Opening a Diff

code -d <file1> <file2>

Git Diffs in VS Code

Simple Approach (no config needed)

# Compare with previous commit
git show HEAD~1:path/to/file > /tmp/old && code -d /tmp/old path/to/file

# Compare with specific commit
git show abc123:path/to/file > /tmp/old && code -d /tmp/old path/to/file

# Compare staged version with working tree
git show :path/to/file > /tmp/staged && code -d /tmp/staged path/to/file

Gotchas

• File must exist and have changes between the compared revisions
• Use

  git log --oneline -5 -- path/to/file

  to verify file has history before diffing

When to Use

• Showing the user what changed in a file
• Comparing two versions of code
• Reviewing git changes visually
