\quotation{When I starts ZIP, the Xservers crashes.

}You need to get the Xserver patches from MIT. The distribution contains bugs 
in the code for drawing wide lined arcs.


\quotation{When I try to use the preview command in EZ it displays my text 
exactly like I typed it instead of format it through troff: in my preference 
file I have put the following commands:

}\quotation{\quotation{formatcommand: pic /tmp/%s.n : tbl : eqn : troff -ms 
-Tpost :

}}\quotation{\quotation{previewcommand: preview -f -o %s}

}\quotation{note that when I type the following sequence in my typescript, 
everything just works fine:

}\quotation{I have even tried to change the \italic{FormatCommand} and the 
\italic{PreviewCommand} in the AndrewSetup file:

}
Your message indicates that you are writing troff/pic code by hand and 
expecting ez to process it. The formatcommand specifications are to specify 
what programs are to be used to process the troff code that ez generates to 
print it's own styles. Naturally ez quotes any embedded troff code in the text 
itself so that it won't interfere with it's own output. There is a formatnote 
style that can be used to outline code that should be passed through directly 
to the processors, so if you had some pic code embedded in styled text, you 
could try putting it in text and surrounding it with a format note style. Two 
warnings: 1. There is no guarantee that the troff you embed will not clash 
with the troff written by ez to produce unpredictable results. 2. Your format 
command includes the -ms macros. The ez macros can not co-exist with the -ms 
macros. You will probably not get any reasonable output this way.

Subject: calling textview_getdataobject in ness?

\begindata{text,990256}
\textdsversion{12}
\template{messages}
I'd like to get the text object of a textview object in ness, but calls to 
textview_getdataobject(textv) and view_getdataobject(textv) both fail to 
compile -- `expression is of the wrong type':


\example{--$enable class access


}\example{void function addstyle (object textview, marker stylename)

	object text, style, stylesheet

	integer selectionpos, selectionlen


	selectionpos := textview_GetDotPosition(textview)

	selectionlen := textview_GetDotLength(textview)

	\bold{text := textview_getdataobject(textview)}

	stylesheet := text_GetStyleSheet(text)

	if stylesheet = null then

		telluser ("No stylesheet for this object")

		exit function


	end if

	style := stylesheet_Find (stylesheet, stylename)

	if style = null then

		telluser ("No style called " ~ stylename)

		exit function

	end if

	text_AddStyle(text, selectionpos, selectionlen, style)


end function

}
Thoughts?

Andrew patches may be ftped from the directory contrib/R4fixes/andrew on 
expo.lcs.mit.edu. They may also be ftped from the 'patches' directory on 
emsworth.andrew.cmu.edu (Internet 128.2.30.62). For those without ftp access, 
they are also available via a mail server.


To get the patches by mail, address requests to 
andrew-service+archive@andrew.cmu.edu, putting one or more  'get-files' or 
'get-directory'  commands into the body of your message (the subject line is 
ignored).  In addition to whatever mail each command generates, you will 
 receive a confirmation message, with a summary of the results of each 
 request.  If you have any problems with this service, please forward the 
 relevant materials to andrew-service+archive-customer-service@andrew.cmu.edu.


Here is a sample message body, with two commands:


get-files patches/patch.001

get-directory patches


To get the uuencoded compressed version of the current patches, you would want 
the following commands

get-files patches/patch.001

get-files patches/patch.002

get-files patches/patch.003

get-files patches/patch.004

My previous note included as an example 

get-directory patches.

This will recusivly get all the files in that directory, which is probably not 
what you want, as the directory is a link to the ftp directory that contain 
both compressed and uncompressed versions of each patch, and you will end up 
with a lot of redundent stuff. To get a listing of available directorys and 
their contents, send mail to  andrew-service+archive@andrew.cmu.edu containing 
the word 'list'. The keyword 'help' may also be sent for more information.

Is there any data object out there in netland that takes tiff files and reads
them into ez?  Is this possible given Andrew's lack of color support?  I
imagine copying over one "color" at a time from the tiff file and then
changing the foreground color.  This tiff object would sure come in handy.

I've looked at the source for xtiff, and there must be some way to emulate
its XCreateImage call.

And as long as you're reading the rest of this article, anyone got a
pointer for ftp of Volume 2 of the Andrew Programmer's Manual?  We seem to
have misplaced it here.  Or can someone tell me where in the source code it
is supposed to be?

Very curious.  A little playing around shows that the following will compile:


	marker t = view_getdataobject(textview)


so somehow it thinks dataobject is a (char *) instead of a (dataobject *).  Of 
course, this will not give reasonable results for execution.


I'll look into the problem.

mpp is part of the Transarc distribution.  It is used only in pobbconf, which 
is a problematical part of the ATK distribution.  As I understand it, pobbconf 
suggests some things that can be done in installing mail systems, but is not 
actually used as-is anywhere.  Unless you have a good reason to do so, you 
should probably not be compiling pobbconf.

Fred is right; mpp (a simple macro processor) is now distributed by Transarc, 
though I suppose we could find alternate distribution channels as well.


The andrew/overhead/pobbconf directory is unusual since installing it will 
attempt to install all kinds of mail software and startup scripts in various 
paths that are not under DESTDIR or ANDREWDIR.  You should be installing this 
directory only if you know what it will be doing for you; generally, it will 
try to install an Andrew Message Delivery System for you, taking over your 
local mail delivery mechanism, which is a rather heavyweight step.


Even though most Make-ing in the directory ``andrew/overhead'' will recurse 
into subdirectories such as util, cmenu, class, and such, it will never 
automatically recurse into the pobbconf directory.  To install stuff from 
there, you should be following the instructions in the documents in 
andrew/ams/delivery/doc, particularly the AMDS.* files there.


