tree_sitter_powershell/
lib.rs

1//! This crate provides Powershell 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//! "#;
9//! let mut parser = tree_sitter::Parser::new();
10//! let language = tree_sitter_powershell::LANGUAGE;
11//! parser
12//!     .set_language(&language.into())
13//!     .expect("Error loading Powershell parser");
14//! let tree = parser.parse(code, None).unwrap();
15//! assert!(!tree.root_node().has_error());
16//! ```
17//!
