Module line_diff 

Line-based diff algorithm for comparing saved vs current buffer content.

This module provides a simple but robust diff algorithm that correctly handles insertions, deletions, and modifications. It uses a longest common subsequence (LCS) approach to identify which lines are unchanged, then marks the ranges that differ.

Structs

LineChange

A range of lines with a specific change type

LineDiff

Result of comparing two text buffers line by line.

Enums

ChangeType

Type of change detected for a line range

Functions

diff_lines

Compare two byte slices line by line and return which lines in current differ from saved.

merge_ranges

Merge adjacent or overlapping ranges.