Let me know if you really want to be installing from andrew/overhead/pobbconf 
and whether you need to get mpp from somewhere.

Let me echo Craig's comments about installing the Andrew Message
Delivery System.

Doing so wil replace most of the software which is running with
your current mailer (sendmail, /usr/bin/mail, etc.). It does NOT,
by default, use the variables specified in the config/*.mcr and
config/*.h file. You would be wise to look over the Makefiles for
AMDS *very* carefully, before committing yourself to this, and in
ALL cases, back up your mailer software so that if it doesn't work,
you are not without mail.

I learned this lesson the hard way!

Fred earlier said that pobbconf ``suggests some things that can be done in 
installing mail systems, but is not actually used as-is anywhere.''  This 
might be literally true, but last December it was used, as-is, for installing 
any changes to AMDS as it was installed at CMU.  Since then, the locus of 
control for AMDS may have shifted away from the copy of 
andrew/overhead/pobbconf used in making the X distribution, but the people 
doing the CMU installation started there.  Furthermore, I installed AMDS at 
transarc.com starting with the X distribution of andrew/overhead/pobbconf.


There are really two issues about what's getting overwritten.  AMDS makes 
direct use of sendmail or /bin/mail obsolete for your local system.  If you 
define RUN_AMDS_ENV in your site.h, the directories andrew/ams/sendmail and 
andrew/ams/mail will be built, and they attempt to overwrite or remove such 
files as /usr/lib/sendmail, /usr/lib/aliases, /bin/mail, and the like with 
stub programs that basically point to yet-unconverted programs or scripts that 
try to send mail the old way.  Unfortunately, as Sean (and others) found out, 
overwriting these programs with stubs can be rather premature.  (That's at 
least what I believe he meant when he said ``It does NOT, by default, use the 
variables specified in the config/*.mcr and config/*.h file''--that it removes 
and overwrites things other than what's under the value for BASEDIR in *.mcr 
or *.h.)  My apologies to Sean and whoever else has stumbled across this one.


The other issue is what gets overwritten from andrew/overhead/pobbconf, which 
never gets recursed-into by default.  There, as the instructions say, you're 
charged with specifying a lot of paths under which software will be installed; 
generally, this stuff is put in places other than under BASEDIR, but you could 
probably put it anywhere you wanted.  Many of the path distinctions are 
historical, and derive from the fact that at CMU, two fake user accounts are 
considered to be privileged as far as AMDS is concerned: a 
white-pages-building daemon and a mail-deliverer daemon.  Files in the ``home 
directories'' for these daemons were historically important for the purposes 
of running the WP rebuilding system or the mail delivery system. 
 Traditionally, these files weren't kept under BASEDIR at all.  In retrospect, 
they could have been installed under BASEDIR, and a separate program could 
have been invoked for doing the installations in other places, should that 
have been necessary.  But if you ever look at 
overhead/pobbconf/pobb-install.*, that's largely what that file is doing 
anyway.


I will still look into getting some kind of mpp distribution available.  You 
might want a ``package'' program also, though that's far easier to work 
around: you can take the package source files that overhead/pobbconf 
generates, and edit them into a shell script that initializes files on a PO/BB 
server machine's disk.

Subject: Individual disabling of backups after they've been globally enabled.
Cc: Info-Andrew-Bugs <info-andrew-bugs+@andrew.cmu.edu>, mar@ATHENA.MIT.EDU,
        jfc@ATHENA.MIT.EDU

I just discovered a little problem in using the nonexistance of the
BackupExtension preference to inhibit production of a backup file.
I just set a BackupExtension preference in our site wide global.prf.
Once it is set, it is impossible for a user's individual preferences
file to override with a null preference.  This is because, the null
value also means that none is set.  If none is set, no override can
happen.

Throughout the preferences code, a return value of null means the same
thing as "this variable is unset".  Rather than attempting to change
this, I added a new preference to buffer, "DisableBackup" which allows
the backup to be disabled.  I have tested this patch, but not
extensively.  I offer it as a suggestion for how this problem might be
solved.  (I had to solve it myself because I neede a fix for MIT by code
cut day...)

I am very new to this, so go easy. I was trying to use table (what other

failed silently. Now, for reasons I won't go into now, we can't directly
send postscript to our laserwriter on the andrew client, so I have
a shell script in my bin which does a /usr/ucb/rsh goanna lpr -Ple < $*
type thing to send it to goanna's lpr. This is probably the problem.
Can anyone give me a solution? While I have your ear, I am sure people must
have asked this one before, andrew's internals look so much like latex yet
we can't get it to throw out latex (troff ... yuck). Why did they do this?
are there plans to support latex/tex? thanks in advance
Oh the printing problem occurs with all utilities, eg help etc (as you
would expect ... same problem)

Both "mpp" and "package" were written by Russell J. Yount, formerly a 
programmer for CMU's "Andrew Systems Administration", now transformed into 
"Distributed Unix Computing Services". He was not working for the ITC, and he 
did not work for IBM, so I'm pretty sure CMU owns his code and could 
redistribute it if they wanted to .......


maybe Transarc has revised it in the version of "mpp" that they distribute; I 
don't know the details. (maybe I'm completely missing the boat and Transarc's 
"mpp" has nothing to do with Russell's original "mpp"?)


Although he now works for the University of Pittsburgh, Russell can still be 
reached as rjy+@andrew.cmu.edu if anyone wants to ask him what he thinks (not 
that it matters much :-)

What you can do is put something like the following in your preferences file ( 
or in your site's global preferences).


