Diff Checker Tool
Compare two text blocks or code files side by side. Highlights additions, deletions, and modifications line by line. Essential for code reviews, document comparison, and tracking changes.
How Diff Works
The tool uses the Myers diff algorithm to find the minimum set of changes between two texts. Lines are color-coded: green for additions, red for deletions, yellow for modifications.
Use Cases
- Code review: Compare before and after code changes
- Configuration: Find differences between environment configs
- Documents: Track what changed between versions
- Debugging: Compare working vs broken code
- Database: Compare SQL dumps or schema versions
View Modes
- Side by side: Old and new text in parallel columns
- Unified: Single view with additions/deletions marked inline
- Inline: Changes highlighted within the same text block
Tips
Ignore whitespace changes when comparing code logic. Use character-level diff for finding small typos. For large files, focus on changed sections rather than reviewing unchanged content.
