a problem with 1..8

[Xue-Feng Yang]

I need to parse the language like "1..8" for an index loop. However, I have float literal in the grammar so that JavaCC recognizes "1." as a float literal and it expects ".." before ".8"(again, ".8" is a float literal too.).

How do I resolve this problem?

Thanks.

Shouldn't be too hard. Just define another token that looks for two periods.

Place this above the token definition for float literals, and you should be set.

That would be ugly in my case.

Actually, in this language, only number literal is defined as either integer literal or float literal. In other words, there is no difference in language for integer and float. This is a specification.

On the other hand, it's not a good idea to mix token definition and syntax definition.

I misunderstood. I'll try.
