Frequently Asked Questions about text-diff

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I compare two files to see what text was changed?▼

Comparing two files identifies differences by analyzing their contents and highlighting changes. You can visualize modifications using unified diff, context diff, or side-by-side views for clear code review and version tracking.

Can I generate a patch file from text differences?▼

Generating a patch file from text differences creates a file representing the modifications between two inputs. This output is useful for applying specific codebase changes and tracking version updates.

What is the best way to view code differences side-by-side?▼

Viewing code differences side-by-side displays original and modified text simultaneously to highlight exact changes. This Skill supports side-by-side views alongside unified and context diff formats for accurate text analysis.

Does this text comparison tool work without external dependencies?▼

Text comparison operates without external dependencies, utilizing Python's difflib module internally. This ensures accurate comparison of file contents and reliable patch generation in a self-contained environment.

What diff formats are supported for code review?▼

Supported diff formats for code review include unified diff, context diff, and side-by-side views. These options provide clear visualization of changes between two files or text inputs for effective analysis.

When do I need to use a unified diff format?▼

A unified diff format is needed when you want a compact, standardized representation of changes between two files. It displays removed and added lines together, making it ideal for code reviews and patch generation.
