Re: [Pharo-users] Smacc question

by Stephane Ducasse

what was strange is that this version <whitespace> : \s+; %root MultiListObject; %prefix XPML; modifiers_opt : | modifiers ; modifiers : modifier 'modifier' {{}} | modifiers modifier 'modifier' {{}} ; modifier : "public" 'token' {{Modifier}} | "protected" 'token' {{Modifier}} | "private" 'token' {{Modifier}} | "static" 'token' {{Modifier}} ; did not accept 'public static' I found that there were obsolete classes around and I reloaded SmaCC in a fresh image then regenerate this and my test pass now. So I will do the same for my solidity parser.

Hi StÃ©phane, can you send the complete grammar? The %root directive should have no impact on parse failures.

Apparently there is an interaction with the root directives.

Now I tried to hook modifier logic to test and I cannot have two modifiers. I thought that modifiers : modifier 'modifier' | modifiers modifier 'modifier' ; allows one to have 'public static' but apparently not so I'm totally confused.
