How to use rich.Progress with asyncio

[zhqu1148980644]

from rich.progress import (
    Progress,
    TextColumn,
    BarColumn,
    SpinnerColumn
)
process = Progress(
    TextColumn("[bold blue]{task.fields[a]}", justify="right"),
    BarColumn(bar_width=None),
    "[progress.percentage]{task.percentage:>3.1f}%",
    "•",
    TextColumn("{task.fields[b]}"),
    "-",
    TextColumn("{task.fields[c]}"),
    SpinnerColumn(),
    TextColumn("{task.fields[d]}"),
    "o"
)

task_id = process.add_task('test', a=1, b=1, c=1, d=1)
process.start_task(task_id)


async def show():
    a = b = c = d = 1
    while True:
        await asyncio.sleep(1)
        process.update(task_id, a=a + 1, b=b + 1, c=c + 1, d=d + 1)

with process:
    asyncio.run(show())

The process bar updated a few times, it looks like the while loop just ran a few times and then stopped.

My fault, the variable has never been updated.
