Short: GNU Emacs-20.3 V2.10 Intuition 32bit
Uploader: bertw@knuut.de (Bert Winkelmann)
Author: Patched by bertw@knuut.de (Bert Winkelmann)
Type: util/gnu
Requires: OS-v39 (for GUI), 8MB RAM, 68ec20, IxEmul library
Version: AmigaOS patchlevel 2.10
This distribution holds version 20.3 of GNU Emacs, the extensible,
customizable, self-documenting real-time display editor.
{Sorry about my bad English.}
This Amiga port, like most IxEmul ports, is probably more close to its
baseline version than previous ports. Despite of this, it haves also
some of the Amiga features (ARexx, AppWindow, ASL). The Intuition
based GUI is very similar to the X GUI. You should be able to use all
GUI based Lisp applications without making any adaptions.
Normally you may want to use this program with Intuition, but you can
also use it on terminals via AUX:. It's also possible to run it on X,
but you need a different configured programfile version for that.
Amiga related Features
======================
AREXX port (not in X nor TTY-only versions)
Intuition-GUI: multiple colors and font styles * multiple frames
(Intuition windows) on one or more public screens (and invisible
frames too) * vertical scroll bars * pens are not really obtained from
system until first use in drawing. * Workbench iconify and drag'n'drop
* clipboard support * pop-up menu (configurable, scroll-able, full
keyboard control) * ASL file+font requester (used by "Amiga" menu) *
provides most of old "amiga-" LISP-functions for compatibility with
formerly Emacs-18 AmigaOS port (e.g. amiga-set-geometry) * 2 different
modes for numeric keypad (NumLock) * provides Meta, Super and Hyper
modifier keys
Console: amiga-set-font implements font changing on CON:
TTY: you can open a sub shell if your shell implements no job-control.
Version Numbers
===============
There are two version numbers. One ist the baseline version number
(20.3). Note that the diff archives contains currently patches for
two different baseline versions (19.34 and 20.3).
The other number specifies the version of my patches (like V2.10).
The current version is V2.10. The version for the binary main archive
is still V2.9. It will be updated automatically if you install any of
the program archive on top it (they contain not only the program files
but also some updates to the main archive too (delta update)).
Parts of this Distribution
==========================
There exists both a source and binary distribution.
Source Code
-----------
The source distribution comes in to different forms: a small diff
archive and a big complete archive.
------------------ ----------------------------------------
em203dif.lha - GNU Emacs 20.3 V2.10 diffs
em203src.lha - GNU Emacs 20.3 V2.10 source
------------------ ----------------------------------------
Note: The LhA archives contain "tar.gz" or even "tar.bz2" archives.
You need a "tar" unarchiver (tar/untar) and the right decompression
programs (gzip for .gz; bzip2 for .bz2). I will limit the use of
bzip2 to the really big (and rather uninteresting) source archive.
Note: If you want to compile Emacs yourself and having acces to the
original baseline sources, you need only the diffs archive. All you
have to do ist invoking "sh install.sh 20.3 src/emacs-20.3" to patch
the source. It's tested.
Binaries
--------
The binary distribution consist of a single main archive and some
Emacs program files (in different flavors). Note: The installation
should go into the "gg:" directory. This could be a multi-assign too.
Emacs depends on this. Please read the README* file in the program
archive to learn how to make the dumpfile (it's very easy now).
Note: Install the main archive *before* the program archive.
Otherwise the newer files in the program archive would be overwritten
by older versions from the main archive.
