I need to view the tabs and spaces and CRLF in python source code in eclipse the same way we could see them in notepad++, Now I have to edit in notepad++ and run in eclipse. Not a neat way but eclipse does regular update of the changes of same file in other editor.
This should be cover with the "Show invisible" option
From Eclipse3.3:
It is now possible to see the invisible whitespace characters in textual editors:
This feature can either be controlled via "General > Editors > Text Editors > Show whitespace characters" preference, or via the tool bar button when the Editor Presentation action set is enabled.
I did not tried it with PyDev, but its editor should be a "textual editor", and the option should work.
when I press TAB it creates spaces instead of >> for tabs
Check the option "General > Editors > Text Editors > Insert spaces for tabs":
if unchecked, it will display tabs, not space.

Is there a way to configure Eclipse to not use white spaces, BUT to still only indent 2,3,? spaces instead of the standard 4? I don't want to move to white spaces instead of tabbing, because I believe this is a personal choice for the person working on the project.
The closest answer I've seen is https://stackoverflow.com/a/2477132/5525659
It works, but I'm wondering if there is a better/easier way if people are sharing files different ways?
Any insights are appreciated.
You can change the displayed tab width in Window > Preferences: General > Editors > Text Editors.
In Java, the displayed tab width can be set in the formatter profile: Window > Preferences: Java > Code Style > Formatter, in the profile dialog, in the Indentation tab, in the field Tab size.
Other editors might use the text editors preferences or have their own preferences.
I am using Eclipse Luna. I have installed the Perl EPIC plugin. I want to indent 4 spaces instead of TAB.
I have checked Window -> Preferences -> General -> Editors -> Text Editors -> Insert spaces for tabs, but still when there is need to auto indent a new line, Eclipse still indents with TAB instead of spaces.
How do I change it so EPIC will use spaces instead of tabs for indentation in Perl files?
Late answer but I ran into the same issue, found this post, and subsequently how to change the formatting settings for Perl EPIC in Eclipse.
From the main IDE workspace, click the Window menu and then choose Preferences.
Scroll down to Perl EPIC and expand it in the tree.
Click the Editor entry.
In the right panel under the Appearance tab, you can change your preferences for Insert tabs/spaces on indent and whether or not to use spaces instead of tabs.
I recently moved from geany to Aptana as I'm working on some bigger projects and felt I would benefit from a full IDE.
One feature I'm really missing is the little grey line every four spaces to help me maintain indentation consistency. Does anything like this exist for Aptana/Eclipse?
get the PDT tools Indent Guide plugin
Under
Preferences -> General -> Editor -> Texteditor you can activate "Show whitespace characters". If you click on "whitespace characters", you can define, which character should be displayed. Here you can active "Tabs". It's not as good as the lines from Notepad++, but better than nothing.
You can set a print margin indicator (vertical line) in Preferences > General > Editors > Text Editors - but this would only be a single line. You could use tabs instead of spaces - there are options to insert spaces when you use the Tab key. In this same menu, you can choose to show whitespace characters, which will help keep your spacing in order. I don't know of any grid options.
I'm trying to switch from Komodo to Eclipse.
I can't figure out how to keep line-break characters from being shown in eclipse - looks like they are shown along with tabs and other whitespace characters.
Is there a way to show tabs and other whitespace characters but not line-break characters?
If you have Eclipse 3.7 you can disable them.
Preferences > General > Editors > Text Editors -- Look for 'Show whitespace characters' and click on the link 'whitespace characters'.
Or you can directly click on the shortcut:
In the Luna version, this configurability is now called "configure visibility" under "Show Withespace characters"
In your Eclipse, go to:
Window --> Preferences --> General --> Editors --> Text Editors
Click the highlighted link (configure visibility) in the check-box SHOW WHITESPACE CHARACTERS and select the check box as per your requirement.
Somehow I've turned on hidden characters in Eclipse. It's not the "whitespace" characters in the general editor preferences. When turned on, it adds another layer of hidden characters over the existing ones.
Then I have things like
\r\n
Does anyone know what these are and how to remove them?
It is under Preferences > General > Editors > Text Editors. There is a checkbox labeled "Show whitespace characters". If you uncheck this the editor switches back to normal.
If you click on the link (whitespace characters) (<= v3.6) or (configure visibility) (>= v3.7) in this line you will get a popup window, in which you can define which characters eclipse is supposed to consider as whitespace characters.
In this popup window you also get the option to define the transparency in which each whitespace character is displayed in the editor, which you can use to (indirectly) change their foreground colour. I'm just mentioning it here, because it took me about half an hour to find this setting! ;-)
There is a toggle button 'Show Whitespace Chars' on the Eclipse toolbar
A great tip about using 'quick access' from eclipse forum:
CTRL+3 swc
Allows to turn them on and off
The right shortcut is Ctrl + N
UPDATE From Eclipse 3.7 version, something is changed... Now you have to go to:
Window > Preferences > General > Editors > Text Editors
CTRL + . does the job.
For Aptana Users
To toggle hidden characters in Aptana on and off, use the following keyboard shortcut:
Ctrl+Alt+W
I am using Eclipse Oxygen and can see this option to toggle whitespace characters:
It is actually in two places...
Sandkastenliga points out the obvious one, but you can also show white space with a shortcut key combination. The key combination is separate from the text editor preferences and will superimpose additional characters when active (it uses \r and \n for carriage return an line feed respectively instead of the symbols used by the text editor preference.)
Go to preferences > general > keys and look for the binding for the 'Show Whitespace' command.
I have the text editor preference turned on, so I removed the binding for this command altogether (it was set to Ctrl+. in my profile) to prevent accidental activation as it doesn't affect the other preference.
Go to Window > Preferences > General > Editors > Text Editors
Uncheck the "Show whitespace characters" option on the right side of the page, then click "Apply" at the bottom of the page.
Since this is not a standard setting, it could be the result of one of your extra plugin.
Did you try starting your eclipse with the -clean parameter?
Do you reproduce the issue with a fresh Eclipse installation?
Go to Preferences > General > Editors > Text Editors and restore defaults.
I have done this several times by accidentally hitting some keystrokes.
If you go to Windows/Preferences/General/Keys you will see all the keyboard shortcuts you have.
Mine is set to Control + .
I had to place my cursor inside the document and do it a couple of times to make it work because there is also a keyboard shortcut for Control +
Hope that helps.
You can add "Show Whitespace Characters" button in toolbar by customizing your perspective.
It also contains buttons to toggle word wrap, and toggle selection mode.
Go to Window > Perspective > Customize Perspective > Action Set Availability, then select "Editor Presentation" action set:
This works in Eclipse Neon.
You can also add a key binding for this action.
Go to Preferences > General > Keys > "Show Whitespace Characters"
Sorry this is a bit vague but it's a while since i used Eclipse and i do not have it installed. I think this is it ..... in one of the menus you will find the Eclipse settings, there are two set's of settings, current project and overall Eclipse, you mat need to check them both. In there are various menus in tree form that allow you control the actions and look and feel. But some of them are nested so there is an overall control but some packages have their own options in a sub menu set. The menu's will expand when you click them and i'm afraid you need to walk through them all.
Eclipse > Preference > General > Editors > Text Editors > Show WhiteSpace characters.
