Interface IVTParserHandler

Interface for handling events emitted by the VTParser. Implementations receive parsed VT/ANSI escape sequence events and translate them into terminal state mutations.

Namespace: Scylla.TextMode

Assembly: ScyllaTextMode.dll

Syntax

public interface IVTParserHandler

Methods

CSIDispatch(ReadOnlySpan<int>, ReadOnlySpan<byte>, byte)

A CSI (Control Sequence Introducer) sequence has been parsed. CSI sequences are the primary mechanism for cursor movement, erasing, SGR, etc.

Declaration

void CSIDispatch(ReadOnlySpan<int> parameters, ReadOnlySpan<byte> intermediates, byte finalByte)

Parameters

Type	Name	Description
ReadOnlySpan<int>	parameters	Parsed numeric parameters (semicolon-separated in the escape sequence).
ReadOnlySpan<byte>	intermediates	Intermediate bytes (between CSI and final byte).
byte	finalByte	The final byte that identifies the specific command.

DCSHook(ReadOnlySpan<int>, ReadOnlySpan<byte>, byte)

A DCS (Device Control String) sequence is starting.

Declaration

void DCSHook(ReadOnlySpan<int> parameters, ReadOnlySpan<byte> intermediates, byte finalByte)

Parameters

Type	Name	Description
ReadOnlySpan<int>	parameters	Parsed numeric parameters.
ReadOnlySpan<byte>	intermediates	Intermediate bytes.
byte	finalByte	The final byte.

DCSPut(byte)

Data within a DCS passthrough sequence.

Declaration

void DCSPut(byte data)

Parameters

Type	Name	Description
byte	data	The passthrough byte.

DCSUnhook()

A DCS sequence has ended.

Declaration

void DCSUnhook()

ESCDispatch(ReadOnlySpan<byte>, byte)

An ESC (Escape) sequence has been parsed. Used for simpler sequences like DECSC, DECRC, and character set selection.

Declaration

void ESCDispatch(ReadOnlySpan<byte> intermediates, byte finalByte)

Parameters

Type	Name	Description
ReadOnlySpan<byte>	intermediates	Intermediate bytes.
byte	finalByte	The final byte.

Execute(byte)

A C0 or C1 control character should be executed. Common controls: BEL (0x07), BS (0x08), HT (0x09), LF (0x0A), CR (0x0D).

Declaration

void Execute(byte control)

Parameters

Type	Name	Description
byte	control	The control byte.

OSCDispatch(ReadOnlySpan<byte>)

An OSC (Operating System Command) sequence has been parsed. Used for window title, hyperlinks, clipboard, etc.

Declaration

void OSCDispatch(ReadOnlySpan<byte> data)

Parameters

Type	Name	Description
ReadOnlySpan<byte>	data	The raw OSC data bytes.

Print(int)

A printable character should be displayed at the current cursor position.

Declaration

void Print(int codepoint)

Parameters

Type	Name	Description
int	codepoint	Unicode codepoint to print.
