Types

type DiffHunk

type DiffHunk struct {
	OldStart int
	OldCount int
	NewStart int
	NewCount int
	Header   string
	Lines    []DiffLine
}

DiffHunk represents a hunk (group of changes) in a diff.

func ParseUnifiedDiff

func ParseUnifiedDiff(diffContent string) []DiffHunk

ParseUnifiedDiff parses a unified diff string into structured DiffHunks.

type DiffLine

type DiffLine struct {
	Content    string
	LineType   DiffLineType
	OldLineNum int
	NewLineNum int
}

DiffLine represents a single line in a diff with its metadata.

type DiffLineType

type DiffLineType string

DiffLineType represents the type of line in a diff.

const (
	DiffLineAdded   DiffLineType = "+"
	DiffLineRemoved DiffLineType = "-"
	DiffLineContext DiffLineType = " "
	DiffLineHunk    DiffLineType = "@@"
)

type Viewer

type Viewer struct {
	// contains filtered or unexported fields
}

Viewer is a component for viewing file diffs with line-by-line coloring.

func NewViewer

func NewViewer() *Viewer

NewViewer creates a new diff viewer component.

func NewViewerWithMaxWidth

func NewViewerWithMaxWidth(maxWidth int) *Viewer

NewViewerWithMaxWidth creates a new diff viewer with the given maximum width.

func (*Viewer) Focused

func (*Viewer) SetSize

func (dv *Viewer) SetSize(width, height int)

SetSize sets the dimensions of the diff viewer.

func (*Viewer) SetTheme

func (dv *Viewer) SetTheme(t theme.Theme)

SetTheme sets the theme for the diff viewer.

func (*Viewer) Update

func (dv *Viewer) Update(msg tea.Msg) (tea.Model, tea.Cmd)

Update implements tea.Model interface.

func (*Viewer) View

func (dv *Viewer) View() string

View implements tea.Model interface.
