How to get list of files that were affected since a specific revision in Mercurial

How do I get a list of all files affected in a changeset since rev 3456?

Note: I tried hg log --rev 3456:tip --template "{files}"\n but there are several problems

1. If a changeset affects multiple files, they all appear on the same line.
2. This also shows the same file multiple times if a file was involv开发者_运维问答ed in many changsets.

hg stat --rev 3456

hg stat --rev 3456:tip to exclude uncommitted changes

There's a previous question that covers the same issue, with the added restriction that the search be restricted to files belonging to 'myself.' You can simply remove the '--user' and it should do what you need.

create a file named "mystyle"

changeset = "{files}"
file="{file}\n"

Then hg log --style mystyle --rev 3456:tip | sort | unique
