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



rediff EDITED

rediff {[–help] | [–version]}

editdiff FILE

editdiff {[–help] | [–version]}


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

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
for more information.
