Application Kit The Application Kit defines a set of Objective-C classes and protocols, C functions, and assorted constants and data types that are used by virtually every NeXTSTEP application. The pith of the Kit are the tools it provides for implementing a graphical, event-driven user interface: The Application Kit provides classes---most notably Window and View---that make drawing on the screen exquisitely succinct. Much of the unromantic work that's involved in drawing---communicating with hardware devices and screen buffers, clearing areas of the screen before drawing, coordinating overlapping drawing areas---is taken care of for you, letting you concentrate on the much more gratifying task of supplying code that simply draws. And even this task is assisted by many of the other classes and a number of C functions that provide drawing code for you. The Application Kit makes event handling extremely simple. The Responder class, from which many of the Kit's classes inherit, defines a mechanism by which the user's actions are passed to the objects in your application that can best respond to them. The Application class, which inherits from Responder, establishes the low-level connections that makes this system possible. It provides methods that inform your application of watershed events, such as when the user makes the application active and inactive, and when the user logs out or turns off the computer. By using these tools, you bless your application with a look and feel that's similar to other applications, making it easier for the user to recognize and use.

Database Kit The Database Kit provides a comprehensive set of tools, classes, and protocols for building applications that use a high-level entity-relationship model to manipulate database servers such as those provided by Oracle or Sybase. The kit provides services that include: Communication with client-server databases. Modeling properties (attributes and relationships) of each database. Record management and buffering. Data flow between record managers and the application user interface. User interface objects for display and editing. (Introduction from the NeXTSTEP General Reference, "Database Kit" reprinted with permission. Copyright (c) 1993 NeXT Computer, Inc. All rights reserved.) Distributed Objects The Distributed Objects system provides a relatively simple way for applications to communicate with one another by allowing them to share Objective-C objects, even amongst applications running on different machines across a network. They are useful for implementing client-server and cooperative applications. The Distributed Objects system subsumes the network aspects of typical remote procedure call (RPC) programming, and allow an application to send messages to remote objects using ordinary Objective-C syntax. The Distributed Objects system takes the form of two classes, NXConnection and NXProxy. NXConnection objects are primarily bookkeepers that manage resources passed between applications. NXProxy objects are local objects that represent remote objects. When a remote object is passed to your application, it is passed in the form of a proxy that stands in for the remote object; messages to the proxy are forwarded to the remote object, so for most intents and purposes the proxy can be treated as though it were the object itself. Note that direct access to instance variables of the remote object isn't available through the proxy.

Indexing Kit The Indexing Kit is a set of programmatic tools for managing data, especially the large amounts of data characteristic of information intensive applications. Much as the Application Kit provides a framework for a graphical interface, the Indexing Kit provides a framework for data management. The Indexing Kit supplies facilities for building custom databases and for searching the UNIX file system. Key benefits include guaranteed data integrity, excellent performance, thread-safe operation, tight integration with the NeXTSTEP programming environment, and the ability to efficiently store and retrieve Objective-C objects and unstructured data like text, sound, and images. The Indexing Kit consists of: A transaction-oriented foundation for storing and retrieving persistent data, using virtual memory mapping for efficient random access to parts of a file without reading or writing the entire file. Transactions guarantee data integrity on persistent storage media, and are also used to manage concurrent access to shared data. Fast sequential and associative access to stored data. Associative access is untyped, in that the programmer defines the data types of keys and their ordering by means of a comparison function or a format string. A simple data management capability based on the Objective-C run-time system. Records can be moved efficiently between working memory and the storage substrate in the form of Objective-C objects. Multiple indexes can be built over programmer-defined attributes, so that records can be ordered and retrieved by the values of their indexed attributes. A general query processing facility, including a declarative query language and its interpreter. Queries can be applied to individual objects, to collections of objects, or to the attribute/value lists produced by Indexing Kit's customizable text processing tools. High-level file system searching facilities based on the supporting layers described above, including