If you want to get fancy, I might want to allow window dimensions to be specified at the time they are opened. I agree that being able to resize windows is nice, but I this is a fairly serious hit in terms of client complexity.

I don't think users would like to waste the power of bit-mapped workstations for such simple use, though. X was developed as a way to implement portably the kinds of applications that were already being run on Macintoshes, Suns, Lisp Machines, Xerox workstations, etc. The networking part was presumably a response to the problem that applications often need to run on computers that are a long way from the user (e.g. on a machine at some remote supercomputer center). > I rather suspect that this windowing system could be written to be >terrifyingly fast, and to consume negligable resources.

I don't think "image processing and animation" people would consider X to be a satisfactory solution to their graphics problems either! Let's face it: X was not designed with high performance graphics in mind. Look at the colormap fiasco, and the fact that every call to the X server is effectively a context switch. You just can't make good graphics code work under such poor conditions.

With the advances in dynamic linking a graphics server could also allow compiled code to be used, dynamic protocol extensions with the speed of compiled code. Main disadvantage compared to an interpreted language would be the increased chances of crashing the graphics/windows server but there could be ways around that with more sophisticated memory management on a per process basis.

This sounds a lot like NeWS does'nt it? NeWS actually has some good ideas in it; I would not dispose of it in a single statement like that. However, I don't think the answer to X is NeWS. But it's clear that if you nail your window protocol in stone (as X does) and that protocol operates at a very low level (as X's does) then the bottleneck for high performance graphics will be at the network/protocol level. If you do not allow dynamic reconfiguration of the window system, then every time you need to add a feature to the window system, you have to recompile the window code. This may or may not be an acceptable solution for you. I don't think it is. The interpreted language I have in mind is not PostScript. The language that is interpreted (or compiled on the fly for performance) should be "safe", i.e., it should not be possible for any single client to starve the resources of the window system, or to cause the window system to crash. If you do not use a "safe" language, then either 1) you will have to put up with the above 2 faults, or 2) you will have to write a window "kernel" that manages client processes in a protected environment with separate address spaces etc. The latter solution implies some fancy hardware, and I would like to see this window system written for all sorts of hardware, e.g., X terminals, or as user processes under Unix. -- To reveal art and conceal the artist | Byron Rakitzis, Texas A&M. is art's aim. -- Oscar Wilde. | byron@archone.tamu.edu

>Gee... This sounds a lot like NeWS does'nt it?
NeWS is a pretty cool idea, but I just can't appreciate adding
PostScript to a network-based window system. Before everyone jumps on
me, let me explain:
do an "lpq" on a machine with a few PostScript printers.
PostScript can produce spiffy images, for sure, but it's just
too easy to produce 100K worth of glop to print a page. The idea of
*THAT* as the imaging model behind my window systems makes me afraid,
very afraid. *USUALLY* I realize that having PostScript in the window
system is a savings, but you have to make sure that your applications
are not stupid about doing the PostScript equivalent of bells and
whistles.

This is one reason why most well written PostScript code downloads routines to the printer to reduce the bytes transferred. Writing efficient PostScript is not trivial. But at least you have that option. There is another advantage of the Stencil/paint model over the raster-op model: It is possible to pipeline the rendering, and even render in parallel. -- Bruce G.

You can make the same assertion about any language. Frugality is a virtue I agree, but using PostScript as an imaging model does not instantly turn you into a glutton. It's really a pretty reasonable language as interpreters go. I do agree with you though that there is some pretty lame postscript code which is output by some applications.

It probably doesn't do very much, but people seem to think it does it reasonably well. NeWS seems like it uses the right model, but people say it's really too slow and big to build terminals out of. And perhaps the language is too awkward; postfix if's are hard to read. As one who threw many logs onto this fire, I suppose I should reveal my purpose. One of them was to simply carp about the trials and tribulations I experienced when I attempted to implement an X protocol session recorder and playback program. During this, I learned many nasty things about the protocol. You could argue that it was not designed for this purpose, and strictly speaking, it was not. However, truly robust software often finds uses for which it was not designed. But I suppose my real purpose in bashing X, just like my bashing on NFS, is to warn people who don't really know better against following along blindly with the crowd. What I am after is for people to examine the issues, to look beneath the surface and consider the issues. To those who have done that and still support X, well, someone has to work on it.

