How to create branch-specific files on GitHub

问题

I would like to have branch-specific files with the same name. I need to be able to merge from my development branch to master without changes made in this file.

For example:
Let's assume that I would like to have two different readme.md files. In one I would like to have content: MASTER and in another DEV. But if I try to do it, while creating pull-request GitHub will try to merge this file, which is exactly my problem. I don't want GitHub to merge this file each time I make changes.

What would be the best way to solve this problem?

回答1:

Let's say project is a name of the branch to be merged, and README.md is a name of the file that keep branch specific information.

I would suggest the following steps:

Merge project branch, but make sure changes are not committed, and not fast-forwarded
```
$ git merge --no-commit --no-ff project
```
Unstage README.md file and checkout its current branch version
```
$ git checkout HEAD -- README.md
```
Complete merge
```
$ git commit
```

Also, it makes sense to install merge driver that will keep branch specific version of a file in case of merge conflict. In such case, you will never need to resolve conflicts in branch specific files manually.

Such merge driver is usually called ours and defined as:

$ git config --global merge.ours.driver true

Now, you can specify in .gitattributes file, when this merger should be used.

In our case, it is needed to add the following rule to .gitattributes and commit it:

README.md merge=ours
