&gt; Hi,community:
&gt; 1. when I add binaryOpratorsTokens in default_config.fmpp, like
&gt; binaryOperatorsTokens: [
&gt;&nbsp;&nbsp; "< INFIX_CAST: \"::\" &gt;"]
&gt; what should I do next?
&gt;
&gt; 2. when I add extraBinaryExpressions: [ InfixCast]
&gt;
&gt; where can I define the Parser method
&gt;
&gt;
