcrumb". :)
I can't seem to find a way in the options to display the full path of the file at the title of the tab. I can hover over it to see it, but it would be nice to see it at a glance.
There is a SU question about it also, https://superuser.com/questions/88637/netbeans-how-to-view-file-full-path-in-window-title-or-somewhere-else
Does anyone have a solution for this to actually display it? I can see there is a custom .jar for it in the RC2 Netbeans, but that's probably way old now.
PS, I should mention that a path relative to the project would be ideal, as well as a full path. Either really :)
NetBeans 8.0.2
Tools > Options > Appearance > Document Tabs > Show full file path
The full path will appear only for the active tab (under the tabs), but you can also check "Show parent folder name in tab title" if you want to see the parent folder for every tab:
Try to use following netbeans plugin.
In Netbeans 6.9.1 (at least) you can open the Window/Properties window and pin it under the editor; this will contain the full path in the "All Files" property which is then visible at all times and always contains the current editor file's properties.
Starting from NetBeans 6.9 you can use the NetBeans extention "show path in title":
http://plugins.netbeans.org/plugin/42000/show-path-in-title
it's very helpful :D
You can also 'Select in --> [Project|Files|Favorites]. This opens the exposes the node for the file in the Projects, Files or Favorites explorer.
To do this, right click in the text editor for the file you are interested in; the 'Select in' item is near the bottom of the menu that appears.
Try using CTRL+TAB, you can find the path in status bar. This is not complete solution for your question but using keyboard (without using mouse atleast) you can find the path of the open file(s).

I have been using Eclipse as an IDE for a short amount of time (about 3 months of full use) and almost every day I learn about some shortcut or feature that I had absolutely no idea about. For instance, just today I learned that Ctrl+3 was the shortcut for a Quick Access window.
I was wondering what your most useful/favorite Eclipse features are. With the IDE being so big, it would be helpful to learn about the more commonly used parts of the program.
My most commonly used features are
ctrl+1 quick-fix / spell-checker
opening files
ctrl+shift+t load class file by classname
ctrl+shift+r load any file by filename
matches are made on the start of the class/filename. start your search pattern with a * to search anywhere within the filename/classname.
Formatting
ctrl+shift+f Format source file
(set up your formatting style in Window | preferences | java | code style | formatter)
ctrl+shift+o Organise imports
Generated code
alt+s,r to generate getters and setters
alt+s,v to insert method signatures for overidden methods from superclass or interface
Refactorings
alt+shift+l Extract text-selection as local variable (really handy in that it determines and inserts the type for you.
alt+shift+m Extract text-selection as a method
alt+shift+i inline selected method
Running and debugging.
alt+shift+x is a really handy prefix to run stuff in your current file.
alt+shift+x, t run unit tests in current file
alt+shift+x, j run main in current file
alt+shift+x, r run on server
There are more. The options are shown to you in the lower-right popup after hitting alt+shift+x.
alt+shift+x can be switched for alt+shift+d in all the above examples to run in the debugger.
Validation
As of the recent Ganymede release, you can now switch of validation in specified files and folders. I've been waiting for this feature for ages.
Go to Project | Properties | Validation
click on the ... button in the settings column of the validator you want to shut up
Add a rule to the exclude group
code navigation
hold down ctrl to make all variables, methods and classnames hyperlinks to their definitions.
alt+left to navigate back to where you clicked ctrl
alt+right to go "forwards" again
This is cool: If someone has emailed you a stack trace, you can copy and paste the stack trace into Eclipse's Console window. You can then click on class names in the stack trace as if your own code had generated it.
In terms of actual features, rather than shortcuts, I strongly recommend taking a look at Mylyn.
It essentially skins Eclipse with a task focussed view. It tracks the files you touch when working on a task, and focusses many aspects of the UI onto the resources that it decides are relevant to the job in hand. Eclipse can be somewhat busy to look at, especially with a big multi module project, and Mylyn helps cut through the cruft. The connectivity to issue tracking software and source control repositories is also excellent.
In my experience, it polarises opinion amongst those who try working with it, which is probably a sign that it is offering something interesting... Don't mean to sound like a fanboy - it is definitely worth a look though.
A shortcut that I use everyday is Ctrl+K. In your editor (not only Java file), simply select a text (like a variable, a function, etc.), and then use this shortcut to go to the next occurrence of this text in the current editor.
It's faster than using the Ctrl+F shortcut...
Note also that you can use Ctrl+Shift+K to search backwards.
Ctrl-Alt (up/down) Copy selected line(s) above or below current line.
Alt (up/down) Move current (or multiple selected) lines up or down
Ctrl-Shift-R Bring up the resource window, start typing to find class/resource
Ctrl-O Bring up all methods and fields for the current class. Hitting it again will bring up all methods and fields for current class and super classes.
