Eclipse Code formatter: keep complete function signature in one line - eclipse

how is it done? cant find the option?
why is it anyways, that so many people format their code that way?
i really dont like it...
int
foo(int); //dont like
int foo(int); //like


By default, Eclipse shouldn't be reformatting your code unless you have it do so through the Format command.
However, if you're working with other people's codes and want to format it to your liking it is possible to have Eclipse apply formatting.
You can adjust how this works by locating the Code Style section under the language you are using under the Preferences menu.


Start with the Window->Preferences menu. I like to type "code" into the search box to limit the options. Then follow the steps in the image ** You can format almost everything.
I can't answer why some people would like the return value on a line by itself; I've never met anyone that did.

How to auto-uppercase MySQL after typing keywords?

I type pretty fast so I want MySQL Workbench to auto-capitalize keywords after I type them. I've seen a solution to a similar question which is MySQLWorkbench-> Preferences-> Query Editor-> Change keywords to UPPER CASE. However this only provides uppercase for autofill. The problem is that the dropdown menu takes a second to load and hinders my work flow.
Is there any solution to this problem? Could I create a trigger for this or is that not helpful?

Not an automatic solution but something useful: look in the Edit -> Format menu. It has entries to upcase + downcase keywords, as well as other formatting commands.

Is there way to change NON-NLS tag itself to something else?

In Eclipse Kepler I started externalizing strings and the wizard puts the NON-NLS behind the lines. I know the reasons why and that's great, but is there way to modify this tag to be something else?
For example for code style you can use tags to enable and disable the formater and you can define your own and I prefer much shorter ones.
If instead:
//$NON-NLS-1$
I could change it to for example something like this:
//$NX-1$
And still being properly detected by the Source -> Externalize Strings wizard.
For me it would improve my readability, it makes big lines, then it wraps them where they didn't needed to etc... And I can make sure not use NX prefix on anything else so it will not misbehave.
Is there setting/plugin/workaround which could achieve desired effect?
Thanks in advance for any hints.
UPDATE: Marked answer didn't solved it per say, because looks like mine question doesn't have solution (maybe except recompiling eclipse)

You can edit the template in preferences.
Go Window > Preferences > Java > Editor > Templates the editor nls template.
Change current template from //$$NON-NLS-${N}$$ to //$$NX-${N}$$ or some thing else you want.

Eclipse - custom quick fix - Add some text before and after selection

I could use a dummy guide or directions how to add a custom quick fix or if it is even possible.
Let's say I select a text inside code - "foo foo". Now I want to add something before that text and something after. The content before and after remains the same across many files and it has to be done manually.
Is there a way I could write my own quick fix in eclipse, which would add this text automatically.
Ctrl + 1 -> "Add ... before and ... after" -> And get the desired output?
This seems somewhat useful if not the correct thing, but I can't exactly read out how to accomplish this: FAQ How do I implement Quick Fixes for my own language?
Any easier explanations and guides are appreciated. Or what other ways would I have to accomplish this desired behavior without typing/copying repetitive things
Edit: Found this little macro thing which is one way to solve my problem. start with cut, write, paste and end macro. But I'm not sure if this is the best way. Practically Macro

I suggest this solution that allow you to get the result using Eclipse search.
CTRL+H to do a search and choose Files Search
Fill Containing text with "foo foo". Tweak other parameters to get the files you want
Check Regular expression
Click on Replace
Fill With: <prefix>$0<suffix>. For example if you want to substitute "foo foo" with "this is a foo foo example" write this is $0 example
Check Regular expression (if unchecked).
Done. I think that this solution is quite flexible (as long as you are familiar with regexp to get desidered strings) and easy to apply.

Eclipse: Automatic line wrapping to specified width

I'd like for my lines, especially within comments, to be automatically managed so they don't get too long.
I remember once I had a configuration for vim which automatically moved the word I was typing to the next line once I reached 72 characters. It wasn't smart enough to rearrange the paragraph if I edit it, but it was a start.
Is there something that can manage these for me? I have a tendency to write really long comments in my code, and it helps to make them look neat by having consistent width, but it's always a pain to do this because oftentimes editing a sentence requires editing the entire rest of the paragraph.
I have just recently discovered the Ctrl+Shift+F feature. It is amazing and superior to Ctrl+I which is what I was using up till now, but I noticed that it does not do anything to clean up my comments.
Update: The answers are correct when working with Java in Eclipse. It seems like I have to wait for the CDT to incorporate this feature.

