Immediately evaluate multiple lines of code at same time in rails console when using pry?

Question

Suppose we have pry installed, open the rails console, and run

times = [1, 5, 10, 30, 72].sample(1)[0]
nums = *(1..72)
num_sample = nums.sample(times)

Evaluation stops after line 2 (since the output of the second line runs off screen and hence the console opens the output):

How can we get the console to not stop executing, but rather display the entirety of the output of one line before executing the next, that is, to execute all lines of code it receives? Is there any way to achieve this without removing the pry-rails gem?

You can suppress the long output by doing something like this: `nums = *(1..72); nil` — Sergio Tulentsev, Sep 13 '20 at 14:08
@SergioTulentsev thanks :) - is there any way to to it without altering code? (e.g. what if you have 2000 lines ) Any global setting ? — stevec, Sep 13 '20 at 14:09
You're going to paste 2000 lines into pry? I don't think so :) — Sergio Tulentsev, Sep 13 '20 at 14:17
In this case, try this: https://github.com/pry/pry/wiki/Customization-and-configuration#Config_pager — Sergio Tulentsev, Sep 13 '20 at 14:20
@SergioTulentsev works perfectly. Thanks very much! (if you want to make it an answer, I will accept it) — stevec, Sep 13 '20 at 14:28

You can disable pry pager:

Disabling paging Permanently (in a .pryrc file)
Pry.config.pager = false
Temporarily (in a repl session)
pry_instance.config.pager = false

I just went to upvote the question and answer, and realised it was my question and I'd already upvoted the answer. Am I the only one that tries to do this. Is it an anti pattern of some sort? I need to drop multiple lines into the rails console fairly frequently. – stevec Dec 14 '20 at 06:18

@stevec: just a few days ago _I myself_ googled how to do this, found this answer and tried to upvote it :) – Sergio Tulentsev Dec 14 '20 at 09:12
