如何在 `rich.panel.Panel` object 中打印字典？

Question

As the question says, I want to pretty print a dictionary such as locals() but in a Panel object (surrounding the dictionary in a nice rectangle).

On trying the naïve approach, ie,

from rich.panel import Panel
from rich import print

print(Panel(locals()))

I'd get NotRenderableError: Unable to render...; A str, Segment or object with __rich_console__ method is required NotRenderableError: Unable to render...; A str, Segment or object with __rich_console__ method is required

The best I could do was convert the dictionary into a renderable by digging the source-code.

from rich.console import Console


def do(x):
    c = Console()
    print(Panel(c._collect_renderables(x, sep='\n', end='')))

do(globals())

But all it did was print the keys in a box

│ line_level    │                                                                            
│ n             │

Can anyone suggest the right document I must go through to accomplish this, and in general what is the right way to understand how to utilize rich to its fullest?

Answer 1

It turned out to be simpler than what I thought..

from rich import print
from rich.panel import Panel
from rich.console import Console
from rich.text import Text


def print_box(x, title=None):
    console = Console()
    with console.capture() as capture:
        console.print(x)
    str_output = capture.get()
    text = Text.from_ansi(str_output)
    print(Panel(text, title=title, padding=2))

1. Capture the text in a console output
2. Convert it to Text object, and
3. Display in a Panel