In "Windows -> Preferences", go to "Java -> Code style -> Formatter" to customize the formatter (called when you click Ctrl+Shift+F). In the tab "comment", you can set the maximum line width for comments (it can be different then the line width for code).
Tip: in the preferences, "Java -> Editor -> Save actions", you can make Eclipse to automatically format your file when you save it, so your code is always correctly indented !

The automatic formatting of Eclipse great no question.
If your comments are reformatted depends on what comment type and how you already have inserted line breaks.
Writing for example one very long line comment starting with // will be broken down by the formatter into multiple lines.
However you later edit the formatted lines - e.g. delete parts of it the formatter will leave them as they are. Only over-long lines will be changed.
Just in difference to block comments like this: /* comment */
Those comments will always be re-formatted in case the line is too short or too long.

If you want to format your header comment, you have to check Enable header comment formatting - that was the trick for me.
Obviously, to use this, you must create new formatter profile.

How do you display code snippets in MS Word preserving format and syntax highlighting?

Does anyone know a way to display code in Microsoft Word documents that preserves coloring and formatting? Preferably, the method would also be unobtrusive and easy to update.
I have tried to include code as regular text which looks awful and gets in the way when editing regular text. I have also tried inserting objects, a WordPad document and Text Box, into the document then putting the code inside those objects. The code looks much better and is easier to avoid while editing the rest of the text. However, these objects can only span one page which makes editing a nightmare when several pages of code need to be added.
Lastly, I know that there are much better editors/formats that have no problem handling this but I am stuck working with MS word.

Here is the best way, for me, to add code inside word:
Go to Insert tab, Text section, click Object button (it's on the right)
Choose OpenDocument Text which will open a new embedded word document
Copy and paste your code from Visual Studio / Eclipse inside this embedded word page
Save and close
Advantages
The result looks very nice. Here are the advantages of this method:
The code keeps its original layout and colors
The code is separated from the rest of the document, as if it was a picture or a chart
Spelling errors won't be highlighted in the code (this is cool !)
And it takes only few seconds.

Download and install Notepad++ and do the following:
Paste your code in the window;
Select the programming language from the language menu;
Select the text to copy;
Right click and select Plugin commands -> Copy Text with Syntax Highlighting;
Paste it into MS Word and you are good to go!
Update 29/06/2013:
Notepad++ has a plugin called "NppExport" (comes pre-installed) that allows you to copy to RTF, HTML and ALL. It permits dozens of languages, whereas the aforementioned IDEs are limited to a handful each (without other plug-ins).
I use Copy all formats to clipboard and "paste as HTML" in MS word.

After reading a lot of related answers, I came across my own solution, which for me is the most suitable one.
Result looks like this:
As you can see, it is the same syntax highlighting like on Stack Overflow which is quite awesome.
Steps to reproduce:
on Stack Overflow
Goto Ask Question (preferably with Chrome)
Paste Code and add a language tag (e.g. Java) to get syntax hightlighting
Copy code from preview
in Word
Insert > Table > 1x1
Paste code (you may need to use Paste Special... > Formatted Text (RTF) from the Edit menu to not lose the syntax hilighting)
Table Design > Borders > No Border
Select code > Edit > Find > Replace
Search Document ^p (Paragraph Mark)
Replace With ^l (Manual Line Break)
(This is required to remove the gaps between some lines)
Select code again > Review > Language > check "Do not check spelling or grammar"
Finally add a caption using References > Insert Caption > New Label > name it "Listing" or sth

There is a nice Online Tool for that : https://www.troye.io/planetb/
Just copy the generated code and paste it into your word editing software. So far I've tried it on MS Word and WPS Writer, works really well.
Doesn't play nice with Firefox but works just fine on Chrome (and IE too, but who wants to use that).
One of the main benefits is that, unlike the Code Format Add-In for Word, it does NOT mess with your code, and respects various languages' syntax.
I tried many other options offered in other answers but I found this one to be the most efficient (quick and really effective).
There is also another online tool quoted in another answer (markup.su) but I find the planetB output more elegant (although less versatile).

