using mapfile instead of read ( require v4 bash )

[elreydetoda]

So, first off this seems like a really awesome project 🙂 I love me some bash 😁. So, thank you for making this. One of my friends linked to it for something they were doing 🙂

Maybe there is another reason that you didn't use mapfile before, but since you are requiring v4+ anyways ( and mapfile was released in v4). Then I think this is a slightly less complex version of the same command. Maybe you were trying to be a bit more explicit for visual understanding of how things get split up ( setting IFS and everything ), but I get the same output when I run those example commands.

$ split() { mapfile -t arr <<< "${1//$2/$'\n'}";    printf '%s\n' "${arr[@]}"; }
$ split "apples,oranges,pears,grapes" ","
apples
oranges
pears
grapes
$ split "1, 2, 3, 4, 5" ", "
1
2
3
4
5

Let me know if there is anything I can do to help 🙂 or if there is anything else I need to add ( tests, etc... ).
I look forward to looking more into this pure bash bible 😁