\example{*.printcommand: /usr/ucb/rsh goanna lpr -Ple -J%s

}
This will pipe what, by default, goes to lpr to that command, replacing the %s 
with the file name.  If this is going to be the default for your system, you 
could also put the following in your site.h file


\example{#define print_PRINTCOMMAND "/usr/ucb/rsh goanna lpr -Ple -J%s"

}
and recompiling the print module in atk/support.


\quotation{ andrew's internals look so much like latex yet

}\quotation{we can't get it to throw out latex (troff ... yuck). Why did they 
do this?

}\quotation{are there plans to support latex/tex?}


When this code was first written, troff was practically the only choice on 
Unix boxes.  There is work going on to get ATK to produce latex instead of 
troff, but it isn't happening at the ITC and I will leave it to the people 
involved to comment on if and when it will be generally available.

This is so embarrassing.  We seem to have "misplaced" our Volume 2 of the
Andrew Programmer's Manual.  You know, the part with ALL the methods in it.
I'm requesting a pointer for ftp of this volume, or the place in the source
code that it's supposed to reside.  We're kind of stuck until then.  Thanks
in advance.  (BTW, we don't even know where Vol 1 came from!)

Our news server was down, so I don't know if my previous questions ever got

I'm wondering if anyone out there has tried making an Andrew tiff data
object.  That is, an object that allows ez, et al, to use tiff image files.
The problem I see is with the lack of color support.  There has to be some
way to emulate the XCreateImage call in xtiff.  Any information out there?
I'd love to hear some ideas.

Subject: need help using creating menus with ADEW

Hi there.  Perhaps someone could help me out with a problem
I'm having creating menus under an ADEW created application?

I have an application which consists of an lset object with a group of
buttons, a tree/treev object and a text/textview object pasted into
it.  I want to override the default menu I'm getting in the tree/treev
object (one pane with 'Quit' in it (from the IM?)) with a menu of my
own.

I first tried using the standard menulist procedure described (on p.102) in
the ATK book to put up menus.  I couldn't get this to work under ADEW.
I then figured that the lset/arbiter/cel stuff was getting in my way, so
I read up on them and tried using celview_SetMenulist() on the cel that 
contained the treev object.  This didn't work either. 

Can someone tell me what the proper procedure is?

Also, while I'm asking questions: is ADEW "industrial strength" yet?  I
haven't seen any large applications written with it.  Should I be
using it or just doing it myself in ATK?  Is there someone out there
who wants to relate their experiences with ADEW?

Thanks,

The following code caused a compilation error in the call to 
textview_getdataobject:


\excerptedcaption{Excerpts from internet.info-andrew: 2-Apr-90 calling

\example{\quotation{--$enable class access

}\quotation{	selectionlen := textview_GetDotLength(textview)

}\quotation{	\bold{text := textview_getdataobject(textview)}

}\quotation{	stylesheet := text_GetStyleSheet(text)

}}
The difficulty is that calls to methods and class variables are NOT 
case-insensitive.  The proper call is 

	\bold{text := view_Getdataobject(textview)}


with the uppercase G in "Get" and lower case d and o because that is how the 
field name is declared in view.ch.  It is better to use view_ instead of 
textview_ because the declaration of dataobject is in view.ch.


With the wrong case, the Ness parser interpreted the call as a call on an 
undefined function, so the type was assumed to be marker.  That is why the 
type mismatch was flagged.

}The cel stuff isn't "getting in the way", it is just requiring you to use a 
different (and simpler) interface, since you are not creating your own view 
anywhere in the view tree.  Celview_SetMenulist() is the proper routine. I 
just created a simple test routine that overrides the Quit menu when an 
underlieing fadview has the input focus. At the top of my controller code I 
have the following. 


\example{/* user code begins here for includes */

#include <bind.ih>

#include <menulist.ih>

static void hello(v) 

struct view *v;

\{

    fprintf(stdout,"hello\\n");

    fflush(stdout);

\}

static struct bind_Description ttstBindings[]=\{ 

    \{"ttst-hello",NULL,0,"Quit~0",0,0,hello,"hello"\},

    NULL

\};



/* user code ends here for includes */

}
and in the initialization code, I have the following. 


\example{/* user code begins here for ttst_go */

\{

    struct classinfo *viewtype = class_Load("view");

    struct menulist *ttstMenus;

    struct celview *cv;

    ttstMenus = menulist_New();

    bind_BindList(ttstBindings, NULL , ttstMenus, viewtype);

	if((cv = celview_GetCelviewFromView(self->fadView)) != NULL)\{

    	celview_SetMenulist(cv, ttstMenus);

		celveiw_Repost(cv);

		\}

\}

/* user code ends here for ttst_go */}


If there is any chance that the fadview already has the input focus at the 
time, the call to celview_Repost(cv) will cause the celview's children to 
repost their menus, so that the celview can add the new entry.


Please get in touch if you have any questions.


\quotation{Also, while I'm asking questions: is ADEW "industrial strength" 
yet?  I

}\quotation{haven't seen any large applications written with it.  Should I be

}

As the creator of ADEW and the current manager of the ATK group, I am willing 
to state that ADEW is as supported and as  "industrial strength" as the rest 
of ATK, though it is a higher level interface than ATK, and, as such, may not 
be appropriate for some applications. I would also be interested in hearing 
about other people's experiences with ADEW.

going on....

I'm using the X11 version.  I just built  it, and for some reason, all
my cursors are  letters. All my background  patterns are weird, and the
demo stuff (like the letter(L) with the  animated CMU logo), which the
text  indicated was "the   round  ITC logo") have characters  where it
looks like some symbol should go. I'd bet  it's some simple mixup with
fonts, like icon12.snf, but ....

