Description

Match option enumeration set for the Perl regular expression.

Option	Meaning
preCaseLess	Tries to match the regex without paying attention to case. If set, 'Bye' will match 'Bye', 'bye', 'BYE' and even 'byE', 'bYe', and so on. Otherwise, only 'Bye' will be matched. Equivalent to Perl's /i modifier.
preMultiLine	The ^ (beginning of string) and $ (ending of string) regex operators will also match right after and right before a new line in the Subject string. This effectively treats one string with multiple lines as multiple strings. Equivalent to Perl's /m modifier.
preSingleLine	Normally, dot (.) matches anything but a new line (\n). With preSingleLine, dot (.) will match anything, including new lines. This allows a multiline string to be regarded as a single entity. Equivalent to Perl's /s modifier. Note that preMultiLine and preSingleLine can be used together.
preExtended	Allow the regular expression to contain extra white spaces, new lines, and Perl-style comments, all of which will be filtered out. This is sometimes called "free-spacing mode".
preAnchored	Allows the regular expression to match only at the start of the subject or right after the previous match.
preUnGreedy	Repeat operators (?, *, +, {num,num}) are greedy by default, for example, they try to match as many characters as possible. Set preUnGreedy to use ungreedy repeat operators by default, for example, so that they try to match as few characters as possible.
preNoAutoCapture	Allows the regular expression to capture only named groups. Note that (group) is a non-capturing group.
