The question has two parts, one of which I already have the answer for.
How to auto-remove trailing whitespace from the entire file being edited? -> Answer: use the AnyEdit plugin, which can be set to do that on any save to the file.
How to auto-remove trailing whitespace only from the lines I changed? -> This I don't know and would appreciate any help.
I assume your questions is with regards to Java code. If that's the case, you don't actually need any extra plugins to accomplish 1). You can just go to Preferences -> Java -> Editor -> Save Actions and configure it to remove trailing whitespace.
By the sounds of it you also want to make this a team-wide setting, right? To make life easier and avoid having to remember setting it up every time you have a new workspace you can set the save action as a project specific preference that gets stored into your SCM along with the code.
In order to do that right-click on your project and go to Properties -> Java Editor -> Save Actions. From there you can enable project specific settings and configure it to remove trailing whitespace (among other useful things).
NB: This option has been removed in Eclipse Kepler (4.3) and following releases.
NB #2: The option seems to be back in Eclipse Luna - Luna Service Release 1a (4.4.1)
Removing whitespace from the entire file being edited:
Preferences -> Java -> Editors -> Save Actions -> check Perform the selected actions on save -> check Additional actions -> click Configure.. -> go to Code organizing tab -> check Remove trailing whitespace -> select All lines.
Removing whitespace only from the lines I changed:
Preferences -> Java -> Editor -> Save Actions -> check "Perform the selected actions on save -> check Format source code -> select Format edited lines.
Note it is not necessary to click Configure the formatter settings on the Formatter page - all the code styles automatically include removing trailing whitespace. At least I couldn't find a setting for this in Formatter configuration, and it worked out of the box for built-in Java Conventions, Eclipse, Eclipse 2.1 styles, as well as GoogleStyle.
When using this set-up, you obviously need to also turn off the solution to part 1 of the question.
Eclipse version checked: 4.5.2, 4.11
You don't need any plugin to do so. For instance, if you code JAVA, you can erase trailing whitespaces configuring save actions:
Eclipse 3.6
Preferences -> Java -> Editors -> Save Actions -> Check Perform the selected actions on save -> Check Additional actions -> Click the Configure.. button.
In the Code organizing tab, check Remove trailing whitespace
PyDev can do it by either Ctrl+Shift+F if you have code formatter option set to do it, or by during saving:
Eclipse -> Window -> Preferences -> PyDev -> Editor -> Code Style -> Code Formatter:
I use at least these:
Auto format before saving
Right trim lines?
Add new line at end of file
Do following:
Preferences -> Java -> Editor -> Save Actions
You can map a key in Eclipse to manually remove trailing whitespaces in the whole file, but only on request instead of automatically at save. (Preference/Keys and then map a set of keys to File/Remove Trailing Whitespace) This can be useful if you want to sanitize all new files, but keep legacy code untouched.
Another strategy is to activate visual display of whitespace, so at least you'll know when you're adding some trailing whitespace. As far as I know, there's no way to display only trailing whitespace though, but I'll be glad to be proved wrong.
In a pinch, for those editors that don't support removal of trailing whitespace at all (e.g. the XML editor), you can remove it from all lines by doing a find and replace, enabling regular expressions, then finding "[\t ]+$" and replacing it with "" (blank). There's probably a better regex to do that but it works for me without needing to install AnyEdit.
I would say AnyEdit too. It does not provide this specific functionalities. However, if you and your team use the AnyEdit features at each save actions, then when you open a file, it must not have any trailing whitespace.
So, if you modify this file, and if you add new trailing spaces, then during the save operation, AnyEdit will remove only these new spaces, as they are the only trailing spaces in this file.
If, for some reasons, you need to keep the trailing spaces on the lines that were not modified by you, then I have no answer for you, and I am not sure this kind of feature exists in any Eclipse plugin...
