The Lemon program is an LALR(1) parser generator. It takes a context free grammar and converts it into a subroutine that will parse a file using that grammar. Lemon is similar to much more famous programs Yacc and Bison. But lemon is not compatible with either of them; there are several important differences: - Lemon using a different grammar syntax which is less prone to programming errors - Lemon generates a parser that is faster than Yacc or Bison parsers (according to the author) - The parser generated by Lemon is both re-entrant and thread-safe - Lemon includes the concept of a non-terminal destructor, which makes it much easier to write a parser that does not leak memory

Cello is a library that introduces higher level programming to C. Interfaces allow for structured design Duck Typing allows for generic functions Exceptions control error handling Constructors/Destructors aid memory management Syntactic Sugar increases readability C Library means excellent performance and integration

libIDL is a library for creating trees of CORBA Interface Definition Language (IDL) files, which is a specification for defining portable interfaces. libIDL was initially written for ORBit (the ORB from the GNOME project, and the primary means of libIDL distribution). However, the functionality was designed to be as reusable and portable as possible.

This library implements the Code Sourcery C++ ABI, as documented here: It is intended to sit below an STL implementation, and provide features required by the compiler for implementation of the C++ language.

libdap is A C++ SDK which contains an implementation of DAP 2.0 and 3.1, Client- and Server-side support classes and a prototype implementation of the AIS. OpeNDAP's public key is available at http://opendap.org/download/index.html#public_key

This is an implementation of double-array structure for representing trie, as proposed by Junichi Aoe. Trie is a kind of digital search tree, an efficient indexing method with O(1) time complexity for searching. Comparably as efficient as hashing, trie also provides flexibility on incremental matching and key spelling manipulation. This makes it ideal for lexical analyzers, as well as spelling dictionaries.

ANTLR, ANother Tool for Language Recognition, is a language tool that provides a framework for constructing recognizers, interpreters, compilers, and translators from grammatical descriptions containing actions in a variety of target languages. ANTLR provides excellent support for tree construction, tree walking, translation, error recovery, and error reporting. This package provides the ANTLR v3 C runtime library.

libarena is a custom memory allocator interface and implementation. Four allocators are provided: flat LIFO arena allocator, object pool allocator and two malloc(3) wrappers: one which returns the pointers unadulterated and one which obeys the requested, arbitrary alignment. These can be used directly, or through their exported prototype interfaces. libarena is meant to provide a baseline interface so allocators can be stacked, and to provide a simple and well defined interface for libraries and applications without becoming mired in features or capabilities. It is not meant to restrict or confine what custom allocators can actually accomplish. For instance, the included pool and arena allocators include a suite of string utilities which aren't available in the generic exportable interface. Note that these string utilities are built upon a generic interface (see util.h) which can take the prototypical allocation context, so they are also available to any 3rd party compatible allocators.

Click is a Python package for creating beautiful command line interfaces in a composable way with as little code as necessary. It's the "Command Line Interface Creation Kit". It's highly configurable but comes with sensible defaults out of the box.