Ctrl-/ or Ctrl-Alt-C Comment single or multiple lines with //
Ctrl-Shift-/ Comment selected lines with /* */
Ctrl-. Take you to the next error or warning line
CTRL+PAGE DOWN / CTRL+PAGE UP to switch between opened editors
CTRL+E to also switch between opened editors (allows to type the name)
CTRL+O is extremely important for me. You don't longer need the Outline View then (you can close it which will give you more space). Then, you can type a method name or just the beginning of it and you quickly can get to it. I also use it to inspect what stuff is available. For example: CTRL+O and then type get ... now I see all getters.
F3 while an element is selected in the code: brings you to its definition or it's source. e.g. used on a method call it brings you into the source code of that method.
CTRL+M to maximize the current window
As already said, CTRL+3 is extremely good. It basically allows you to use Eclipse completely without a mouse. Just type CTRL+3 and then package explorer for example.
CTRL+F8 cycle trough perspectives
CTRL+L allows to type a line number and brings you directly to that line.
CTRL+SHIFT+G searches for all references to the selected element in the workspace.
And not a shortcut: In the project settings under Java Editor you can find Save Actions. This allows you to set up the project so that the code is automatically cleaned up and formatted when you save a file. That's very good it safes you from constantly pressing CTRL+O and CTRL+F.
Eclipse auto refresh isn't on by default so if you make changes to a file outside of eclipse, the change won't be reflected in your build. this is very annoying if you just did an svn/git update/rebase and things aren't working the way they're supposed to.
Turn it on in windows->preferences->workspace and tick Refresh Automatically.
Local History
It's a great feature. Eclipse has its own mini-CVS for all files in a project. If you want to revert some change you made, or even restore deleted file - you can right click on the project and select "Restore from Local History".
Just saved my ass *tears of joy*
CTRL+Shift+P to jump to the matching bracket/parenthesis.
One key feature: Shift+Alt+T for the refactoring menu.
Ctrl-shift-T, but only type the initial characters (and even a few
more) of the class you're looking
for. For example, you can type
"NetLi" to find NetworkListener
In the Search window, Ctrl-. takes you to the first leaf of a tree branch
Alt-/ is Word Completion. Slightly different from Ctrl-space
CTRL+SHIFT+X selected text becomes UPPERCASE
CTRL+SHIFT+Y selected text becomes lowercase
I'd like to add two additional shortcuts:
CTRL+F6 Switch between open editors (CTRL+SHIFT+F6 to scroll through the list in the opposite direction)
CTRL+F11 start program in debug mode
F11 start program in normal mode
A lot of the key bindings depend on the perspective and view currently active.
My most used ones for the Java perspective:
ctrl-shift-r open resource
ctrl-shift-t open type
ctrl-1 quick fix/refactor
ctrl-j incremental search
ctrl-h search in files (select a base directory and set scope to selected resources)
ctrl-o list methods
ctrl-alt-h open call hierarchy
ctrl-shift-l list shortcut keys
hit ctrl-shift-l again to go directly to preferences to change key mappings
I am also a fan of Eclipse, however since I spend a majority of my time in Visual Studio, I will suggest that you read Eric Sink's series of articles "C# to Java" (parts 1-4). Not only is Eric always an entertaining read, but this brief series covers some awesome Eclipse insight for those who have not been into Eclipse or have been away from it for a while:
From C# to Java: Part 1
From C# to Java: Part 2
From C# to Java: Part 3
From C# to Java: Part 4
Ctrl-Shift-M while the cursor is on a class name in your java file, will specifically add that and only that class to your imports. This is different from Ctrl-Shift-O which will not only add those imports not already defined, but will also remove imports not currently needed, something you might not necessarily want to do.
I forgot about [Ctrl+2 -> r] scope variable rename. Place the cursor in the variable you wish to rename, press Ctrl+2, then r, then type the new name watching all instances of that variable get renamed at the same time.
It's awesome at refactoring Hungarian Notation.
alt-shift-a is extremely useful in a few situations.
I use a lot of the above and also like for quick search: CTRL+J then type what I am looking for, then CTRL+K for next occurrence.
Lately I've been using the MouseFeeds plugin to automatically tell me what the key stroke combinations are. That way by repetition I remember them better.
This link has a better picture and description of what it looks like and does.
Shift+Alt+b for the simple navigation row over the editor.
I've just released this blog post about Top 5 Useful Hidden Eclipse Features. It contains:
Favorites: Types and members that will always show up in auto-completion
The awesome block selection mode: For multi-line editing
The EGit staging view: Much better than git itself
Type filters: To remove awt and java.lang.Object stuff from auto-completion
Formatter tags: To delimit code sections that shouldn't be auto-formatted
Alt+left and Alt+ right will navigate you forward and back.
I find the project-specific settings useful in Eclipse 3.3.
For example, if you have several developers working on a project who have different code styles for curly braces, line spacing, number of imports etc. then you can specify the style settings for the project. Then you can configure the save actions so that the code is automatically formatted when a file is saved. The result is everyone's code is formatted the same before it's checked in.
