  =rusty_grammar= is a library that makes use of a modified CYK algorithm to define grammars and understand language.

impl<'grammar> Grammar<'grammar> for G { fn convert(&self) -> Vec<GrammarRule<'grammar>> { let mut rules = Vec::new(); rules.push(GrammarRule{ left_symbol: "ActionSentence", right_symbol: "Verb NounClause | Verb NounClause PrepClause" }); rules.push(GrammarRule{ left_symbol: "NounClause", right_symbol: "Count ANoun | Adjective Noun" }); rules.push(GrammarRule{ left_symbol: "PrepClause", right_symbol: "Prep NounClause" }); rules.push(GrammarRule{ left_symbol: "ANoun", right_symbol: "Adjective Noun" }); rules.push(GrammarRule{ left_symbol: "Adjective", right_symbol: "adjective" }); rules.push(GrammarRule{ left_symbol: "Prep", right_symbol: "prep" }); rules.push(GrammarRule{ left_symbol: "Verb", right_symbol: "verb" }); rules.push(GrammarRule{ left_symbol: "Noun", right_symbol: "noun" }); rules.push(GrammarRule{ left_symbol: "Count", right_symbol: "definiteArticle | indefiniteArticle | number" }); rules } }

That's more code up front, but now the mod and use process is automatic. Add as many Rust files to =util= as you desire; the =use_glob= method will pick up and import all of them.\ To see an example using this directory structure, see [[https://github.com/Shizcow/proc_use/tree/master/examples/globbing][globbing]].