It is impossible to do it in Eclipse in generic way right now, but it can be changed given with basic Java knowledge and some free time to add basic support for this https://bugs.eclipse.org/bugs/show_bug.cgi?id=180349
The dependent issue: https://bugs.eclipse.org/bugs/show_bug.cgi?id=311173
For php there is also an option:
There is a really easy way to do this with sed, the Unix command line tool. You could probably create a macro in Eclipse to run this:
sed -i 's/[[:space:]]*$//' <filename>
As #Malvineous said, It's not professional but a work-around to use the Find/Replace method to remove trailing space (below including tab U+0009 and whitespace U+0020).
Just press Ctrl + F (or command + F)
Find [\t ][\t ]*$
Replace with blank string
Use Regular expressions
Replace All
extra:
For removing leading space, find ^[\t ][\t ]* instead of [\t ][\t ]*$
For removing blank lines, find ^\s*$\r?\n
I am not aware of any solution for the second part of your question. The reason is that it is not clear how to define I changed. Changed when? Just between 2 saves or between commits... Basically - forget it.
I assume you would like to stick to some guideline, but do not touch the rest of the code. But the guideline should be used overall, and not for bites and pieces. So my suggestion is - change all the code to the guideline: it is once-off operation, but make sure that all your developers have the same plugin (AnyEdit) with the same settings for the project.
I used this command for git: git config --global core.whitespace cr-at-eol
It removes ^M characters that are trailing.

On saving a plain-text file in the Eclipse standard text editor (NB: This is not about Java files!), Eclipse removes trailing whitespace of all lines.
Is there a way to suppress this behavior? I could not find any option for this.
You can just go to Preferences -> Java -> Editor -> Save Actions and configure it not to remove trailing whitespace.
I am trying to detect extra newlines between two methods in my code.
How can I detect all of them with RubyMine? For example:
def some_method
end
# two new lines
def other_method
end
Edit -> Find -> Find in Path
Set "Text to find" to
end\n\n\n
Check "Regular expression"
click Find
There might be spaces before any of those newlines, so you might find more matches with
end *\n *\n *\n
You could also consider removing extra newlines automatically by reformatting your code:
make sure that Preferences -> Project settings -> Code Style -> Ruby -> Other -> "Blank lines around methods" is set the way you want (and all the other Ruby code style settings are the way you want)
in the project page, select the parent directory of all of the files you want to reformat
Code -> Reformat Code...
hit Run
Of course you would only do this if you were prepared to reformat everything.
Need to keep EOL format consistent in all resources under Eclipse workspace.
I know about Eclipse preference that sets new line style for newly created files, but I would like to have automatic conversion for already existing files. Is there some settings/plugins?
I want just setup once and be sure that all line endings are in the same format.
In addition to the Window > Preferences > General > Workspace setting for new files that you already know about, there is a File > Convert Line Delimiters To option. I don't know of any existing plugin/tool that will do this automatically when you save, but you could certainly write one or make converting the line ending part of your process.
To make it easier on yourself, you can bind keyboard shortcuts to the conversion commands by going to Window > Preferences > General > Keys and filtering using "delimiter":
In Eclipse, to convert the line endings for existing files:
Go to the file browser view, and click on the project/folder/file that you wish to convert.
From the menu bar, select File > Convert Line Delimiters To > Windows / Unix / MacOS 9.
You can Search your resources with the Search-Dialog and go to the tab File Search. There you can enter a Regular expression. Enter \r\n or whatever line ending you want to change.
Then hit the Replace .. Button instead of Search.
I want just setup once and be sure that all line endings are in the same format.
... ok, my answer does not consider this.
You might get usefull results with Eclipse save actions: If the eclipse formatter also converts the EOL style, you could use it to modify EOL style only for the files you are modifying.
Unfortunately I don't have eclipse here, so I can't test if this actually works. Worth a try, however.
I just started to use NetBeans, and am trying to work out how to:
Make it so that trailing whitespace is removed on save. I know that you can invoke it manually, but it’s annoying if you forget. Can it be done automatically on save? I want this done because it keeps the code neat, because it’s really annoying when you’re moving through code and the text cursor goes all over the place because of trailing whitespace you don’t see, and because trailing whitespace has unintended effects on HTML layouts and other stuff.
Make it so that tabs are automatically made into 4 spaces while you’re typing rather than converting on save, or, worse, only when manually invoked.
