Ctalk adds classes, methods, operator overloading, inheritance, and complex object expressions to otherwise standard C programs. Programs can use only a few Ctalk objects and methods in an otherwise standard C program, but the language can be used to write entire programs also. Ctalk works on most if not all of the systems that support GCC, the GNU C compiler. The package includes the language, class and run-time libraries, example programs, tutorial, and language reference.
Gearmand is the job server component of Gearman. Gearman provides a generic framework to farm out work to other machines, dispatching function calls to machines that are better suited to do work, to do work in parallel, to balance the load of processing, or to call functions between languages.
libtld is a library used to extract the TLD from a URI and to check email validity. This allows you to extract the exact domain name, sub-domains, and all the TLD (top level, second level, third level, etc.). The problem with TLDs is that you cannot know where the domain starts. Some domains can use one top-level domain, others use two, etc. However, it may be useful to know where the domain is to have the exact list of sub-domains. For example, if you want to force www. at the start of the domain name if no other sub-domains are specified, then you need to know exactly how many TLD are defined in a URI. The libtld offers one main function: tld(), which gives you a way to extract the TLD from any URI. The result is the offset where the TLD starts. This gives you enough information to extract everything else you need. For emails, the library is capable of parsing a string that represents a list of email addresses to be verified. The verification includes a check of the domain name and its TLD.
Wslay is a WebSocket library written in C. It implements the protocol version 13 described in RFC 6455. This library offers 2 levels of API: an event-based API and a frame-based low-level API. For the event-based API, it is suitable for non-blocking reactor pattern style. You can set callbacks in various events. For the frame-based API, you can send WebSocket frame directly. Wslay only supports the data transfer part of the WebSocket protocol and does not perform the opening handshake in HTTP. It does not perform any I/O operations for its own. Instead, it offers callbacks for them. This makes Wslay independent of any I/O frameworks, SSL, sockets, etc. It is portable across various platforms, and the application authors can choose I/O frameworks freely.
fpgatools is a toolchain for programming flexible programmable gate arrays (FPGAs). The only supported chip at this time is the xc6slx9, a cheap (circa $10 U.S.) but powerful 45nm-generation chip with about 2400 LUTs, block ram, and multiply-accumulate devices. The principles of fpgatools are to reach the maximum physical performance of the chip, to provide fast development cycles, to be an independent toolchain which only depends on other Free Software, and to be a lightweight C implementation without a GUI.
s6-dns is a small, efficient, complete, and IPv6-ready DNS client library, with synchronous as well as asynchronous APIs. It is designed to replace libresolv in projects that need to perform DNS resolution. It also comes with small command-line utilities to make common and not so common DNS queries.
