This file contains information about GNU Emacs on "Nextstep" platforms.
|
||
The Nextstep support code works on many POSIX systems (and possibly
|
||
W32) using the GNUstep libraries, and on macOS systems using the Cocoa
|
||
libraries.
|
||
|
||
Background
|
||
----------
|
||
Within Emacs, the port and its code are referred to using the term
|
||
"Nextstep", despite the fact that no system or API has been released
|
||
under this name in more than 10 years. Here's some background on why:
|
||
|
||
NeXT, Inc. introduced the NeXTstep API with its computer and operating
|
||
system in the late 1980's. Later on, in collaboration with Sun, this
|
||
API was published as a specification called OpenStep. The GNUstep
|
||
project started in the early 1990's to provide a free implementation
|
||
of this API. Later on, Apple bought NeXT (some would say "NeXT bought
|
||
Apple") and made OpenStep the basis of Mac OS X, calling the API
|
||
"Cocoa". Since then, Cocoa has evolved beyond the OpenStep
|
||
specification, and GNUstep has followed it.
|
||
|
||
Thus, calling this port "OpenStep" is not technically accurate, and in
|
||
the absence of any other determinant, we are using the term
|
||
"Nextstep", both because it signifies the original inspiration that
|
||
created these APIs, and because all of the classes and functions still
|
||
begin with the letters "NS".
|
||
|
||
(See http://en.wikipedia.org/wiki/Nextstep)
|
||
|
||
This Emacs port was first released in the early 1990's on the NeXT
|
||
computer, and was successively updated to OpenStep, Rhapsody, Mac OS
|
||
X, and then finally GNUstep, tracking GNU Emacs core releases in the
|
||
meantime.

|
||
paste from other applications. File icons

||
mouse highlighting rendering bugs
|
||
fixed. Drag/drop and cut/paste interaction

|
||
|
||
2005/02/27 8.0-rc1 Dynamic path detection at startup so Emacs.app
|
||
can be moved anywhere. Added binary packages
|
||
and simplified source installation to running
|
||
two scripts. Thorough cleanup of menu code;

||
now fully functional. Fixed all detected

memory leaks. Minor frame focus and title
|
||
bugs fixed.

|
||
2005/03/30 8.0-rc2 "Configure" info directory now uses dynamic

|
||
GNUstep, and now works under Art backend.

|
||
and Planner go away. Improved scrollbar

||
handling and rendering speed. Color panel
|
||
and other bug fixes. mac-fix-env utility.
|
||
Font handling improvements (Mac OS X 10.3,

- heed 'GSFontAntiAlias' default
|
||
- heed system antialiasing threshold
|
||
- added 'UseQuickdrawSmoothing' default to
|
||
invoke less heavy antialiasing
|
||
|
||
2005/07/05 8.0-rc4 Added a Preferences panel. Cleaned up
|
||
rendering for synthetic italic fonts. Further
|
||
improved menu parsing. Use system highlight
|

|
||
Miscellaneous bug fixes.
|
||
|
||
2005/08/04 8.0-rc5 All internal string handling changed to UTF-8.
|
||
This means menu items, color and color list
|
||
names, and a few other things will now display
|
||
properly. It does NOT mean UTF-8 filenames
|
||
are displayed correctly in the minibuffer.
|
||
Also relating to UTF-8, contents of files
|
||
using this coding can now be displayed (though
|
||
not auto-recognized; add extensions to your

||
support was also added (also sans recognition).
|
||
Certain characters are not displayed properly
|
||
due to a translation problem. (UTF-8 based on
|
||
work by Otfried Cheong; mac-roman from
|
||
emacs-21.) Partial support for "dead-key"
|
||
handling now added. Transparency (e.g., M-x
|
||
set-background-color ARGB88FFFFFF) improved:
|
||
only the background is made transparent.

|
||
handling improved. Fixed some portability
|
||
problems on Tiger and Puma.

other people on the mailing list from whom we didn't hear much, but
|
||
the presence of which assured us that maybe this project was actually
|
||
worth doing.