What am I doing wrong?

X11r4 andrew distribution, SUNOS4.0.3, sun 3/60, cc compiled.

The \bold{Adew Reference Manual} on page 3 says:


\subsection{1.2.8	Removing a child object

}The Cut button (displaying scissors) can be used to cut the selected child 
from an application. Alternately, the Cut menu option on the Arbcon menu will 
do the same thing.


\bold{WARNING: not all ATK parent objects support this option. As of this 
release, only text,lset and page are known to contain the necessary code. 
ATTEMPTING TO CUT CELS FROM OTHER OBJECTS MAY RESULT IN CORE DUMPS! Creators 
of parent views are advised to observe the child views they create and react 
correctly when they are destroyed.


}I came across something that I really really want to be able to cut out in 
\italic{Adew} and I can't. The \italic{object view} combination that I have in 
mind is \bold{text-panel}. I was wondering if someone would be willing to 
share the magic that needs to be put into panel (I presume) enable me to cut 
out a panel from a lset in Adew without producing a 9Meg coredump.


Thanks.

	There is apparently a bug in panel's finalize object routine.  I will make 
sure that a patch is sent out to fix this. In the meantime, there are two ways 
you can deal with the problem.


Fix 1.

	Create a new application file and use the arbcon to copy each inset (except 
for the text-panel) from your old application into the new one. Then just save 
the new file and delete the old one. This is the generic way of dealing with 
this problem and it can usually be done quickly and with a minimum of pain. 


Fix 2. 

***\bold{\italic{Warning, Entering Hack Zone}***

}
Use a non-ez editor (ed , vi, emacs, whatever) to edit the datastream of the 
application file and search for the following line

\example{
>VIEW< panel

}
and change it to 


\example{>VIEW< textview

}
Then, the next time you edit it with ez, it will come up with a textview view 
instead of a panel view, which can be easily cut with the arbcon.

It sounds like you are not picking up the icon fonts.  Make sure they
are installed, and make sure that no other directory on your font path
provides identically named fonts.  Some of the Open Windows fonts
conflict in names with the Andrew fonts.

Subject: How to make zip much more reliable.

I (and many others, no doubt) have had the frustrating experience of
trying to do close work with zip and having it seem to ignore or mis-do
the commands I specify.

I thought this was because of some terrible bug deep inside the system
that was causing mouse motion to be mis-processed.

It turns out that it's a preference that is set to a very different
default than my expectation:

ZipCreateTolerance

The default is 10.  This means that if I try to continue a polygon
within 10 pixels of the previous point, I can't.  I have just tested the
preference:

*.ZipCreateTolerance: 0

in global.prf, and zip is MUCH nicer to me.  Even tickling arcs is easier.

I strongly recomment that further testing be done, with an eye to making
zero the default value.

I am trying to build the Andrew system that is on the X11 r4 contrib section
from MIT.  I have an HP900/375 running HP-UX 7.0.  I am having problems trying
to build stuff in andrew/atk/basics/common.  There are problems with building
several ".do" files.  Specifically I get the following errors when trying to
build "region.do":





I believe that the stuff in overhead /class/machdep/hp_68k is erroneously
removing the necessary entries from the list it generates.  

Can any one help me?

HP has provided us with the updates to the R4 distribution that make it 
possible to build it under 7.0.  We are in the process of integrating those 
changes with the rest of the distribution and they should be available in the

I figured it out. Thanks to the people  who mailed  suggestions. As it
turns out, the andrew font dir had no  fonts.dir  file in it. A simple
run of mkfontdir was sufficient to make all the probs go away. I don't
know what happened during the make process. Perhaps I set up the imake
wrong. who knows.

Again, many thanks. Impressive.  Only thing  that bothers  me about it
all is that:

1. the mail  facility (apparently) doesn't  work with  normal mailers?
(ie. sendmail) -- For those who don't want the bells and whistles.
2. The format for multimedia docs isn't standard (but then, what is?).
I see the interleaf  converter, but  everyone around here  uses Frame,
and I'm sure  there's 10 or 15 other  doc packages  around. What about
MIF? or TIFF, or whatever its called?
3. The editors are NOT wysiwyg.
4. Reliance on extras like ditroff & friends  (which I don't have). We
do have TeX, etc.
5. The reliance on the AFS stuff for the BB's. We don't have it. Never
heard of it before.  Does it beat NFS?  Maybe  we at this  should know
more? We have over 200 machines on our network, and there  are several
networks around here.  How do I get  some data on  all  this?
6. No sound  standards. NeXT  has multimedia mail. Anything in common?
Wouldn't it be neat to be able to mail back and forth outside just the
X environment?


What I like:
1. In general, the idea.
2. The "widget" set. Handsome.
3. The documentation. Wow. It'll take a month to absorb it all.

Most of the complaints are well-taken.  Only two comments from here:


\excerptedcaption{Excerpts from internet.info-andrew: 17-Apr-90 The cursors

}
It should work fine with sendmail; that's how we use it at Bellcore, for 
example.    What problems are you having?

}
You can have bboards without AFS.  We do at Bellcore, and I know there's a 
similar setup at Bell Labs.  However, the documentation on setting up a new 
bboard system is very poor, to say the least.  Meanwhile, yes, you should 
check into AFS, which beats NFS by almost any measure.  It is available as a 
commercial product these days from Transarc Corporation in Pittsburgh.