fast literal searching of file contents. (Introduction from the NeXTSTEP General Reference, "Indexing Kit" reprinted with permission. Copyright (c) 1993 NeXT Computer, Inc. All rights reserved.) Mach Kit The Mach Kit provides an object-oriented interface to some of the features of the Mach operating system. At this time, it is most useful to applications that make use of the Distributed Objects system, since these applications rely upon Mach's message sending abilities to transport objects, ports, and data between processes. The Mach Kit may also be useful for drivers and multi threaded applications. The Mach Kit provides several classes and protocols, listed below. (Introduction from the NeXTSTEP General Reference, "Mach Kit" reprinted with permission. Copyright (c) 1993 NeXT Computer, Inc. All rights reserved.) NetInfo Kit The NetInfo Kit is a collection of classes and a single function used to provide a connection to and interface with NetInfo domains. The NetInfo Kit provides classes for basic interface with a domain as well as specialized panels. (Introduction from the NeXTSTEP General Reference, "NetInfo Kit" reprinted with permission. Copyright (c) 1993 NeXT Computer, Inc. All rights reserved.) 3D Kit The 3D Graphics Kit enables NeXTSTEP applications to model and render 3-dimensional scenes. Much as the Application Kit's 2D graphics capabilities are based on the Display PostScript interpreter, the 3D Kit's capabilities are based on the Interactive RenderMan renderer. There are both similarities and differences in the inner workings of the two implementations. One similarity is that both are implemented with a client-server model, in which client applications send drawing code to the Window Server, which does the actual drawing. Another similarity is that N3DCamera---the 3D Kit's View---generates all drawing code, both 2D and 3D, when its drawSelf: method is invoked. This keeps the Application Kit's display mechanism intact for both PostScript and RenderMan drawing. One difference in the implementations is in the code generated for drawing. For 2D drawing, a View sends PostScript code to the Window Server's Display PostScript interpreter. For 3D drawing, a View sends RenderMan Interface Bytestream (RIB) code to the Window Server's Interactive RenderMan renderer. (Introduction from the NeXTSTEP General Reference, "3D Graphics Kit" reprinted with permission. Copyright (c) 1993 NeXT Computer, Inc. All rights reserved.) Sound Kit The Sound Kit is designed to provide both low- and high-level access to sound hardware on workstations running NeXTSTEP, including support for a wide variety of sound formats, real-time mixing and compression. The Sound Kit consists of five general categories of objects: Sound Device Objects Sound Device objects, like NXSoundIn and NXSoundOut, wrap the low-level hardware and sound drivers into simple, extensible packages. Sound Streams Sound Stream objects, like NXPlayStream or NXRecordStream, allow the sound output of many simultaneous programs to be mixed, scaled, and processed before being sent out the Sound objects. The Sound Object The Sound object is NeXTSTEP's fundamental sound data storage and playback/recording facility. The SoundView Object NeXTSTEP's Sound View is a graphical display of sound data that interacts well with the NeXTSTEP GUI. The Sound Meter Object The Sound Meter displays the current running amplitude of a playing or recording sound (in mono), much like volume meters on amplifiers or tape decks. In addition to this library, NeXT provides two sets of sound driver and sound access functions. NXLiveVideoView The NXLiveVideoView class provides API for interactive display of live video on the screen of a NeXTdimension Computer. The NXLiveVideoView class specification provides a complete discussion of the NeXTdimension Computer's video capabilities and the API provided by NXLiveVideoView. (Introduction from the NeXTSTEP General Reference, "Video" reprinted with permission. Copyright (c) 1993 NeXT Computer, Inc. All rights reserved.) Applications There are several classes which solely exist to enable the programmer to add functionality to specific existing NEXTSTEP applications: IBPalette, IBInspector These classes allow developers to expand the functionality of the Interface Builder application, creating their own palettes of objects that can be dragged into an interface, and inspectors to set and view the attributes of those objects. Layout This class allows developers to add their own modules to the Preferences application. WMInspector This class allows developers to add their own file contents inspectors to the Workspace Manager application. Portable Distributed Objects (PDO) PDO makes it possible to deploy server-based objects on non-NEXTSTEP server machines. PDO provides this framework by extending the same seamless object framework that NEXTSTEP developers already use for local and distributed objects. Enterprise Objects Framework (EOF) Enterprise Objects Framework seamlessly extends the power of NEXTSTEP's object-oriented paradigm to the development of client-server database applications. Other Before NeXTSTEP 3.0, MusicKit was distributed as part of NEXTSTEP. MusicKit is now maintained and made available by CCRMA (see the entry under `Public Domain Kits'). Also until the advent of NeXTSTEP 3.0, PhoneKit was part of NeXTSTEP. PhoneKit classes provided easy to ISDN connections.

