I'm writing a parser for the very first time and I can't seem to resolve a reduce/reduce conflict the elegant way I want to use. (Yes, I'm writing my own SQL parser. Yes, I know there's modules that do this. Yes, I have a reason to do so.)
database_ident:
ident
;
table_ident:
database_ident '.' ident
| ident
;
column_ident:
table_ident '.' ident
| ident
;
ident:
IDENT
| IDENT_QUOTED
;
Parse::Yapp is complaining about 2 reduce/reduce conflicts whenever I try to use column_ident. If I manually expand table_ident and database_ident in the dependent rules, the reduce/reduce conflicts go away. But, I don't want to do that because I anticipate extending those rules over time and don't want to have the rule in multiple places. Does anyone have any suggestions?
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
