Describe the Scenario

I don't consider this a BookStack bug but since BookStack has code blocks to make it easy to copy/paste code, I believe this "enhancement" is worth considering if it can be implemented.

ISSUE:

When coping multiple lines from a BookStack code block and pasting them into nano, in a terminal window, the new line characters are lost or replaced and some lines are out of order, as depicted in the image below:

It should look like the image below (copy/paste from EditPad Pro):

Work-around:

Copy code from the BookStack code-block, paste the code into a wordpad app such as EditPad Pro and then copy the text from the wordpad app and paste that into nano.

I get the same results with PuTTY, KiTTY, MobaXterm, etc. I'm working on a Windows PC. Not sure if that matters.

Thanks @jeffshead.

Not really sure where to take this for BookStack. We could change line endings depending on platform, which is what it looks like VSCode did, but I am hesitant since as far as I can tell we've always provided \n endings for code blocks, and it's hard to foresee the potential corner cases this change may affect and their significance relative to your scenario. It is something we can control though rather simply via CodeMirror config.

Having also a problem problem pasting into a console, or emacs... etc

copy/paste this code from a code block:

START TRANSACTION;
WITH delete_needed AS (
 select phone_directory_id from asterisk.v_phone_buttons where compressed_mac is null
)
DELETE FROM
 asterisk.phone_buttons
WHERE
 phone_directory_id IN (SELECT phone_directory_id FROM delete_needed)
RETURNING *
;

And it looks like this when using a straight console

The arrows are pointing to non-ascii characters that are getting pasted in... if you paste this into emacs it will completely mash up the paste where it looks like this:
