Countless times i have needed to put a quotation marks around text during programming. I remember awhile ago that i have seen someone selecting text and simply do magic with the keyboard shortcuts and putting quotation marks around it. How to do so?
In eclipse
1. Window -> Preferences -> Java -> Editor -> Templates
2. Click on "New"
3. Type "quote" for name (you can name it whatever you want)
4. In the pattern box, enter "${word_selection}"${cursor}
5. Click ok
6. Click apply and close preferences
7. Select the string you want quoted, press CTRL + <space> and type quote

I tried to get Eclipse to convert all of the tabs in my project to spaces like this:
Java Editor:
Click Window » Preferences
Expand Java » Code Style
Click Formatter
Click the Edit button
Click the Indentation tab
Under General Settings, set Tab policy to: Spaces only
Click OK ad nauseum to apply the changes.
And now my code is formatted without any indentations within if and for blocks, like this:
private void addAppointment(Resource resource) {
if (resource != null) {
Appt appt1 = new Appt();
appt1.setTime(new Date());
resource.setAppointment(appt1);
}
}
I really don't want to have to manually fix this in the hundreds of files in the project, how can I format to indent within if and for blocks in the whole project?
I should also say that the "Statements within blocks" checkbox in the active Formatter profile is checked. The preview it shows has a for block with an indented body, so I have no idea why that isn't being applied to my project.
#gnac provides some good options, in addition to:
Similarly you can use ctrl+shift+f (Source->Format) on each class to format it on the fly
You can select the project(s) and do Source menu -> Format to format everything in that project in one go. (No keyboard shortcut for it AFAIK.)
So once you set your formatting options you have a couple of options. You can set the preferences to format your files when saving.
Preferences->Java->Editor->Save Actions
However, if you have a lot of files this will be a pain as well. Similarly you can use ctrl+shift+f (Source->Format) on each class to format it on the fly, again having to do it on each file individually.
Inside Eclipse you can use Search->Find, enter "\t" in the text box and select the "Regular Expression" check box and then click the "Replace..." button. When the search is done, it will ask you what to replace it with. Enter 4 spaces into the "With" text field. Click Preview to see what it will do, or OK to make the changes.
I would use a find and sed to find all of the java files in a directory and replace the tabs, although this is outside of eclipse
find -iname ".java" -exec sed -i.orig 's/\t/ /g' {} +
If you're not on Linux you could use cygwin to do the same on Windows.
is there an option or plugin for eclipse which would enable multiple simultaneous selections in the same editor.
In sublime text, selecting some text and then pressing Ctrl+d will add next instance of the same text to the selection if possible. After selecting the instances needed the editor has multiple carrets (not necessarily on the same or adjacent columns and rows). In this mode it is possible to move all cursors forward or back simultaneously and to edit all instances of text simuntaneously.
I find this feature very usefull and miss it sorely in eclipse..
This Eclipse plugin attempts to provide this feature: https://github.com/caspark/eclipse-multicursor. From the README:
What is this?
A work-in-progress attempt to provide Sublime-Text-like
multi cursor support for text editors in the Eclipse IDE.
What works?
Multiple identical lines can be edited simultaneously using Eclipse
linked mode editing (similar to existing "rename in file"
functionality)
Next steps
"select next" functionality + associated editing using Eclipse linked
mode
"find next" + associated editing
editing of non-identical text / editing without using linked mode
split selection to lines
regexp support for find next
This feature is available in LiClipse.
See it in action (more towards the end of the video).
It supports linking with Ctrl+K, unlink with Shift+Alt+K, Ctrl+Alt+mouse double click to select words or Ctrl+Alt+Mouse to make a selection of a region (or just end lines).
Preferences>General>keys>Rename - refactoring
I changed the binding to command + shift + R when > Editing Text.
Sorry for bringing up an old question, stumbled upon it after searching google for the problem
Alt + Shift + A, then you can hold shift and use the cursor in multiple lines.
Like Ctrl+D I could not find, but like Alt+F3 in sublime (multiselects all matches), you can do by pressing Alt+Shift+R, or select text > right click > refactor > rename.
