[proposal] Maths rendering

[FedeClaudi]

Hi WIll,

Sorry I'm spamming you today, but I wanted to suggest an improvement for rich.
As far as I can tell there is no easy way to print beautifully formatted latex equations in rich (or in python in general it seems), but there is unicodeit which gets pretty close for simple inline maths expressions.

I was wandering if you'd be interested in integrating it in rich, it's very simple to use and the results are quite nice.

For instance:

from rich import print
from unicodeit import replace

class Math():
    def __init__(self, expression):
        self.expression = replace(expression)

    def __rich_console__(self, *args):
        yield self.expression

print(Math('\\alpha: \\Re \\to \\Im'))

gives:

though it might be simpler to just add replace to anything being printed: it leaves text unchanged, only tries to replace stuff that looks like a latex symbol. Of course it could be made optional for users that don't like it.

Let me know what you think of it!

I think unicodeit is so simple to use it doesn't need anything added to Rich. Like you said, it's easy to call replace as required. And if you prefer wrapping it in a renderable, that's just a few lines.

In general, these things are best left as external libraries. I wouldn't want to add too many dependancies in the main lib. If you wanted to, you could publish a rich-math library on Pypi...

that's a great idea!

Thanks
