[9fans] troff diversions
I think of myself as pretty proficient with troff, but I never get diversions right. One fairly useless task I set for myself was to write a smart quote macro. By that I mean that I want the macro to put the quoted text into a diversion, check how many lines the quote would be when formatted as a block quote, and then output a block quote if the number of lines is >= block-quote-threshhold or output an inline quote if it's not. Actually this is not so useless if you are writing something that may or may not be published in a variety of places that have different page layout conventions for block quotes, and you're a lazy person who doesn't want to make adjustments to even the rare borderline case by hand. Do you see what I have in mind? Any ides on how to achieve it? Thanks. Greg
[9fans] (no subject)
[acme.dump bin/ devel/ doc/ guide lib/ sys/ text/ tmp/] Subject: eqn and unicode I noticed that sometimes my troff-related questions don't generate much interest. I hope they aren't considered bad form, because I am curious about another thing. If you write the eqn-word for a greek letter, "GAMMA" for example; eqn passes the unicode character (the output of Alt-*G) to troff. If, on the other hand, you type Alt-*G in eqn, it passes `"\f2Γ\fP' to troff, thus producing, by my lights anyway, a nicer looking character. I was just wondering if this was intended as a way to give people both a roman-greek letter and an italic one, or if it was intended to discourage the use of eqn's letter names in favor of unicode, or if it just sorta happened. Perhaps none of the above. Anyone know? My problem is that I developed the habit of using eqn letter- words, and the output isn't very nice. (Yes, I know I can define GAMMA %"\f2Γ\fP"%, but I'm still curious.) Thanks. Greg

Hmm. I submitted a patch so that fonts would apply to resword
rather than making it so that they don't apply to greek letters,
and I'm not even sure I did that right.
diff -c /sys/src/cmd/eqn/text.c /usr/gp/sys/src/cmd/eqn/text.c
/sys/src/cmd/eqn/text.c:83,89 - /usr/gp/sys/src/cmd/eqn/text.c:83,90
else if (t == TAB)
p = "\\t";
else if ((tp = lookup(restbl, p1)) != NULL) {
- p = tp->cval;
+ sprintf(cs, "\\f%s%s\\fP", ftp->name, tp->cval);
+ p = cs;
} else {
lf = rf = 0;
lastft = 0;
Now I don't know what's right. What if, for example, you
use "gfont H"? Shouldn't that really make Γ get passed to
troff as "\fHΓ\fP"?

[9fans] eqn and unicode -- Again
I should probably just drop it because I reveal my ignorance when I post, and erik is the only one who has shown any interest, but ... I guess what I want is for eqn to sort of immediately convert GAMMA to Γ and then go about its business with Γ, as if it never saw the word GAMMA, got it? So, I was looking at eqn -d to get some more feedback and it seems that a user definition does that. Here's some output. cpu% eqn -d ... eqn version Oct 24, 1991 .lf 1 - .EQ .EQ define Gamma %Γ% . lex token = |define| . name Gamma defined as Γ Gamma . lex token = |Gamma| . found Gamma|=Γ| . lex token = |Γ| . 57346text: S11 <- \f2Γ\fP; b=0,h=1,lf=2,rf=2,ps=10 .ds 11 "\f2Γ\fP cpu% eqn -d ... eqn version Oct 24, 1991 .lf 1 - .EQ .EQ Γ . lex token = |Γ| . 57346text: S11 <- \f2Γ\fP; b=0,h=1,lf=2,rf=2,ps=10 .ds 11 "\f2Γ\fP Of course, I don't know if the treatment is the same in other contexts, but I'm wondering if a simple solution is to make gktbl and treat it like deftbl in lex.c instead of like restbl in text.c.

