EBNF Grammar to AST Parser

The `ebnf` package provides a JavaScript and TypeScript-compatible library for generating Abstract Syntax Tree (AST) parsers from formal grammars defined in either Backus-Naur Form (BNF) or W3C Extended Backus-Naur Form (EBNF). It is currently at version 1.9.1. The library differentiates itself by offering direct AST generation, browser compatibility, and built-in TypeScript type definitions, making it suitable for both Node.js and client-side applications. Releases appear to be driven by bug fixes and minor improvements, without a strict time-based cadence. It's particularly useful for projects requiring custom language parsing or syntax highlighting, such as Domain Specific Languages (DSLs) or code analysis tools.
