import os

from textual import on, work
from textual.app import App, ComposeResult, events
from textual.widgets import *


class ScriptApp(App):
    def compose(self) -> ComposeResult:
        yield Button("Submit", variant="primary", id="button")
        yield Output(highlight=True)

    def on_button_pressed(self, event: Button.Pressed) -> None:
        self.query_one(RichLog).clear()
        self.query_one(RichLog).begin_capture_print()

        if event.button.id == "button":
            baseSHA = 12345

            headSHA = 67890

            print(
                f"\033[1;31mPlease check if the {baseSHA} and\033[0m{os.linesep}\033[1;31mthe {headSHA} are in the same repository!\033[0m"
            )

            print("Writing comments...")

            print(f"\033[1;32mSuccessful\033[0m")


class Output(RichLog):
    @on(events.Print)
    def on_print(self, event: events.Print) -> None:
        if event.text.strip():
            self.write(event.text)


app = ScriptApp()

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

Would like to print

It prints

Can I just check as I've been down this rabbit hole before: does your logging actually involve some sort of subprocess and this code is just a MRE?

[Tim-Cao]

The above code is a MRE.

[TomJGooding]

Thanks, sorry but just wanted to ensure you actually needed to capture print at all. There was a recent discussion where after much back-and-forth it turned out they just wanted coloured text.

Try instead logging Text.from_ansi.

[Tim-Cao]

It works. Many thanks @TomJGooding

    @on(events.Print)
    def on_print(self, event: events.Print) -> None:
        if event.text.strip():
            self.write(Text.from_ansi(event.text))
