textualeffects

Visual effects for Textual, a TerminalTextEffects wrapper.

Intro

textualeffects is a library that provides Textual bindings for the excellent TerminalTextEffects visual effects library.

Widgets

There are two widgets available in textualeffects, EffectLabel and SplashScreen.

An EffectLabel widget that can be used to display text with a visual effect.

from textual.app import App, ComposeResult

from textualeffects.effects import EffectType
from textualeffects.widgets import EffectLabel

text=("Hello World! " * 5 + "\n") * 10,
effect: EffectType = "Spotlights"
config = {
    "search_duration": 500,
    "spotlight_count": 3,
}


class TextualEffect(App):

    def compose(self) -> ComposeResult:
        label = EffectLabel(text, effect=effect, config=config)
        label.styles.border = ("heavy", "green")
        yield label


if __name__ == "__main__":
    app = TextualEffect()
    app.run()

A SplashScreen widget that can be used to display a splash screen based on ModalScreen with a visual effect. Once the effect is complete, the splash screen will be dismissed.

from textual.app import App, ComposeResult
from textual.widgets import TextArea

from textualeffects.effects import EffectType
from textualeffects.widgets import SplashScreen

effect: EffectType = "Spotlights"
config = {
    "search_duration": 100,
    "spotlight_count": 3,
}


class SplashEffect(App):

    def on_mount(self) -> None:
        text = ("Hello World! " * 5 + "\n") * 10
        self.push_screen(SplashScreen(text, effect=effect, config=config))

    def compose(self) -> ComposeResult:
        yield TextArea(("Main content" * 5 + "\n") * 10)


if __name__ == "__main__":
    app = SplashEffect()
    app.run()

Both widgets accept the following arguments:

• text: The text to display.
• effect: The visual effect to apply to the text. Available effects are exposed through the EffectType type.
• config: A dictionary of configuration options for the effect. The available options depend on the effect. Detailed information on the available options can be found in the TerminalTextEffects documentation.
