Get collections of diffs

Question

Hello,

I have project on github.com. All summer i made commits. Now i need to get all pathes.

I know that i can:

git log -p > project.path

But this variant write all pathes in one file. How can i make:

I have 3 files in github repository:

• test.c

• test1.c

• test2.c

How can i get 3 files with all pathes?

• test.diff

• test1.diff

• test2.diff

Thank you

Answer 1

You can use git format-patch to create a sequence of patches from your commits (one patch per commit).

Answer 2

I can't think of any real automated way of doing it, but this worked for me on a unix system.

To start you need to have the ID of the first commit in your project, lets pretend it's 123abcd (does anyone know of an automated way to get this?).

Once you have the id of the first commit you can just loop over the files that have changed since the first commit and run a diff on each one:

for file in `git diff --name-only 123abcd`; do 
    git diff 123abcd ${file} > `basename ${file}.patch`
done

What it all means:

git diff --name-only 123abcd

Will give you a list of any files that have changed since revision 123abcd

git diff 123abcd ${file} > `basename ${file}.patch`

Generates the actual diff and saves it into the name of the file without the path to it.

When you're finished your current working directory should hold all your .patch files.
