I recently had an occasion to take a rather large git-diff patch, and split
it into smaller chunks. This was so I can more easily import the patches
into guilt, then reorder, rename, shuffle, and join individual patch
snippets into logical patches (i.e., one patch per topic).
I was looking around for a tool that would allow me to split a large patch
file into individual snippets and couldn't find one. So I wrote one in
perl. It takes a patch file and creates individual small files, one for
each combination of a filename listed in the patch, and a patch snippet
(starting with an '@@' line). Each '@@' snippet gets an index number and a
new filename, prefixed with the appropriate header ("diff ...", ---, and +++
lines) so it's a valid patch file on its own.
Questions:
1. Does anyone know of such a tool, perhaps written in C for better speed?
2. If not, is there any interest in such a tool? If there's interest, I'd
be happy to cleanup my perl script and contribute it to
git/guilt/whatever.
Cheers,
Erez.
