Setting global floating number length

[lainisourgod]

Hi! I want to round all floating numbers like I do in f"{number:0.3}". I can do this for bare numbers that I have in context, but if some object with numbers inside is pretty-printed, I can't change floats' formatting.

>>> object_with_floats = {"a": 1.287777777778124, "b": [1.21242141244, -12.2124142214444444444]}
>>> rich.print(objects_with_floats)
{"a": 1.287777777778124, "b": [1.21242141244, -12.2124142214444444444]}

What I want

Hmm. Rich doesn't attempt to do more with the data than repr would do.

I'd consider it. Could you propose how you would like it to work?

I'm glad you consider this to be a viable feature.

I failed to find how rich's repr works and where should this logic be put internally. I guess during tree traversal for every float we should call

def format_float(number: float, pattern: str) -> str:
    """
    pattern is a format-pattern from https://pyformat.info/
    e.g. "{:.3f}"
    """
     return pattern.format(number)

Then we can add pattern argument to log and print calls

console.log({1: {2: 123.4567890, 3: -35.7674}}, float_format_pattern="{:.3f}")

Also we can extend this functionality to format not only floating points but also regular numbers or strings via a Mapping argument:

console.log({1: {2: 123.4567890, 3: -35.7674}}, format_patterns={float: "{:.3f}", str: "{:>10}"})

I'd love to take a crack at implementing this, if it's still of interest to anyone?

Approximately all calls I make to the Rich print method look like rprint(round(num, 3)) or some equivalent, so this would make my logging code a lot prettier. I can see few instances when you'd ever want to actually print a float in its full glory.
