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

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

let code = r#"
"#;
let mut parser = tree_sitter::Parser::new();
let language = tree_sitter_erlang::LANGUAGE;
parser
    .set_language(&language.into())
    .expect("Error loading Erlang parser");
let tree = parser.parse(code, None).unwrap();
assert!(!tree.root_node().has_error());

Tree Sitter Erlang

This represents tree-sitter grammar used for the Erlang language in the ELP project.

It started as a direct clone of https://github.com/AbstractMachinesLab/tree-sitter-erlang at 7b436e1ca50f0002f6765a9a2a00f6156b2cc881, but was later heavily modified for completeness.

Usage

Install the required toolchain with

make deps

Edit the grammar.js file and re-generate the code with:

make gen

Useful test command, parses foo.erl and opens a browser window to show the process, with pretty pictures of the generated AST.

npm run parse -- --debug-graph testdata/foo.erl
