+
+ * Fixed a problem in the Lexer giving problems to assign tokens to all lexer
+ states at once. This is now possible by simply using "*" as the state name.
+ For instance this will add the token int_ to all lexer states:
+``
+ template <typename Lexer>
+ struct lexer : lex::lexer<Lexer>
+ {
+ lexer()
+ {
+ int_ = "[1-9][0-9]*";
+ this->self("*") = int_;
+ }
+ lex::token_def<int> int_;
+ };
+``
+ Note: the `self("*") = ...` must be executed after all lexer states have
+ been introduced to the lexer object.
+ * Fixed lexer lookahead. The lookahead operation is now evaluated using the
+ lexer state the `token_def` instance used as its argument is associated
+ with.
+ * Fixed a problem in the `multi_pass` iterator causing wrong tokens to be
+ returned to the user. This could happen in conjunction with a lexer which
+ performed lexer state changes and was using `pass_fail` in semantic actions
+ to make a token match fail.
