Finite State Machine C++ Template provides a flexible and a type-safe implementation of finite state machine engine. The main features are type safety, user-provided types for states and events, an explicit description of all the transitions concentrated in one place, the ability to form machine behaviour on-the-fly, and the ability to provide user-defined actions for exceptional situations.
Brace is a dialect of C that looks like Python. It has coroutines, hygenic macros, header generation, and libraries with graphics and sound. It is meant to be good for beginners, kids, and experts. Brace is translated to C, then compiled, with #! support and cached executables. It is fairly portable, and runs on GNU/Linux, Unix, and Windows with MinGW. It should also run on Mac OS X. It comes with a lot of demo programs, many with animated graphics.
The poor man's daily snapshot, glastree builds live backup trees with branches for each day. Users directly browse the past to recover older documents or retrieve lost files. Hard links serve to compress unchanged files, while modified ones are copied verbatim. A prune utility effects a constant, sliding window. It is implemented as a set of Perl scripts.
AML is an implementation of a basic register machine coded in C++. It provides all of the rudimentary features of any machine language like basic I/O and arithmetic but provides a very easy syntax and its own portable binary compression scheme for storing files. AML is currently distributed on SunOS 5.5, Linux 2.2, and Win32 console.
The Functional XML Parsing Framework is a package of low-to-high-level lexing and parsing procedures that can be combined to yield a SAX, DOM, validating parsers, or a parser intended for a particular document type. The procedures in the package can be used separately to tokenize or parse various pieces of XML documents. The package supports XML namespaces, character, internal, and external parsed entities, xml:space, attribute value normalization, processing instructions and CDATA sections. It is intended to be a framework, a set of "Lego blocks" you can use to build a parser that follows DOM, SAX, or another discipline, and performs validation to any degree. As an example of such parser construction, the package includes a semi-validating SXML parser. It converts XML to SXML, an instance of XML Infoset as S-expressions, an abstract syntax tree of an XML document. SXML can be queried (in a XPath style), transformed, and evaluated. The framework parses XML in a pure functional style, as folding over a text XML document considered a spread-out tree. The input port is treated as a linear, read-once parameter. The framework's code does not use assignments at all.