I type my code in Visual Studio, and then copy-paste into word. it preserves the colors.

When I've done this, I've made extensive use of styles. It helps a lot.
What I do is create a paragraph style (perhaps called "Code Example" or something like that) which uses a monospaced font, carefully chosen tabs, a very light grey background, a thin black border above and below (that helps visibility a lot) and with spelling turned off. I also make sure that inter-line and inter-paragraph spacing are set right. I then create additional character styles on top (e.g., "Comment", "String", "Keyword", "Function Name Decl", "Variable Name Decl") which I layer on top; those set the color and whether the text is bold/italic. It's then pretty simple to go through and mark up a pasted example as being code and have it come out looking really good, and this is works well for short snippets. Long chunks of code probably should not normally be in something that's going to go on a dead tree. :-)
An advantage of doing it this way is that it is easy to adapt to whatever code you're doing; you don't have to rely on some IDE to figure out whatever is going on for you. (The main problem? Printed pages typically aren't as wide as editor windows so wrapping will suck...)

Maybe this is overly simple, but have you tried pasting in your code and setting the font on it to Courier New?

Try defining a style called 'code' and make it use a small fixed width font, it should look better then.
Use CTRL+SPACEBAR to reset style.

If you are using Sublime Text, you can copy the code from Sublime to MS Word preserving the syntax highlighting.
Install the package called SublimeHighlight.
In Sublime, using your cursor, select the code you want to copy, right click it, select 'copy as rtf', and paste into MS Word.

I'm using Easy Code Formatter. It's also an Office add-in. It allows you to select the coding style / and has a quick formatting button. Pretty neat.

In case you're like me and are too lazy or in a hurry and don't want to download additional software, you can use http://markup.su/highlighter/. It's very straight forward and supports several highlight themes and many programming languages. In my case I was using Visual Studio Code, which doesn't allow copying with format due to CSS involved in styling (as reported here).
Copy the text from the Preview box and then in Word go to Insert -> Textbox, paste the Preview from the website, highlight all the text, and then disable spell checking for that textbox.
This is what the code looks like finally.

The best way I found is by using the table.
Create a table with 1x1. Then copy the code and paste it.
If you're using the desktop app then it will inherit the code editor theme color and paste it accordingly, else you can change the table style to any color.
UPDATE ------------------
From Word 2021, you can directly paste the code and it will preserve the formatting. No need to create the table.
Thank you #RdC1965 for mentioning this.

This is a bit indirect, but it works very nicely. Get LiveWriter and install this plugin:
http://lvildosola.blogspot.com/2007/02/code-snippet-plugin-for-windows-live.html
Insert your code using the plugin into a blog post. Select all and copy it to Word.
It looks great and can include line numbers. It also spans pages decently.

Vim has a nifty feature that converts code to HTML format preserving syntax highlighting, font style, background color and even line numbers. Run :TOhtml and vim creates a new buffer containing html markup.
Next, open this html file in a web browser and copy/paste whatever it rendered to Word. Vim tips wiki has more information.

In my experience copy-paste from eclipse and Notepad++ works directly with word.
For some reason I had a problem with a file that didn't preserve coloring. I made a new .java file, copy-paste code to that, then copy-paste to word and it worked...
As the other guys said, create a new paragraph style. What I do is use mono-spaced font like courier new, small size close to 8px for fonts, single spaced with no space between paragraphs, make tab stops small (0.5cm,1cm,..,5cm), put a simple line border around the text and disable grammar checks. That way i achieved the line braking of eclipse so I don't have to do anything more.
Hope I helped ;)

This is the simplest approach I follow. Consider I want to paste java code.
I paste the code here so that spaces, tabs and flower brackets are neatly formated http://www.tutorialspoint.com/online_java_formatter.htm
Then I paste the code got from step 1 here so that the colors, fonts are added to the code http://markup.su/highlighter/
Then paste the preview code got from step 2 to the MS word. Finally it will look like this

You can use VS code to keep code format and highlighting. Directly copy and paste code from VS.

you can simply use this Add-in on any office program.
Go to insert tab, then Get Add-ins, and search for Easy Syntax Highlighter
It supports
185 languages and 89 themes.
Automatic language detection.
Multi-language code highlighting.

