NeXT

    Common Classes

    Several classes provided with NeXTSTEP do not belong to a specific
    kit: Object (core of the runtime system, root of the general class
    hierarchy), Storage, List (an abstract array), HashTable (to store
    (key, object) associations), StreamTable (to write data to streams)
    and NXStringTable (to store (key, string) associations).

    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.

    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.

    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"

    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.

    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.

    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.

    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.

    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.

FSF

    Object

    Object is the root class which comes as part of the Objective-C
    runtime library provided with the GNU CC compiler.

    Collection Library

    The Collection Library is a library of Objective-C objects with
    similar functionality to Smalltalk's Collection objects.  It
    includes: Set, Bag, Array, CircularArray, GapArray, Queue, Stack,
    Heap, LinkedList, BinaryTree, SplayTree, RBTree, Dictionary,
    MappedCollector, EltNodeCollector and DelegateList.

    Outside of its main hierarchy it also includes List, HashTable and
    Storage objects compatible with NeXT's objects of the same name.

    An alfa release of the Collection Library can be obtained by FTP
    from cs.rochester.edu:/pub/libcoll/libcoll-yymmdd.tar.gz, in
    which `yymmdd' is a string of digits specifies its date.

    The Collection Library needs GCC 2.5.0 or a more recent version
    to be compiled.

    BARCODEKIT

        BarCodeKit is a comprehensive collection of object palettes for
        creating international standard bar codes.  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.  Requires SerialPortServer
        or SerialPortServer Lite which are available also from Hot
        Technologies.

GPL Kits

   objcX

    An alpha version of an GNU Objective-C class library for X/Motif
    Windows is available via anonymous ftp from

        ftp.slac.stanford.edu:pub/sources/objcX-0.6.tar.gz.

    For lack of a good witty name, the library is called objcX.

    The library requires the List class from the Collection Library for
    GNU Objective-C (libcoll).

    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.

    Also available, for a NeXTSTEP platform only, is a program that
    converts an object archive file generated by the InterfaceBuilder
    (.nib file) into a GNU object archive file usable by the objcX class
    library.  It is available from

        ftp.slac.stanford.edu:pub/sources/trnib-0.5.tar.gz

    This program requires NeXTSTEP developer and gcc.

    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.

    Tiggr's Objective-C Library

    Tiggr's Objective-C Library, or tobjc for short, is a basic
    Objective-C library, whose functionality is based on Lisp.

    tobjc provides the following classes: LispObject, LispVector,
    Cons, Double, Integer, String, AVLTree, THashTable, StringTable,
    Trie, Lex, LexC and LexDFG.  Furthermore, tobjc includes a
    program to extract documentation from Objective-C source files.

    All classes are a subclass of LispObject.  The LispObject class
    provides its allocation routines and garbage collection (through
    class abstraction) to its subclasses.

    tobjc is undergoing continuous development.  Test releases can
    be obtained by anonymous FTP to `ftp.es.ele.tue.nl' as
    `/pub/objc/tobjc-x.xx.tar.gz', where `x.xx' is some version
    indication.  It is by no means finished yet, but certainly
    useful (I have used it for developing a VHDL->ASCIS DFG compiler).

    MiscKit

        The MiscKit is a collection of over sixty objects which extend
        the NEXTSTEP Objective-C development environment in various
        ways.  It includes palletized subclasses of AppKit controls,
        foundation objects, and a variety of useful special purpose
        objects.

        Objects include strings, basic data structures, and kits for
        building swapping views and inspectors.  There are also
        frameworks for building Info menus and a generic document
        handling architecture.  Palettized objects include a logarithmic
        and circular sliders, a tri-state button, a combined Slider and
        TextField, and a read-only NXColorWell.  There are other
        objects, functions, and useful macros in the kit as well.

        Documentation, examples, tutorials, and complete source code are
        distributed with the MiscKit.  The kit itself is the product of
        over 25 Usenet personalities and is available for use in any
        project free of cost.  The only restriction is that you
        acknowledge use of the kit in your project.

    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 by FTP from
        ccrma-ftp.stanford.edu.  There are two packages:

        pub/MusicKit_4.0.pkg.tar

            Class library, header files, documentation, programming
            examples, and a suite of applications (size = 9MB).

        pub/MusicKitSource_4.0.pkg.tar
            Source of the MusicKit class library (size = 7MB).
