[rules-users] rule name regular expression

[Edson Tirelli]

    Hi, yes, close to that:

name returns [String name]
    :     ID { $name = $ID.text; }
    |     STRING { $name = getString( $STRING.text ); }
    ;

    So, a rule name can be either an ID or a STRING. ID is what you got
already:

ID
    :
('a'..'z'|'A'..'Z'|'_'|'$'|'\u00c0'..'\u00ff')('a'..'z'|'A'..'Z'|'_'|'0'..'9'|'\u00c0'..'\u00ff')*

    ;

    A String is a valid Java string... so pretty much anything enclosed in
either " or '.

STRING
    :  ('"' ( EscapeSequence | ~('\\'|'"') )* '"')
     | ('\'' ( EscapeSequence | ~('\\'|'\'') )* '\'')
    ;

    In other words, if you want to allow the user to write rule names and
don't want to bother in validating it, just enclose the rule name in " and
be done with it. The only thing that may be good is to limit the length of
the string... you may want to use a hard limit around 60 characters I guess.
