PCRE2 - Perl-compatible regular expressions (revised API)


       #include <pcre2.h>

       int pcre2_set_compile_extra_options(pcre2_compile_context *ccontext,
         uint32_t extra_options);


       This  function sets additional option bits for pcre2_compile() that are
       housed in a compile context. It completely replaces all the  bits.  The
       extra options are:

         PCRE2_EXTRA_ALLOW_LOOKAROUND_BSK     Allow \K in lookarounds
         PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES  Allow \x{d800} to \x{dfff}
                                                in UTF-8 and UTF-32 modes
         PCRE2_EXTRA_ALT_BSUX                 Extended alternate \u, \U, and
                                                \x handling
         PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL    Treat all invalid escapes as
                                                a literal following character
         PCRE2_EXTRA_ESCAPED_CR_IS_LF         Interpret \r as \n
         PCRE2_EXTRA_MATCH_LINE               Pattern matches whole lines
         PCRE2_EXTRA_MATCH_WORD               Pattern matches "words"

       There is a complete description of the PCRE2 native API in the pcre2api
       page and a description of the POSIX API in the pcre2posix page.
