Regarding expecting next grammar rules #2276

Open Krypton3 opened 6 years ago

Krypton3 commented 6 years ago

Hello, I am new to writing antlr4 grammar. I have written this sentence. gby : 'by' cn+ hvg? ;

Testing rules: line 1:0 mismatched input '' expecting 'by' input: by line 1:2 missing 'CN' at '' input: by CN but after inputing by CN I don't get expecting "hvg" as a suggestion because of "?" sign. But I want to get suggestion for "hvg". It would be great if anyone tells me how can I get this suggestion. Thank in advance.
