Annotation of OpenXM_contrib/gnuplot/docs/old/README.nex, Revision 1.1

1.1     ! maekawa     1: The 3.6 version of gnuplot is proud to include a new NeXTstep
        !             2: terminal driver.  The new driver offers the following new
        !             3: features:
        !             4:
        !             5: 1) Multiple windows
        !             6: 2) Resizable windows
        !             7: 3) Direct print interface from windows
        !             8: 4) Titleable and re-addressable windows
        !             9: 5) A real NeXTstep-style interface to the terminal driver
        !            10:
        !            11: The driver runs as a separate application, and hence has
        !            12: it's own set of controls and interfaces.  It registers itself
        !            13: with the operating system as a distributed objects "GnuTerm"
        !            14: server, and thereafter accepts requests from any gnuplot instances
        !            15: on the machine.
        !            16:
        !            17: Nick Strobel's original single-viewport NeXTstep terminal is available
        !            18: as an option to the next terminal.  It can be invoked from the gnuplot
        !            19: command line as:
        !            20: gnuplot>  set term next old
        !            21: There are several reasons why one might choose the older terminal.
        !            22: First, the new terminal will probably not work on NeXT systems
        !            23: running a pre-3.0 version of the operating system.
        !            24: Second, because all of the postscript must be buffered in order
        !            25: to allow re-sizing and printing of the window's contents, the
        !            26: new terminal can be a memory hog for very complicated plots.
        !            27: The original README.nex file for the original next terminal is
        !            28: included at the end of this document.
        !            29:
        !            30:
        !            31: Installation
        !            32: ------------
        !            33:
        !            34: In addition to enabling the #include next.trm in term.h before
        !            35: compiling gnuplot, the GnuTerm.app application must be separately
        !            36: built and installed.  All of the source code is included in
        !            37: the NeXT subdirectory of the gnuplot distribution.  GnuTerm.app
        !            38: can be built for the current architecture by cd-ing to the NeXT
        !            39: directory and type "make".  For more complicated installations,
        !            40: or to build the application "FAT" (to run on more than one
        !            41: processor architecture), it's easiest to fire up NeXT's
        !            42: ProjectBuilder.app and open NeXT/PB.project.
        !            43:
        !            44: GnuTerm.app can be installed in any directory contained in the
        !            45: WorkSpace's ApplicationPaths dwrite.  For most situations,
        !            46: this means installing GnuTerm.app in either /LocalApps or
        !            47: ~/Apps.
        !            48:
        !            49: If you wish to locate the GnuTerm.app somewhere other than ~/Apps
        !            50: or /LocalApps, you can "setenv GNUTERMPATH  /newpath" to tell
        !            51: gnuplot where to find it.
        !            52: Example (wherein GnuTerm.app is in /LocalApps/Data):
        !            53:
        !            54: host%  setenv GNUTERMPATH "/LocalApps/Data"
        !            55:
        !            56: Robert Lutwak
        !            57: robert@amo.mit.edu
        !            58: July 14, 1996
        !            59:
        !            60:
        !            61: Following is the README.nex that accompanied the original
        !            62: (single viewport) next terminal, which is still accessible
        !            63: as "set term next old".
        !            64: -------------------------------
        !            65:         This directory contains version 2 of the additional files
        !            66: you'll need to get gnuplot3.0 to display it's postscript directly to a
        !            67: window instead of going through the klunky process of writing the
        !            68: postscript to a file and launching Previewer to view the file.  Note
        !            69: that all input is still done at the shell level! Fancier NeXTStep
        !            70: interfaces will be a future project.
        !            71:
        !            72:         This version is faster and leaner than the old method.  It
        !            73: also does not eat up swap space like the older version (this was
        !            74: particularly noticeable when doing animation-like plots).  To do this
        !            75: I used DPS function calls instead of creating a NXImage and
        !            76: compositing the stream of commands. I based my code on the program
        !            77: called "epsview" in the hackkit tar file on the archive servers.
        !            78:
        !            79:         The next.trm (next terminal) is basically the post.trm
        !            80: (postscript terminal) with the fprintf replaced by DPSPrintf and
        !            81: outfile by the DPSContext d.  You'll also see that I also used some
        !            82: code (with modifications) from David S. Joerg's MovieApp.  Using the
        !            83: DPS functions enabled me to slim down the EpsViewer.[hm] and
        !            84: EPSView.[hm] files.
        !            85:
        !            86:         No claim is made to code elegance or to it being a good example of
        !            87: objective-c coding.  This is my first (well, second, sort of) objective-c
        !            88: program. It seems to work for me. Any constructive criticism would be
        !            89: appreciated.  I can be reached at strobel@phast.phys.washington.edu