[9fans] Ken's FS: WORM Superblock read failed
Hi, I've been messing around with setting up a Ken's file server with old hardware that's accumulated over the years. Yesterday, I configured a file server with two IDE drives as ch0fh2. The setup seemed to go OK, but one of the last things on the screen before it brought the server up is in the subject line: WORM Superblock read failed. It also said something about block 2 (I know the numeral `2' was in there). When I booted this morning and let it go through the whole process, I got: tag = Tnone/0: expected Tbuck/2697 -- flushed (2697) panic: cwinit: ??? tag c bucket (Embarrassing. The "???" indicates where I can't read my own handwriting.) Any insight would be appreciated. Here's some more setup info: Motherboard is ECS L4S5MG with SiS 650/961 chipset Hard Drives are both Western Digital WD800JB (80G ATA drives) The kernel is 9fsfs64 from /sources/extra/kensfs.tgz. I don't know if Erik's fs has mods that are relevant. I haven't tried his contrib version yet. Thanks. Happy long weekend to those of you who have one. Greg
[9fans] PCI SATA Controller Cards
On a file-server related note, I almost feel committed to SCSI drives because I have a nice Tekram controller. However all of my drives are so old that I'm suspicious of them and buying new SCSI is expensive. It looks like I could switch to SATA controller and drives for less money than a couple of new SCSI drives as long as I don't have to spend hundreds to get a decent SATA controller. Anyone have any recommendations for a PCI SATA controller card that will work with Plan 9? Thanks. Greg
Re: [9fans] Ken's FS: WORM Superblock read failed
I didn't try recover, but since the config I really want is a partitioned
one like you suggest, and the errors I reported didn't make anyone
immediately think "dying hard drive"; I think I'll try getting your (Erik's)
fs from contrib.
I assume I can do something like this:
Put the two hard drives destined to be on the file server on my existing
fossil-only machine (I have a hard drive with that somewhere from the last
few days of experimentation).
Diskpart and diskprep those drives with, for example, 9fat, cache, and worm
on the drive destined to be h0 on the server and 9fat, other and worm on h2.
Using some appropriate sizes (approx 10% of disk size going to cache and
other with h0."worm" and h2."worm" the same size for mirroring).
Put 9load, plan9.ini, a kernel from fs on h0.9fat (Something missing? I
guess I just want to emulate what pc/bootfloppy would do for me, but I want
to copy those things to h0.9fat.)
Move the disks to the file server, boot, watch everything come up just fine,
and config something like:
filsys main cph0."cache"f{ph0."worm"h2."worm"}
filsys dump o
filsys other ph2."other"
I'd appreciate it if someone would let me know if I'm way off base here.
Otherwise, I'll probably give this a shot this afternoon or tomorrow.
Thanks.

Re: [9fans] Ken's FS: WORM Superblock read failed
Thanks Erik.
Yeah, the "f" device is just a consistent brain tic for me. Once upon a time
I thought for some reason that "f" always went with "c" unless you were
using a real jukebox, and now I can't seem to get rid of that
misapprehension when I write my configs.
I used "h2" because I intended to have the drives on separate controllers.
Are you saying it should be "h1" even if there is no primary slave, or are
you recommending that I put the drives on a single controller?
Getting optimistic about trying this.
It seems to me from my lurking around the groups that Erik is almost
single-handedly keeping Ken's FS alive. I would just like to voice my
appreciation for that.

Re: [9fans] native lbl, long text in troff, bold italics in eqn
I think you would have to use two passes of troff. The first pass would generate the info you needed to define the crossref macro. For example: .NH 2 Middle of Paper .LP .tm crossref: .if "$1"middle" see sec. \*(SN I have the label 'crossref:' in case you are generating definitions for several macros, and you want to grep the standard error to treat different lines in different ways. If you're using -mpm, for example, and you like running heads that change with section number changes, you need to use a method like this to define a running-head macro. If crossrefs turn out to be the only things that need this treatment, you can obviously leave the label out. Do a pass with troff -ms mypaper >[2]crossrefs. So crossrefs will look like .de CR .if "\\$1"middle" see sec. 3.7 .if "\\$1"differentsection" see sec. 7.2.6 . . .. Then read in crossrefs on the next pass, and all of your refs in the doc like .CR middle .CR differentsection should work. Putting thought into a text processing mkfile is probably worthwhile here. Although it's another example of bibliographic references, Russ Cox once posted some scripts using rc, awk and a mkfile that used this two pass idea. It would probably be worth looking at his example too. It's quite brief. http://groups.google.com/group/comp.os.plan9/browse_thread/thread/76ff0d3dc3c49e59/03bfa13f60f56900?lnk=gst&q=rsc+refs#03bfa13f60f56900 I think this is roughly right; I haven't used troff in a while.

Re: [9fans] troff macro II
Typing from phone so I'll be brief.
Just put the header at the bottom of the page and pipe the .ps output
through sed to change the vertical position.
I found this easier than moving back up the page in troff.

