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 offsets and counts.

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

The types of changes that are currently handled are:

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

+o Adding new line insertions or deletions.

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

+o Adding a single hunk (@@-prefixed section).

+o 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.
