Git: Use VS Code as merge editor
Problem
1.0.0 introduced the ability to use VS Code as a git difftool. The relevant global `.gitconfig` lines are as follows: [code block] How can I use VS Code as a git mergetool? The relevant arguments it needs to accept, I believe, are `$LOCAL`, `$REMOTE`, `$BASE`, and `$MERGED`.

Configure VS Code as Git Mergetool
The inability to use VS Code as a merge tool in Git is due to the absence of the necessary configuration in the global `.gitconfig` file. While VS Code can be set as a difftool, it requires specific settings to function as a mergetool, which involves defining how it should handle merge conflicts using the appropriate arguments.

- 1
Open Global Git Configuration
Open your terminal or command prompt and access the global Git configuration file to add the necessary settings for VS Code as a mergetool.
bashgit config --global -e - 2
Add VS Code Mergetool Configuration
In the opened `.gitconfig` file, add the following configuration to set VS Code as the mergetool. This configuration specifies how VS Code should be invoked during a merge conflict.
ini[merge] tool = code [mergetool "code"] cmd = "code --wait $MERGED" keepBackup = false - 3
Set Default Mergetool
Ensure that Git uses VS Code as the default mergetool by adding the following line to your `.gitconfig` file. This will make VS Code the go-to tool for resolving merge conflicts.
bashgit config --global merge.tool code - 4
Test the Mergetool Configuration
Create a test repository and intentionally create a merge conflict to verify that VS Code launches correctly as the mergetool. Resolve the conflict and ensure that changes are saved properly.
bashgit merge <branch-with-conflict> - 5
Confirm Configuration
Check the configuration by running the following command to ensure that the settings for the mergetool are correctly applied.
bashgit config --global --get merge.tool
Validation
To confirm the fix worked, perform a merge that results in a conflict. When prompted to resolve the conflict, VS Code should open automatically. After resolving the conflict, ensure that the merged file reflects the changes made in VS Code.
