Support StringTemplate, ANTLR Project by making a donation! Terence often pays for things like the antlr.org server, conference travel, and this site design (that alone cost US$1000). Buy him a beer and pizza remotely ;)

Currently available with C, C++, Objective-C, Ruby, C#, ActionScript, JavaScript, and Java targets; other targets under development.

ANTLRWorks+ANTLR

ANTLRWorks is a GUI development environment for building ANTLR v3 grammars. It is a stand-alone Java application that you can just click on to start using ANTLR. It contains all necessary jars and is the easiest way to get started using ANTLR. 1.5.1 is the latest stable release and contains ANTLR v3.5.1.



Note: ANTLRWorks requires Java 1.5 or later to run

On Mac OS X you can just click on that jar and it will start up the GUI. Same for Windows unless you use IE (IE thinks it's a zip so you'll have to rename it). On Linux, you have to save to the disk and run from the command line. That jar includes all the other jars necessary to run it including ANTLR 3.5.2, StringTemplate 4.0.8, and StringTemplate 3.2.1.

ANTLR v3

Latest ANTLR version is 3.5.2, released March 25, 2014. v3 is written in ANTLR v3 and StringTemplate 4.0.8. Parsers that build template output still use StringTemplate v3 for backward compatibility. In antlr-3.5.2-complete.jar, you'll find everything you need to make ANTLR and its generated parsers work. Please see release info.

Previous Versions

Take your pick from download directory.

ANTLR Tool Binaries

ANTLR v3.1.x binaries for .NET framework. No dependence on the Java runtime. antlr3.exe and StringTemplate and ANTLR runtime libraries it depends on. Completely independent version written by Sam Harwell (ported from Java).

Useful add-ons

gUnit grammar unit testing

Leon Su has created an awesome unit testing system for grammars called gUnit (included in main distribution as of 3.1 release). It provides a simple way to write and run automated tests for grammars in a manner similar to what jUnit does for unit testing. The basic idea is to come up with a bunch of input/output pairs for rules in a grammar. The input can be a single line or multiple lines of strings or even an external file. The output can be simply success or failure, an abstract syntax tree (AST), a rule return value, or some text output.

gUnitEditor: Thanks to Shaoting Cai, we have a GUI for gUnit! You can download gUnitEditor here.

Eclipse Plug-ins

  1. Edgar Espina (same name at gmail.com) has created a cool looking ANTLR v3 plugin for eclipse.

  2. AntlrDT: Antlr v3.1 grammar and StringTemplate editors to the Eclipse platform.
    • AntlrDT Editor and Outline View; syntax-assisted editor AntlrDT Builder
    • incremental Lexer/Parser generator
    • StringTemplate Editor; syntax-assisted editor

NetBeans plugin

ANTLR Support for netbeans. Or, from the NetBeans repository.

Visual Studio Modules

Sam Harwell's Visual Studio module for ANTLR. Also does StringTemplate syntax highlighting.

Tech Support

Technical support is available monthly or in chunks of 6 months from the project lead, Terence Parr. For the duration, you can ask Terence direct questions via a special support mailing address. Contact is email-only and replies are sent within one business day, often within hours. This support consists of answering questions and providing advice, not building grammars or other software. Note: Terence is only able to answer questions related to the Java target. The following buttons take you to paypal:

Examples

ANTLR v3 sample grammars (C, C#, Java, ActionScript, and Python targets).

Also, see code samples from Language Implementation Patterns

Mantra Programming Language for a prototype (work in progress).

ANTLR v2

Previous generation is ANTLR version 2.7.7 (released November 1, 2006).

Here is an ANTLR v2 to v3 converter (in progress and only marginally useful; send me fixes!).

ANTLR v2 downloads

ANTLR comes with complete source and is released under the BSD license.

Please see getting started.

Terence Parr, the ANTLR project leader, is available for tech support.
