the [attribute] TOken should be changed from [global attributes] to [attributes] without a namespace












0














This question is about C# grammar sample of the Irony project.

The original grammar is found here: CSharpGrammar.cs.



This is my modified C# syntax, but the [attribute] non-terminal should be changed from [global attributes] to [attributes] without a namespace.



How can do it?



this.Root = compilation_unit;
compilation_unit.Rule = extern_alias_directives_opt
+ using_directives_opt
+ global_attributes_opt
+ namespace_member_declarations;

var global_attribute_target = new NonTerminal("global_attribute_target");

global_attribute_target.Rule = ToTerm("field") | "event" | "method" | "param" | "property" | "return" | "type";

global_attributes_opt.Rule = MakeStarRule(global_attributes_opt, null, global_attribute_section);
global_attribute_section.Rule = PreferShiftHere()+ "[" + global_attribute_target + colon + attribute_list + comma_opt + "]";

attribute_target_specifier_opt.Rule = Empty | attribute_target + colon;
attribute_target.Rule = ToTerm("field") | "event" | "method" | "param" | "property" | "return" | "type";
attribute_arguments_par_opt.Rule = Empty | Lpar + attribute_arguments_opt + Rpar;
attribute_arguments_opt.Rule = MakeStarRule(attribute_arguments_opt, comma, attr_arg);
attr_arg.Rule = identifier + "=" + expression | expression;


right

  • Why distinguish between global_attributes and attributes? Their syntax is the same, so why not use single non-terminal for both of them?
