Antlr Version 4 Examples
-
A parser for Mysql -- This excellent example of the power of Antlr 4 is from the Oracle Workbench library at https://github.com/mysql/mysql-workbench/tree/8.0/library/parsers/grammars, and written by Mike Lischke.
-
Parsing Bison grammars with Antlr. This program parses Bison grammar files using Antlr!
-
Parsing Antlr grammars with Antlr. This program parses Antlr4 grammar files using Antlr.
-
Parsing context-free languages in the Antlr lexer. This program demos the use of the well-known expression grammar in the lexer. The rules can't have left recursion, and they all need to be marked with the fragment keyword, but it works.
-
XPath version 3.1. This C# program contains the latest grammar for XPath, along with 1000+ test cases.
-
Simple arithmetic example targeting C++ using CMake. This program is unique for a CMake configured Antlr C++ program. This is a concrete example of the somewhat incomplete instructions given in the Antlr website.
-
Tomaszewski's example. I was combing the web and came across an interesting article by Tomaszewki, of a CFG grammar that doesn't recognize strings like "ww", but a CFG that recognizes string not in the language--an interesting play on what a recognizer could do.
-
Matlab. This is an example of the Matlab grammar with semantic predicates to correct a tokenization problem with the transpose operator. I've also included the grammar for Octave which I derived by importing the Bison grammar in from the source for Octave.
-
Antlr grammars with C# action blocks. This is an example of parsing an Antlr targeting C# in action blocks.
-
PL1. This is grammar for PL/I that I generated from an import of a Bison grammar for the GNU PL/I front end.