------------------ ----------------------------------------
em203bin.lha - GNU Emacs 20.3 V2.9 installed in gg:
em203i0.lha - GNU Emacs 20.3 V2.10 Intuition 28bit
em203i1.lha - GNU Emacs 20.3 V2.10 Intuit. 28bit-seg
em203i3.lha - GNU Emacs 20.3 V2.10 Intuition 32bit
------------------ ----------------------------------------
optional more exotic flavors:
------------------ ----------------------------------------
em203x0.lha - GNU Emacs 20.3 V2.10 X 28bit
em203x1.lha - GNU Emacs 20.3 V2.10 X 28bit-seg
em203x3.lha - GNU Emacs 20.3 V2.10 X 32bit
em203t0.lha - GNU Emacs 20.3 V2.10 CON/AUX 28bit
em203t1.lhaa - GNU Emacs 20.3 V2.10 CON/AUX 28bit-seg
em203t3.lha - GNU Emacs 20.3 V2.10 CON/AUX 32bit
------------------ ----------------------------------------
What does 28, 28s and 32 bit mean?
----------------------------------
If your machine does not have RAM above 28bit, then everything is
fine. Just use the "28bit" version, which is faster than the others:
normal/28 - RAM inside 28bit address range is usable
runs on machines having only RAM upto 0x0fffffff
(use ShowConfig to learn about this)
If your machine has RAM above 28bit you have to use one of the
following flavors which implements segmented RAM. Note: 28s is much
faster than 32.
seg1/28s - RAM inside one 28bit segment is usable (DATA_SEG_BITS feature)
runs on machines with FastMem above 28bit
RAM in range 0xZ0000000..0xZfffffff (i.e. the high nibble (Z)
must be the same for all usable RAM))
seg3/32 - RAM inside 8 independent 25bit segments usable
runs on machines with both FastMem above and below 28bit.
(allows using of mixed RAM not being in a common
28bit block (i.e. with a different high nibble))
Here comes additional info taken from my WWW page.

DESCRIPTION
This project is about running GNU Emacs 19+20 on AmigaOS using the
IxEmul library and GCC. It supports both the native AmigaOS window
system "Intuiton" (>=V39) and X (and of course plain terminals too).
The Intuition GUI implements almost all features of the X GUI except
16bit fonts. You will also get Drag'n'Drop and an ARexx port.
I have tried to make it so compatible as possbile to prevent you and
me from changing any LISP packages. You should never have to change
path syntax, font names, window system names. On the other hand, you
can use ASL file and font requesters via the Amiga menu item. You can
use AmigaDOS path syntax in some LISP commands too.
The current patch-set supports the following baseline versions:
GNU-Emacs-19.34b, 20.2, 20.2.92, 20.2.97, 20.3.
SYSTEM REQUIREMENTS
For using intuition: graphics.library-39 or better is required. (part
of AmigaOS V39)
General: A lot of RAM or virtual memory. A fast CPU is recommended. I
have only an 68030-40MHz which is sometimes too slow even for parts of
some standard ELISP packages.
Note: Different ELISP packages may have very different RAM-/CPU-usage.
LIBRARIES
ixemul.library - the free UNIX kernel emulation + standard C library
(incl. socket interface)
If you want to configure and build Emacs for running on X window
system, you will need the required X libraries and headers. A free
X11R6 package is part of ADE/GG. There are other X window ports, but I
have tested only ADE-X.
NO PROBLEMS
I used Emacs (20.2) mainly as programming environment, to write HTML
and as editor for an external News+Mail-reader.
I have used the following packages very often:
c/c++-mode (indenting slow since 20.2) * font-lock/fast-lock (in 20.2
sometimes you have to restart it because of a not complete fixed bug)
* ETags * sh-mode * Info * Ediff * GUD (for programs using signal
handlers (like Emacs itself) it's better to use gdb on console because
there are no process-groups and Emacs handle/blocks some signals). *
Emacs-Server * HTML-mode * ELISP modes and tools like debuggers and
profilers. * Occur, IMenu, HS
I have tested, but don't use the following packages:
AucTeX (seems to work OK but I don't need it currently) * GNus (works,
but is very slow on my machine) * W3 (works, but is very slow) *
Ange-FTP (needs PTYs, you have to install+run Devs:fifo.handler).
