Semi-tolerant YAML concrete syntax tree parser.

Usage

let code = "";
match yaml_parser::parse(code) {
    Ok(tree) => println!("{tree:#?}"),
    Err(err) => eprintln!("{err}"),
};

It produces rowan tree if succeeded. For consuming the tree, see rowan's docs.

To build AST from CST:

use rowan::ast::AstNode;
use yaml_parser::{ast::Root, parse};

let code = "";
let tree = parse(code).unwrap();
let ast = Root::cast(tree);
assert!(matches!(ast, Some(Root { .. })));

yaml_parser

Semi-tolerant YAML concrete syntax tree parser.

Usage

match yaml_parser::parse(&code) {
    Ok(tree) => println!("{tree:#?}"),
    Err(err) => eprintln!("{err}"),
};

It produces rowan tree if succeeded. For consuming the tree, see rowan's docs.

If you need to build AST from CST, use ast module:

use rowan::ast::AstNode;

let root = yaml_parser::ast::Root::cast(tree).unwrap();
dbg!(root);
