[Freeciv-Dev] Multi-file diff tool

[Raimar Falke <rf13@xxxxxxxxxxxxxxxxx>]

A shortcoming of cvs diff is that you can't get a diff for all files
of a given "cvs commit" command. I.e. all which have the same commit
message. You can do this with get_diff.

Usage:
 $ get_diff -r common/hash.c:1.2

This will show information about the commit which is related to the
creation of the revision 1.2 of common/hash.c. The output is:

  common/hash.h:1.2

        Extends the functionality of common/hash.c, to remove the
        previous main limitations: individual elements can now be
        deleted, and the hash table dynamically resizes as new elements
        are added.

There is another way to specify the commit: by date. Currently only
one date format is recognized: the one from cvs. So if you want to
know what has changed in the recent commit to the SDL client and what
the commit message

  This make bigger Mess that before.
  Sorry SDLClient still not work :(

really means you will have to type

 $ get_diff -d "2003/02/21 03:40:06"

and look at the diff you get.

You need at least Python 2.0. I have only tested it with Python
2.2. The initial cvs log takes some time. It doesn't support
branches. You may want to change the parameters at the top of
get_diff.
