Struct Cell

Namespace

Retro.Crt

Assembly

Retro.Crt.dll

One cell of a ScreenBuffer: a single glyph plus the foreground / background / attributes the diff renderer should paint it with. Value-equality so cell-by-cell diffing is a straight ==.

public readonly record struct Cell : IEquatable<Cell>

Implements

IEquatable<Cell>

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

Glyph is a single 16-bit char — surrogate pairs and wide East-Asian glyphs are not modeled in v1; one cell == one column. The name leaves room for a later grapheme-cluster representation without renaming the field.

Use Empty as the default-fill for an unwritten buffer: space on light-gray-on-black, the closest analogue of an empty terminal row.

Constructors

Cell(char, Color, Color, CellAttrs)

One cell of a ScreenBuffer: a single glyph plus the foreground / background / attributes the diff renderer should paint it with. Value-equality so cell-by-cell diffing is a straight ==.

public Cell(char Glyph, Color Fg, Color Bg, CellAttrs Attrs = CellAttrs.None)

Parameters

Glyph char

Fg Color

Bg Color

Attrs CellAttrs

Fields

Empty

Default empty cell — ASCII space on the classic DOS palette (LightGray on Black). Use this as the fill for a freshly created buffer.
