I'm trying the Eclipse Auto Formatter, but I cannot find a proper options to format according to my liking.
When I have a line like this:
MyLongNameClass myLongNameObject = otherObject.callAVeryLongMethodWithParameters(param1, param2, param3)
Eclipse auto formatter wraps it this way:
MyLongNameClass myLongNameObject = otherObject
.callAVeryLongMethodWithParameters(param1, param2, param3)
I'd rather like to have this result:
MyLongNameClass myLongNameObject =
otherObject.callAVeryLongMethodWithParameters(
param1, param2, param3)
Keeping the object and the method accessor on the same line, and avoiding starting a new line with '.'. Is this possible? Is there an option for this?
I'm not sure if you can really do what you wanted, but this might get you close:
In eclipse Mars:
Go to Window -> Preferences -> Java -> Code Style -> Formatter
Create your own profile based on one of the built-ins using the New... button. By default this will take you into the editing window. If you already have a formatter set up that you want to change, select it and use the Edit... button.
In the profile editing window do the following:
Select the Line Wrapping tab
In the left scroll-box, go to Function Calls -> Qualified invocations.
In the Settings for qualified invocations area select Do not wrap.
In the left scroll-box, go to Function Calls -> Arguments
Select Wrap first element, others where necessary in the argument settings then select Indent by one.
You can test these settings by adjusting the line width in the preview window.
I know this is a late submission, but I hope it helps someone else who searches for this same feature.
Go to Windows -> Preferences -> Java -> Code style -> Formatter
You can create your own profile with customised formatting, you can also modify existing formatter.
Edit -> Line Wrapping
Explore line wrapping and change it accordingly.
Eclipse keeps auto formatting upon save, for example: it is insisting the following code should be in a single line once I save, despite breaking it up the way I want to.
#Transactional(rollbackFor = DataAccessException.class, readOnly = false, timeout = 30, propagation = Propagation.SUPPORTS, isolation = Isolation.DEFAULT)
Window > Preferences > Java > Editor > Save Actions.
Can also be configured at the project level. Project > Properties > Java Editor > Save Actions.
Absolutely maddening improvement. For if statements do the following:
Window | Preferences | Java | Code Style | Formatter | Control statements tab
Select Keep simple if on one line.
You might also try the Line wrapping tab
This is a Late answer, But just for novice to understand it clearly I have a snapshot of the setting.
Please follow the path on left.
And change highlighted setting.
If you wish to keep the auto-formatter, but don't want this behavior, you can also configure it in the fomatter :
right click on the project -> properties -> java code style -> formatter
(If you don't have a project specific formatter the global configuration can be accessed this way : Window -> Preference -> Java -> Code Style -> Formatter).
Edit... the active profile, open the Line Wrapping tab, and there check the Never join already wrapped lines option.
This way you can wrap lines wherever you want and eclipse won't remove your line breaks (which is a must if you wish to have readable lambda expressions), but keep the formatter active.
This option is there at least since eclipse Luna
Here is a screenshot where this option is :
Just wanted to add a tip. If you want to avoid the line wrapping you can simply increase the "Maximum line width" value to something enormous. As long as that is sufficiently high eclipse won't do any wrapping.
Preferences > Java > Code Style > Formatter > Edit > Line Wrapping > Maximum line width
Currently Eclipse only fold the java doc and at function level, but when reading long methods, there could be quite a lot of if/else etc, is there a way to fold them?
I found the Coffee-Bytes plugin. I downloaded it from this link and found this guide by the author, for using it.
You can find more details in these references:
What code folding plugins work on Eclipse 3.6?
How to use Coffee-Bytes code folding
in updated versions of Eclipse
Change folding preferences at:
Window -> Preferences -> C/C++ -> Editor -> Folding -> Enable folding of preprocessor branches (#if/#else)
Enable folding using ctrl + shift + /
No, in the Preferences Dialog (Menu Window/Prefernces): Java/Editor/Folding you may choose,
Comments
Head Comments
Inner Types
Members and Imports
if Enable Folding is checked.
If you wan't to do this because the blocks are so long that can't reconize the structure
you should consider to split if/else blocks into methods using Alt-Shift-M (Extract Method)
It appears Eclipse does not have built-in support for folding if/else statements but allows folding for other more complex cases like Anonymous inner classes. Try looking for plugins like this one (last modified 2007, try it if it supports your Eclipse version).
Ok, this is a little bit older, but maybe someone could find this useful:
In most cases you can surround the piece of code by an additional pair of scope brackets, and to remember what you folded you can add a line comment.
For example, if you want to collapse the following:
int SectionA_var1;
int SectionA_var2;
int SectionA_var3;
int SectionA_var4;
int SectionA_var5;
int SectionB_var1;
just add the brackets an the comment:
{ // SectionA
int SectionA_var1;
int SectionA_var2;
int SectionA_var3;
int SectionA_var4;
int SectionA_var5;
}
int SectionB_var1;
Then you get the (-) sign and you can collapse the whole section to this:
{ // SectionA[...]
int SectionB_var1;
No plugin necessary, and until now I had no situation where this gave me any downsides, except that you cannot use it on a top level declaration to collapse methods.
For now, there is built-in function.
Click "Window->Preferences->C/C++->Editor->Folding" and then enable appropriate option you want.
Apply, close and either refresh project or reopen eclipse.
As weird as it looks like, sounds like developers never thought about that. if you have a big if statement or any switch/loop ... just use notepad++ to be able to fold/unfold
For Python, i.e. Eclipse/PyDev, go to Windows > Preferences > PyDev > Editor > Code Folding and check all the boxes.
Fold java source code like "if else for" statement
install pluins com.cb.eclipse.folding
restart your Eclipse make sure the pluins enabled
Click "Window->Preferences->Java->Editor->Folding"
Select folding: select "Coffee Bytes Java Folding"
Switch to "User Defined Regions"
"Start Identifier" = { ; End Identifier = }
click "Apply and Close"
Reopen java source editor you will see "if" or "for" block is collapsable
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"
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.
