ANother Tool for Language Recognition (ANTLR) is the name of a parser generator that uses LL(k) parsing. ANTLR is the successor to the Purdue Compiler Construction Tool Set (PCCTS), first developed in 1989, and is under active development. Its maintainer is professor Terence Parr of the University of San Francisco.
NLTK — the Natural Language Toolkit — is a suite of open source Python modules, linguistic data and documentation for research and development in natural language processing, supporting dozens of NLP tasks, with distributions for Windows, Mac OSX and Linux.
Java Compiler Compiler is the most popular parser generator for use with Java applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other ... [More]
Spirit is an object-oriented, recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow Spirit to approximate the syntax of Extended Backus Normal Form (EBNF) completely in C++. The Spirit framework enables a target grammar to be ... [More]
Happy is a parser generator system for Haskell, similar to the tool `yacc' for C. Like `yacc', it takes a file containing an annotated BNF specification of a grammar and produces a Haskell module containing a parser for the grammar. Happy is flexible: you can have several Happy parsers ... [More]
BESEN is an acronym for "Bero's EcmaScript Engine", and it is a complete ECMAScript Fifth Edition Implemention in Object Pascal, which is compilable with Delphi >=7 and FreePascal >= 2.5.1 (2.4.0 only inoffically). BESEN is licensed under the LGPL license with ... [More]
Stratego/XT is a language and toolset for program transformation. The Stratego language provides rewrite rules for expressing basic transformations, programmable rewriting strategies for controlling the application of rules, concrete syntax for expressing the patterns of rules in the syntax of ...

Irony is a development kit for implementing languages on .NET platform. Unlike most existing yacc/lex-style solutions Irony does not employ any scanner or parser code generation from grammar specifications written in a specialized meta-language. In Irony the target language grammar is coded directly ... [More]
SableCC is an object-oriented framework that generates compilers (and interpreters) in the Java programming language.
L is a general-purpose, compiled, extensible programming language. Extensions appear at three different levels: the syntax is completely replacable; Lisp-like macros allows for creation of new construct in the language; new global definitions enable to change the paradigm of the language. The ... [More]
