Free iso script

SWI-Prolog 5.7.12 is very useful because it offers a comprehensive Free Software Prolog environment, licensed under the Lesser GNU Public License. Together with its graphics toolkit XPCE, its development started in 1987 and has been driven by the needs for real-world applications. These days SWI-Prolog is widely used in research and education as well as for commercial applications.

Major Features:

1. Kernel licensed under the LGPL. Prolog libraries are distributed under the GPL with an additional statement that allows for use in proprietary applications. Details can be found on the license page.
2. fast compilation. E.g., loads 140,000 lines of code spread over 500 source-files in 2.3 seconds on an AMD 5400+ system.
3. Robust and free of memory leaks. In use for several servers that run 24x7.
4. Small. The full development environment, including graphics, libraries and many interface packages requires approx. 40MB harddisk. The non-graphical kernel is about 650Kb, the graphics library adds about 1.2Mb to the image.
5. Scales well for large applications. No limits on program size, atom-length, term-arity or integer values. No performance degradation on predicates with many (indexed) facts.
6. Unbounded integer and rational number arithmetic based on GMP library.
7. Comprehensive set of built-in predicates, covering Part 1 of the ISO standard, the de-facto Edinburgh Prolog standard and important parts of Quintus and SICStus Prolog. Fair compatibility to Ciao, YAP and GNU-Prolog.
8. Flexible and fast interface to the C- and C++-Language. The interface allows for calling both-ways, handling of non-determinism both ways and embedding of the SWI-Prolog kernel in C/C++ projects.
9. The goodies: modules (upward compatible to Quintus and SICStus), garbage-collection (transparent to C/C++-code, including atom garbage collection), last-call optimisation, Dynamic expansion of the runtime stacks, ISO exception-handling (including C/C++ interface for catching and throwing exceptions).
10. Execution profiler (time and call statistics) for Linux, most Unix platforms and Windows NT/2000/XP/Vista.
11. Cross-Referencer. gxref/0 provides a graphical front-end for the extensible Prolog cross-referencer (xref).
12. Portable to many platforms, including almost all Unix/Linux platforms, Windows (NT/2000/XP/Vista, including 64-bit editions), MacOS X (using X11 for graphics) and many more. Both 32-bits and 64-bits hardware is supported. Sources are plain C99, configured automatically using GNU autoconf (configure, make, make install).
13. UNICODE character set handling internal. Ideal for web- and international applications.
14. Machine-independent saved-states (save on one platform, run using the virtual machine of another platform).
15. Multi-threading support: run multiple pre-emptively scheduled prolog engines on the same database.
16. attributed variables, coroutining (freeze/2, when/2, dif/2), global variables, cyclic terms. Flag-controlled handling of occurs-check (on/off/error) see current_prolog_flag/2.
17. Constraint Logic Programming, providing libraries for CHR (Constraint Handling Rules), clp(FD), clp(R,Q) and various others.
18. Bundled with interface libraries for Java (JPL), ODBC, TCP/IP sockets, SSL, CGI form handling, etc.
    
19. Multi-threaded Web server library with comprehensive libraries to generate HTML, HTTP authorization, session management, exchanging JSON (used by many AJAX widgets), etc.
20. Fast and flexible libraries for parsing SGML/XML (HTML), parsing RDF, store and query the RDF triple model. A graphical editor for RDF/RDFS and OWL models called Triple20 is distributed seperately.
21. Literate programming support through PlDoc. Provides integrated view on manual and application documentation and producing LaTeX documentation for your application.
22. Unit testing support through PlUnit.
23. Regular binary distributions for most popular platforms (Windows (32/64 bits), Linux (32 bits) and MacOS X (32 bits)).
24. Regular distribution of the full source packages. The sources are also accesible through GIT.

Chilkat Charset C Library is a powerful tool that can convert text data from one character encoding to another. It works identically on all computers, regardless of locale or internationalization settings.

Supports Unicode, iso-8859-*, windows-*, utf-7, utf-8, utf-16, utf-32, Shift_JIS, gb2312, ks_c_5601-1987, big5, iso-2022-*, euc-jp, euc-kr, x-mac-*, asmo-708, ibm*, dos-*, koi8-*. (Refer to reference documentation for the complete list of supported charsets.)

Major Features:

1. Convert from any supported charset to any other supported charset.
2. Option to drop non-convertable characters.
3. Option to substitute pre-defined bytes for non-convertable characters.
4. Option to substitute hex-escaped string (XXXX) for non-convertable characters.
5. Option to convert to an alternative charset for non-convertable characters.
6. Option to pass through non-convertable characters unchanged.
7. When converting HTML, can automatically update the META tag that specifies the charset.
8. File-to-file conversion.
9. Check for errors in file or in-memory data.
10. Convert charset names to code page numbers, and back.

Requirements:

• - VC++ 8.0

TOAD 0.64.0 is a script featuring a C graphical user interface. It provides some standard features found in other GUI libraries.

Major Features:

1. Model-View Architecture
2. UTF-8 text encoding
3. True color and color dithering on 4 to 8 bit display depths
4. ISO C Template based Signal & Slot style callbacks
5. Signal & Slots is the name of the callback technique in the Qt C GUI library which requires an additional pre-processor while TOAD achieves the same with C templates.
6. Experience shows that keeping track of callbacks in complex applications is too complicated so a new idea is to introduce a central database of callbacks.
7. Closures Well not real closures but closure alike constructs for callbacks. The current implementation uses pre-processor macros but using C templates by provide some advantages in the future.
8. Platform independent font specification via font config (for both X11 and FreeType fonts)
9. Plugable Layout Managers
10. 2D vector graphic editor
11. Postscript, PDF and SVG output (through the Cairo graphics library)
12. high quality UTF-8 text rendering (through Gtks Pango library)
13. Minimal HTML Viewer for Online Documentation
14. The following features are unique:
15. Decoupled Menubar
16. Methods and the menubar/toolbar are connected automatically over the window hierarchy. This not only simplifies the creation of menubars but also allows automatic handling of different menu styles like the single menubar under MacOS X or the typical one menubar per window under X11.
17. Decoupled Undo Management Undo objects and undo-mangers/menu-bars are connected automatically over the window hierarchy.
18. Run-time Layout Editor Layouts of dialogs, menu-bars, form-layouts, etc. can be configured at run-time.

Requirements:

• Binutils 2.9.1 or later
• glibc 2.1 or later
• X Window System Version 11 Release 6 or later
• zlib 1.1.1
• libpng 1.0.1
• Xft
