Editor that supports renaming tabs for untitled docs?

Question

I sometimes need to copy/paste text into two windows and compare the contents for a quick hack, ie. without having to save both documents to disk, and display the two docs side-by-side vertically so I can scroll them independantly (WinMerge doesn't seem to support independent scrolling.)

Since the documents only live in RAM, text editors will display a non-descript tab/filename like "Untitled1" or "New file 1":

Does someone know of a Windows editor that supports...

• renaming tabs with more descriptive names even with documents that haven't been saved to disk,
• side-by-side, vertical tiling, and
• independant scrolling?

Answer 1

Vim will do that. The Cream version has an interface that is more consistent with other Windows programs.

First start gvim. Create two side-by-side windows by executing :vnew. Paste your documents into the two windows. To show their differences, execute :windo diffthis. The two windows scroll together by default. To make them scroll independently, execute :set noscrollbind. To name each window, click in the window to select it, then execute :f somename where somename is the name you've chosen for that document.
