Methods

applyPatch(String original, List<DiffHunk> hunks) → String

Apply a list of hunks to original text and return the result.

computeDiff(String oldText, String newText, {DiffAlgorithm algorithm = DiffAlgorithm.myers, int? contextLines}) → List<DiffHunk>

Compute the diff between oldText and newText.

computeDirectoryDiff(String oldDir, String newDir) → Future<List<FileDiff>>

Compute diffs for every file that differs between oldDir and newDir.

computeFileDiff(String oldPath, String newPath) → Future<FileDiff>

Compute a FileDiff by reading files at oldPath and newPath.

formatSideBySide(FileDiff diff, {int width = 120}) → String

Format a FileDiff as a side-by-side comparison.

formatUnifiedDiff(FileDiff diff, {int? contextLines}) → String

Format a FileDiff as a unified diff string.

highlightInlineDiff(String oldLine, String newLine) → (List<InlineSpan>, List<InlineSpan>)

Compute word-level inline diff between oldLine and newLine.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

parsePatch(String patchText) → List<FileDiff>

Parse a unified diff / patch string into a list of FileDiff.

reversePatch(List<DiffHunk> hunks) → List<DiffHunk>

Reverse a patch so that applying the reversed hunks undoes the original.

threeWayMerge(String base, String ours, String theirs) → MergeResult

Perform a three-way merge between base, ours, and theirs.

toString() → String

A string representation of this object.
