How to keep correct inline app output in terminal for Input widget?

[robvanderleek]

I have a simple inline app (full code below) that just displays a label and waits for input:

Enter your name:

I want to keep the content on screen after exiting, so I'm using inline_no_clear=True.
However, after the user enters a name, the screen looks like this:

Enter your name: Rob Enter your name: Rob

Hello, Rob!

I've tested other widgets, and they work fine with the inline_no_clear=True flag.
I guess this is related to the "enter" key used for submitting input, but I don't understand what I'm doing wrong.

Code:

from textual.app import App
from textual.app import ComposeResult
from textual.containers import HorizontalGroup
from textual.widgets import Input, Label


class TextApp(App[str]):
    INLINE_PADDING = 0
    CSS = """
        App {
            background: black 0%;
        }
        Screen {
            border-top: none;
            border-bottom: none;
            background: black 0%;
        }
        Label {
            margin-right: 1;
        }
        Input {
            border: none;
            background: black 0%;
            padding: 0;
            height: 1;
        }
        """

    def __init__(self, message: str):
        super().__init__()
        self.message = message

    def on_input_submitted(self, event: Input.Submitted) -> None:
        self.exit(event.value)

    def compose(self) -> ComposeResult:
        with HorizontalGroup():
            yield Label(self.message)
            yield Input()


def text(message: str) -> str:
    app = TextApp(message)
    return app.run(inline=True, inline_no_clear=True)


if __name__ == "__main__":
    name = text("Enter your name:")
    print(f'Hello, {name}!')

This looks like a bug. Pressing ctrl+q to quit also results in garbled output, but only with the Input widget from a quick test:

from textual.app import App, ComposeResult
from textual.widgets import Button, Input


class ExampleApp(App):
    def compose(self) -> ComposeResult:
        # yield Button("Press ctrl+q to quit")
        yield Input("Press ctrl+q to quit")


if __name__ == "__main__":
    app = ExampleApp()
    app.run(inline=True, inline_no_clear=True)

Thanks for validating, I've submitted a bug issue.
