Regex split string by new line and also include empty lines new lines

Question

my_line = [[this
is
a

test]]

split_file = string.match(my_line, "[^
]+|^[ 	
]*$")
print(#split_file)

the above code doesn't work and I don't know why

string.match(my_line, "[^
]+")

This works, but it only matches the words, so my array would look like this ["this", "is", "a", "test"]

While I want the array to be

["this", "is", "a", "
", "test"]

Not sure which language are you using, so in JavaScript using global (g) and multi-line (m) flags -

st = `this
is
a

test`;
console.log(JSON.stringify(st.match(/[^
]+|^[ 	
]*/gm))); // ["this","is","a","
","test"]
