What is ANTLR Parser Generator?

✍: FYIcenter


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 and walk parse trees.

ANTLR takes as input a grammar that specifies a language and generates as output source code for a recognizer for that language. While version 3 supported generating code in the programming languages Ada95, ActionScript, C, C#, Java, JavaScript, Objective-C, Perl, Python, Ruby, and Standard ML, the current release at present only targets Java, C#, C++, JavaScript, Python2, Python3, Swift, and Go. A language is specified using a context-free grammar which is expressed using Extended Backus–Naur Form (EBNF).[citation needed]

The latest version of ANTLR is provided in 3 packages:

  • Complete ANTLR 4.10.1 Java binaries jar - Complete ANTLR 4.10.1 tool, Java runtime and ST 4.0.8, which lets you run the tool and the generated code.
  • ANTLR 4.10.1 distribution (zip) - Everything you need to build the tool and Java runtime from source.
  • ANTLR 4.10.1 Java runtime binaries jar - Only what's needed for building and executing parsers/lexers generated in Java.
