Synopsis is a multi-language source code introspection tool that provides a variety of representations for the parsed code to enable further processing such as documentation extraction, reverse engineering, and source-to-source translation. It provides a framework of C++ and Python APIs to access these representations and allows Processor objects to be defined and composed into processing pipelines, making this framework very flexible and extensible.
TinyCOBOL is an effort to bring a free COBOL compiler to Linux. It generates GNU assembler for the i386 Linux platform. A executable binary is then created using the GNU assembler and linker. The project is approaching the first beta release with many statements already implemented.
tn5250 is a 5250 terminal emulator, used for connecting to IBM's AS/400 (now known as eServer iSeries) midrange computers. tn5250 implements TN5250E, which means it is capable of device name selection, and printer sessions. The emulator supports color, 132 column mode, and most other features found in 5250 terminals and Client Access' 5250 emulator. While tn5250 is text-based application, a script is included to run it in an xterm properly. If you don't know what an AS/400 is, this program will probably not be of much use to you.
Xbase (formerly known as xdb) is an XBase compatible C++ class library. It provides C and C++ programmers with a cross-platform class and function library for manipulating Xbase type datafiles and indexes. There is support for .DBF and .NDX files (including support for Dbase III and IV memo fields, dates, and record and file locking), and limited support is also supplied for .NTX (clipper index) files. There is also an HTML user interface class which works well with the Apache Web Server.
ZThread is an advanced object-oriented threading and synchronization library, implemented in C++ for POSIX, MacOS, and Win32 systems. It provides an excellent and powerful abstraction from native threads. It includes interruptible thread objects and several other synchronization control objects.
Styx is a scanner/parser generator designed to address some shortcomings of the traditional lex/yacc combination. It has unique features like automatic derivation of depth grammar, production of the derivation tree, including it's C interface, preservation of full source information, pretty printing to faciliate source-source translation, and persistence to aid rapid interpreter writing. It also supports reentrancy. Styx works well under several different OSes, including serveral Unixes, DOS, and Windows.
py-xmlrpc is an extremely fast implementation of the xmlrpc spec for Python (written in C). It supports both blocking and non-blocking clients and servers on Windows and POSIX platforms. Version 0.8.1 is 100% compliant with the xmlrpc validator found at http://validator.xmlrpc.com.
PLplot is a library of C functions that are useful for making scientific plots from programs written in a wide variety of languages. It can be used to create standard x-y plots, semi-log plots, log-log plots, contour plots, 3D plots, shade (gray-scale and color) plots, mesh plots, bar charts, and pie charts. Multiple graphs may be placed on a single page with multiple lines in each graph. Different line styles, widths, and colors are supported. A virtually infinite number of distinct area fill patterns may be used. A variety of output devices and file formats are supported.