I don't know how you compiled it (whit or whitout delivery), but AMS
works here with standard ucb-mail (i.e. sendmail), you have to use the
Andrew Setupfile (for more information: help setup).
This is our Andrew Setupfile (/usr/andrew/etc/AndrewSetup):

    AMS_NonAMSDelivery: yes
    AMS_AllowColonInSeparatingFrom: yes
    AMS_CheckAddressInSeparatingFrom: yes
    MessagesAutoBugAddress: pive@rucageo
    LocalBboardRoot: /usr/bulb/.MESSAGES
    DefaultMSPath: $MAIL:$LOCAL

I hope you will able to integrate AMS with yous mailer.

Subject: Color Methods change proposal

\begindata{text,270197460}
\textdsversion{12}
\template{messages}
The ITC is currently engaged in improving the color support of ATK. As part of 
this effort, we are considering changing some of the existing methods of the 
graphic class. The changes are detailed below. We would like to get a sense of 
how many developers, if any, would be affected by these changes before we make 
them. If you feel that your work will be adversely affected by these changes, 
please voice your concern.


These four methods exist now, as declared in graphic.ch:


\typewriter{\smaller{    SetForegroundColor(char *colorName, long red, long 
blue, long green);

    GetForegroundColor(long *red, long *blue, long *green);

    SetBackgroundColor(char *colorName, long red, long blue, long green);

    GetBackgroundColor(long *red, long *blue, long *green);

}}
The proposed changes are to reverse the order of the blue and green arguments 
in all of them, to correspond to the commonly used "RGB" term for this color 
model. Also, the \typewriter{\smaller{GetForegoundColor}} and 
\smaller{\typewriter{GetBackgroundColor}} methods would be modified to also 
return a colorName, if these colors are set using a colorName.


We also propose to eliminate the unimplemented 
\typewriter{\smaller{ColorPattern}} method, as it will not play a part in the 
new color scheme.



\bold{New Methods:}

Here's a list of the new methods we are adding, with some explanation. We 
welcome any input you might have on them.


\smaller{\typewriter{    SetFGColor( double red, double green, double blue );

    GetFGColor( double *red, double *green, double *blue );

    SetBGColor( double red, double green, double blue );

    GetBGColor( double *red, double *green, double *blue );}}


These four methods set and get the foreground and background colors, with RGB 
values expressed as real numbers between 0 and 1. They provide a more 
PostScript-like, and less X-like, interface. The colors remain synched, 
regardless of which set of methods you use to set them. Setting colors either 
way on a monochome display will invoke an algorithm to approximate the color 
with stippling. The existing fill methods will now accept a NULL tile 
argument, resulting in solid fills of the current foregound color.


\typewriter{\smaller{    DisplayClass() returns long;

}}
Returns a bitmask describing the class of the default visual of the display, 
allowing programs to special case monochome, and so on.

  

         \smaller{\typewriter{NPlanes() returns int;

}}
Returns the number of planes the display has, from which the maximum size of a 
colormap can be determined.


Not related to color, but just for good measure we are adding in these Line 
Style methods:


\typewriter{\smaller{    SetLineDash( char *dashPattern, int dashOffset, short 
dashType );

    GetLineDash( char **dashPattern, int *dashOffset, short *dashType );


    SetLineCap( short NewLineCap );

    GetLineCap() returns short;


    SetLineJoin( short NewLineJoin );

    GetLineJoin() returns short;}}

Subject: ZIP dies on a VAX


I've got atk (patch level 5) running on the VAX's here, and all is well
except for ZIP, which doesn't work at all.

If I run zip on a new (empty) file, I get numerous lines like

> ZIP Default Exception Handler -- Facility ''  Status '1'

to stderr, and the pallettes don't come up. Attempting to enter Brouse
mode generates more lines like this, and a core file.

I have no clue as to where to start looking, and as I say, everything else
pretty much works.

Any help would be appreciated.

Seems reasonable.  But it would be even more attractive to have a color 
object, so that Set and Get would have the form


\example{	SetForegroundColor (struct color *color);

	struct color *GetForegroundColor();

}
The color object would have


\example{	class color \{

	classprocedures:


	CreateRGB (double r, double g, double b) returns struct color *;

	FindRGB (double r, double g, double b) returns struct color *;

	FindOrCreateRGB (double r, double g, double b) returns struct color *;


	CreateHSV (double hue, double saturation, double value) returns struct color 
*;

	FindHSV (double hue, double saturation, double value) returns struct color *;

	FindOrCreateHSV (double hue, double saturation, double value) returns struct 
color *;


	CreateByName (char *colorName) returns struct color *;

	FindByName (char *colorName) returns struct color *;

	FindOrCreateByName (char *colorName) returns struct color *;

Right.  Only `color' objects would be used.

algorithm to approximate the color with stippling.

solid fills of the current foregound color.

Good stuff.

\quotation{Returns a bitmask describing the class of the default visual of the

}
Sort of X-specific, isn't it?

\quotation{  

}\quotation{         \smaller{\typewriter{NPlanes() returns int;

}}}
I've never been happy with this approach.  I'd add a class procedure to the 
color object, or perhaps add a colormap object, from which the number of color 
cells can be obtained, without reference to the number of display planes (too 
hardware specific).



\quotation{Not related to color, but just for good measure we are adding in 
these Line Style methods:

}\quotation{    GetLineCap() returns short;

}
\quotation{    SetLineJoin( short NewLineJoin );

}}}\quotation{\typewriter{\smaller{    GetLineJoin() returns short;}}

Sort of X-specific, but why not?


Thanks for giving us this visibility into the planning.

Here is a somewhat dated summary of my efforts to read netnews with messages. 
 I finally turned off the indexing daemon because it consumed too many cycles. 
 A stripped down system that knows how to read the active file is needed. 
 Something based on `nns' is probably the ticket.  I don't know that either of 
the patches given below are actually needed anymore.