Hello 9fans,
since in the previous thread started by me ('troff macros for

producing wanted headings, I started experimenting, but so far has not
been quite successful.
Since text to appear in my headings is to mirror section names, like
'1.2', and a beginning of such a section appears somewhere lower on a
page---definitely below the page heading---, I must create a page
heading just after the very page is filled, i.e., as I feel, the
heading could actually be produced when the ms .BT macro (usually used
to typeset footings) is called. So I naively tried to redefine the .BT
macro, actually, by just appending 4 extra lines:
.de BT

[9fans] Rio windows size and location
Here's the summary for the window command in the man page. window [ -m ] [ -r minx miny maxx maxy ] [ -dx n ] [ -dy n ] [ -minx n ] [ -miny n ] [ -maxx n ] [ -maxy n ] [ -cd dir ] [ -hide ] [ -scroll ] [ -noscroll ] [ cmd arg ... ] If I do window -r 200 200 1000 900, I get the same result as window -minx 200 -miny 200 -maxx 1000 -maxy 900, which, frankly, believe it or not, was not what I expected. Given that -r allows one to specify the exact corners of the window, the result I expected, and would like, from the second form is just to create a rectangle on the screen, smaller than the screen size, to which the new window that opens is confined. So, my thought was every time I execute the first form, I get a new window of that exact size and location right on top of its predecessor, while repeated executions of the second form give me new windows of the default (600x400?) size but contained within the bounding box defined by me. The reason this came up is that I have a wide monitor, and I find myself moving windows to the center (as if it's a chore to look to one side or the other!?), so I decided to open clock, winwatch, stats along the right side of my screen (about 1520,0,1680,1000) and open new windows with the restriction -maxx 1520. For example, "window -dx 800 -dy 800 -maxx 1520" means give me a window that size anywhere you want as long as it doesn't go farther right than 1520. But, as I've already suggested, that command doesn't have the expected effect. Actually, just clicking on the window command I wrote resulted in this window (from wloc): "window -r 112 112 912 512". Anyway, the point is I started looking at wctl.c to see if I could get the behavior I want. I just thought I would ask if this is a stupid idea; or if it has already been done, and there's a way to get the effect I want that I'm missing. Thanks. Greg
[9fans] Rio windows size and location
Sorry for the self follow-up, but it did just occur to me that a simple solution is to start a new instance of rio within a window withe the boundaries I want, then, obviously, all subsequent window-openings will take place in there. D'oh. Greg
Re: [9fans] Rio windows size and location
I know that this self-conversation is getting silly, but I thought I would report that, as far as just starting a new rio, the winwatch that I'm trying to keep uncovered doesn't show windows opened in the new rio, sort of defeating the purpose. So, I guess I'm back to the original question. Now, I promise not to post again for at least 24 hours or until someone replies with a question directed to me! Greg
Re: [9fans] CPU Server Wiki, auth/keyfs, and password for the machine.
Thanks Russ for the typically thoughtful and informative reply. You are perhaps the most valuable resource on any mailing list anywhere. There ought to be an award or something. The reason I ask is that I missed that step the first time I tried to set up the CPU/Auth server, but I've since gone through it all again carefully more than once, and I stll get "connection rejected" with my Ken's file server. (Yes I know fossil/venti is the current standard, but what can I say, I'm, perhaps irrationally, or at least non-rationally, attached to the old file server.) The problem is, other than going through the Wiki and 9fans archives, which I've done, I don't have any notion of how to find out where I went wrong. I successfully set this up in the past. I did remember to add IL back to pccpuf, and, as I said, I followed the Wiki. I'm at a loss. Any pointers appreciated. Greg On Jul 26, 2008, at 12:15 PM, Russ Cox wrote: In the Wiki on configuring a standalone cpu server, there is a part that says to run auth/keyfs to provide a password for the machine. Assuming a fresh install, this is done while logged in as glenda. Is this really necessary? Is it different from zeroing the nvram and then entering authid, password, etc.? Yes, and yes. Auth/keyfs is the authentication database. It holds key info for every user in the authentication domain it serves, including whatever user the cpu server itself runs as. Filling out the nvram sets the info that gets used to initialize the cpu server's factotum. Like any other factotum, it needs to have a key that matches the one in authentication database. Auth/keyfs could plausibly preinitialize the entry for the host owner using the nvram key, and that would be fine most of the time, but not always. (It is possible to boot in one auth domain but load an auth/keyfs and be an auth server for a second domain.

So, the kernel I'm trying is based on pccpuf. In anticipation of taking /root from the file server, I also made a kernel based on pccpu. I did the same thing to both: added "il" under "ip" and under "boot" (of course that's just uncommenting in pccpu), put il.c in /sys/src/9/ip/, and added Logil and Logilmsg to ip.h. Build went fine. Copy to 9fat. Menuitems in plan9.ini, and I'm good to go. The reason I'm boring you with that information, and the part I found interesting, is this. Just for the heck of it I selected my "CPU, File Server Root" option, i.e. I booted from 9pccpu instead of 9pccpuf.

