This crate provides dockerfile language support for the tree-sitter parsing library.

Typically, you will use the language function to add this language to a tree-sitter Parser, and then use the parser to parse some code:

let code = "";
let mut parser = tree_sitter::Parser::new();
parser.set_language(tree_sitter_dockerfile::language()).expect("Error loading dockerfile grammar");
let tree = parser.parse(code, None).unwrap();

tree-sitter-dockerfile

Dockerfile grammar for tree-sitter.