BUILT-IN WORKAROUNDS
HOME variable is translated from AmigaOS to UNIX syntax at startup of
Emacs, EmacsServer, EmacsClient. That means all subprocesses inherit
the UNIX syntax version. (prevents problems by using $HOME as kind of
ID on sockets).
The home directory read from password files will be translated to UNIX
syntax.
A built-in default TERMCAP entry for TERM=amiga exists.
Note: Internally Emacs uses UNIX-path syntax (to gain maximal
compatibility with ELISP packages written for UNIX). I changed a few
user-interface functions to accept both UNIX- and AmigaOS syntax. This
works very well.
The Intuition code inside of Emacs implements serveral X functions
(limited to the needs of Emacs). It even fakes the `window-system'
variable to X. Therefore, any ELisp package written for X should work
without any changes. To check for running on Intuition, you have to
test for (boundp 'amiga-i-windows).
Console: Because `^C' is always handled by console (SIGBREAK_C) there
is a key-translation from C-z to C-c (located in
"lisp/term/amiga.el").
FEATURES
AmigaOS specific: Bidirectional AREXX port as interface to ELISP
language * Two different file-system path syntaxes.
Intuition-GUI: multiple colors and font styles * multiple frames
(Intuition windows) on one or more public screens (and invisible
frames too) * vertical scroll bars * pens are not really obtained from
system until first use in drawing. * Workbench iconify and drag'n'drop
* clipboard support * pop-up menu (configurable, scroll-able, full
keyboard control) * ASL file+font requester (used by "Amiga" menu) *
provides most of old "amiga-" LISP-functions for compatibility with
formerly Emacs-18 AmigaOS port (e.g. amiga-set-geometry) * 2 different
modes for numeric keypad (NumLock) * provides Meta, Super and Hyper
modifier keys
console: amiga-set-font implements font changing on CON:
TTY: you can open a sub shell if your shell implements no job-control.
MULE on Emacs-20: I merged in relevant parts of MBSK to allow
switching it (MBSK) on/off on different window systems. To enable MBSK
it's needed to pass the parameter "no-mule" to "lisp/loadup.el" at
dump-time. The Makefile do handle this automatically (using the
variable LOADUP_ARRGS): MBSK is per default enabled for Intuition-GUI,
but disabled for X.
Example: To always disable MBSK compile with
$ make "LOADUP_ARGS=" ...
To always enable it use
$ make "LOADUP_ARGS=no-mule" ...
BUGS
Intuition: Italic font style is broken (it's nearly unusable for
editing) * Currently no gad-tools menu (we use the pop up menu by the
menu-bar too) * No 16 bit fonts. Use ADE-X to have a full working
MULE. * No working multi keyboard * Never tried a 2 button mouse, but
I guess there are ELISP-packages handling that problem already
MultiUser: I have running MultiUser (mufs) on my system. This causes
the root directory of volume in RAM: having access bits
"700","drwx------". You cannot create files and call DirEd in that
directory. But you can/should change at least the access bits of
sub-directories in RAM: like this:
$ chmod 777 /ram/T /ram/ENV /ram/ClipBoards.
TeX: IxEmul has a problem to pass `\' as part of arguments to all
non-ixemul binaries. This is a problem when using the TeX program from
PasTeX on Meeting-Pearls-CDROM. There is a workaround in directory
`amigaos/' using the small non-ixemul command-shell from
Emacs-18.59-amigaos. Another problem: killing a non-ixemul TeX binary
may crash the system. A ixemul port of TeX may work better. Such one
is part of ADE/GG.
Soft-Links: The clash detection uses soft-links since Emacs-20.2. I
have no problems with this so far. In general, for editing files
visited over a soft-link you may need to use:
(setq find-file-visit-truename t)
in your ~/.emacs file. This may not required if you use the latest
BETA-ffs (http://www.amiga.de). Unluckily, as it seems, there is no
MuliUser patch for that FFS.
