Textual: Terminal

A terminal widget for Textual using Pyte as a linux terminal emulator.

Textual application example with two terminal widgets:

Usage

from textual_terminal import Terminal

class TerminalApp(App):
    def compose(self) -> ComposeResult:
        yield Terminal(command="htop", id="terminal_htop")
        yield Terminal(command="bash", id="terminal_bash")

    def on_ready(self) -> None:
        terminal_htop: Terminal = self.query_one("#terminal_htop")
        terminal_htop.start()

        terminal_bash: Terminal = self.query_one("#terminal_bash")
        terminal_bash.start()

Installation

pip install textual-terminal

Features

• Colored output
• Automatic resize to widget dimensions
• Simple key handling (navigation, function keys)
• Simple mouse tracking (click, scroll)

Options

default_colors

By default, textual-terminal uses the colors defined by the system (not the Textual colors). To use the Textual background and foreground colors for "default" ANSI colors, set the option default_colors to textual:

Terminal(command="htop", default_colors="textual")

Note: This only applies to ANSI colors without an explicit setting, e.g. if the background is set to "red" by an application, it will stay red and the option will not have any effect.
