Re: [9fans] htmlroff -ms footnotes
It isn't the Abstract, it's the .SH, which calls .RT, which somehow changes the FS macro. If you replace .SH with .RT in test.ms nothing changes; if you delete it altogether the missing footnotes appear. If you put .pm above and below .SH (or .RT) and run: ; htmlroff -ms -mhtml test.ms >/dev/null |[2] grep FS you can see that the FS macro is being messed with. I'll dig further... umbraticus -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T530822947a31ba06-M34d92b1177885d8baf1d0ab6 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

Re: [9fans] use of plumber for new rule
Here's my rule for manpages: data matches (.+)\(([0-9])\) arg isfile /sys/man/$2/$1 plumb start rc -c 'man -t '$2' '$1' | plumb -id image' which replumbs the cmd output to the image port; then: dst is image plumb to image plumb client rc -c 'window -r 380 0 1600 900 ''echo -n page >/dev/label; bind /dev/mordor /dev/label; page -i -p180 -m64''' either sends it to any existing page instance or else starts a new one to send it to. Worth noting I am using 9front's version of page, which listens on the image port; can't recall if the original listens on the postscript port in a similar way: probably. If you just want to pop open a new window with your dvi each time you can use a plumb start rule that does whatever you want; something like: data matches '([a-zA-Z¡-�0-9_\-.,/]+)\.(dvi|DVI)' arg isfile $0 plumb start window kertex/dvips $0 '|' page There are other workflows too, if what you want is a tight loop for editing a document and seeing the new version. Some people use a watch(1) program that runs a command whenever a given file changes. I prefer to tie the file write and doc gen to a single command using (9front) sam's ^ cmd, which sends its output to sam's command window: ^echo w; window troff $% '|' page The last shell command is remembered, so subsequent write'n'reviews are a simple ^ thereafter. umbraticus -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tce7385fe52c532d6-Me347adb350456cff65756620 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

Re: [9fans] Autoexpand in sam
Another related convenience is to have a rule somewhere near the bottom of your plumbing file that pops up a window and prints the dictionary listing for the word you plumbed. If I could remember who it was I would thank the person who recommended this to me because I use it all the time. If you are confident with the first part of a word look(1) could be handy. You could also write a filter that transposes letters until it finds a match in /lib/words.

kvik also has some window placement hacks:
https://git.sr.ht/~kvik/ham
There was a video demo somewhere.
To understand sam's automatic window placement around the
cmd window, resize cmd to a square in the centre and
experiment with creating new windows by clicking in various
regions around the square. There is afaik no way to save &
reproduce window geometry; as mentioned above, I just open
everything fullscreen.

I wrote this (improvements welcomed) but it relies on the ^

your version of sam. I believe it was brought to your attention
for these functions, which load a previous editing session:
# ^d [file] # save unwritten changes and dump sam state to file

dump = /tmp/sam.dump

Re: [9fans] Help with a sam cleanup script
also worth mentioning the ^ command if you're using 9front's sam. put your sam commands in script like this: #!/bin/rc cat << STOP x/ +/c/ x/\*/d STOP then you can run ^script and it will apply the commands. Note that if you leave off the commas before the commands, as I have above, you will have to set dot before running ^ but this allows more flexibility, eg. you can apply the edits to a section of a document instead of always the whole thing. One step at a time, though.

There is a patch for this floating around somewhere: perhaps

Re: [9fans] Command to set samterm label
> That's run by sam, not samterm. Ah, I see; /dev/label is not available to the remote end of sam -r. Do people use sam -r a lot, instead of [r]cpu -c sam? Is it appreciably faster? surely having /mnt/term & local /dev in the namespace is nice? Anyway, I see your point. Still not convinced setting the window label belongs inside the editor (or the editor's wm) since it is a feature of rio... If you use winwatch some have patched it to make setting label more convenient, or you could have a script that does: ; label sam $files; bind /dev/null /dev/label; sam $files I discovered this trick when I wanted my persistent page always to be labeled as such rather than change based on whatever it is displaying. > It's for using multimple instances of sam. Sure, was just pointing out if !label was sufficient you could simplify your patch to just tweaking the initdraw call. (Maybe it would be nice to print all files listed on the command line) On the odd occasion I have multiple sams, I prefer to set the label myself to project1, project2 but having the filename(s) there initially might be nice. You could even get clever and have the label change to reflect the most recently active buffer. umbraticus -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tf1e211daf823c0e0-M1e8dc73ec3b6f44f7e047e5b Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

Re: [9fans] focus window on plumb
Even simpler, run the following program in riostart thus:
window 'raiseplumb web & mothra'
window 'raiseplumb edit & sam'
could probably even be an rc script
#include
#include
#include
void
main(int argc, char **argv)
{
Plumbmsg *m;
int port, wctl;
if(argc != 2)
sysfatal("usage: %s port", argv[0]);
if((port = plumbopen(argv[1], OREAD)) < 0)
sysfatal("couldn't open plumb port %s", argv[1]);
if((wctl = open("/dev/wctl", OWRITE)) < 0)
sysfatal("couldn't open /dev/wctl");
for(;;){
if((m = plumbrecv(port)) == nil)
sysfatal("error on plumb port %s", argv[1]);
plumbfree(m);
fprint(wctl, "unhide");
fprint(wctl, "current");
}
}

[9fans] focus window on plumb
Hi 9fans,
I wrote the attached to listen on a plumb port and make
a given window current when it gets a message. I'm not
sure how much I will like it: it's nice not to have to
hunt for a buried client program after plumbing something;
on the other hand, sometimes I like to plumb a few urls,
images, or pdfs and view later. Still, I thought I'd
figure out a way to do it.
The first argument is the port to listen on and the second
is a string to match against the label of the window to
raise. In my riostart I start my main rc window like this:
window 'raiseplumb web mothra! & raiseplumb edit sam & raiseplumb image page &
cat todo; label rc; rc'
(After setting page's label I bind /dev/null over it so it
isn't overwritten) The program could be improved but it
seems to work well enough for a quick implementation.
Other solutions I thought of were to prime the windows I
want to raise by posting their wctl in /srv (since /dev/wsys
isn't in the plumber's namespace) then writing plumb rules
to first raise the window by mounting the wctl, then plumb
to the port; or else patch the client programs to raise
themselves when they get a plumb.
Has anyone else wanted/implemented something like this?