Re: [9fans] CPU Server Wiki, auth/keyfs,
After expending all this time and energy, it turns out I was just getting the srv command wrong. And even after typing the command about 1000 times, hoping it would work, it never occurred to me that I should be using the port number. What a dope. Thanks.

[9fans] Venti arenas and index guidelines
Obviously I've had time on my hands to play with computers this week. I have a fossil on an 18G hard drive, which from what I've seen, is probably a much larger fossil than I need. However, I wasn't planning on changing it unless it's really trivially easy to do so. I also have another 18G drive and two 50G drives. I thought the thing to do would be to mirror the 50G drives for venti arenas and that would leave the 18G drive for isects (and bloom?). Any recommendations on how to proceed. Thanks. Greg
[9fans] Subject: Venti, redundancy, and hardware failure.
Sorry if this is a repost, but I haven't seen it show up on groups, so I think I'm OK. I recently asked about mirroring venti arenas and was told that mirroring is generally a good idea. It occurred to me that, although I know how to mirror my arenas, I'm not clear on how to recover from hardware failure. That is, suppose sdD0 and sdD1 are dedicated to arenas, they are mirrored, and venti.conf has something like 'arenas /dev/fs/arenas'. Now suppose sdD0 goes belly up. Do I change '/dev/fs/arenas' to '/dev/sdD1/arenas', in venti.conf and fossil conf? Maybe rerun fmtindex? I recall reading about setting up venti and recovering fossil from venti, but I don't remember seeing anything about this. Also, I was looking at venti-backup. I assume that using it to 'incrementally back up a Venti server to another Venti server' could also include just copying the arenas to another device on the same machine. Is that right? Even if I can use venti-backup tools in this way, is mirroring preferable when it's possible? Why or why not? (Hah! Sounds like a quiz. Bad college flashback. :-)) Greg
[9fans] Quick ms macros question
This is a bit more mundane than recent discussions, but I
noticed that the ms macros contain this
.ie h .ll \\n(LLu
.el \{\
.ll 5.0i
.if n .if \\n(TN .ll 29
.if t .if \\n(TN .ll 3.5i \}
as part of .de TL. What is '.ie h'? I thought the only single character
conditions were e, o, n, or t. /sys/doc/troff confirms this, and a look
at the sources left me wondering. So, again, what does '.ie h' mean?
Thanks.

[9fans] troff, refer, and diversions
I've been writing a paper using -ms macros and refer and refer seems to work as advertised. Recently I decided I wanted to get references in endnotes instead of footnotes, so I added some very simple macros, like FS/FE, around a diversion, thus: .de XS .ev2 .da XA .br .. .de XE .br .di .ev .. Aside from defining some number registers, the footnote macros FJ and FK really don't seem to have much more to them than XS/XE, and the XS/XE pair work as expected when I use them in the text. However, when I replaced the FS/FE pairing under [2 in tmac.srefs, the references are output in the text where I had the tags for refer instead of being put into the diversion. I messed around with variations on the macros much of the day and can't figure out what I'm doing wrong. I can't see why FS and FE will work in the sref macros, but XS/XE won't! Thanks and Happy Holidays. I can't believe it's almost Christmas again! Greg
Re: [9fans] troff, refer, and diversions
Well, I guess it's bad form to respond to your own post, but just for the record, I realized that at least one of those number registers that gets set in the footnote macro is important; namely, the one that says you're in a footnote. In tmac.srefs, the macros that print the references use .IP, which in turn calls .RT, which helpfully ends diversions that the user may have forgotten to close. Of course, this all happens before the rest of the reference macro, so the reference never ends up in the diversion. The sad part is that it took me over 24 hours to realize it.

[9fans] Sources Gone?
I usually try to avoid the "what happened to sources" email, but what happened to sources? All I've been getting from pull attempts for the past several days is srv: dial tcp!sources.cs.bell-labs.com!9fs: connection refused bind: /n/sources/plan9: '/n/sources/plan9' does not exist servermount: bind 545911: bind Could there be something wrong at my end?

Re: [9fans] 9atom and USB Keyboard Problem
Thanks Erik. That helped. Now I only get multi-character output periodically. I don't know what triggers it, but at least I can type. Turns out the mouse has the same problem. Button-3 click in acme sends the text flying by. I don't know how many clicks are being sent. erik quanstrom writes: > > can you try changing the default initial repeat from t = 160 to t = 500 (ms)? > you will need to do a mk install in /sys/src/cmd/usb, and then rebuild your k > ernel. > > let me know if this makes the output a bit more reasonable. > > - erik
