Looking for a way to parse SNMP Mib Files in Ruby, I found a project written in Java (www.mibble.org) that use two files of Grammar (extension .grammar) to parser Mib files. Is there any way to use grammar files with ruby?

If you dig further you will see the grammar file is for Grammatica, which only supports Java and C#.
Either you extend Grammatica to support Ruby or you will have to switch to other approaches. Note that Mibble is released GPL and a commercial license. If you are going to reuse the grammar file, make sure you meet the licensing requirements.
