Diffs provided within ticket comments should have a download-link

[ilias@…]

I would be nice to have an (optional) download-link of diffs which are displayed within tickets, see #4158 for an example.

[Tim Hatch <trac@…>]

I'd considered something similar but decided even more useful is to provide an mbox-export for a given ticket — that would contain the text of the diff in a form you could use. This might be a candidate for a plugin?

no idea what this "mbox" is (any pointer?)

I just realized that it would be helpful to be able to save the diff. For other text, a "copy" operation based on a simple "click" may be of benefit.

mbox format is basically like ​RFC:822, email, but with an additional specially-formatted line before the headers.

It would include the source of the ticket changes, so you'd be able to see it monospaced in an editor of your choice. As a side note, the date of the original posting is not available anywhere in this screen (just the prettyprinted date)!

A sample for the replies in this ticket (with a fictional diff block at the end, for sake of illustration) would be:

I've understood, but this would be out of the scope of this ticket.

You should possibly open one subjecting the ticket-notifications of trac (e.g. changing format to "mbox" and allowing manual "send" operation).

I was sure there was already a ticket about this, but can't find it… so maybe I was wrong. The basic problem being that the pretty-printed diff doesn't allow you to copy-paste/save the diff and apply it.

Anyway, I've got some javascript code that lets you switch between tabular and unified view of a diff, both for patches embedded in wiki text, as attachments, and the changeset view. It's pretty nice IMHO, so I'll check it in.

[Christopher Lenz]

Checked in in [4282]. As I think it addresses the intent of this ticket, I'm closing this.
