   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 Requirements
  14 ------------
  15 MacOS X 10.4 or later
  16
  17 - or -
  18
  19 GNUstep "Startup 0.23" or later
  20 Tested on GNU/Linux, should work on other systems, perhaps with minor
  21 build tweaking.

  24 Background
  25 ----------
  26 Within Emacs, the port and its code are referred to using the term
  27 "Nextstep", despite the fact that no system or API has been released
  28 under this name in more than 10 years.  Here's some background on why:
  29
  30 NeXT, Inc. introduced the NeXTstep API with its computer and operating
  31 system in the late 1980's.  Later on, in collaboration with Sun, this
  32 API was published as a specification called OpenStep.  The GNUstep
  33 project started in the early 1990's to provide a free implementation
  34 of this API.  Later on, Apple bought NeXT (some would say "NeXT bought
  35 Apple") and made OpenStep the basis of OS X, calling the API "Cocoa".
  36 Since then, Cocoa has evolved beyond the OpenStep specification, and
  37 GNUstep has followed it.
  38
  39 Thus, calling this port "OpenStep" is not technically accurate, and in
  40 the absence of any other determinant, we are using the term
  41 "Nextstep", both because it signifies the original inspiration that
  42 created these APIs, and because all of the classes and functions still
  43 begin with the letters "NS".
  44
  45 (See http://en.wikipedia.org/wiki/Nextstep)
  46
  47 This Emacs port was first released in the early 1990's on the NeXT
  48 computer, and was successively updated to OpenStep, Rhapsody, OS X,
  49 and then finally GNUstep, tracking GNU emacs core releases in the
  50 meantime.

 108
 109 2005/02/27      8.0-rc1         Dynamic path detection at startup so Emacs.app
 110                                 can be moved anywhere.  Added binary packages

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

 123                                 Non-Latin text rendering works (but not
 124                                 fontsets), and LEIM is bundled.  UTF8 is used

 134                                 Font handling improvements (OS X 10.3, 10.4):
 135                                 - heed 'GSFontAntiAlias' default
 136                                 - heed system antialiasing threshold
 137                                 - added 'UseQuickdrawSmoothing' default to
 138                                   invoke less heavy antialiasing
 139

 141                                 rendering for synthetic italic fonts.  Further
 142                                 improved menu parsing.  Use system highlight
 143                                 color.  Added previous- and next-mark history
 144                                 navigation commmands bound to M-p,M-n.
 145                                 Miscellaneous bug fixes.
 146
 147 2005/08/04      8.0-rc5         All internal string handling changed to UTF-8.
 148                                 This means menu items, color and color list
 149                                 names, and a few other things will now display
 150                                 properly.  It does NOT mean UTF-8 filenames
 151                                 are displayed correctly in the minibuffer.
 152                                 Also relating to UTF-8, contents of files
 153                                 using this coding can now be displayed (though
 154                                 not auto-recognized; add extensions to your
 155                                 default coding alist).  Limited mac-roman
 156                                 support was also added (also sans recognition).
 157                                 Certain characters are not displayed properly
 158                                 due to a translation problem.  (UTF-8 based on
 159                                 work by Otfried Cheong; mac-roman from
 160                                 emacs-21.)  Partial support for "dead-key"
 161                                 handling now added.  Transparency (e.g., M-x
 162                                 set-background-color ARGB88FFFFFF) improved:
 163                                 only the background is made transparent.
 164                                 Cursor drawing glitches fixed.  Preferences
 165                                 handling improved.  Fixed some portability
 166                                 problems on Tiger and Puma.
 167
 168 2005/09/12      8.0             Bundled ispell on OS X.  Minor bug fixes and
 169                                 stability improvements.  Compiles under gcc-4.
 170
 171 2005/09/26      8.0.1           Correct clipped rendering for synthetic
 172                                 italics. Include the info directory.
 173                                 Fix grabenv. Bundle whitespace package.
 174
 175 2005/10/27      8.0.2           Correct rendering for wide characters during
 176                                 cursor movement.  Fix bungled hack in ispell
 177                                 bundling.
 178

 185                                 (fixes inaccurate page up/down, window size,
 186                                 and partial lines).  Support better remapping
 187                                 of Alt/Opt and remapping of Command.  More
