Re: repost of alike 'missing a way to extract data'

[Alex fxmbsw7 Ratchev]

what, dude, of course you can regex eerything right
that is, for no quotes
till non escaped end, ] probably
for " its till nonescaped "
and for $' till nonescaped '

i can regex it or extglob it
hm ?
but i need the results of grouping of the matches ( '( .. )' )
