Package difftest supplies a set of tests that will operate on any implementation of a diff algorithm as exposed by "golang.org/x/tools/internal/diff".

package lcs contains code to find longest-common-subsequences (and diffs).

Package myers implements the Myers diff algorithm.

Apply applies a sequence of edits to the src buffer and returns the result.

ApplyBytes is like Apply, but it accepts a byte slice.

Bytes computes the differences between two byte slices.

Merge merges two valid, ordered lists of edits.

SortEdits orders a slice of Edits by (start, end) offset.

Strings computes the differences between two strings.

ToUnified applies the edits to content and returns a unified diff, with contextLines lines of (unchanged) context around each diff hunk.

Unified returns a unified diff of the old and new strings.

DefaultContextLines is the number of unchanged lines of surrounding context displayed by Unified.

An Edit describes the replacement of a portion of a text file.
