Assoc-Right ANTLR - C++

Assoc-Right ANTLR is a C++ library that provides a way to easily generate parsers and lexers using ANTLR. ANTLR, or ANother Tool for Language Recognition, is a powerful parser generator that can be used to create parsers and lexers for a wide range of programming languages and file formats.

Features

• Easy to use: Assoc-Right ANTLR makes it easy to generate parsers and lexers for your code. You don't need to be an expert in compilers or parsers to use it.
• Powerful: ANTLR is a powerful parser generator that can handle complex grammars and produce high-quality parsers and lexers.
• Customizable: Assoc-Right ANTLR allows you to customize your parsers and lexers to suit your needs. You can specify your own error-handling routines, define your own actions, and more.
• Cross-platform: Assoc-Right ANTLR works on Windows, macOS, and Linux, and is compatible with a wide range of compilers and development environments.

Installation

To use Assoc-Right ANTLR in your C++ project, you will need to download and install ANTLR. You can download ANTLR from the ANTLR website: https://www.antlr.org/

After you have installed ANTLR, you can install Assoc-Right ANTLR by downloading the source code from the Github repository: https://github.com/danfickle/assoc-right-antlr-cpp

Once you have downloaded the source code, you can build and install Assoc-Right ANTLR by following the instructions in the README file.

Example

Here is an example of how to use Assoc-Right ANTLR to generate a parser and lexer for a simple programming language:

#include <iostream>
#include "antlr4-runtime.h"

#include "MyLexer.h"
#include "MyParser.h"

int main(int argc, const char* argv[]) {

    antlr4::ANTLRInputStream input("(2 + 2 * 3) / 3");
    MyLexer lexer(&input);
    antlr4::CommonTokenStream tokens(&lexer);

    MyParser parser(&tokens);
    auto tree = parser.expr();

    std::cout << tree->toStringTree(&parser) << std::endl;

    return 0;
}

In this example, we use ANTLR to generate a lexer and parser for a simple expression language. We then parse the expression "(2 + 2 * 3) / 3" using the generated lexer and parser, and print out the resulting parse tree.

Conclusion

If you need to parse and analyze code in your C++ projects, Assoc-Right ANTLR is a powerful and easy-to-use tool that can help you. With its support for ANTLR, it can handle complex grammars and produce high-quality parsers and lexers. Give it a try in your next project!