GNU Objective-C Class Library The GNU Objective C Class Library, version 0.1.19, is now available. What is the GNU Objective C Class Library? ========================================== It is a library of general-purpose, non-graphical Objective C objects designed in the Smalltalk tradition. It includes collection objects for maintaining groups of objects and C types, streams for I/O to various destinations, coders for formating objects and C types to streams, ports for network packet transmission, distributed objects (remote object messaging), pseudo-random number generators, string handling, and time handling facilities. Noteworthy changes since version `0.1.10' ========================================= * Now using `src', `config' and `doc' directories to un-clutter the top-level directory. * New GNUStep classes implemented: NSDictionary, NSMutableDictionary; concrete classes NSGDictionary, NSGMutableDictionary; enumeration classes NSGDictionaryKeyEnumerator, NSGDictionaryObjectEnumerator. * More methods in NSData are implemented, thanks to Albin Jones. * More methods in NSString are implemented; we have new classes NSCharacterSet and NSBitmapCharSet; all thanks to Adam Fedor. * And several bug fixes. See the ChangeLog for details. Where can you get it? How can you compile it? ============================================== The library requires gcc 2.7.0 or higher. The library does not work with the NEXTSTEP 3.2 compiler because that version of NeXT's cc cannot handle nested functions. Until a later release from NeXT, NEXTSTEP users will have to install gcc. See the `INSTALL' file for more instructions about compiling and installing the library. The library has been successfully compiled and tested with the following configurations: mips-sgi-irix5.2 Some previous snapshots of the library worked with these configurations, but they haven't been tested recently (We are looking for a volunteer to write a test suite using dejagnu): sparc-sun-sunos4.1.3, m68k-next-nextstep3.0, rs6000-ibm-aix3.2, sparc-sun-solaris2.3, i386-unknown-linux, i386-sun-solaris2.4, i386-unknown-sysv4.0, Ultrix 4.2, HP/UX 9.01. It is known not to work with: alpha-dec-osf The `.tar' file is compressed with GNU gzip. Gzip can be obtained by anonymous ftp at any of the GNU archive sites. For info about FTP via email, send email to `ftpmail@decwrl.dec.com' with no subject line, and two-line body with line one `help' and line two `quit'. The most recent (not necessarily tested) snapshots of the library will be placed in `ftp://alpha.gnu.ai.mit.edu/gnu'. Contact R.

BarCodeKit allows both developers and organizations to quickly add bar coding to custom NEXTSTEP applications. By combining the power of object orientation and PostScript into a comprehensive library of bar code symbologies, BarCodeKit represents the state of the art in bar code technology. Developers can seamlessly add bar coding to an existing application in a matter of minutes by using any of the 35 pretested and reusable objects in the BarCodeKit library of palettes. Previously, adding bar coding to an application meant weeks or months of development, incompatibility with different bar code readers and the use of costly proprietary bar code printers. The BarCodeKit features a full range of bar code symbologies including Code 3 of 9, Code 39 Extended, UPC-A, UPC-E, HRI, NDC, EAN-8, EAN-13, JAN-8, JAN-13, ISBN, ISSN, SICI, SISAC, POSTNET, ABC, FIM, BRM, Interleaved Two of Five, MSI, Codabar, Code 11, Code 93, Code 128, Code 16K and Code 49. It complies to international, national, military and commercial bar coding standards including EAN, JAN, CEN, ANSI, MIL, USS and HIBCC. Furthermore, it provides developers with flexibility; bar codes created using the kit can be scaled and rotated to fit a specific area on a label or document and saved in EPS, EPSI (EPS with interchange bitmap preview for non Display PostScript computers), or TIFF formats. BarCodeKit is an excellent complement to NEXTSTEP's Application Kit and Database Kit It was nominated for a Best of Breed Award by the editors of NeXTWORLD Magazine. SERIALPORTKIT SerialPortKit is a fundamental class library and palette that makes communication with serial peripherals easy to add into your custom NEXTSTEP applications without any of the drawbacks of other solutions. You can use SerialPortKit to communicate with a variety of serial peripherals such as modems, printers, terminals, audio/video equipment, bar code readers, magnetic stripe readers, controllers and data acquisition devices. The SerialPortKit contains a single SerialPort class which interfaces to our SerialPortServer. Additional classes for specific peripherals are available in our SerialPeripheralsKit or through our consulting service. You can easily incorporate the SerialPortKit into your custom applications due to its professionally designed and truly object-oriented programming interface. The included Interface Builder palette, source code examples, on-line indexed reference manuals and tutorial further removes the tedious task of traditional serial port programming.

