NAME

       rediff, editdiff - fix offsets and counts of a hand-edited diff


SYNOPSIS

       rediff ORIGINAL EDITED

       rediff EDITED

       rediff {--help | --version}

       editdiff FILE

       editdiff {--help | --version}



DESCRIPTION

       You  can  use rediff to correct a hand-edited unified diff. Take a copy
       of the diff you want to edit, and edit it without changing any  offsets
       or  counts  (the  lines that begin ‘‘@@’’). Then run rediff, telling it
       the name of the original diff file and the name of  the  one  you  have
       edited, and it will output the edited diff file but with corrected off-
       sets and counts.


       A small script, editdiff, is provided for editing a diff file in-place.


       The types of changes that are currently handled are:


       ·  Modifying the text of any file content line (of course).

       ·  Adding new line insertions or deletions.

       ·  Adding,  changing  or  removing  context lines. Lines at the context
          horizon are dealt with by adjusting the offset and/or count.

       ·  Adding a single hunk (@@-prefixed section).

       ·  Removing multiple hunk (@@-prefixed sections).




       Alternatively, if only one argument is provided, it is taken to be  the
       edited  file  and  the  counts and offsets are adjusted as appropriate.
       Some assumptions are made when used in this  mode.  See  recountdiff(1)
       for more information.
