Introduction
Handling conflicts is difficult!
One useful way to handle them, is to use git’s diff3 conflict style:
git config --global merge.conflictstyle diff3
And then when you get a conflict, it looks like:
Unconflicted stuff
<<<<<<< HEAD
Version A changes
|||||||
Base version
======= Version B
Version B changes
>>>>>>>
More unconflicted stuff here
Then you are supposed to manually merge the useful changes in the top and bottom parts, relative to the base version.
A useful way to do this is to figure out which of the changes (Version A or Version B) is a simpler change.
Perhaps one of the versions just added a small comment above the code section:
Unconflicted stuff
<<<<<<< HEAD
Added a comment here
BASE
|||||||
BASE
======= Version B
BASE and complex changes here
>>>>>>>
More unconflicted stuff here
One easy thing to do, mechanically, is to apply the simple change to the other 2 versions. Thus, it becomes:
Unconflicted stuff
<<<<<<< HEAD
Added a comment here
BASE
|||||||
Added a comment here
BASE
======= Version B
Added a comment here
BASE and complex changes here
>>>>>>>
More unconflicted stuff here
Now, you can run this little utility: git-mediate, which will see the conflict has become trivial (only one side changed anything) and select that side appropriately.
When all conflicts have been resolved in a file, “git add” will be used on it automatically.
Simpler case
You might just resolve the conflicts manually and remove the merge markers from all of the conflicts.
In such a case, just run git-mediate, and it will “git add” the file for you.
Installation
Recommended: Using haskell-stack
- Install haskell stack
- Run:
stack install git-mediate
Alternative install: from sources
Clone it:
git clone https://github.com/Peaker/git-mediate
cd git-mediate
Option #1: Build & install using stack: stack install
(make sure you installed haskell stack)
Option #2: Build & install using cabal: cabal install
(make sure ~/.cabal/bin
is in your $PATH
)
Use
Call the git-mediate from a git repository with conflicts.
Additional features
Open editor
You can use the -e
flag to invoke your $EDITOR
on every conflicted file that could not be automatically resolved.
Show conflict diffs
Sometimes, the conflict is just a giant block of incomprehensible text next to another giant block of incomprehensible text.
You can use the -d
flag to show the conflict in diff-from-base form. Then, you can manually apply the changes you see in both the base and wherever needed, and use git-mediate again to make sure you’ve updated everything appropriately.
