Ragel vs ANTLR

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

Ragel is a Development solution with tags like state-machine, compiler, c, c.

It boasts features such as 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 pros including 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.

On the other hand, ANTLR is a Development product tagged with parsing, code-generation, language-recognition.

Its standout features include 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 it shines with pros like Wide language support, Active community, Easy to learn and use, Good documentation, Flexible and extensible.

Product Overview

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.

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.
