Rendering Rich objects in Prompt-toolkit widgets

[byt3bl33d3r]

Heya,

I'm trying to render Rich tables in a full screen prompt-toolkit application in the TextArea widget. Is there a way turning Rich objects into a string , or some other way that is recommended to do this?

Thanks

Yep https://rich.readthedocs.io/en/stable/console.html

See the Capturing Output section...

I completely missed that... (and I don't know how). thanks again and sorry for the bother.

@byt3bl33d3r I don't suppose you have any examples for wiring this up? I'm interested in using prompt-toolkit to add some key-bindings to my Rich dashboard.

Hi, I have code:

from prompt_toolkit.application import Application
from prompt_toolkit.layout.containers import HSplit
from prompt_toolkit.layout.layout import Layout
from prompt_toolkit.widgets import TextArea
from prompt_toolkit.widgets.base import HorizontalLine


from io import StringIO
from rich.console import Console

console = Console(file=StringIO(), highlight=True, force_terminal=True, color_system="truecolor")

def main():

    hl = HorizontalLine()
    output_field = TextArea()
    area = TextArea(height=1, prompt=">>> ", style="class:input-field", multiline=False, wrap_lines=False, )
    input_field = area
    container = HSplit(
        [
            output_field,
            hl,
            input_field,
        ]
    )

    console.print("[bold]Hello!")
    txt = console.file.getvalue()
    output_field.text = txt

    application = Application(
        layout=Layout(container, focused_element=input_field),
        full_screen=True,
    )
    application.run()


if __name__ == "__main__":
    main()

why is it rendering rich objects not correctly ?

Try:

from prompt_toolkit.formatted_text import ANSI, to_formatted_text
txt = to_formatted_text(ANSI(console.file.getvalue())

The ANSI text that rich writes to the console or capture string needs be converted to prompt toolkit’s implementation of formatted strings first, it doesn’t just pass through the ANSI sequences.
