Overview

Package buf owns the read-only terminal screen buffer contract for tests.

Boundary law:

• immutable observation surface only
• no timing/retry policy
• no fixture IO
• no runtime-driver concerns (pty, vt, retained loop)

Types

type MatrixView

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

Matrix is a concrete read-only screen view.

func FromString

func FromString(raw string) MatrixView

FromString builds a screen view from raw terminal text.

func FromStringWithViewport

func FromStringWithViewport(raw string, cols, rows int) MatrixView

FromStringWithViewport builds a screen view using fixed viewport bounds.

func (MatrixView) Cell

func (m MatrixView) Cell(x, y int) rune

func (MatrixView) Line

func (m MatrixView) Line(y int) string

func (MatrixView) Size

func (m MatrixView) Size() (cols, rows int)

func (MatrixView) String

type View

type View interface {
	Size() (cols, rows int)
	Cell(x, y int) rune
	Line(y int) string
	String() string
}

View is an immutable read-only terminal screen surface.
