Line Diff Explained
Most diff tools, including this one, work line by line. Here is what that means and why it suits code and configs.
Lines as units
A line diff treats each line as the smallest unit of change. If anything on a line differs, the whole line is marked changed. This keeps comparisons readable for structured text.
When you need more granularity
For prose where you want to see which words changed within a line, a character or word diff is finer. For code, configs and logs, line diffing is usually exactly right.
Frequently asked questions
Can I use this for production work?
Yes, for inspection, formatting and quick generation. Still review the output before committing it to production code or configuration.
