When i type a new word in eclipse pydev, it gets yellowishly higlited. Which makes it very difficult to read. How to remove this highlighting??
You can configure that color in the preferences:
General > Editors > Text Editors > Annotations > Occurrences (PyDev)
Whenever I click on the Code tab to see the Java code of Talend job, I never see see the line numbers. Is there any settings to enable line numbers?
You can enable line numbers from Preferences
You will see a parameter for Show line numbers if you follow this breadcrumb -
Window > Preferences > General > Editors > Text Editors
In some editors, overlong lines are marked. e.g. by a vertical bar after column 80, or by shading everything after column 80.
Can I do this in eclipse?
eclipse: Window > Preferences > General > Editors > Text Editors: show print margin [checkbox] And: print margin column [...]
You could use the checkstyle plugin Download site here
How can I show line numbers by default in Eclipse?
Window → Preferences → General → Editors → Text Editors → Show line numbers.
Edit: I wrote this long ago but as #ArtOfWarfar and #voidstate mentioned you can now simply:
Right click the gutter and select "Show Line Numbers":
If this doesn't work it may be overridden by your current settings. You can right-click in the bar to the left of the code where line numbers would normally appear and turn them on with the context menu.
Update November 2015:
In Eclipse Mars 4.5.1, line numbers are (annoyingly) turned off by default again. Follow the below instructions to enable it.
Update December 2013:
Lars Vogel just published on his blog:
Line numbers are default in Eclipse SDK Luna (4.4) as of today
(December 10, 2013)
We conducted a user survey if users want to have line numbers activated in text editors in the Eclipse IDE by default.
The response was very clear:
YES : 80.07% (1852 responses)
NO : 19.93% (461 responses)
Total : 2313
Skipped: 15
With Bug 421313, Review - Line number should be activated by default, we enabled it for the Eclipse SDK build, I assume other Eclipse packages will follow.
Update August 2014
Line number default length is now 120 (instead of 80) for Eclipse Mars 4.5M1.
See "How to customize Eclipse's text editor code formating".
Original answer (March 2009)
To really have it by default, you can write a script which ensure, before launching eclipse, that:
[workspace]\.metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.ui.editors.prefs does contain:
lineNumberRuler=true
(with [workspace] being the root directory of your eclipse workspace)
Then eclipse will be opened with "line numbers shown 'by default' "
Otherwise, you can also type 'CTRL+1' and then "line", which will give you access to the command "Show line numbers"
(that will switch to option "show line numbers" in the text editors part of the option.
Or you can just type "numb" in Windows Preferences to access to the Text Editor part:
Picture from "How to display line numbers in Eclipse" of blog "Mkyong.com"
As simple as that.
Ctrl+F10, then N, to Show or hide line numbers.
Reference : http://www.shortcutworld.com/en/win/Eclipse.html
Slight variation on Mac OSX:
Eclipse → Preferences → General → Editors → Text Editors → Show line numbers
Windows → Preferences → General → Text Editors → Show numberlines
in this file
[workspace].metadata.plugins\org.eclipse.core.runtime.settings\org.eclipse.ui.editors.prefs
make sure the parameter
lineNumberColor=0,0,0
is NOT 255,255, 255, which is white
Go to Windows → Preferences → General → Text Editors → Show numberlines. Click OK, then Apply changes. Then it will show the line count automatically.
one of the easy way is using shortcuts like : Ctrl+F10, then press n "it show line number and hide line numbers.
The top answer is good but you can also bind it to a key ( shorcut ) to toggle it..
Window > Preferences > Keys then enter "Line Numbers" in filter and bind it to a key.
I use CTRL + S + L.
Open Eclipse
goto -> Windows -> Preferences -> Editor -> Text Editors -> Show Line No
Tick the Show Line No checkbox
click on window tab and click on preferences
do this and check show line number
the eclipse changes the perferences's position
to eclipse -> perferences
On a Mac do this:
cmd + , or ADT -> Preferences
Expand General -> Editors ->Text Editors
Check box: Show line numbers
Eclipse has a search feature in the top left box of the Preferences.
Type in 'line numbers' in that search box, and presto...
In case you're tired of googling each time you forget...
this will be the appropriate solution for asked question:
String lineNumbers =
AbstractDecoratedTextEditorPreferenceConstants.EDITOR_LINE_NUMBER_RULER;
EditorsUI.getPreferenceStore().setValue(lineNumbers, true);
Is there a way to hide the text limit line in netbeans 6.5?
In NetBeans 6.9, setting Right Margin to 0 effectively hides the text limit line.
Set the value in Preferences > Editor > Formatting > All Languages > Right Margin.
(Mac OS X 10.6.4, NetBeans 6.9)
line is not moving to 200 column, but you can hide it setting its color to same as the background
You can set it to 0. So It will not be visible.
Are you talking about the line running thru the right side, by default at the 80 column point? That is Options -> Editor -> Indentation -> Right margin. I have it set at 200 columns which pushes it off the right side of the screen.
Hi~ I found out how to hide "Text limit line" :)
Tools -> Options -> Export(Popup Win) -> Browse.. (Select target "ccc.zip" file)
Select Options for Export : Check at "Editor" -> OK
Edit xml file "\Editors\Preferences\org-netbeans-modules-editor-settings-CustomPreferences.xml" in "ccc.zip" file.
<entry javaType="java.lang.Boolean" name="text-limit-line-visible" xml:space="preserve">
<value><![CDATA[false]]></value></entry>
Tools -> Options -> Import "ccc.zip" file
Done
As for now (October '18) in NetBeans 8.2 + 9 you can hide the text limit line or actually change its color by going to Options -> Fonts & Colors -> Highlighting -> Text Limit Line -> Foreground
Remember to go to tools, options, fonts & colors, highlighting tab, text limit line selected before exporting ccp.zip....
There is an easy way to disable the warning generated by NetBeans for number of lines.
Goto Tools > Options > Editor > Hints
Find the checkbox Too Many Lines > un-check the checkbox
and click Apply.
Enjoy :)
Have you tried to see if your project properties have formatting that overwrites the global properties?
