Text Diff Comparison Tool

Understanding Text Diff

Text diff (difference) tools compare two pieces of text and highlight what has changed between them. This is essential for tracking modifications, reviewing code changes, and understanding document revisions.

Color Coding

Green Background

Lines that were added in the modified version

Red Background

Lines that were deleted from the original

Yellow Background

Lines that were modified (changed)

View Modes

  • Side by Side: Shows original and modified text in parallel columns for easy comparison
  • Unified View: Shows changes in a single column with - for deletions and + for additions
  • Both modes highlight the same differences, just presented differently

Common Applications

  • Git/Version Control: Review commits and pull requests
  • Code Review: Check changes before merging
  • Document Editing: Track revisions in contracts
  • Testing: Compare expected vs actual outputs
  • Configuration: Compare config files across environments

Diff Algorithms

This tool uses a simple line-by-line comparison algorithm. Professional tools use more sophisticated algorithms like:

  • Myers Diff: Used by Git, finds minimal edit distance
  • Patience Diff: Better for code with unique lines
  • Word-level Diff: Shows changes within lines
