mod.rs Abstract Syntax Tree representation of the Fluent Translation List. The AST of Fluent contains all nodes structures to represent a complete representation of the FTL resource. The tree preserves all semantic information and allow for round-trip of a canonically written FTL resource. The root node is called [`Resource`] and contains a list of [`Entry`] nodes representing all possible entries in the Fluent Translation List. # Example ``` use fluent_syntax::parser; use fluent_syntax::ast; let ftl = r#" ## This is a message comment hello-world = Hello World! .tooltip = Tooltip for you, { $userName }. "#; let resource = parser::parse(ftl) .expect("Failed to parse an FTL resource."); assert_eq!( resource.body[0], ast::Entry::Message( ast::Message { id: ast::Identifier { name: "hello-world" }, value: Some(ast::Pattern { elements: vec![ ast::PatternElement::TextElement { value: "Hello World!" }, ] }), attributes: vec![ ast::Attribute { id: ast::Identifier { name: "tooltip" }, value: ast::Pattern { elements: vec![ ast::PatternElement::TextElement { value: "Tooltip for you, " }, ast::PatternElement::Placeable { expression: ast::Expression::Inline( ast::InlineExpression::VariableReference { id: ast::Identifier { name: "userName" } } ) }, ast::PatternElement::TextElement { value: "." }, ] } } ], comment: Some( ast::Comment { content: vec!["This is a message comment"] } ) } ), ); ``` ## Errors Fluent AST preserves blocks containing invalid syntax as [`Entry::Junk`]. ## White space At the moment, AST does not preserve white space. In result only a canonical form of the AST is suitable for a round-trip. 48119 9 %
