lib.rs

1//! This crate provides Objectscript language support for the [tree-sitter][] parsing library.
2//!
3//! Typically, you will use the [LANGUAGE_OBJECTSCRIPT_UDL] function 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//! Class Demo.Test
9//! {
10//!   ClassMethod Main()
11//!   {
12//!     set x = 42
13//!   }
14//! }
15//! "#;
16//! let mut parser = tree_sitter::Parser::new();
17//! let language = tree_sitter_objectscript::LANGUAGE_OBJECTSCRIPT_UDL;
18//! parser
19//!     .set_language(&language.into())
20//!     .expect("Error loading Objectscript parser");
21//! let tree = parser.parse(code, None).unwrap();
22//! assert!(!tree.root_node().has_error());
23//! ```
24//!
