Allow diff of the current edit to be viewed when editing a wiki page

[pickscrape@…]

Rationale:

• To allow you to review what you have written without having to remember it all
• So you can check that your edit is tidy
• To check that you didn't accidentally delete things you didn't mean to etc

Two ways I can think of doing this:

• Include the diff by default on the preview page. So the user gets to see the finished page and the diff at the same time.
• Add an additional button next to the Preview/Submit changes/Cancel buttons which leads to a diff display

Great idea, I only wish I had it myself… wait, I actually had it myself a few months ago ;-)

Please try out Trac 0.11, you'll find an additional "Review" button.

How right you are. :) I'd only skimmed the shorter list of 0.11 changes and not seen it there, but I do see it in the more detailed change documentation now that I look.

Very much looking forward to 0.11's release!
