Perhaps with a grammar?

I have a string delimited by two characters: "\|"
_S=" 34 + 45 \| abc \| 1 2 3 \| c\|123abc "
which then I need to turn into a array looking like:
_S_AR=(
" 34 + 45"
" abc"
" 1 2 3"
" c"
"123abc"
)
I can't make awk or tr work in the way I need and all examples I
have found use only one character.
Is it possible to do such things in bash?

A single quoted string:
' 34 + 45 \| abc \| 1 2 3 \| c\|123abc '.split('\|').join(', ');
returns: 34 + 45 , abc , 1 2 3 , c, 123abc
A double quoted string interprets '\' so;
" 34 + 45 \| abc \| 1 2 3 \| c\|123abc ".split('|').join(', ')
returns: 34 + 45 , abc , 1 2 3 , c, 123abc
spaces are still left in. The join is used to show the strings in the
array a bit better.

Marcel

To:
I've slowly been learning the Raku programming language (AKA Perl6), and
while I'm far from being an expert, this is the first solution I came up
with (raku one-or-two-liners, at the bash command prompt):
user@mbook:~$ raku -e ' my Str $s=" 34 + 45 \| abc \| 1 2 3 \| c\|123abc ";
$s.put';
34 + 45 | abc | 1 2 3 | c|123abc
user@mbook:~$ raku -e ' my Str $s=" 34 + 45 \| abc \| 1 2 3 \| c\|123abc ";
$s.split("|").raku.put';
(" 34 + 45 ", " abc ", " 1 2 3 ", " c", "123abc ").Seq
user@mbook:~$ raku -e ' my Str $s=" 34 + 45 \| abc \| 1 2 3 \| c\|123abc ";
.put for $s.split("|");'
34 + 45
abc
1 2 3
c
123abc
user@mbook:~$ raku -e ' my Str $s=" 34 + 45 \| abc \| 1 2 3 \| c\|123abc ";
.raku.put for $s.split("|");'
" 34 + 45 "
" abc "
" 1 2 3 "
" c"
"123abc "
user@mbook:~$
Looking at the Str typed-variable $s I see that backslash escapes are
removed automatically (the second command only has to split on the pipe
character). So maybe this isn't a general solution, but it works for the
example given.
