Types

type MetadataService

type MetadataService struct {
	Runner gitexec.GitRunner
}

MetadataService lists files changed between two commits.

func (*MetadataService) ListFiles

func (s *MetadataService) ListFiles(ctx context.Context, cmp model.ResolvedCompare) ([]model.FileSummary, error)

ListFiles returns file summaries in the order emitted by git diff --name-status. It runs two git commands (--name-status -z and --numstat -z), parses the NUL-delimited output, and merges counts into the authoritative ordering.

type OversizedError

type OversizedError struct {
	Bytes int
	Lines int
}

OversizedError wraps ErrOversized with the measured byte size and line count so the UI can display them in the fallback message.

func (*OversizedError) Error

func (e *OversizedError) Error() string

func (*OversizedError) Unwrap

func (e *OversizedError) Unwrap() error

type PatchService

type PatchService struct {
	Runner gitexec.GitRunner
}

PatchService loads and parses unified diffs for individual files.

func (*PatchService) LoadPatch

func (s *PatchService) LoadPatch(ctx context.Context, cmp model.ResolvedCompare, filePath string, status model.FileStatus, ignoreWhitespace bool) (model.FilePatch, error)

LoadPatch runs git diff --patch for a single file and parses the result. For untracked files (status == StatusUntracked), it uses --no-index against /dev/null.
