Is there a way to select a C/C++ expression in Eclipse and put a bracket around it with a single keyboard shortcut? IDEs usually have this but I couldn't find a way in Eclipse.
For Java Code, there is a more or less good workaround described in Parentheses over selected words in Eclipse, but this does not work for C-Code - after bringing up the template list for the selection, the suggested templates are empty.
As far as I know, exactly that is not possible. You might report it to Eclipse CDT as a feature request.
But as workaround a template like the following can be used:
(${line_selection})${cursor}
If you hit Shift+Alt+Z the Surround With Quick Menu shows all templates containing ${line_selection} and with a number key a templated can be selected.
The key Shift+Alt+Z can be changed, but unfortunately no key can be defined to select the template directly. Also unfortunately, this does not work for multi-line selections because everything in the template in the line before ${line_selection} will be applied to each selected line.
I use CUDA 8.0's version of nsight (Eclipse platform 4.4.0, CDT 8.4.0). My Eclipse C/++ formatter is configured to indent as follows (image is from the Formatter config prev:
but if I have this code:
and I press enter, get to the next line (the cursor is placed under the span), and type in an opening brace, it is not placed at the beginning of the line, but is rather kept indented:
Is this a bug or have I misconfigured something?
Notes:
I tried both the built-in formatter and the "CUDA C" formatter; they behave the same in this case
I see this behaviour in stock CDT as well. It looks like a bug. Please file a bug report.
I have installed the Checkstyle plugin for Eclipse. When i habe writen now a doc comment for a method and there is an empty line line between my acutal comment and the parameter list, like this:
/**
* A comment.
*
* #param param A param.
*/
void aMethod(String param) {
// some code
}
Checkstyle now complaints that there is an trailing space. And, although i didn't put a space at that postition there is an extra space...
..../**
.....*.A.comment\.
.....*.
.....*.#param.param.A.param\.
.....*/
It looks to me that Eclipse is adding this extra space to the docblock. How can i turn that off or configure the checkstyle plugin to ignore this extra space in a docblock?
I am supposing that you have already tried going to Window -> Preferences -> Java -> Code Style -> Code Templates -> Comments and ensuring that there is no trailing space for Constructors and so on.
I have had a lot of success with the Eclipse Plugin AnyEdit Tools. There is an option to removing trailing whitespace and another to Convert tabs to space, both of which will make Checkstyle much happier.

Reads: This is a long comment. I broke it into lines, but that made it impossible to edit without screwing up the formatting. Is there a way to make Netbeans add line breaks automatically?
As for today, the current NetBeans (7.3) word-wraps comments with some nice available extra options when formatting. NB: Unfortunately, this is currently only available for the Java language.
You can launch the formatter with the context menu→Format, or if you did not change the standard shortcuts, Alt+Shift+F should do.
To access the corresponding configuration: Tools → Options → Editor → Formatting; Language: Java; Category: Comments
Your IDE won't format the comment for you. You will have to do it by hand. Yes, that means you have to re-format it once you add new words to it.
If you press Enter to insert a new line, NetBeans will simply extend the docblock formatting - it won't break anything. There's also a useful option in the Preferences to display a line in the right margin, so you know when to break a line. It's in:
Tools > Options > Editor > Formatting > Right Margin
Is this what you're looking for?
Go to tools->options->editor->formatting
find line wrap and choose one the wrapping style you desire,there are two options : afterword and anywhere.
and then click OK! :D
nb : I suggest you to choose afterword
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

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.