\bold{Subject}: Summary of my efforts with messages/news so far


Here's a summary of my procedure so far, starting with your original 
instructions, and the two patches I had to make to AMS:


\quotation{\Bold{Date}: Wed, 17 May 89 12:45:14 -0400 (EDT)

\Bold{From}: Nathaniel Borenstein <nsb+@andrew.cmu.edu>

\Bold{To}: Bill Janssen <janssen%titan.sw.MCC.COM@mcc.com>

\Bold{Subject}: Re: news with messages


Here's what you do:


1.  Create a new directory that will be the root of the netnews tree, e.g. 
/usr/janssen/netnews/.MESSAGES/netnews.  Add the appropriate .MESSAGES root to 
your *.mspath preference.

}
[ I'm using \example{/usr/lib/news/.MESSAGES-news/bb}    -- wj ]


\quotation{2.  Create an appropriately-named symbolic link from that directory 
to the various top level netnews directories, e.g. .../.MESSAGES/netnews/comp 
as a symbolic link to the top of the "comp" tree.


3.  Create a file in the .MESSAGES directory called ".amsalien".  This is the 
magic flag file that tells AMS that the whole tree is an "alien" tree.

}
[ 3a.  Use cui to create an empty AMS index (.MS_MsgDir) file in some 
directory, by creating a new folder from cui or messages.  Copy this index 
file to every news directory.  Set up a daemon that will copy this file to 
every new news directory.  -- wj ]

\quotation{
4.  Set up a cui daemon that regularly scavenges the whole tree.  The right 
command might be something like:


loop -1 600 scavenge netnews recurse purge

}
[ I'm using the shell command:  \example{% cui}\example{ set level wizard \\; 
set bbdaemon on \\; loop -1 600 scavenge netnews recurse purge}


-- wj ]

\quotation{
(You may want to consult the cui help for info on the loop and scavenge 
commands.)


5.  If you want to use the master update file mechanism for faster checking to 
see which folders have new messages, you'll have to set up the master update 
files and related daemons; this is, I believe, documented elsewhere.  It is 
optional, but will improve the performance of the "checking for folders with 
new messages..." operation.

}\flushleft{
[ Haven't tried this yet  -- it amounts to running `cui rebuild 
/usr/lib/news/.MESSAGES-news' every night.  -- wj ]


}\quotation{6.  Bear in mind that you're the first person to try any of this 
on netnews.  The "scavenge" operation is the potentially dangerous one.  I 
advise that at first, you try it on a COPY of your netnews tree...


Please let me know how all of this works out if you try it, and feel free to 
ask me any more questions you might have... -- Nathaniel

}
[ But before you begin, fix two bugs in the X11R4 beta version of AMS, as 
follows:


\quotation{     The command \bold{loop} in cui is broken because the routine 
DemonLoop() in cui.c allocates

buffer space for the command buffer on the stack via an automatic variable 
(rather

than via malloc), and the routine GetNextCommand() in cui.c doesn't like 
commands

stored in buffers the address of which has the high order bit set. (Honest!)


This patch fixes it:


\typewriter{*** cui.c.orig	Thu Dec 14 18:37:48 1989

      \}

  \}

      \}

      cmd = StripWhiteEnds(cmd);

      while (TRUE) \{

! 	\{

! 	\}

!       sleep(Period);

      \}

}
63.  (in ams/libs/ms/rawdb.c)


     The MS scavenge operation only scavenges the first file in an alien 
directory,

because the routine CheckCheckLists() assumes that nothing in

AppendFileToMSDirInternal() steps on the buffer containing the filename,

and something does.


The following patch fixes this:


\typewriter{*** rawdb.c.old	Fri Dec 15 17:32:09 1989

There are still some missing pieces, such as being able to run FLAMES on news, 
and being able to post to the newsgroups.  There are too many folders 
(\quotation{Expose All} takes minutes); perhaps a better folder management 
scheme is needed [ running cui rebuild should fix this].  But all in all, it 
seems to work.

Anyone else out there still have a .hark_profile?

>1. the mail  facility (apparently) doesn't  work with  normal mailers?
>(ie. sendmail) -- For those who don't want the bells and whistles.

At CMU AMDS is probably used for most delivery, but I'm running it
against sendmail just fine.  The configuration is a little tricky, though,
and I'm stil very uncertain as to just what kind of locking my binaries
are doing.

>I see the interleaf  converter, but  everyone around here  uses Frame,

Be glad -- Interleaf is a nightmare.

>MIF? or TIFF, or whatever its called?

TIFF is only for images.  I'm not sure that MIF is.

>3. The editors are NOT wysiwyg.

Are any really?  You have to allow for the fact that windows can be resized,
plus the usual reasons of screen fonts vs. printer fonts, etc.

>4. Reliance on extras like ditroff & friends  (which I don't have). We
>do have TeX, etc.

You gotta rely on something.  If out put out PostScript, you're still
relying on PostScript.  Last I knew you could filter into a Scribe .mss
file, though.

>5. The reliance on the AFS stuff for the BB's. We don't have it. Never
>heard of it before.  Does it beat NFS?

Holy war time.  Unless AFS has changed radically since I was around, it
requires a local disk for workstations to use as a file cache.  It scales
well, but it is a pain to have to fetch the whole termcap file to see
the first few lines, for example.

>  Maybe  we at this  should know
>more? We have over 200 machines on our network, and there  are several
>networks around here.  How do I get  some data on  all  this?

I believe that some ITC and Scribe folks got together, called themselves
Transarc, and *sell* AFS now.

>6. No sound  standards. NeXT  has multimedia mail. Anything in common?

