Terminal

Inherits: Control < CanvasItem < Node < Object

Terminal emulator.

IMPORTANT:

  • If you are not seeing anything in the terminal check that a theme has been set. If there is no theme, everything will be drawn in black by default.
  • If the terminal isn't responding to keyboard or mouse input check that focus_mode is set to All, otherwise _gui_input() won't be called so no input will be processed.

Description

Flow Diagram

(1) User Input

The users enters some data into the terminal, typically by typing something on the keyboard or clicking (and possibly dragging) somewhere on the screen. This corresponds to the _gui_input() method which is implemented in terminal.cpp.

(2) Terminal Output

The user input from (1) is processed by the terminal and converted. For example, if the user were to press the down key, the terminal would and the data_sent signal would be emitted with the value "\u001b[A". For a full list of escape sequences "XTerm Control Sequences".

(3) Terminal Input

In the other direction, characters can be sent to the terminal. This corresponds to the write() method.

(4) Draw

The input from (3) is then intepreted by the terminal and drawn to the screen. For example if the string "\u001b[39;m" was written to the terminal, then it would draw some colorful output to the screen.

Signals

  • data_sent ( PoolByteArray data )

    Emitted when some data comes out of the terminal. This typically occurs when the user interacts with the terminal by typing on the keyboard or clicking somewhere. It might also occur. Depending on several terminal settings can be interpreted differently, depending on modifier keys and the terminals settings/state. In a typical setup, this data would be forwarded to the linux operating system.


  • key_pressed ( int row )

    Emitted when a key is pressed.

Property Descriptions

  • int rows

    Default 24
    Setter set_rows(value)
    Getter get_rows(value)

    The number of rows in the terminal's rect. When using a monospace font, this is typically the number of characters that can fit from one side to another. Therefore it is affected by the things thing.


  • int cols The number of columns in the terminal's rect.

Method Descriptions

  • void write ( String|PoolByteArray data )

    Writes data to the terminal emulator. Accepts either a String or PoolByteArray.

    Example:

    $Terminal.write("Hello World")
    $Terminal.write("Hello World".to_utf8())
    $Terminal.write(PoolByteArray([0x1b, 0x9e])
