Applying transset to all xterm windows automatically

Hi,

I would like to know if it's possible to auto apply transset to all terminal windows.

A simple (but not too elegant) solution using xdotool:

while true; do for wid in $(xdotool search --class XTerm); do transset-df --id $wid 0.85 &>/dev/null; done; sleep 0.1; done

If you use something other than xterm, find out the --class argument to xdotool by using:

xprop WM_CLASS

and click on your terminal. Use the second string reported.

Thanks, that works.
By not too elegant, did you mean 'take up 30% of your CPU'-non elegant?
The reason I came to Arch is mainly because I like having a 0% load when I am not really doing much but browing and IM.

you could use wmctrl -l | awk to find all your terminal's winid's and apply the transset-df command to each. you could also write a wrapper script to act as your terminal. this wrapper could launch a term and (re)apply the transparencies. i alway try to avoid while true loops idling in the background...

seems easier to just use urxvt + Xdefaults though...

How do I get urcvt, I'm quite new, and I can't find it with pacman.

Exactly It was just the first thing that came to mind... it's probably simpler to do what brisbin33 suggests.

hehe, you could [spell it right, and] search the wiki .

If you still want to use xterm and transset, i wrote a (rather useless) bash script tairu, that uses a small c-application (tairu_notify) which does nothing but waiting until a new window is opened or closed, the source-code can be found here (can be compiled with gcc -lX11 tairu_notify.c -o outputname). So

while :; do 
  tairu_notify
  for wid in $(xdotool search --class XTerm); do 
    transset-df --id $wid 0.85 &>/dev/null 
  done 
done

only checks for new xterms, if a new window is opened or closed.
If you change line 16 in tairu_notify.c to

if (e.type == CreateNotify) {

it will only check, if a new window is created.

@portix: That's what I was looking into, too, but I didn't get very far with my limited c. Thanks for posting!

I have also a modified version here.
It takes the window class as an argument and prints out the window id.

yeas devilspie (extra/devilspie) look like the correct solution for me I have this

(if

(matches (window_class) "URxvt")
(begin
  (spawn_async (str "transset-df -i " (window_xid) " .95" ) )
)
)

And never noticed any cpu usage. (and have another 6 or so files like this)

Thank you, I tried pacman -S urxvt, but the package was called rxvt-unicode. I am going to try this, the config I found in you sig looks cool.
