Tree-sitter Grammar for Erlang

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
