Development

File describing grammar is grammar.js

Every time the grammar file changes code generation needs to be run by invoking npm run gen

npm test command automatically performs code generation

Tests files are located in test/corpus

Here is the documentation on test file syntax

Running tests

npm install --also=dev
npm test
