Detailed Description

FXRex is a regular expression class implementing a NFA matcher. It supports capturing parentheses, non-capturing parentheses, positive or negative lookahead, backreferences, case-insensitive matching, counted repetitions, lazy or greedy matches, and PERL-like matching operators. The subject string may be scanned forwards or backwards, and may contain any of 256 possible character values.

When parsing a regular expression pattern, the mode parameter is the bitwise OR of a set of flags and affects the match algorithm. Passing the flag REX_CAPTURE enables capturing parentheses and back references. The flag REX_ICASE enables case-insensitive matching. When the flag REX_NEWLINE is passed, newlines are treated like normal characters; otherwise, newline is NOT matched except when explicitly part of a character class. The flag REX_VERBATIM disables all special character interpretation.

When matching a compiled pattern, the mode parameter is the bitwise OR of a set of flags that affects how the match is performed. Passing the flag REX_BACKWARD causes the match to proceed backwards through the subject string. Passing the flags REX_NOT_BOL and/or REX_NOT_EOL causes the begin and end of the subject string NOT to be considered a line start or line end. The flag REX_NOT_EMPTY causes a match to fail if the empty string was matched.