Use a monospaced font like Lucida Console, which comes with Windows. If you cut/paste from Visual Studio or something that supports syntax highlighting, you can often preserve the colour scheme of the syntax highlighter.

Answer for people trying to resolve this issue in 2019:
Most answers to this question are outdated by now. I wish there was a way to reinspect old questions and answers every now and then!
The method I found for this question that works with Office 365 and its associated programs can be found here.

I'm using Word 2010 and I like copying and paste from a github gist. Just remember to keep source formatting!
I then change the font to DejaVu Sans Mono.
You can opt to copy with or without the numbering.

Copying into Eclipse and paste it in Word is also another option.

You can also use SciTE to paste code if you don't want to install heavy IDEs and then download plugins for all the code you're making. Simply choose your language from the language menu, type your code, high-light code, select Edit->Copy as RTF, paste into Word with formatting (default paste).
SciTE supports the following languages but probably has support for others: Abaqus*, Ada, ANS.1 MIB definition files*, APDL, Assembler (NASM, MASM), Asymptote*, AutoIt*, Avenue*, Batch files (MS-DOS), Baan*, Bash*, BlitzBasic*, Bullant*, C/C++/C#, Clarion, cmake*, conf (Apache), CSound, CSS*, D, diff files*, E-Script*, Eiffel*, Erlang*, Flagship (Clipper / XBase), Flash (ActionScript), Fortran*, Forth*, GAP*, Gettext, Haskell, HTML*, HTML with embedded JavaScript, VBScript, PHP and ASP*, Gui4Cli*, IDL - both MSIDL and XPIDL*, INI, properties* and similar, InnoSetup*, Java*, JavaScript*, LISP*, LOT*, Lout*, Lua*, Make, Matlab*, Metapost*, MMIXAL, MSSQL, nnCron, NSIS*, Objective Caml*, Opal, Octave*, Pascal/Delphi*, Perl, most of it except for some ambiguous cases*, PL/M*, Progress*, PostScript*, POV-Ray*, PowerBasic*, PowerShell*, PureBasic*, Python*, R*, Rebol*, Ruby*, Scheme*, scriptol*, Specman E*, Spice, Smalltalk, SQL and PLSQL, TADS3*, TeX and LaTeX, Tcl/Tk*, VB and VBScript*, Verilog*, VHDL*, XML*, YAML*.

If you are using Intellij IDEA, just copy the code from the IDE and paste it in the word document.

You can host one yourself since it is open source. The code is on github.

There really isn't a clean way to do it, and it could still look fishy based on your exact style settings.
What you could try to do is to first run a code-to-HTML conversion (there are many programs that do that), and then try to open up the HTML file with word, that might hopefully provide you with the formatted and pretty code, and then copy and paste it into your document.

I was also looking for it and ended up creating something for my code display.
Here's a good way:
Create a rectangular form and place your text inside.
Change the font to Consolas and size ~10.
Change the text font to gray near-black (gray 25%, darker 75%)
Use darker colors to highlight your text if needed and choose one to be the contour.

I have created an easier method using tables, as they are easier to create, manage, and more consistent (with the possibility to save the table's style inside the document itself), but I couldn't find a better way for code colouring scheme, sorry for that.
Steps:
Create a 3x3 table.
Select the table, and make its borders invisible ("No Borders" option), and activate "View Gridlines" option.
Make the adjustments to cells' spacing and columns' widths to get the desired aspect. (You will have to get in "Table Properties" for fine tuning).
Create a "Paragraph Style" with the name of "Code" just for your code snippets (as mentioned in https://stackoverflow.com/a/25092977/8533804)
Create another "Paragraph Style" with the name of "Code_numberline" that will be based upon the previous created style, but this you will add a numbering line in its definition (this will automate line numbering).
Apply "Code_numberline" to the first column, and "Code" to the 3 column.
Add a fill in the middle column.
Save that table style and enjoy!

The best presentation for code in documents is in a fixed-width font (as it should appear in an IDE), with either a faint, shaded background or a light border to distinguish the block from other text.

If its Java source code copy it to Visual Studio and then copy it back to Word.
