ANTLR vs Ragel

Struggling to choose between ANTLR and Ragel? Both products offer unique advantages, making it a tough decision.

ANTLR is a Development solution with tags like parsing, code-generation, language-recognition.

It boasts features such as Generates lexical analyzers and parsers from grammar descriptions, Supports multiple target languages like Java, C#, Python, JavaScript, Go, C++, Swift, Generates parse trees/ASTs for parsed input, Performs syntax validation and error reporting, Built-in runtime library for tree parsing/walking and pros including Wide language support, Active community, Easy to learn and use, Good documentation, Flexible and extensible.

On the other hand, Ragel is a Development product tagged with state-machine, compiler, c, c.

Its standout features include Compiles state machines defined using a DSL to C/C++ code, Supports finite state machines, lexical analyzers, pattern matchers, Performs optimizations like state collapsing and table compression, Integrates with common build systems like Make, Autoconf, etc., and it shines with pros like Clean and compact DSL for defining state machines, Fast execution of generated state machines at runtime, Good for tasks like lexing, parsing, protocol handling, Actively maintained and open source.

Product Overview

ANTLR

Description: ANTLR (ANother Tool for Language Recognition) is an open source parser generator for reading, processing, executing, or translating structured text or binary files. It's useful for building languages, tools, and frameworks.

Ragel

Description: Ragel is a state machine compiler that lets developers write state machines using a compact syntax. It can then generate C or C++ code to execute the state machines efficiently at runtime.
