Java regex capture EOL, regex over stream -

i'm trying implement regex on stream (reader). i'm using following approach:

1. read n chars buffer
2. call matcher.find() on buffer
3. trim beginning till matcher.end() position , append buffer n chars length
4. loop

there issue regex ^(.*)$ (it user data , not possible change it). matcher did not capture line endings, matcher.end() returns last symbol before \n char not \n itself. , after program loops in empty string. e.g. have input "abc\ncde"

• matcher captures abc , matcher.end() returns 2
• substring(2) returns "\ncde"
• matcher captures empty string , loops here

is there way make mather include eol chars capturing group? or there regex implementations java work streams?

p.s. there 1 solution ugly, not wont implement it:

string text = "abc\r\ndef\r\nghi\r\n"; pattern pattern = pattern.compile("^(.*)$", pattern.multiline); boolean first = true; matcher matcher = pattern.matcher(text); while (matcher.find(first ? 0 : 1)) {     system.out.println(matcher.group());     text = text.substring(matcher.end() - 1);     matcher.reset(text);     first = false; }
