ParGeL is an LALR(k) parser generator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.
Complete LALR(1) parser generator and engine in PHP.
Complete LALR(1) parser generator and engine (like BISON or YACC) but it's all done in PHP, and the input grammar is easier and more maintainable. Write your actions in PHP. Generate PHP output code. Drive your parser with PHP. Wanna make a language?
Fast Java based PostScript parsing engine. Capable of interpreting PostScript expresions often found in PDF's and outputting results in form of a data array.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
HiLexed 2 is a dynamic hierarchical LL-parser system with integrated lexing. It features a powerful unlimited look-ahead, look-ahead compression*, dynamic rules and left-recursion*. * = Under development
Linear time, dynamic API for lexical analysis and parser generation. Allows for a text-based specification of formal languages with the well-known regular-expressions approach, and using Parsing Expression Grammars as the underlying engine.
A C++ library which enables seamless interoperability between C++ and interpreted languages such as javascript. Based loosely on the boost.python project. A separate javascript parser is supplied.
A runtime parser generator library, generates parsers for context-free grammars.
Parsing scripting languages and communication protocol messages are typical use cases.
The library is written in straight C++ and requires STL.
Clean, correct, efficient.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.

Expression4J (Math Expression Parser) is a java framework used to manage mathematic expression stored in String object like "f(x,b)=2*x-cos(b)" or "g(x,y)=f(y,x)*-2". Expression gramar can be define by user (add new operator or type ...)
Tedir is a general purpose top-down parser library for java. Unlike a parser generator, it allows efficient parsers to be constructed at run-time, rather than at compile-time, and allows parsers to be extended while running.
Pure Python implementation of GOLD Parser Engine.
GOLD Parser Engine is a LALR(1) parser with DFA tokenizer.
It uses compiled grammar table generated by GOLD Parser Builder (not included - available on http://www.devincook.com/goldparser)
An extensible Java implementation of the W3C XQuery language. The project aims to provide
a generic XQuery parser (written with JavaCC),
translation to the XQuery core grammar,
modularised query optimisation,
and an open XMLSchema type system.
Native Java parser framework, no (pre-)compilers needed. Closely follows BNF syntax. Optimized for performance and low overhead. Highly flexible and extendable using a streamlined API. Integrate semantics, tracing and even context sensitive parsers.
JEPLite is a light-weighted (re)implementation of the Java Expression Parser (jep.sourceforge.net). The intention is to strip some of its not-so-often-used features, and thus speeding the rest. Includes expression optimizer.
The program emulates a MIX machine (introduced by Knuth in his books "The Art of Computer Programming").
- MIX Assembly Language (MIXAL) parser that converts the MIXAL code to MIX machine code
- a MIX interpreter which executes MIX machine code
DAVIS is an easy and useful language for IRC bots. This project contains our own bots, some bots for demonstration, a parser that creates Java, C, Perl and IRC-Script code out of a DAVIS file, and an interpreter for DAVIS files.
YooParse stands for Yet-another Object-Oriented Parser code generator. It is the complement of YooLex, a lexer code generator. The purpose of YooParse is to generate a parser that integrates tightly with the scanner generated by YooLex.
HotSAX is a fast, small footprint, non-validating SAX2 parser for HTML/XML/XHTML. It can be used in simple web agents, page scrapers and spiders. The goal is to embed this in cell phone "midlets."
XPath Parser is a library consisting of parser for XPath-expressions and a set of classes which are used to represent their structure. Parser creates class-based structure of an XPath expression which may be manipulated as required.
This small library ma
