- 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](../../themes).
|
|
- 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](./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"](https://invisible-island.net/xterm/ctlseqs/ctlseqs.html).
|
|
|
|
### (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:
|
|
```gdscript
|
|
$Terminal.write("Hello World")
|
|
$Terminal.write("Hello World".to_utf8())
|
|
$Terminal.write(PoolByteArray([0x1b, 0x9e])
|
|
```
