汞：如何获取两个不同文件的差异？

Question

I'm sorry if it's odd question. I have a mercurial repository. Is it possible to get a diff of two different files from some revision by hg ? For example, there is a revision

revision xxx
    - file1
    - file2

How I can get a diff of file1 and file2 by standard hg command or any extensions?

Thank you.

UPD I would like something like this:

hg diff -r xxx file1 file2

Than I will have all changes between two files of same revision.

Answer 1

Initially I read your question differently, but your comment made clear that you are asking about the differences between two files of the same revision . That's nothing where the VCS has any stakes in.

You simply can use (on *nix systems) the diff command:

diff FILE1 FILE2

If you need the difference of the files at particular revisions, of course you can use mercurial before that in order to get to that:

hg update -rXXX

or even to see the difference of FILE1 at revision XXX compared to FILE2 at revision YYY (but beware, it changes the working dir content; make sure to undo the revert afterwards):

hg revert -rXXX FILE1
hg revert -rYYY FILE2
diff FILE1 FILE2
