There are parameters (you can specify several of these at the same time):



'i': ONIG_OPTION_IGNORECASE;

'x': ONIG_OPTION_EXTEND;

'm': ONIG_OPTION_MULTILINE;

's': ONIG_OPTION_SINGLELINE;

'p': ONIG_OPTION_MULTILINE | ONIG_OPTION_SINGLELINE;

'l': ONIG_OPTION_FIND_LONGEST;

'n': ONIG_OPTION_FIND_NOT_EMPTY;

'e': eval() resulting code



And there are "modes" (if you specify several of these, the LAST one will be used):

'j': ONIG_SYNTAX_JAVA;

'u': ONIG_SYNTAX_GNU_REGEX;

'g': ONIG_SYNTAX_GREP;

'c': ONIG_SYNTAX_EMACS;

'r': ONIG_SYNTAX_RUBY;

'z': ONIG_SYNTAX_PERL;

'b': ONIG_SYNTAX_POSIX_BASIC;

'd': ONIG_SYNTAX_POSIX_EXTENDED;



You can find descriptions of these constants here: http://www.geocities.jp/kosako3/oniguruma/doc/API.txt
