Just like python, I love using git. It’s versatile and does simplify a lot of developmental tasks.
With a distributed version control system like Git, we can actually send a path for someone to review without the need to have the centralized git repository using the git format-patch feature.
This is useful when the remote git repository is down or behind or behind an artificial throttling IT system.
Here are few ways to create patches
Creating patches from commits
let’s say you are in the “bug_fix“ branch and you want to have all the patches since master.
git format-patch master
This will create multiple patches per commit. We can create a single patch for multiple commits by using the –stdout option and directing the output to a file:
git format-patch master --stdout > mypatch.patch
One can also create a patch from git diff
git diff > something.patch
or from cache
git diff --cached > something.patch
How to use the patch?
Once you have received a patch how do you use it?
When you receive a patch file from someone, you can easily apply the patch using the git am command or git apply command.
git apply mypatch.patch
This command applies the patch but does not create a commit.
git am mypathc.patch
This command applies the patch and does create a commit with the original command
Hope this helps. It really helps me these days.
