[Feature Request] Make --extract work when there are multiple search results

[boggeroff]

Foreword: Trizen, your work is awesome.

System: Ubuntu 21
Version: CLI Pipe Viewer 0.1.3

I'm trying to use pipe-viewer to only extract information. Objective is to have search results, or the video links/IDs most importantly, saved to a file.

This,
pipe-viewer --no-interactive --extract '*TITLE* (*ID*)' --extract-file results.txt 'https://www.youtube.com/watch?v=zfFo8BtPTnc'
produces a file with contents:

Chico Xavier - Contos Desta e Doutra Vida (zfFo8BtPTnc)

The option "--dump json" is ignored.

It would be great if something like this,
pipe-viewer --no-interactive --extract '*TITLE* (*ID*)' --extract-file results.json --dump json --related 'https://www.youtube.com/watch?v=zfFo8BtPTnc'
would output a file with multiple results, instead of an empty file. Json or plain text.

A crappy solution to print related videos' ids of a video. Before anyone wants to extend this, consider learning Perl and contribute to the project. Which, I did consider myself but I can't be unfathful to python. And bash is already here as this irritable thing that can't be scraped off.

Install the expect package if you don't have it already.
Put this in an executable:

#!/usr/bin/bash
[ $# -lt 2 ] && { echo 'arg1: range; arg2: video link'; exit 1; }
expect_cmd=$(cat <<- END
spawn pipe-viewer --no-interactive --no-use-colors --std-in=":info=$1" --related "$2"
expect "=>> Press ENTER to continue..." { send "\r" }
expect eof
END
)
/usr/bin/expect -c "$expect_cmd" | grep VideoID | sed -E 's/.*VideoID\s+:\s+([a-zA-Z0-9_-]+)/\1/g'

Use it:

<exe> 1-3 'https://www.youtube.com/watch?v=123456789ab'
