Python Rich Live not working in Intellij IDE

I have the following example of Rich Live from the official examples of Rich. (layout.py)

Code

from datetime import datetime

from time import sleep

from rich.align import Align
from rich.console import Console
from rich.layout import Layout
from rich.live import Live
from rich.text import Text

console = Console()
layout = Layout()

layout.split(
    Layout(name="header", size=1),
    Layout(ratio=1, name="main"),
    Layout(size=10, name="footer"),
)

layout["main"].split_row(Layout(name="side"), Layout(name="body", ratio=2))

layout["side"].split(Layout(), Layout())

layout["body"].update(
    Align.center(
        Text(
            """This is a demonstration of rich.Layout\n\nHit Ctrl+C to exit""",
            justify="center",
        ),
        vertical="middle",
    )
)


class Clock:
    """Renders the time in the center of the screen."""

    def __rich__(self) -> Text:
        return Text(datetime.now().ctime(), style="bold magenta", justify="center")


layout["header"].update(Clock())

with Live(layout, screen=True, redirect_stderr=False) as live:
    try:
        while True:
            sleep(1)
    except KeyboardInterrupt:
        pass

Problem

This works as expected when I do python layout.py in Powershell. But if I click on run via the IntelliJ IDE it is not working.

The following is my configuration enter image description here

Solution

  • Toggling the "Emulate terminal in output console" option in the Run configuration should fix the problem. If this option is unavailable in the run configuration, remove it from Run | Edit Configuration and create a new one by right-clicking the file in the editor, More Run/Debug | Modify Configuration. Also, the version of IDEA is a bit outdated; please consider updating to the latest.
