lib.rs

1//! This crate provides HCL language support for the [tree-sitter] parsing library.
2//!
3//! Typically, you will use the [`LANGUAGE`] constant to add this language to a
4//! tree-sitter [`Parser`], and then use the parser to parse some code:
5//!
6//! ```
7//! let code = r#"
8//! example "test" {
9//!   foo = "bar"
10//! }
11//! "#;
12//! let mut parser = tree_sitter::Parser::new();
13//! let language = tree_sitter_hcl::LANGUAGE;
14//! parser
15//!     .set_language(&language.into())
16//!     .expect("Error loading HCL parser");
17//! let tree = parser.parse(code, None).unwrap();
18//! assert!(!tree.root_node().has_error());
19//! ```
20//!
