I have implemented this feature in another CVS visualizer written in Pike: Code Librarian. Here is the algorithm for reading diffs produced by cvs rdiff, picking out from-line in revision r1 and to-line in revision r2 for every diff chunk between the two revisions. It is used for generating the line number links in, for instance, http://pike.ida.liu.se/development/cvs/diff-popup.xml?module=Pike&file=7.7/src/post_modules/GTK2/source/gtkcomboboxentry.pre&from=1.1&to=1.2 The output produced is a mapping with an array of chunk mappings listing their from/to line numbers and number of diff lines in either revision, and an array of diff lines, one for each line in the produced unidiff. Each diff line mapping also lists the corresponding lines in the from/to revisions.

That sounds like a nice feature. Actually something that I'm working around very often at the moment by having several views of the same file open at the same time. Does anyone have an idea how this could be implemented cleanly UI-wise? Btw. cvs.php.net currently runs CVS HEAD code from a few weeks ago.

In editing, I forgot to mention, my experience with Chora comes from viewing cvs.php.net. I don't know which version of Chora is being run there, but I'm sure Chuck does.

When looking at a file in annotate mode, it indicates the version each line was modified in. That version number (let's say x) is hyperlinked to the view mode of that version. But, what I'm usually looking for is what was on the given line _before_ it was changed. So, it would be very helpful to have a link to that line in version x-1 of the file, with the display of x-1 being in annotate mode too, so I can jump back another revision again if necessary.
