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. A default theme can be found in the themes directory.
• 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

(1) User Input

The user 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 downwards arrow key (↓), the terminal would interpret this and the data_sent() signal would be emitted with the value "\u001b[A". For a full list of escape sequences see "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[38;2;0;255;0;mA" was written to the terminal, then it would draw a green colored capital letter 'A' on 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. Input can be interpreted differently depending on modifier keys and the terminal's settings/state.

  In a typical setup, this data would be forwarded to the pseudoterminal.

---

• key_pressed ( String data, InputEventKey event )

  Emitted when a key is pressed. data is the data that would be emitted by the terminal via the data_sent() signal and may vary based on the terminal's state. event is the event captured by Godot in the _gui_input(event) method.

---

• size_changed ( Vector2 new_size )

  Emitted when the terminal's size changes, typically in response to its rect_size changing. new_size.x will be the number of columns and new_size.y will be the number of rows. This information should be forwarded to a pseudoterminal if it is connected so that it can update its size accordingly.

Property Descriptions

• int rows

  Default	24
  Setter	None
  Getter	None

  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 the top to the bottom. It will automatically update as the Control's rect_size changes, and therefore shouldn't be used to set the size of the terminal directly.

---

• int cols

  Default	80
  Setter	None
  Getter	None

  The number of columns 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. It will automatically update as the Control's rect_size changes, and therefore shouldn't be used to set the size of the terminal directly.

Method Descriptions

• void write ( String|PoolByteArray data )

  Writes data to the terminal emulator. Accepts either a String or PoolByteArray. Typically it would be connected to the output of a pseudoterminal.

  Example:

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