   4 This directory contains the files needed to build Emacs on
   5 Nextstep-based platforms, including GNUstep and Mac OS X.
   6
   7 The Nextstep support code works on many POSIX systems (and possibly
   8 W32) using the GNUstep libraries, and on MacOS X systems using the
   9 Cocoa libraries.
  10
  11 See the INSTALL file in this directory for compilation instructions.
  12
  13 Those primarily responsible for the port were, in chronological order:
  14 Michael Brouwer, Carl Edman, Christian Limpach, Scott Bender,
  15 Christophe de Dinechin, and Adrian Robert.
  16
  17 Peter Dyballa assisted in a variety of ways to improve text rendering
  18 and keyboard handling, Adam Ratcliffe documented the Preferences
  19 panel, David M. Cooke contributed fixes to XPM handling, and Carsten
  20 Bormann helped get dired working for non-ASCII filenames.  People who
  21 provided additional assistance include Adam Fedor, Fred Kiefer, M. Uli
  22 Klusterer, Alexander Malmberg, Jonas Matton, and Riccardo Mottola.
  23 See AUTHORS file and "Release History" below for more information.

  37 Background
  38 ----------
  39 Within Emacs, the port and its code are referred to using the term
  40 "Nextstep", despite the fact that no system or API has been released
  41 under this name in more than 10 years.  Here's some background on why:
  42
  43 NeXT, Inc. introduced the NeXTstep API with its computer and operating
  44 system in the late 1980's.  Later on, in collaboration with Sun, this
  45 API was published as a specification called OpenStep.  The GNUstep
  46 project started in the early 1990's to provide a free implementation
  47 of this API.  Later on, Apple bought NeXT (some would say "NeXT bought
  48 Apple") and made OpenStep the basis of OS X, calling the API "Cocoa".
  49 Since then, Cocoa has evolved beyond the OpenStep specification, and
  50 GNUstep has followed it.
  51
  52 Thus, calling this port "OpenStep" is not technically accurate, and in
  53 the absence of any other determinant, we are using the term
  54 "Nextstep", both because it signifies the original inspiration that
  55 created these APIs, and because all of the classes and functions still
  56 begin with the letters "NS".
  57
  58 (See http://en.wikipedia.org/wiki/Nextstep)
  59
  60 This Emacs port was first released in the early 1990's on the NeXT
  61 computer, and was successively updated to OpenStep, Rhapsody, OS X,
  62 and then finally GNUstep, tracking GNU emacs core releases in the
  63 meantime.

 131                                 path setting, so info files can go under .app.
 132                                 Improved select() handling and PTY fixes so
 133                                 shell mode and tramp run smoothly.

 147                                 Font handling improvements (OS X 10.3, 10.4):
 148                                 - heed 'GSFontAntiAlias' default
 149                                 - heed system antialiasing threshold
 150                                 - added 'UseQuickdrawSmoothing' default to
 151                                   invoke less heavy antialiasing
 152

 154                                 rendering for synthetic italic fonts.  Further
 155                                 improved menu parsing.  Use system highlight
 156                                 color.  Added previous- and next-mark history
 157                                 navigation commmands bound to M-p,M-n.
 158                                 Miscellaneous bug fixes.
 159
 160 2005/08/04      8.0-rc5         All internal string handling changed to UTF-8.
 161                                 This means menu items, color and color list
 162                                 names, and a few other things will now display
 163                                 properly.  It does NOT mean UTF-8 filenames
 164                                 are displayed correctly in the minibuffer.
 165                                 Also relating to UTF-8, contents of files
 166                                 using this coding can now be displayed (though
 167                                 not auto-recognized; add extensions to your
 168                                 default coding alist).  Limited mac-roman
 169                                 support was also added (also sans recognition).
 170                                 Certain characters are not displayed properly
 171                                 due to a translation problem.  (UTF-8 based on
 172                                 work by Otfried Cheong; mac-roman from
 173                                 emacs-21.)  Partial support for "dead-key"
 174                                 handling now added.  Transparency (e.g., M-x
 175                                 set-background-color ARGB88FFFFFF) improved:
 176                                 only the background is made transparent.
 177                                 Cursor drawing glitches fixed.  Preferences
 178                                 handling improved.  Fixed some portability
 179                                 problems on Tiger and Puma.
 180
 181 2005/09/12      8.0             Bundled ispell on OS X.  Minor bug fixes and
 182                                 stability improvements.  Compiles under gcc-4.

 187
 188 2005/10/27      8.0.2           Correct rendering for wide characters during
 189                                 cursor movement.  Fix bungled hack in ispell
 190                                 bundling.

 246
 247 2007/11/19      9.0-rc3         Integrated the multi-TTY functionality from
 248                                 emacs core (however, mixed TTY and GUI
 249                                 sessions are not working yet).  Support 10.5.
 250                                 Give site-lisp load precedence over lisp and
 251                                 add a compile option to prefer an additional
 252                                 directory, use miniaturized miniwindow images
 253                                 in some cases, rename cursor types for
 254                                 consistency w/other emacs terms, improved font
 255                                 selection for symbol scripts.
 256                                 Bug fixes: fringe and bitmap, frame deletion,
 257                                 resizing, cursor blink, workspace open-file,
 258                                 image backgrounds, toolbar item enablement,
 259                                 context menu positioning.
