antlr runtime 3 0 jar is a powerful program library for Windows that includes a library of classes and methods required for generating code such as Parser, Lexer, and Token. It provides a robust framework for working with grammars and parsing input files in various programming languages.
Lexers, parsers, and ASTs
The key advantage of this tool is its ability to produce lexers and parsers in Java, C#, Python, JavaScript, etc. The created components are optimized for high performance and are capable of handling large input items efficiently.
It is important to note that the library allows for construction and manipulation of abstract syntax trees, which represent the parsed input in a structured form. ASTs are useful for a variety of development tasks like analysis and transformation of the code.
Additional functions
The software distribution provides detailed and informative error messages when issues with parsing occur. This feature is essential as it helps you to discover, understand and debug issues with your input files.
Last but not least, the runtime supports both Visitor and Listener patterns, which enable you to traverse and process the ASTs in different ways depending on your specific requirements. To edit code, you may try an application called Atom Text Editor.
Features
- free to download and use;
- compatible with modern Windows versions;
- allows you to parse and process programming code;
- you can build and manipulate abstract syntax trees;
- the tool transforms data into an organized structure.