I think that depends on the toolkit and development environment. Using tNt 2.0 and DevGuide, you can develop an application interactively, and then link in the toolkit without writing any PostScript at all, I believe. If you want to modify one of the widgets, you have to get into PostScript programming, but it's Object Oriented, so that helps. I agree about the language. The problem is parsing code like foo bar blatz mumble tilderoll You have to know each operator and how many items it pops/pushes off the stack.

I think that this is a trap, a typical Computer "Science" sort of pitfall. All your college professors will tell you about separation of policy and mechanism like it is some sort of manna from heaven. In the area of user interface this is, in my opinion, the worst possible thing that could be done. It is worse than having a bad, but consistent, user interface. Think carefully before you flame me - think hard about the Mac. The reason that *users* like the Mac is due, in part, to the consistent look and feel of the user interface. You may not like it, but you remember how it works. X blew it by handing out all that mechanism to developers. It would have been much better if they took a little longer and came up w/ the same set of functionality that the Mac (even the early Mac) had. Then all the apps would look the same, work the same. The toolkits were only a weak attempt. What X has done is similar to providing the source for libc and telling you to write ls. Every implementation of ls has different options and a different look and feel *to implement the same function*. Most bogus. --- Larry McVoy, Sun Microsystems (415) 336-7627 ...!sun!lm or lm@sun.com

That's fine for research, but for people who are more interested in USING the window system it's a loss. Also, it hurts flexibility in style and policy if you're working with existing code: if the communication between the client and the server is "open a text pane yea characters high and so many characters wide" then you can have that be an Open Look, Motif, Mac, PM, or any other UI text pane simply by changing the server: and all the apps will automagically change.

I believe the "..." was something like, "would consider a bunch of xterm windows to be usable". Most of our real-time animation work is generally done on frame buffers directly connected to the Connection Machine system. However, the CM graphics library is generic -- it can display on a directly-connected frame buffer or a networked X display. Since CM frame buffers are not as common as X displays, the developers generally use X output during development, and use the CM display for final, realtime runs. The general point I was making is that many people who use X *need* multiwindowed graphics, so a protocol that only provides a bunch of text windows is nearly worthless to them. -- Barry Margolin, Thinking Machines Corp. barmar@think.com {uunet,harvard}!think!barmar

X was NOT designed to provide a user-interface. One of the goals of the original design WAS separation of policy and mechanism. So saying "X did it wrong" is incorrect. What they set out to do they achieved. However, later, X started being used for something else - A commercial standard to build distributed application interfaces with. Why? Because of interest from the big computer vendors (HP, DEC etc.) in the mid-80's. For various reasons NeWS wasn't *commercially* acceptable, they needed something to counter it straight away and so they pushed X. Now, In the commercial world it makes sense to have consistent user interfaces etc. so the direction of X changed. I have been programming in X for a long time and I can attest to its change. Release 10 didn't even have a toolkit! Now you have too many! Will X ever be as good as something designed from the ground up now. No! But that is the penalty of retro-fitting something and the march of technology. >Think carefully before you flame me - think hard about the Mac.

Well, yeah :-) I agree with them, though. It *can* be very useful: I'm working on an X application right now that makes use of two home-rolled widgets. They plug right in to the toolkit and I can use them just like any other widget; if all the UI components were implemented in the server this would be much more difficult to do. >Think carefully before you flame me - think hard about the Mac. The reason >that *users* like the Mac is due, in part, to the consistent look and feel >of the user interface. You may not like it, but you remember how it works. No flames; I think the Mac is a great piece of work. But X had different design goals -- a consistent UI was explicitly *not* a consideration. The Mac does some things better than X, but vice versa as well. >X blew it by handing out all that mechanism to developers.

