Re: [9fans] How to take a portion of a screenshot
Nice. Looking at jpg(1) sources, it's not obvious where the allocation
limit comes in. Too bad there isn't an encoder for vp8.
for mouse position, you may need to write a shim to snoop on the mouse;
something like this:

Re: [9fans] How to take a portion of a screenshot
Thanks Skip, Cinap,
This command seems to be working quite nicely (except for the memory allocation
problem in gif(1) for larger recordings):
for (i in `{seq -w 1 25}) { sleep 0.01; cat /dev/screen > /tmp/screen-$i.img };
togif -l -1 -d 300 /tmp/screen-*.img > /tmp/recording.gif; rm
/tmp/screen-*.img; echo Done
It would be easy enough to introduce a crop to restrict the recording to a
particular window or area of the screen.
Is there a way to capture the current mouse position without blocking to wait
on an event from /dev/mouse? I was thinking that it would be interesting to
crop around the current mouse position.

Re: [9fans] How to take a portion of a screenshot
rc variables are lists, and $#var evalulates to the
length of the list... you can use that to make counters
by concatenating elements to a list:
term% a=() while(! ~ $#a 13){echo $#a $a; a=(1 $a);}
0
1 1
2 1 1
3 1 1 1
4 1 1 1 1

most of the time seq(1), hoc(1) and similar tools can help do the job:
fn square {
echo $1 '*' $1 | hoc
}
for (i in `{seq 1 10}) {
j = `{square $i}
echo $i^² '=' $j
}

awk printf perhaps?
for (i in (0 10 100)) {
echo $i
} | awk '{printf "image_%0.3d\n", $0}'
Re: [9fans] How to take a portion of a screenshot
I tried to write an rc script that would make a screen video as an animated gif. I have something that almost works, but ran into a few problems/limitations. * I can’t seem to find a way to have an incrementing loop counter in rc shell (best I could do is check the size of a growing list variable) * The gif command barfs when the GIF is any larger than a few megabytes due to an allocation error * I couldn’t think of a good way to name the image files so that they can be sorted into the correct sequence as input to togif I’ll try banging my head on the solution again tomorrow. I’m hoping that either it can be a one-liner of rc shell scripting or put into a full utility script (e.g. recscreen) that anyone could use.

kudos for the use of m4. sadly my o2s went the way of ebay years ago, nice machines though. -Steve > On 23 Nov 2016, at 21:30, Jules Merit > wrote: > > I ported doom, after someone Runed plan9.

i have a slightly related question: how do i find out an other window's window id if there is no shell temporarily available? e.g. doom is running inside.

Thanks Richard, That is the kind of thing I was looking for. And yes, it's one of the reasons I'm liking plan 9. Each piece does one thing we'll.

can't you take something like /dev/wsys/123/window ?
