Is it possible to fire up VisiData within Python?

[Shahin-rmz]

Hi, maybe you know me, because I am the old fan of Visidata from almost day zero.
The question is self explanatory.
I am getting sick of other types of showing dataframes and tabular data in Terminal with python.
Is it possible to open Visidata as python function and show the dataframe as visidata?

How?

For example Within jupyter cell, having a function, that when we call it, interactive or passive visidata opens up!

I don't know of a smooth way to do this from a jupyter cell 🤔 . Taking Jupyter out of the equation, you can use a flow like this from Python:

import pandas as pd
from visidata import vd

df = ...
vd.view_pandas(df)

...but the few times I've tried it from jupyter it hasn't worked well because visidata wants raw terminal access and jupyter is doing its own thing.

One workaround I've only used for example purposes is passing data into a running vd session. I'm assuming that's probably too janky to be a true solution, but maybe still useful in case it triggers any more productive impulses from folks like you who know your way around notebooks.

Are you sure that the code actually works?
I get this error

, in fail(vd, *args)
     69 'Abort with ExpectedException, and display *args* on status as a warning.'
     70 vd.status(*args, priority=2)
---> 71 raise ExpectedException(args[0] if args else '')

ExpectedException: raw() returned ERR

I am trying to open it with a loader.

Nope. It only earned the "works on my machine" badge.

Right. That's what I meant here:

...but the few times I've tried it from jupyter it hasn't worked well because visidata wants raw terminal access and jupyter is doing its own thing.

I don't use jupyter often so didn't have the traceback handy. But it looks like you're hitting the same trouble. Makes sense.

one year later and I still could not open visidata within my python apps.
is it possible?
@saulpw
I use vim and connect it to jupyter console.
As file manager I use vifm and it has a Plugin that we can fire up vifm inside vim. wanted to know if we can do the same to interact with our dataframes with Visidata inside python or vim.
Thanks

It works fine from the Python console and ipython:

from visidata import vd
vd.view('hello')

[Shahin-rmz]

You are right,
If I run my app with python3 main.py it works fine.
(I use jupyter vim integration) it sends codes inside a cell to a ipython instance run it.
in this case I get this error:

Yes, this is the same error @ajkerrigan showed above. Looks like Jupyter doesn't support curses raw() mode (used for TUIs). So it's not possible within Jupyter. Sorry.
