Functions

paint(placed, buffer)

@spec paint(Tuix.Layout.Placed.t(), Tuix.Buffer.t()) :: Tuix.Buffer.t()

Paints a placed tree into a buffer.

render(element, width, height)

@spec render(Tuix.Element.t(), pos_integer(), pos_integer()) :: Tuix.Buffer.t()

Renders an element tree at the given size: layout + paint.

to_iodata(new, old \\ nil)

@spec to_iodata(Tuix.Buffer.t(), Tuix.Buffer.t() | nil) :: iodata()

Serializes the difference between two frames as ANSI iodata.

With old as nil, serializes the full frame (preceded by a clear).

Rows whose contents are unchanged are skipped with a single term comparison. Within a changed row, consecutive changed cells are emitted as runs (one cursor move per run), in a single pass over the row.
