PMD scans Java source code and looks for potential problems like:
* Possible bugs - empty try/catch/finally/switch statements
* Dead code - unused local variables, parameters and private methods
* Suboptimal code - wasteful String/StringBuffer usage
* Overcomplicated expressions - unnecessary if statements, for loops
that could be while loops
* Duplicate code - copied/pasted code means copied/pasted bugs
Judy is a general purpose dynamic array implemented as a C callable
library. Judy's speed and memory usage are typically better than other
data storage models and improves with very large data sets.
ASSA is a UNIX/Linux Object-Oriented C++ networking (BSD sockets) library
and application framework based on Adaptive Communication Patterns. ASSA is
designed to improve productivity of writing network-oriented client/server
applications.
Libcfu is a library of tools that may be useful, particularly when
developing multithreaded software. It includes a hash table, a linked list,
self-extending strings, a config file parser, a simple timer, a thread
queue, and command-line parser.
CLAW is a C++ Library Absolutely Wonderful providing useful classes
from the simplest AVL binary search trees to the complex meta
programming tools, including image manipulation, a generic alpha-beta
algorithm, sockets implemented as std::stream and more
Library that provides GLib and Gtk implementation of the DBusMenu protocol.
The DBusMenu protocol make it possible for applications to export and import
their menus over DBus.
Disorder and chaos are interesting phenomena. Calculating the amount
of entropy, information, or disorder in an information stream or data
collection has many interesting applications.
libdisorder provides a simple C library for calculating classic Shannon
entropy (more to come in future releases).
Check is a unit test framework for C. It features a simple interface for
defining unit tests, putting little in the way of the developer. Tests are run
in a separate address space, so Check can catch both assertion failures and code
errors that cause segmentation faults or other signals.
Libcwd is a thread-safe, full-featured debugging support library
for C++ developers. It includes ostream-based debug output with
custom debug channels and devices, powerful memory allocation
debugging support, as well as run-time support for printing source
file:line number information and demangled type names.
A library which may be used to explain Unix and Linux system call
errors. The library is not quite a drop-in replacement for strerror, but
it comes close. Each system call has a dedicated libexplain function.
