I've just updated NetBeans to 8.0 and I've experienced that the editor displays a strange/weird reverse P character at the end of each line.
How do I remove it?
Image:
Please go to 'View' and uncheck the Show Non-Printable objects. That clears off your problem
This is a [CR].
You should be able to remove it with a search and replace. Search for \r\n and replace with \n. You may need to switch on regexp.
If you only want to 'hide' the paragraph sign but show other whitespace I would advice you to install the editor-whitespace plugin (http://plugins.netbeans.org/plugin/52662/editor-whitespace).
This approach is very different from How to remove strange reverse P character at end of line is this solution will hide all Non-Printable objects which is not what is asked.

I searched everywhere for this, the problem is that the search criteria is very similar to other questions.
The issue I have is that file (script actually) is embedded in another file. So when I open the parent file I can see the script as massive string with several \n and \r\n codes. I need a way to convert these codes to what they should be so that it formats the code correctly then I can read said code and work on it.
Quick snippet:
\n\n\n\n\nlocal scriptingFunctions\n\n\n\n\nlocal measuringCircles = {}\r\nlocal isCurrentlyCheckingCoherency
Should covert to:
local scriptingFunctions
local measuringCircles = {}
local isCurrentlyCheckingCoherency
perform a Regex Find-Replace
Find: (\\r)?\\n
Replace: \n
If you don't need to reconvert from newlines to \n after you're done working on the code, you can accomplish the trick by simply pressing ctrl-f and substituting every occurrence of \n with a new line (you can type enter in the replace box by pressing ctrl-enter or shift-enter).
See an example ctrl-f to do this:
If after you're done working on the code you need to reconvert to \n, you can add an invisible char to the replace string (typing it like ctrl-enter invisibleChar), and after you're done you can re-replace it with \n.
There's plenty of invisible chars, but I'd personally suggest [U+200b] (you can copy it from here); another good one is [U+2800] (⠀), as it renders as a normal whitespace, and thus is noticeable.
A thing to notice is that recent versions of vscode will show a highlight around invisible chars, but you can easily disable it by clicking on Adjust settings and then selecting Exclude from being highlighted.
If you need to reenable highlighting in the future, you'll have to look for "editor.unicodeHighlight.allowedCharacters" in the settings.
I cannot figure out how to do this for the life of me apart from doing a find-replace on 4 spaces and converting to tabs (Version 0.10.2). I can't think of an editor/IDE that doesn't have a specific feature to do this. Does VSCode?
Since fix of: https://github.com/Microsoft/vscode/issues/1228 the editor supports it out of the box. Simply go for:
F1,
indentationToSpaces or indentationToTabs (depending on your need)
Enter.
Another way to do it is click the current indentation (Tab/Spaces:n) on the footer which will open your indentation options where you can select what you want to do.
If you are trying to convert non-leading tabs to spaces (or vice versa) you can use a regex search and replace.
Press CTRL + H
Click the .* button to search using regular expressions.
To search for tabs enter [\t] in Find box.
Enter spaces in Replace box and perform your replace.
Search box in regex mode:
To round out these answers, I will add my take for converting each tab to n spaces.
Highlight a tab character
Use CTRL + F2 select all occurrences
Press SPACE n times
This is the easiest way to do this (going beyond only converting leading tabs).
Note that this does not convert consecutive tabs to k spaces. It converts each tab. For consecutive tabs please see my comment on jrupe's answer. You will need VS Code find and replace with regular expressions to accomplish that.
Select Replace: CTRL-H
Enter Horizontal Tab in Find box: hold ATL and type 009 on the keypad.
Enter a space(or more spaces) into the Replace box: press space bar
Press Enter to begin replacing Tabs with Space(s).
Press F1 and then type into textbox convert indentation to spaces or whatever you want ones
On Visual Studio, Ctrl+K+F did the trick for me.
