# ANTLR v4 [](http://java.oracle.com) [](https://raw.githubusercontent.com/antlr/antlr4/master/LICENSE.txt) **ANTLR** (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface (or visitor) that makes it easy to respond to the recognition of phrases of interest. **Dev branch build status** [](https://github.com/antlr/antlr4/actions/workflows/hosted.yml) (github actions)