You can send mail with animation and images.  The "Welcome to Andrew"
message, for example.  I've never believed that sound was important
except to yuppies who buy car phones.

2. The format for multimedia docs isn't standard (but then, what is?).
I see the interleaf  converter, but  everyone around here  uses Frame,
and I'm sure  there's 10 or 15 other  doc packages  around. What about
MIF? or TIFF, or whatever its called?

murf
---------------------------------------------------------
As already mentioned, TIFF is a raster standard, not a multimedia standard.
However, ODA is a multimedia standard, and that is what the translators
you refer to deal with. Call up Frame and ask them for an ODA translator
for their format. (It actually might exist in a backroom somewhere, since
a number of gov't programs are beginning to adopt ODA in their requirement
specifications.)

\quotation{However, I would like to integrate netnews into the bulletin board 
system.  I looked at the documentation, and it was confusing.  I couldn't tell 
what depended on AFS and/or AMDS and what didn't.  I know there was some 
discussion a while back about doing this with \bold{.amsalien}, but 
unfortunately, I didn't save those messages.  And how about posting news from 
AMS programs?  Are there hooks to support that?  

}
\quotation{If it's not too much trouble, could someone who's done it 
successfully outline the steps you need to go through?  

}
Sigh... I guess I have to answer this one.  I don't want to answer it, because 
I feel guilty about it.  You can tell how guilty I feel by the fact that I'm 
answering in substantial detail...


At CMU, as most people have heard, AMS reads netnews.  However, it does this 
using some homegrown software (nntppoll, nntpxmit) that, while included in the 
Andrew distribution, is neither terribly well documented nor terribly 
well-suited to other sites.  The biggest problem with using this stuff is that 
it makes another copy of the whole netnews database, in Andrew format.  For 
sites that are already struggling to have enough disk space for a single copy 
of netnews, this is obviously a dismaying prospect.


When I decided to leave the Andrew project, I realized that I would soon be 
using Andrew at a substantial distance from the warm and comfortable bosom of 
Carnegie Mellon.  Suddenly I was newly motivated to look over the "bug reports 
& feature suggestions" list for things that would bother me more at a non-CMU 
site.  The biggest thing on that list was the absence of netnews support.  So 
I added the .amsalien feature with the express intent of using it to read 
netnews in its standard format.


Problem was, I didn't HAVE a standard netnews database to test it on -- at 
andrew.cmu.edu, there's only one copy of the database, and it is in AMS 
format.   So I added the code and debugged it in-the-small, and intended to be 
the first guinea pig for it when I got to Bellcore.


Now comes the part I feel guilty about:  I've been here about 9 months, and 
I'm having so much fun and keeping so busy with other stuff that I just 
haven't gotten around to hooking up AMS to netnews.  (Guess what?  I barely 
even MISS netnews...)    I still intend to do it eventually, but I honestly 
don't know when I'll get to it, and it isn't something Bellcore will want me 
to spend a lot of time on, of course.  Meanwhile, though, I'd be more than 
happy to provide advice and assistance to any brave soul who wants to be the 
guinea pig instead of me.  (Actually, a couple of people have tried, but I'm 
not sure how far they've gotten, and I won't give their names out here...)


The bottom line is that it shouldn't be very hard, but that there will 
probably be a small amount of debugging to be done before it all works 
smoothly.  I'll try to get to it one of these days, really...  -- Nathaniel

Since you bring up netnews, there are alternatives to AMS for netnews.


What I do is to run \typewriter{readnews -p} as a cron job every night, and 
have a single file containing the day's news put into my rje.  I have a 
package that provides formatting and commands that make it easy to read 
(next/previous article, next/previous newsgroup, etc).  Then I just ez the 
file.  Is is \underline{so much} faster than AMS.  I can scan through an 
avarage of 500K of news in less than 20 minutes.  I bind "next article" to a 
kay, and I can hold it down and skip through several articles per second.  It 
also works with "table of contents", for quickly scanning the titles.  It is 
easy to save articles, using cut/paste.  Has anyone else tried this approach ?

The first Andrew Toolkit User Group (ATUG) meeting will be held on Friday, May 
25, 1990 at the San Jose Convention Center, San Jose, California. It is being 
held in conjunction with (and immediately after) the Xhibition '90 conference. 



\indent{ATK, the Andrew ToolKit, is an extensible user support environment 
which provides an editor, a shell interface, a system status monitor, 
electronic mail, and numerous applications. The environment is not monolithic: 
users can choose among the ATK tools which best satisfy their needs and can 
continue to utilize any other tools as they desire. Since ATK is extensible, 
sites can easily add other applications to the environment without the effort 
of development from scratch.


As a user-interface toolkit that runs under X11, ATK provides a 
dynamically-loadable object-oriented environment wherein objects can be 
embedded in one another. In addition to containing multiple fonts, text can 
contain embedded raster images, spreadsheets, drawing editors, equations, 
simple animations, etc.. These embedded objects could themselves contain other 
objects. These resulting multi-media documents can be edited, printed, or sent 
in mail messages via the Andrew Mail System(AMS). With the toolkit, 
programmers can create new objects that can be embedded as easily as those 
that come with the system. 


The X11-R4 release also includes an interface building system that facilitates 
the creation of multiple-object applications (Adew), an object-extension 
language (Ness), a hypertext-like link facility(Link), a charting 
facility(Chart), a directory browser (Bush) and enhanced printing support that 
includes the automatic generation of tables of contents and indexes. The ATK 
source is distributed on the X11 tape in contrib/toolkits/andrew.

The following talks are currently scheduled:

Please forward this.


