Visible Tabs?

Submitted by rovf on Tuesday, 23 March, 2010 - 17:29

I have set my global options like this:

Tab Width: 4
Soft Tabs: checked

When I press the Tab character, the text is intended to the next multiple of 4 characters, and the intending is done by inserting spaces. This is OK.

When I however open a file which already containins tabs, these settings cause jedit to display the text alsoe tabulated to a multiple of 4, but there is no visual clue that we have a tab character (it looks not different from spaces).

What I would like, however, is the following behaviour:

- If the text contains "hard tabs", they should be displayed either using some special (rarely used) character - as most text editors do - or by using a different background colour - which I would prefer.

- In addition, I would like to set up a different tab width for hard tabs (for instance, 8 characters).

Is this possible with jEdit?

Or use syntax highlighting

You can also modify the syntax highlighting rules to highlight tabs. In particular, this gives the ability to change the background color of tabs, which the WhiteSpace plugin does not do.

For instance, add the line below to the c.xml file (somewhere in your jedit application or settings directory), inside its <RULES> tag:

<SEQ TYPE="LITERAL4">	</SEQ>

Then adjust the background of Literal4 in jEdit's syntax highlighting preferences. The 	 is a tab character (ASCII 9).

Whitespace Plugin

You need the Whitespace Plugin and have to enable "Show Tabs".

That's the way, most of the WhiteSpace plugin's features are applied:
- You can toggle them immediately for the active buffer via plugin menu
- You can set a default for newly opened buffers via plugin options pane

So, changing an option in plugin options pane has no effect for already opened buffers! You have to re-load the buffer after checking this option. Or You can toggle an option by invoking the corresponding action via menu "Plugins -> WhiteSpace.

Regarding Tab width:
Since this is a per buffer setting (Utilities -> Buffer Options), You can have a different tab width in every buffer. But in one buffer You can have only one witdth - same for hard and soft.

Whitespace

just tried this, but I am unable to see hard tabs either. Installed Whitespace and set it to show tabs in a shade of blue not used in my color scheme. Nothing. I'm running 4.3.1 under Windows 7

1. What means "Nothing"?
2. Did You pay attention to my handling notes (resp. the plugin help)?
3. Try also to show spaces.

Whitespace plugin works well. If You enable to show all kind of whitespace You must see something!
