Parser Generator

SimpleParse provides a simple and fast parser generator using a modified version of the mxTextTools text-tagging engine. SimpleParse allows you to generate parsers directly from your EBNF grammar. Unlike most parser generators, SimpleParse generates single-pass parsers (there is no distinct... Platforms: BSD Solaris

Bison is a general-purpose parser generator that converts an annotated context-free grammar into an LALR(1) or GLR parser for that grammar. Once you are proficient with Bison, you can use it to develop a wide range of language parsers, from those used in simple desk calculators to complex... Platforms: Mac

Yapps (Yet Another Python Parser System) is an easy to use parser generator that is written in Python and generates Python code. Yapps2 is simple, is easy to use, and produces human-readable parsers. It is not fast, powerful, or particularly flexible. Yapps is designed to be used when regular... Platforms: *nix

BNF for Java project is a parser/generator, or compiler-compiler. The parser reads your input text, or "terminals", specified by your BNF syntax. The parser features indefinate look-ahead and back-track. As the grammar parses your file, it builds a parse-tree which carries the content in the... Platforms: *nix

Rats! is an easily extensible parser generator for C-like languages; though currently it only generates parsers in Java. Rats! project has been explicitly designed so that grammars are concise and easily modifiable. To this end, Rats! - organizes grammars into modules, - builds on parsing... Platforms: *nix

xas is a handy and reliable utility that uses the StringTemplate and a ANTLR parser generator along with a AS grammar in order to translate the input source to one of the target languages. xas is portable and can be run from a command line window. The parser and lexer are C#. Platforms: Windows

A simple way to create a syntax highlighting editor for a custom language/grammar and/or create custom grammar parsers. This is a .NET project written in C#. See details here: http://acct001.com/wordpress/?p=190 Platforms: Windows, Mac, Linux

CB2XML (CopyBook to XML) is a COBOL CopyBook to XML converter written in Java and based on the SableCC parser generator. This project includes utilities to convert an XML instance file into its COBOL copybook equivalent string buffer and vice versa. Platforms: Windows, Mac, Linux

CSharpCC is a compiler-compiler written Java for producing C# parsers from a given grammar. This project is a version of JavaCC (http://javacc.dev.java.net) and accepts a similar grammar, except it supports C# syntax, in spite of Java. Platforms: Windows, Mac, Linux

Hyacc is an efficient and practical Yacc/Bison-compatible full LR(1)/LALR(1)/LR(0) and partial LR(k) parser generator in ANSI C based on Knuth and Pager's LR(1) algorithms. Generated parser can be used in open-source or commercial software. Platforms: Windows, Mac, BSD, Linux

A Java command-line option parser generator, providing function similar to GNU Getopt, but much richer. Platforms: Windows, Mac, Linux

Open source mini Python compiler written in Java using Sablecc as parser generator. Platforms: Windows, Mac, Linux

This project aims to provide a Java-Bytecode compiler for the fairly new programming language WRL and others like PHP4 and Postfix, based on the research on the SableCC parser generator and common W3C.ORG standards. Platforms: Windows, Mac, Linux

Annotation based lexer and parser generator suitable for processing wide range of languages, from small domain specific languages to big ones like Java. Actions may be written directly as annotated java methods. Examples of expression language and Java5. Platforms: Windows, Mac, Linux

SableCC is a parser generator which generates object-oriented frameworks for building compilers, interpreters and other text parsers. SableCC keeps a clean separation between machine and user code which leads to a shorter development cycle. Platforms: Windows, Mac, Linux

Open source and command line based data-driven parser-generator MaltParser is a free and open source system for data-driven dependency parsing, which can be used to induce a parsing model from treebank data and to parse new data using an induced model. MaltParser implements seven deterministic... Platforms: Mac

biplist is a binary plist parser/generator for Python. Platforms: *nix

easyply is a helper library for PLY, parser generator for Python. It acts as a middleware between your grammar definition and PLY. What's so appealing about easyply? PLY supports rather crude parser definitions; easyply adds some EBNF-y flavor to it. easyply is purely a helper in everyday work -... Platforms: *nix

VisualLangLab is a visual parser-generator IDE for development of parsers without code or script of any kind. It is simple in use, and easy to learn. Unlike other parser-generators, VisualLangLab represents parser rules as visual grammar-trees with distinct icons for the grammar-tree nodes. The... Platforms: *nix