Motif apps under X are *just* as easy to use as MS-Windows apps, and Xt programming is considerably easier than Windows programming. Given a decent toolkit (and I'm not claiming that Motif is any more than decent; "good" would probably be stretching it) you can get a consistent UI that functions well. And, perhaps more importantly, under X you're not stuck with Motif (or OL, or Xaw, or whatever.) --Joe English jeenglis@alcor.usc.edu

The spec was right for a research system. It was, however, quite wrong for a commercial system. The problem isn't X, it's all the lazy manufacturers (and customers) who are using X outside its design goals. I don't care about the politics. I just want something that works without multiple megabytes of duplicated effort. Commercial X is like multiuser DOS: a horrible waste of resources.

Barnett barnett@crdgw1.ge.com uunet!crdgw1!barnett You could always define a couple of postscript "commands" which do nothing, e.g. /|- {} def /-| {} def and then mark things like this: |- 100 50 8 [1 0 0 -1 0 900] {<00>} false 3 -| colorimage Since all of the paren and brace type characters in PostScript are self-delimiting, you can't use them and are therefore forced to go to strange 2-character combos like the ones I suggested. You mentioned in an earlier message that you'd prefer prefix notation, and I think that would be possible if you defined -| properly and used the literal name (e.g. /colorimage) rather than the executable form. Youq should probably stick to postfix notation, however; defining -| so you could put the "colorimage" behind the operands would be messy to program and pretty slow.

But would everyone use it? There would need to be a large number of tools to make this popular. Like - positioning the mouse on the first bracket and hitting a command key that executes the commands within the bracket. (Like lisp). And having double/triple clicks expand fill the brackets. Then drag, copy and drop the code from one routine into another, call up a parser to check for the proper number of parameters. (e.g. selected text takes two parameters as input and generates 3 items on the stack.) You would also need some code to read a PostScript/NeWS program and generate the proper nesting of brackets. Now there's an interesting idea! This would tell you which commands consumed data, and which ones generated data. It would indicate nesting depth, and might go a long way to making NeWS easier to use. Let's extend the syntax a little. Maybe |- is a bracket indicating there is the same number of operates on the stack as the matching -|. If you have a procedure that takes three parameters, and consumes them all, use a different character. Perhaps |+++ to go with -|? > You mentioned in an earlier message that you'd prefer prefix notation, I wouldn't say it's the prefix part that is important. It's the clear indication of data flow that I like so much, and vanilla PostScript lacks. If NeWS was extended to have this sort of "syntactic sugar" without penalty, and the tools were added to make this usage desirable, it might be easier for people to pick up a random piece of code and follow it without memorizing AHEAD OF TIME the input/output of every procedure/command used. -- Bruce G.

Since this discussion does not pertain to unix internals or NeWS per se, I've directed followups to comp.lang.misc.] > Sometimes white spaces are detrimental. Hear, hear!, or Here, here!, or something! White space can be cheap, but it's rarely free. Horizontal whitespace is typically cheaper than vertical whitespace because almost all fonts are taller than they are wide. That is, there are more units of space available across the page than down. The use of whitespace must be weighed against the amount of code visible at one time, because scrolling around is as much a detriment to readability as too much or too little whitespace. Code is only written once. After that, it's a matter of staring it down to find out what/how to modify it. So, after the initial heavy editing, give it a beautifying pass. Eliminate a lot of unnecessary whitespace. Comments kind of fall in the same category. Never comment in-line that which is obvious or self-documenting. It's a fairly common practice to put atomic operations on seperate lines without even considering the operations surrounding it. I think it's better to put an single _semantic_ operation on a single line if it's reasonably short. I could spout more blather here, but I'll hold off for now. Here's a few things I usually do: 1. Within expressions, I like to use whitespace to indicate operator precedence. For example, I'll write "1 + 2*3" instead of "1 + 2 * 3", or "1 2 3 * +" instead of "1 2 3 * +". 2. Rarely will I devote an entire line to a mere grouping operator. For instance, I'll take the left over the right any day. /foo /foo {add} { define add } define 3. An example of putting a semantic operation on a single line: ... /* `cat' F to stdout */ { int c; while ((c = getc(F)) != EOF) putchar(c); } ... as opposed to ... /* `cat' F to stdout */ {int c; while ((c = getc(F)) != EOF) putchar(c);} ... I concede that less-compressed versions of the second form are easier to read. But this is such a trivial operation that the lack of whitespace does not impair its readability enough to justify adding more.
