Generated patch is empty

[Shenmue]

I am new to patching so I've followed the developer tutorial : https://docs.freemmorpgmaker.com/dev/sharing/creating.html, but when I use the command below, the generated file is empty.

git format-patch development --stdout > patchName.patch

I've created a branch from "development" and I am using the comand from that new branch.

I've pushed and synchronized everything, I did not merge the new branch into the original development one.

 

Spoiler

Actually I did merge the new branch into the original development one , but I took the most recent version of intersect on the official GitHub and replaced the code and file of the actual branch so it is just like the original.

 

If I replace "development" by "master" in the command, the file is no more empty, but has 300 kb of unrelated text to the modifications I've made.

If I execute the command from the development original branch and I replace "development" with the new branch name, a smaller file ~50 kb is generated with more related contents, but when I try to check if the patch is valid with the command below, I get few errors.

git apply --check patchName.patch

Can someone help me with this please?

You need to checkout or be on the branch with the edits you want in the patch. 

 

Then you run the git format patch command and reference the original branch to compare to.

I see, thanks JC
