Why this exists
---------------

[](#why-this-exists)

Content synchronization needs more than "last write wins." A Markdown file changes in Git while the same post changes in WordPress. A generated config changes through both a CLI tool and a UI. In those cases you need a common ancestor, two edited versions, and a way to explain conflicts to a human.

The Merge component provides the diff and three-way merge primitives used by those workflows. The default examples are line-oriented because that is the most familiar shape, but the strategy is intentionally pluggable: choose the differ, choose the merger, and optionally validate the merged result before accepting it.

Use the merge result to auto-accept independent edits and to show structured conflicts when a person must decide.

Diff two strings line by line
-----------------------------

[](#diff-two-strings-line-by-line)

Feed two strings to `LineDiffer` and inspect the operations. Every `get_changes()` entry is a `[op, text]` pair.
