Mercurial: diffs in a particular changeset?

Question

This is almost exactly a duplicate of Examining a single changeset in Mercurial, and without doubt a duplicate of another question I can't find on SO through Google alone.

I'm looking back through a Mercurial repo, and I want to see what exactly changed between two revisions (let's say 2580 and 2581):

hg log -v -r 2581  

gives me all the files that changed.

How can I also see the diffs of these files?

Thanks.

Answer 1

Revision 2580 isn't necessasrily the parent revision of 2581. It's easy to check if it is, of course, but easier yet is to just do:

hg log -p -r 2581 

That compares 2581 to its (first) parent revision no matter what it is, and most clearly encompasses the answer to the question "what the hell did 2581 do?"

Answer 2

Try hg diff -r 2580 -r 2581.