For the first question, NetBeans 7.0+ has now a built-in solution. You can find it in:
On NetBeans 7:
Tools > Options > Editor > General > When saving files > Remove Trailing Whitespace: Never / Always / For Modified Lines Only
On NetBeans 8 / 9:
Tools > Options > Editor > On Save > Remove Trailing Whitespace From: None / All Lines / Modified Lines Only
[Original] For your first question, how to set NetBeans to remove trailing whitespace, the answer is that there is no setting (at the moment) to control that. It happens automatically, but not to every line. Whitespace is only removed from the lines you edit (or from the entire file if invoked manually). See Petr Pisl's blog entry titled "Removing trailing spaces" for a more complete explaination. (Note that even though he is blogging about NetBeans' PHP features, this particular feature applies to the basic editor shared by all NetBeans supported languages.)
[Update] This feature has been made available as of version 7.0, as pointed out by others in comments and answers below.
For your second question, set the editor to automatically make tabs into spaces as you type, you can find that setting in the Editor Formatting options:
Click on the Tools menu, and choose Options
Click on Editor in the top row of icons
Click on the Formatting tab
In the Language field, ensure that All Languages is selected
In the Category field, ensure that Tabs And Indents is selected
Check the box for Expand Tabs to Spaces
For each additional language that is available in the Language field, check that either Override Global Options is not checked, or that Expand Tabs to Spaces is also checked for that language.
Click OK
That will make sure that when you hit the tab key the specified number of spaces is inserted rather than a tab character. As above with whitespace removal, any existing tabs in the file are left as-is unless you invoke the manual command to change the entire file. (Moreover, even if you edit a line with tabs on it--leaving the tabs in place--the editor will not convert them to spaces. Only new instances of hitting the TAB key are controlled by this option.)
Tools > Options > Editor > On Save > Remove Trailing Whitespace From: None / All Lines / Modified Lines Only
This is as of Netbeans 7.3, according to Webmut.
For netbeans 7.4+
Windows - Tools > Options > Editor > On Save > Remove Trailing Whitespace From: None / All Lines / Modified Lines Only
Mac - Netbeans > preferences > Options > Editor > On Save > Remove Trailing Whitespace From: None / All Lines / Modified Lines Only
Also you can set this as language specific.
You can also set reformat while saving.
if you want to remove all trailing spaces in the file manually ONLY ONCE, you can invoke action 'Remove Trailing Spaces' from Source menu manually.
Source -> Remove Trailing Spaces
This is a simple question :
Is there any automatic indentation alignment on Eclipse PDT when you do a copy-paste ?
Because it doesn't work on my installation (raw copy-paste), but maybe this is because I use tabs instead of spaces, so I want to know if it will work if I switch to spaces.
Thanks
Actually, such a function exists now for eclipse CDT. In preferences : C++ -> Editor -> Typing, "when pasting", "adjust indentation".
Perhaps it is the same for PDT ?
I don't know specifically about PDT, but normally you can indent code with Ctrl + i, and format code with Ctrl + Shift + f (under Preferences -> Java -> Code Style -> Formatter you can specify how the formatter should work).
You can even select multiple files in the navigator and select Source -> Format to format several files then.
Tony Vermeiren had a suggestion that worked for me
(from https://bugs.eclipse.org/bugs/show_bug.cgi?id=351771#c17)
open workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.php.ui.prefs
add "smartPaste=false" at the end
save & restart eclipse
A similar idea to Davids is the use of Save actions: in the Preferences selecting Java/Editor/Save actions you can define an action to format the java code files during saves. It would solve the paste format problems during the save.
If you manage codes with different coding standards, where this formatting might have problems, define multiple formats, on a per-project basis (using the Project properties window).
Ok then I guess the answer is : no, this functionnality doesn't exists yet. I've moved to PhpStorm and I'm more than happy.
TLDR: uncheck "C/C++->Editor->Typing->Adjust indentation"
Explanation:
When i copy paste the following:
And "C/C++->Editor->Typing->Adjust indentation" checked
The result is that the second line has unwanted indentation:
To fix this just uncheck "C/C++->Editor->Typing->Adjust indentation"
