mtCellEdit is a lightweight spreadsheet program. Its main goal is to provide facilities for simple day-to-day tasks using a minimal graphical user interface. It uses TSV based file formats to ensure that archived data is always accessible to other programs, regardless of operating system, both now and in the future. These "other programs" might be spreadsheet programs, text editors, command line tools, or custom built programs. It is written from scratch and provides all of its core facilities via a library, so any C program can access its API.
The OODBMS/DBMS ODABA is an terminology-oriented database management system (TODBMS) on a high conceptual level. This is an extension of the ODBMS concept according to ODMG 3. It provides a number of enhanced features based on natural language analysis. Beside the database kernel, a number of tools are provided for database design, documentation, and fast development. ODABA provides a powerful interface (C++, .NET) and an ODABA Script Interface (OSI), a C++/JAVA like scripting language, which provides easy access to the database.
LibAPCNIS is a PHP library for accessing the NIS port of the Apcupsd UPS Monitoring daemon. It allows you to access realtime UPS stats from a PHP script without having Apcupsd installed. It does not require the apcaccess application included with an Apcupsd installation, and there are no external dependencies.
UverseWiki is a modular open source PHP framework designed for text processing. Unlike most existing solutions, it is not regular expression-based but instead uses a recursive descent parser to build a document object model. After the parsing stage has been finished and the DOM is produced, the original source is discarded and all operations are performed on the document tree instead: nodes can be altered, serialized, or rendered into a particular format (such as HTML or RTF). The wiki syntax is language-neutral and the processing itself is carried out in UTF-8.
libdwarf is a library and command line tool for manipulating DWARF data in ELF object files. The DWARF Debugging Information Format is of interest to programmers working on compilers and debuggers. All libdwarf distributions contain C source, the DWARF2 specification, and libdwarf specifications. Implementors often extend DWARF by adding new attributes and other things.
