stri_extract_all stops regex matching at newline #280

Closed atajti closed 7 years ago

atajti commented 7 years ago

After running the following code snippet, I expect to get "ing\nof inter":

tst_str <- "some string\nof interest"
stringi::stri_extract(tst_str, regex="ing.*ter")

However I get NA as result. After modifying to regex="ing.*", I expect "ing\nof interest" as result, however it gives "ing".

It also seems to be the case with 

stringi::stri_replace(tst_str, "000", regex="ing.*rest")
stringi::stri_replace(tst_str, "000", regex="ing.*")

Hi, RTM, see ?stringi::stri_opts_regex, HTH.

My bad, thanks for the pointer.
