rome

Rome is a set of Atom/RSS Java utilities that make it easy to work in Java with most syndication formats. Today it accepts all flavors of RSS (0.90, 0.91, 0.92, 0.93, 0.94, 1.0 and 2.0) and Atom 0.3 feeds. Rome includes a set of parsers and generators for the various flavors of feeds, as well as ... [More] converters to convert from one format to another. The parsers can give you back Java objects that are either specific for the format you want to work with, or a generic normalized SyndFeed object that lets you work on with the data without bothering about the underlying format.

javacc

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] standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc. [Less]

The Spirit Parser Library

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] written exclusively in C++. EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable. [Less]

args4j

args4j is a small Java class library that makes it easy to parse command line options/arguments in your CUI application.

Ragel

Ragel compiles finite state machines from regular languages into executable C, C++, Objective-C, D, Java or Ruby code. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language. ... [More] Code embedding is done using inline operators that do not disrupt the regular language syntax. [Less]

Hachoir

Hachoir is a library written in Python which allows to see and edit a binary file (or any binary stream) field per field. A field is the most basic information: a number, a string of characters, a flag (yes/no), etc. Only supported formats can be opened, it's not a magic tool. It can be used to ... [More] extract some information (eg. metadata), edit some fields of a file without the original program, or convert a file from one format to another. [Less]