Suite's DOME is a complete distributed object-oriented architecture with class libraries, application development tools and run-time environment. With DOME, systems can be developed for diverse platforms, created using all of the features of different platforms, while minimizing their complexities and disparities. DOME addresses application development with a layered approach. Figure 1 above [where?] shows DOME, the relationships of the various components or services, and how they communicate with one another. Suite's DOME 3.0 lays the foundation for a truly distributed computing environment. All basic functionality needed to create a true Distributed Object Management Environment are present. The business benefits of DOME are time and money. DOME reduces the time needed to build applications that work across distributed and heterogeneous environments. All companies today face the problem that old applications run on physically disparate environments. The DBMSs, network protocols and operating systems are not homogenous. New application development is being forced to build applications that work with the old applications. Computers on the desktop are a reality. DOME facilitates building new applications that take advantage of the new high performance workstations while making it easy to tie the new applications to the old applications, i.e., application interoperability. All of this can be done much easier and quicker, with fewer maintenance problems with DOME.

The Computer Algebra Kit comes with the source of an application, called "MySystem", consisting of trivial subclasses of the classes in the toolkit. Once compiled however, this small system provides interactive access to many of the features of the Computer Algebra Kit. The "MySystem" application can be used as a shell for adding functionality to the Computer Algebra Kit, by extending the subclasses, or as a starting point for building your own symbolic "front-end" system to numerical code. Version: 1.2.2 Number of Objects: 15 Key Objects: - Integer object for fast, exact, multiprecision integer arithmetic - Polynomial object for advanced, polynomial arithmetic, over arbitrary domains - Matrix object for working with matrices of polynomials, fractions etc. Binary Bulk of Library: between 1.0 and 1.5 MB dep. platform Source Bulk of Library: about 65,000 lines of generated Objective C Portability: Stepstone, GNU, NeXT Objective C compatible Platforms: Linux, SunOS, Solaris, AIX, IRIX, NeXT available now, others coming soon!

The Objective-Framework from TipTop Software (http://www.tiptop.com) system provides true language independence to the Objective-C (e.g., OpenStep) object model. Objective-Framework provides a seamless integration of the Objective-C runtime system with other languages. Objective-Framework not only breaks the barrier between interpreted and compiled code, but it also breaks the barrier between various programming languages! Objective-Tcl and Objective-Perl are two languages currently available. More to come... Some of the benefits of Objective-Framework include: - Rapid application prototyping and development environment. The Objective-Framework languages, Objective-Tcl and Objective-Perl, provide a dynamic interactive interpretive environment. You get immediate feedback to all your programming actions in this environment, so you can prototype and develop much more rapidly. You can define and redefine classes on-the-fly, at runtime, skipping the traditional code-compile-lik-debug development cycle. - True language independence. You can seamlessly mix-and-match languages. Thus you can use Objective-Perl for heavy-duty text processing, use Objective-Tcl for highly interactive (e.g., exploratory) programming, etc. Classes can have mixed implementation; certain methods can be implemented in Objective-C, other methods can be implemented in Objective-Tcl, yet some other methods can be implemented in Objective-Perl, etc. It is transparent and irrelevant to the sender of a message which language implements the corresponding method---the method looks "native" to the caller. - Extend existing applications. The Objective-Framework runtime library can be linked with any NEXTSTEP/OpenStep application to easily provide a high-level control (scripting) languages. - Interactive Enterprise Object Framework (EOF) development environment. Objective-Tcl and Objective-Perl are very useful for EOF development, since this kind of development consists of writing high-level glue code which is hard to write in a low-level compiled language such as Objective-C, and easy to write in high-level languages such as Tcl or Perl. - Testing environment. Objective-Tcl and Objective-Perl are ideally suited for regression testing. A more detailed description of the Objective-Framework functionality is availble at http://www.tiptop.com/Objective/WhitePaper.htmld/. See also http://www.tiptop.com for more info. Fully functional evaluation version is available: ftp://ftp.tiptop.com/pub/Objective/ObjSys.pkg.tar Objective-Browser Objective-Browser (OB) is a graphical runtime introspection and debugging tool. The browser allows you to view live objects within a running application in many object-specific ways. OB allows you to easily investigate the structure and methods of various objects and classes. For example, methods, instance variables, and other object information can be viewed and edited during execution. To a user, OB appears as a hierarchical browsing tool, similar to the file system browser. Each node in the browser represents an object or some other piece of information (e.g., a method) with an arbitrary number of subnodes. For example, when looking at an object, instance variables or methods appear as subnodes. OB is extensible. You can provide object-specific browser nodes and custom inspectors for any object in the system. OB can be used from any application which is linked with the Objective-Tcl runtime---the browser is dynamically loaded when needed.

