source

public property string source()

The regular expression pattern without delimiters and flags.

Returns the regular expression pattern without the forward slash delimiters and flags. Thus, /abc+/i will return abc+.

Although the JS++ grammar is an augmentation of the ES3 JavaScript grammar, source conforms to ES5 and will return (?:) if the regular expression pattern is empty. Furthermore, as in ES5, line terminators are escaped.
