Description Darin Delegal

2003-09-26 09:28:39 EDT

A couple of requested/suggested additions to the main file editor windows:

- A top ruler bar with column numbers
- The ability to configure and display more than one vertical hairline (like 
the print margin display).
- The ability to display "hidden" characters such as tabs, linefeeds, etc.
- Column based editing for insert/delete/select, etc.

I know these probably fall into the low priority category, but they would be 
very useful...

>A top ruler bar with column numbers
row:column indication is already available (see status bar). There are currently
no plans for additional support.

>The ability to display "hidden" characters such as tabs, linefeeds, etc.
see bug 22712

>column based editing for insert/delete/select, etc.
see bug 19771

So the only thing which remains is:
>The ability to configure and display more than one vertical hairline (like 
>the print margin display).

==> changed the PR summary.

Note: There should only be one report per request.

Plus one on per-project vertical lines.

Eclipse's JDT and CDT changed around Eclipse Mars time to ignore the print margin column setting in the "Text Editor" preferences. There were a couple of bugs raised as a result of this, because it meant the print margin behaviour was just weird. As a result, and partly due to a lack of acceptance that this is a poor choice (not just in my opinion, but I was probably the most vocal about it), Robert Zenz (with a little bit of help from me) has created a plugin called ArbitraryLines that will let you have vertical lines, or horizontal lines, displayed wherever you like in the edit view (pretty much). This came out of some discussions on bug 468307. You can find the plugin at:

https://marketplace.eclipse.org/content/arbitrarylines

You set up the lines you want drawn using the preference page under Text Editors, and it draws the lines based on the settings you specify! Amazing, huh?

We hope it's of use to you.