The library requires gcc 2.7.0 or later and libobjects 0.1.10 or later. Because we built this library to support porting NeXTSTEP applications to X/Motif and because our GUI programming experience has been with NeXTSTEP, this class library has a strongly resemblance to NeXT's AppKit. However, it is only a Objective-C wrapper to Motif widgets and does not support Display PostScript, rich text, pasteboard, drag and drop, services or many other things associated with the NeXTSTEP environment that are not available under X windows. From version 0.8, the nib translator is part of the objcX distribution, as well as some examples of using objcX. These announcements are also a call for help. The library and the translator program could use much more work in two areas... - first the library could be flushed out with more features to support larger applications - second, I would like to contribute the library to the GNU project. But it is based on Motif widgets which is not free software. Thus, work is needed to replace Motif widgets with widgets based on free software.

From Tcl you can send messages to Objective-C objects and get textual representations of what's returned. Thus it provides a way to interactively type messages and see the results, all inside the rich structure of the Tcl scripting language---almost an Objective-C interpreter. The library also provides an Objective-C object that will forward all of its messages to the Tcl interpreter in textual format. The library does NOT provide: * Handling arguments of non-atomic C types. * Tk widgets based NeXTSTEP AppKit objects. * The ability to create new Objective-C classes or methods from Tcl. The library is available by anonymous ftp at ftp.cs.rochester.edu:pub/libcoll/libtclobjc-1.0.tar.gz The library requires gcc (2.5.8 or higher) or NeXT's cc and tcl-7.3. If you have tk-3.6, the library can be configured to use it. If you have libreadline, the library can be configured to use it. Gcc and libreadline are available at any of the GNU archive sites; tcl and tk are available at ftp.cs.berkeley.edu. Contact R.

(It is neither common lisp nor emacs lisp; it is probably best described by the name tiggr's lisp.) TL provides mark & sweep garbage collection to instances of TLObject or a subclass thereof. TL provides the following classes: The `root' object TLObject, a patch for existing root objects (like TLPatchObject), TLString (and TLMutableString), TLRange, TLDictionary plus enumerators (TLDictionaryEnumerator, TLDictionaryDictEnumerator, TLDictionaryKeyEnumerator, TLDictionaryValueEnumerator), basic streams (TLFDStream, TLFILEStream), TLSocketStream (TLInetSocketStream, TLUnixSocketStream) plus addresses (TLInetAddress, TLUnixAddress), TLStringStream (TLConstantStringStream, TLMutableStringStream), TLBase64Stream (TLBase64InputStream, TLBase64OutputStream), various other streams (TLBufferedStream, TLHTTPStream, TLSneakStream, TLStreamStream, TLSyslogStream, TLTelnetStream, TLWrapStream), lisp specific classes (TLCons, TLConsEnumerator, TLLDelegate, TLLInvocation, TLLLambda, TLLLex, TLLSubroutine, TLLTag, TLNil, TLSymbol, TLSymbolValue) and various others: TLDate, TLMimeItem, TLNumber, TLRunLoop, TLURL, TLVector and TLVectorEnumerator. Furthermore, it includes a host of Lisp invokable (but C written and thus also C invokable) functions. If reference counting is not provided by another library, TL provides reference counting and an NSAutoreleasePool. TL has been tested on HP9000/735 HP-UX 9.05 with the GNU runtime, and on a NeXTstation Mono Turbo NS3.3 with the NeXT runtime. TL is distributed under the GNU General Public License. TL comes WITHOUT ANY WARRANTY. See the file LICENSE in the TL distribution for details. TL is available through anonymous FTP at ftp://ftp.es.ele.tue.nl/pub/tiggr/tl.tar.gz.

