//! This crate provides vimdoc language support for the [tree-sitter][] parsing library.
//!
//! Typically, you will use the [language][language func] function to add this language to a
//! tree-sitter [Parser][], and then use the parser to parse some code:
//!
//! ```
//! let code = r#"
//! {lines} |readfile()|-style
//! {type} behavior:
//! • "b" |blockwise-visual|
//! • "c" |charwise|
//! • "l" |linewise|
//! • "listitem"
//! {consumes} adjacent
//! "#;
//! let mut parser = tree_sitter::Parser::new();
//! parser.set_language(&tree_sitter_vimdoc::language()).expect("Error loading vimdoc grammar");
//! let tree = parser.parse(code, None).unwrap();
//! ```
//!
