Regex how to match indented blocks

Question

I would like to match any block of indentation up to the next line with 0 whitespace. What I tried is this: ^[^\s](\w*|\s+) but this doesn't do what I need. My expectation is to math in a string like:

ajk
 sjdklj
fkldf fl kas dl  4jkl
   asdjk l    sdklj a wk
        ssdklj
4ksk adlj 2jklj

to have groups of matches:

Match 1

ajk
 sjdklj

Match 2

fkldf fl kas dl  4jkl
   asdjk l    sdklj a wk
        ssdklj

Match 3

4ksk adlj 2jklj

So in plain english: any block which starts with 0 whitespace (whitespaces and indentations are allowed inside the blocks). Any helps are appreciated.

Edit This ^[^\s]\w+.* matches first lines of indented blocks, but not the indented lines themselves.

Answer 1

You can try:

/(^\H.*(?:\n^\h+.*)*)/gm

Demo

Or:

/(^\S.*(?:\n^\h+.*)*)/gm

If you don't want to capture leading \n