It recreates the shelves, browsers, folders, and suitcases that are present throughout the basic NEXTSTEP applications: - The file browser and shelf in Workspace. - The bookshelves in Librarian. - The project browser in ProjectBuilder. - The suitcases in InterfaceBuilder. - The feature browser used to configure a DBTableView. IconKit contains all the objects one needs to build new applications of this kind. It is fully integrated with InterfaceBuilder, providing a palette and inspectors for all the IconKit classes. It comes complete with source code, documentation, and an example application that mimics the NEXTSTEP Workspace file viewer. IconKit is freely distributable and free for noncommercial use. It costs money for a commercial license, but you are allowed to use IconKit get your application working before deciding whether to purchase it. The General Objectware License that covers this policy is broadly applicable, and other developers are encouraged to adopt it for their own software. IconKit should work on any system running NEXTSTEP 3.0 or later. Distribution ------------ IconKit may be freely distributed, in whole or in part, provided only that the included ReadMe file and the General Objectware License are neither removed nor altered in any way. The complete kit is available from either of the two archive locations, ftp.cs.orst.edu: /pub/next/sources/objects/IconKit-1.2.* /pub/next/binaries/util/FileViewer-1.2.* ftp.informatik.uni-muenchen.de /pub/comp/platforms/next/Developer/objc/iconkit/IconKit-1.2.* FileViewer is a compiled MAB version of an example application that recreates the NEXTSTEP file browser. Complete source is included in IconKit-1.2. In the event that you cannot locate IconKit at either of these two locations, you should contact the author to receive the complete distribution. All questions and correspondence are welcome! Contact H. Scott Roy 2573 Stowe Ct. Northbrook, IL 60062-8103 email: hsr@cs.stanford.edu Various authors MiscKit [Abridged press release]. ANNOUNCING THE RELEASE OF THE MISCKIT VERSION 1.8.0 Update to Kit of Free Objective-C Objects Is Now Available PROVO, UT, Sept. 5, 1996 -- A new release of the MiscKit has been made publically available. It contains many new objects and fixes all problems reported since the previous release. The MiscKit may be obtained via ftp to any of the following site: ftp://next-ftp.peak.org/pub/next/sources/classes/MiscKit1.8.0.s.gnutar.gz ftp://ftp.thoughtport.com/pub/next/misckit/MiscKit1.8.0.s.gnutar.gz ftp://ftp.informatik.uni-muenchen.de/pub/comp/platforms/next/Developer/objc/misckit/MiscKit1.8.0.s.gnutar.gz The binary packages are not available at this time, but will be made available as soon as possible--which, due to time constraints, will likely not be until the end of September at the soonest. The thoughtport.com site always has the most recent official MiscKit distribution available in /pub/next/misckit with all previous versions archived in /pub/next/misckit/old. The MiscKit is an easy to install kit consisting of Objective-C objects, Interface Builder palettes, bundles, and other useful programming resources. All the resources in the MiscKit have been donated by various Internet personalities for the benefit of other NEXTSTEP programmers. Objects include data structures (string, tree, stack, queue, priority queue, linked list), interface widgets (find panel, textfield, button and slider subclasses, clock and calendar views, icon wells, progress pie/bar), macros, other useful objects (lock file, log file, time, stopwatch, serial port, colors, subprocess, remote subprocess, file), frameworks for building complex interfaces (MiscMergeKit, MiscInspectorKit, InfoMenuKit) and even some useful example applications...plus much more! To make the MiscKit more attractive to developers, use of the MiscKit resources is absolutely free of charge, no matter how the resources are used. Redistribution of the MiscKit is also encouraged. Many developers are reluctant to use objects which are under the GNU "Copyleft". As a result, the MiscKit has its own license which allows developers to reuse the code freely, even in commercial projects. Everything possible has been done to encourage the use of the MiscKit to speed development efforts. Any developer who has generally useful objects, palettes, or other programming resources and would like to donate them to the MiscKit effort is welcome to do so. Contact Don Yacktman at don@misckit.com for information on how to prepare a MiscKit submission. By making a submission to the MiscKit, a developer can