Question

For merging I use this to “keep mine”

git merge -X ours foo

and this for “keep theirs”

git merge -X theirs foo

However on my latest merge it looks best to keep both sides. Does Git have a “strategy” for this, to avoid manually editing the file?

Answer 1

There is no ‘merge strategy’ for resolving these conflicts.

However, if you truly want a conflict like:

<<<< ours
Foo
=========
Bar 
>>>> theirs

to resolve to

Foo
Bar

then you can configure the ‘merge driver’. From the gitattributes man page:

union

Run 3-way file level merge for text files, but take lines from
both versions, instead of leaving conflict markers. This tends to
leave the added lines in the resulting file in random order and the
user should verify the result. Do not use this if you do not
understand the implications.

Add a line to .gitattributes to use this:

*.whatever merge=union
