formatter/index.js:2

• [nitpick] Consider renaming 'init1' to a more descriptive identifier (e.g., 'initQlue') to improve code clarity.

import init1, { format_raw, determine_operation_type } from 'qlue-ls';

formatter/index.js:20

• [nitpick] Consider renaming 'init2' to a more descriptive identifier (e.g., 'initSparqlParser') to clearly distinguish it from other module initializations.

import init2, { get_parse_tree } from 'll-sparql-parser';