Must say that this does not work with any kind of text. It works with names of variables, functions, classes etc.
Tested on Eclipse 3.8.1
ALT + SHIFT + F worked for me.
You can see shortcuts for all here:
Goto -> Window -> Preferences -> General -> Keys and search for replace then you will see binding for Find and replace. In the bottom of that window, you can add your key to Binding text box. There you can add or edit any keys as shortcut.
If you want to replace selected word's matching words or find selected words, use below keys because you do not need to select all words in eclipse:
Ctrl+F gives me Find/Replace dialog box.
Or you can,
First Alt+A
Next Alt+F
Then press on Replace or Search button occurding to your need.
I have many source code files which are idented with 8 space characters, I want to convert these to 4 character indents. What is the best way of doing this? A technique using eclipse would be preferable.
Select the project(s), then press Ctrl+H to open the Search dialog (or click the Search > File menu).
Make sure the File Search tab is selected at the top.
Enter 8 spaces into the Containing text: field
Select your File name pattern (probably *.java or just *)
Select the scope (probably Selected Resources)
Press the *Replace... button.
As I said in the comments above, however, using spaces for indentation is a fool's game; tabs are the proper abstraction for indentation so that you don't have this problem.
A few days back I felt this question to be dumb and dint post it here, but after even after searching a lot I dint find a proper solution.
For those of you who used TextEdit (on Mac), they will perfectly know what I am talking about.
While coding I just want to put quotes or parentheses over a word or a line.To do this I'll have to move back to the starting of the word, open the quote and then go to the ending of the word and close it.
Is there a plugin or so in eclipse where I can just surround the current selection with quotes or parenthesis ?? I am not talking about quick fix (Ctrl + 1). It can be used for much complex templates.
You can do that with a custom template, so for example if you want to create this template for java, you can do :
Preferences ---> Java ---> Templates
Create a new template and call it quote, then type this as pattern :
"${word_selection}"${cursor}
Save it and Apply.
After that you can use that template selecting the text you want to quote then press CTRL + SPACE and then chose quote.
Same thing for parenthesis :
(${word_selection})${cursor}
Eclipse is a great editor, and among it's many wonderful features one of my favorites is the Mark Occurrences feature. However, I recently installed the Aptana plug-in, and in trying to configure it I somehow managed to break Mark Occurrences in my Eclipse installation.
The feature still works somewhat, but instead of highlighting all occurrences of a given object, it now only highlights the occurrence where it is first created. In other words, in:
1. Dog dog = new Dog();
2. dog.bark();
3. dog.bark();
Only the "dog" in line 1 would be highlighted, not the "dog" in 2 or 3.
However, before I know I had things configured such that all three "dog" references would be highlighted by Eclipse. Does anyone know what configuration option I changed to "break" the marking of occurrences like this?
If the option mentioned by laurie is checked and you're wondering why it isn't working, you might have hit Alt-Shift-O sometime:
Cannot highlight all occurrences of a selected word in Eclipse
Note, that "Organize Imports" has Ctrl-Shift-O...
Check the following preference setting:
Preferences > General > Editors > Text Editors > Annotations
In here compare the settings for Occurrences and Write Occurrences.
You probably don't have the Text as higlighted option checked
There is another way to toggle the Mark Occurrences feature (apart from Preferences -> Java -> Editor -> Mark Occurrences)
Simply click the "Toggle Mark Occurrences" button from the toolbar. This can be seen in the image below. If you don't see the item in your bar you can turn on by selecting Window > Perspective > Customize Perspective... > Editor Presentation > Toggle Mark Occurrences
You can use a keyboard shortcut to toggle it, also:
On Windows: Alt + Shift + O
On OS X: Option + Command + O
Hope that helps
Preference > Java > Editor > Mark Ocurrences > check: Mark Ocurrences of the selected element in the current file.
and eclipse won't highlight occurences if your project contains errors
check the Problems view to be sure you project is clean
Go
Java> Editor > Mark Occurrences
Uncheck "Keep Marks when the section changes" then click Ok
Restart Eclipse.
This work for me.
Double click on the class or the package in it disappears. Have no fear.
( I also activated this feature by mistake while pressing selecting a word)
