For one of the side products, I wish to manipulate line numbers that are shown on the editor in eclipse. Basically for few lines, I wish to show it in below order:
1
2
3
3_1
3_2
3_3
4
and so..
Which class handles the line numbers. I tried looking at source and found MarkerField and but it is not very helpful. Is this even possible?

Go to Windows → Preferences → General → Text Editors → Show numberlines. Click OK, then Apply changes. Then it will show the line count automatically. Save this answer.
Ctrl-L prompts you to go to a line number. Ctrl-Shift-L (in Eclipse 3.1) shows you a cheat sheet of keyboard shortcuts.
In Eclipse IDE, select “Windows” > “Preference” > “General” > “Editors” > “Text Editors” , check on the “Show line numbers” option.
org.eclipse.jface.text.source.LineNumberRulerColumn is responsible to display line numbers. org.eclipse.jface.text.source.LineNumberChangeRulerColumn extends above for other minor adjustments.
This is and initialized and used by org.eclipse.ui.texteditor.AbstractDecoratedTextEditor. TextEditor extends above and it is the default one used by eclipse. So to manipulate, there is a lot to be done respectively in each class.
I hope someone can provide a more comprehensive answer
