Re: [Spirit-general] Problem with Parsing

Joel:

On your suggestion, I used the debugging and found that if I replace

FILE >> LEFT_BRACE >> *(anychar_p) >> RIGHT_BRACE

by a real rule like 

FILE >> LEFT_BRACE >> A_REAL_RULE >> RIGHT_BRACE

then it works OK. What was strange was that the debugger indicated 
that the entire input file was consumed by the first original code 
and all that was left was "" and it still said parser failed. Any 
insight into it?

Thanks.
