[QUESTION]The live module can't refresh as expected.

Hi there. I want to use rich.live module to show something in real time and I test it with your sample code.

import time

from rich.live import Live
from rich.table import Table

table = Table()
table.add_column("Row ID")
table.add_column("Description")
table.add_column("Level")

with Live(table, refresh_per_second=4):  # update 4 times a second to feel fluid
    for row in range(12):
        time.sleep(0.4)  # arbitrary delay
        # update the renderable internally
        table.add_row(f"{row}", f"description {row}", "[red]ERROR")

However, it did’t refresh, just show the final result for me. Could you give me some ideas how to use this module correctly?

As a quick work around

In powershell run:

$env:TERM="SMART"

Then re-run the initial code.

Thanks a lot, it works!

Thanks for diagnosing that @nathanrpage97

is_dumb_terminal will be True if TERM is set to “dumb” or “unknown”. As far as I know, this convention should apply to Windows.

@DarrenIce Do you recall adding the TERM environment variable? Could have been a workaround for an app that broken on Windows.

Yes, I add two lines in my code, and now it can work as expect.

self.console = Console(force_terminal=True,color_system='truecolor')
self.console._environ['TERM'] = 'SMART'
