JS Source Scopes

Build Status codecov

This crate provides functionality for extracting and processing scope information from JavaScript source files, and resolving that scope via SourceMaps.

Features

  • Extracting scopes from source text using extract_scope_names
  • Fast lookup of scopes by byte offset using ScopeIndex
  • Fast conversion between line/column source positions and byte offsets using SourceContext
  • Resolution of minified scope names to their original names using NameResolver
