I am trying to implement a grammar that may have 0 or more of a construct. Effectively I want to have a grammar like this:
File: ( Module )* I've looked through the manual and it appears bison does not support this construct, I was trying to replicate it. I've tried two ways: File: Module File | ; And File: File File | Module | ; The problem with the first approach is that it just selects the epsilon production on a file that has a module in it (it never selects the first production). The problem with the second approach is that it can't handle more than one Module in a row. It just loops until there is a stack overflow (I get a warning about the first production of that rule). What am I doing wrong? (I should mention that this is my first heavily expanded use of Bison. I was using ANTLR, but I didn't like the library dependencies, so I moved to Bison. ANTLR does support the ( Module )* construct so this was never an issue.
