I'm trying to add range operator in my language, and I'm having a problem with it.
The range operator is defined as following: range: INT '..' INT ; where INT is '0'..'9'+ I do have FLOAT, but it is defined such that it does not have conflict with the range operator: FLOAT: ('0'..'9')+'.'('0'..'9')+ EXPONENT? | ('0'..'9')+ EXPONENT ; The thing is, if I use the range operator with white spaces before & after the dots(such as 10 .. 100), it parses fine But without the white spaces(such as 10..100), it says 'MismatchedTokenException' . Can anyone see why it's acting like that? I do not use dot ('.') in any other places. I'm using antlrworks 1.4.3 for writing grammar and testing it (interpreter & debugger) Thanks.