avoid the hassles of packaging up a formal distribution of their resources and in turn help add to a growing centralized pool of useful resources. The misckit mailing lists are temporarily out of order and we hope to have them up and working at a new site soon. Until then, inquiries and subscription requests should be made to don@misckit.com. If you request a subscription, be sure to specify whether you wish to be part of the development discussion or only receive MiscKit-based press releases. When the mailing lists are once again up and running, a press release will be sent out to and let everyone know about the changes in addresses and any other important details. Please note that the creation of the "misckit.com" domain does NOT mean that the MiscKit is "going commercial" in any way--it will always be free and open as it has been in the past. Nothing has changed and NO special significance should be read into the use of ".com" instead of ".org". The MiscKit has evolved from the DAYMiscKit and several objects released over the past few years by Don Yacktman and other USENET personalities. Contact Don Yacktman (801)221-0344 don@misckit.com CCRMA MusicKit The Music Kit provides tools for designing music applications. These tools address three topics: music representation, performance, and synthesis (digital sound generation and processing). The Objective-C classes defined in the Music Kit fall neatly into these three areas. The design goal of the Music Kit is to combine the interactive gestural control of MIDI with the precise timbral control of MUSIC 5-type systems in an extensible, object-oriented environment. To this end, the Music Kit is capable of fully representing MIDI. The Music Kit accepts MIDI in and can send MIDI out through the two serial ports at the back of the computer. Nonetheless, the Music Kit isn't limited by the MIDI specification; for example, its resolution of frequency and amplitude is much finer than MIDI's highly quantized values. The Music Kit generates sounds by sending synthesis instructions to the DSP. The generality of the synthesis software far surpasses that of commercial synthesizers. While most synthesizers employ only one type of synthesis-the Yamaha DX-7 uses only frequency modulation, for example-the Music Kit can implement virtually any sound synthesis strategy. And since the synthesis engine (the DSP) and the control stream are brought together in a single high-performance computer, the Music Kit makes possible an unprecedented level of expressive control. (from Documentation/MusicKit+DSP/General/SoundMusicDSP.rtfd) MusicKit used to be supplied by NeXT as part of NeXTSTEP (pre 3.0). It is now maintained by CCRMA and available in two packages: ftp://ccrma-ftp.stanford.edu/pub/NeXT/MusicKit_4.1.1.pkg.tar NI-fat Class library, header files, documentation, programming examples, and a suite of applications (size = 13MB). ftp://ccrma-ftp.stanford.edu/pub/NeXT/MusicKitSource_4.1.1.pkg.tar Source of the MusicKit class library (size = 5MB). Contact email: musickit@ccrma.stanford.edu ObjectPak `ObjectPak' is not just `another' collection class library. ObjectPak is a rewrite from scratch of the objects described in Brad Cox' book. ObjectPak is largely compatible in interface with the collection classes of Stepstone's ICpak101 (but not with the ICpak101 foundation classes), and hence also with the Smalltalk Collection Classes from Adele Goldberg's book. The library comes with source code, header files, RTF and HTML documentation. Runtime dependencies are left out of ObjectPak. You can therefore work with the same objects on any current or future implementation of Objective C, yet take advantage of each particular environment: ObjectPak has been tested on NextStep, Stepstone and GNU Objective C, and has been ported to several Unix platforms (Linux, Solaris, AIX). Classes in ObjectPak -------------------- ObjPak root class of ObjectPak ObjStr string objects ObjCltn collections of objects, ordered ObjSet sets of objects, no duplicate entries ObjDic dictionaries, key-value tables ObjSort instances keep their contents sorted in a tree ObjSeq sequencing over groups of objects ObjectPak is an ideal starting-point for writing all sorts of text filters or processors in Objective C : as a demonstration of what can be done, the library comes with a small program to print a collection, a set without duplicates, a dictionary or a sorted list of the words in a text file. ObjectPak is public domain software; get a copy from the Computer Algebra Objects web-site, located at "http://www.can.nl/~stes".
