Question: gradual transition from standard command line application with prints() to textual app

[menteora]

Hi, I've been using this library recently, and it seems fantastic.

I would like to gradually manage the transition from a command-line app to a textual app. Therefore, I would like to convert all the initial print() statements in the old app into prints within a textual window with a header and footer. Is it possible?

from textual.app import App, ComposeResult
from textual.widgets import RichLog
from textual.widgets import Header, Footer
from textual.containers import VerticalScroll

class RichLogApp(App):
    def compose(self) -> ComposeResult:
        yield Header(self.title)
        yield Footer()
        yield VerticalScroll(
            RichLog(highlight=True, markup=True)
        )

    def print(self, message):
        text_log = self.query_one(RichLog)
        text_log.write(message)

if __name__ == "__main__":
    app = RichLogApp()
    app.run()
    app.print('your message here')
    app.print('your message here 2')

Of course, the code I've written doesn't work because the run() function is blocking the execution of the code.

Is there a way to achieve the result I'm looking for?

Thank you