The claim


"...the number of planes the display has, from which the maximum size of a 
colormap can be determined."


is false.  The number of planes does not determine the colormap size.  There 
is a field in the visual structure which says how many colormap entries there 
are (and, importantly, whether they are read/write).  Real displays exist 
where ncolors != 2 ^ nplanes.


It is also not accurate to assume that a pseudo-color visual with n bits per 
pixel must have n bits of resolution for each color.  The megapel, for 
example, has 4 bits per color and 8 planes.  Some applications will want to 
use stipple fills to simulate 8 bits of color resolution.   There should be a 
way to request that stipple patterns be used or not with \italic{any} type of 
display, color or mono.  For example,


	SetFGColor(double red, double green, double blue, double res);


where the added argument "res" is the desired color resolution.  Examples: 0.0 
= exact (use stipples in all cases where the hardware has insufficient 
resolution),  1.0 = use whatever the display provides naturally (never use 
stipples), .125 = use stipples if the display provides less than 3 bits 
resolution per color, etc...

It seems the "open comment" period on the color proposal has run its course, 
so I'll quickly respond to what was posted.


\excerptedcaption{Excerpts from mail: 19-Apr-90 Comments on Color Methods c.. 
Bill Janssen@parc.xerox. (2964+0)}


\quotation{But it would be even more attractive to have a color object}


I don't think that colors deserve promotion to full object status. 
Functionally, they seem at home in the graphic object, and probably shouldn't 
be treated much differently than line styles, or transfer modes...


\quotation{	CreateHSV (double hue, double saturation, double value) returns 
struct color *;

}\quotation{	FindHSV (double hue, double saturation, double value) returns 
struct color *;

}\quotation{	FindOrCreateHSV (double hue, double saturation, double value) 
returns struct color *;}


Are there any plans for X to support an HSV color model? How about CMYK? 
Currently, we'd have to transform these to RGB. If the values are specified 
with floating points, this all starts to get very expensive.


\quotation{	CreateByName (char *colorName) returns struct color *;

}\quotation{	FindByName (char *colorName) returns struct color *;

}\quotation{	FindOrCreateByName (char *colorName) returns struct color *;}


The by-name color specification is very X-specific. We're keeping the support 
we have for it now for backward compatibility, but it shouldn't be propogated 
beyond that. Personally, I think people should be discouraged from asking for 
"burlywood" or "LemonChiffon3" :-)

\quotation{\quotation{Returns a bitmask describing the class of the default

\quotation{Sort of X-specific, isn't it?

}
In addition to defining symbolics for the six display classes defined by X, 
I've put in the symbolics \typewriter{\smaller{graphic_Color}} and 
\typewriter{\smaller{graphic_Monochome}}, which are or'd into the mask as 
appropriate. More could be added. You can extract as much or as little detail 
about the display as you want.

\quotation{I've never been happy with this approach.  I'd add a class

the number of color cells can be obtained, without reference to the number of 
display planes (too hardware specific).

Fair enough. The whole colormap business itself is hardware specific, and 
ideally we need a way to allow an object or application to use a large number 
of colors without having to deal with colormaps directly.

PostScript has direct analogs to all of these line style operators. It seemed 
like something of a consensus.

This certainly deserves some consideration. To some extent this can be done 
now, as the fill methods still accept a tile argument (which is now actually a 
stipple argument).


Thanks to Bill Janssen, Bill Cattey,  and John Carr for their input (more is 
always welcome).

}
There are some interesting operations that could be performed on colors, from 
retrieving their bitplane description, through finding an `inverse color', to 
doing name->color and color->name mapping.  At the very least, this offers us 
a chance to package the three RGB values, and any possible name.  Referencing 
through a color object also allows the possibility of doing colormap 
management in a sophisticated way that is much clumsier to do with the current 
`graphic' model.  I don't think I'd worry much about `promotion to full object 
status'.  In an OO toolkit, only the most trivial things (of which color is 
not one) are \bold{not} objects.


\quotation{Are there any plans for X to support an HSV color model? How about 
CMYK?

}\quotation{Currently, we'd have to transform these to RGB. If the values are

}
Both might be useful.  The expense only comes in when converting (on the 
function calls that explicitly reference the values).  Presumably the internal 
representation would be some suitable form, such as RGB.  Since the values are 
hidden in a color object, the conversions don't happen too often, and it winds 
up being not expensive.


\quotation{The by-name color specification is very X-specific. We're keeping 
the

}
Actually, color naming is a very reasonable, and fairly widespread, thing to 
do.  The problem is that the current X11R4 scheme for mapping colors to names 
and vice-versa is brain-damaged.  We use an algorithmic method for doing this 
at Xerox, which allows for 9 color names, and modifiers such as "dark", 
"light", "very light", etc.  It also will generate an appropriate name for any 
arbitrary RGB triple.  This kind of color mapping is \bold{much} more useful 
than any system of number triples, for use by people trying to select a color 
for common applications (backgrounds, etc.)  Note that the current X11R4 
scheme is not part of the X spec, and there is a possibility that we may be 
able to junk it and put in a reasonable scheme.  I might be able to provide 
code to do this, if you'd like it.


\quotation{>> Not related to color, but just for good measure we are adding in

\quotation{> Sort of X-specific, but why not?

Yep.

Subject:  Chaining menus and keybindings

I have two objects (A and B) where B is a subclass of A. Both define
menulists and have keybindings.  To get the full list of menus for B, I
chain the menus of A before the menus of B using
menulist_ChainBeforeML(B,A,A)

The menus appear correctly and keybindings for B-specific functions are
active but keybindings for functions on the A menus are no longer active.

Any suggestions?  Is there a better way to do this?