Fast forward to 2020/2021, there are some extensions that will give us that conversion. I have just needed that functionality (hence I found this article), and searching for extensions I found:
geocode.spacecadet - providing both TAB->SPC and SPC->TAB, but not updated since 2017, with 1.3k installs, 3.5 review
takumii.tabspace - TAB->SPC, from 2020, 1.5k installs, no reviews
pygc.spacetab - SPC->TAB, from... wait, literally yesterday! (or today depending on your TZ), 2 installs, no reviews
How can I remove lines that only contain spaces when using Eclipse Find/Replace prompt. I checked the "Regular Expression" check box, and tried the following, neither of which worked.
^[:space:]*$
and
^\s*$
Find: ^\s*\n
Replace with: (empty)
sry this might be an different answer but you can set the number of blank lines you wish to have after fields, methods and blocks in the formatting dialog of the eclipse preferences. then you can hit ctrl-shift-f to automatically format your code depending on your custom definitions.
have fun!
I was suprised that for XML files edited with Eclipse there is a good solution:
Select the checkbox value named 'Clear all blank lines' in Formatting panel
Window->Preferences->XML->XML Files-> Editor
Save and use the "Ctrl+Shift+F' shortcut
The blank lines will dissappear!
for the find/replace operation, "\n\r\s" regex will work on windows, for unix based system, "\n\s" can be used
as already suggested, you can format your code by Ctl+Shift+F
for manual work, locate a blank line and press Ctl+D (Cmd+D on Mac) <- gives u satisfaction of killing the line with your own bare hands :)
cheer!
This one worked for me for years:
Replace this: [\t ]+$
With nothing
Hope this helps!
Many thanks to lamamac.
In genereal, when you want to do search replace with regular expressions in eclipse the $ sign doesn't work as it should.
Use '\s*\n' instead of '$'
As already suggested, regular expression and replacement is the solution, but such response would have been saving some minutes to me:
click on ctrl+f
use this replacement:
I understand how to get Eclipse to insert spaces in place of tabs, but then I'd rather not have to arrow through 12 spaces to reach an indented block.
Bonus points if there's a way to hide the spaces from the 'show whitespace characters'. I like to see whitespace characters for tabs and carriage returns, but the display gets too cluttered when spaces are also displayed.
Try CTRL+[right,left] arrow key. Certainly one of my most-used combos.
As it turns out, this appears to not be possible in Eclipse.
With the next Eclipse 20199.12/4.14, that might actually be possible! (albeit ten years later)
See "Backspace/delete can treat spaces as tabs"
If you use the Insert spaces for tabs option, now you can also change the backspace and delete keys behavior to remove multiple spaces at once, as if they were a tab.
The new setting is called Remove multiple spaces on backspace/delete and is found on the General > Editors > Text Editors preference page.
In some editors there exist plugins implementing a feature called "hungry backspace" or "hungry delete".
If this mode is active in a text editor then one hit to the backspace key will automatically delete all whitespace chars backwards from the current cursor position up to the first non-whitespace character.
For example, this feature exists for Emacs and IntelliJ IDEA.
Does anyone know if it is also available in Eclipse?
Alt-Del is probably as close as you're going to get without writing a plugin yourself. Others have asked for this feature (coming from intelliJ) but so far it doesn't exist, or it's not published.

CTRL-backspace is pretty close too: delete previous word:
function(); (4 spaces)
+ CTRL-BACKSPACE gives:
function
Other than that, AnyEdit plugin can convert trailing spaces into tabs (but also into "", effectively removing them)
Ctrl+Shift+Left, Backspace always works for me. works in notepad, web browsers, everywhere.
Stick to the standards :)
In SciTE, and Eclipse (3.4), Ctrl+Shift+Del with the caret after the last visible character will delete these spaces. Ie. it deletes from caret to end of line.
Actually, in SciTE I don't need to do that, since I have set it up to automatically remove these trailing spaces when saving.
Note: In Preferences > General > Keys, there is a Remove Trailing Whitespace binding (without key assignment by default) which seems to apply to File.
From eclipse Windows menu/Preferences
Search for Keys and filter to "Delete Previous Word"and Bind it to the Ctrl+Backspace
