format output of xdotool window geometry

Question

I have the following xdotool output from the shell:

Window 98566146
  Position: 5,279 (screen: 0)
  Geometry: 960x480

I want it to be :

 x=5
 y=279
 width=960
 height=480

with awk, sed, or other tools.

CLARIFICATION: I want to format output of xdotool search --sync --class mpv getwindowgeometry the way I described above using regular expression replace techniques via awk, sed or other tools. There is an example in the following link sed/awk replace a specific pattern under another pattern.

Such as

echo -e "Window 98566146\n  Position: 5,279 (screen: 0)\n  Geometry: 960x480\n" | awk ....

EDIT2:

Actually I could try the following awk line:

  echo -e "Window 98566146\n  Position: 5,279 (screen: 0)\n  Geometry: 960x480\n" |  awk -F'[:]' '{if (NR>1) print $2}'

Answer 1

$ awk -v RS= -F'[[:space:]:,x]+' '{printf "x=%d\ny=%d\nwidth=%d\nheight=%d\n", $4, $5, $9, $10}' file
x=5
y=279
width=960
height=480

Answer 2

You can also do it with this somewhat rudimentary approach, using tr and relying on shell word splitting:

$ alias XDR='echo -e "Window 98566146\n  Position: 5,279 (screen: 0)\n  Geometry: 960x480\n"'
$ XDR | tr -dc '0-9 ,x' | tr ' ,x' ' '

which returns

98566146   5 279  0   960 480

then just feed it to the shell - I'd suggest using ( ) to protect the current environment:

$ (set $(XDR | tr -dc '0-9 ,x' | tr ' ,x' ' ') &&\
   echo -e "x=$2\ny=$3\nwidth=$5\nheight=$6")

or in bash, use process substitution to pull it directly into variables:

$ read wid x y scr width height < <(XDR | tr -dc '0-9 ,x' | tr ' ,x' ' ')
$ echo -e "x=$x\ny=$y\nwidth=$width\nheight=$height"

update - the following works just as well:

$ XDR | tr -c '0-9' ' '

Answer 3

There are lots of ways to do this. Here's a really basic method:

$ awk -F'[:,x]' '/Position:/ { sub(" .*","",$3); printf "x=%i\ny=%s\n", $2,$3};
                 /Geometry:/ { printf "width=%i\nheight=%i\n", $2, $3}' xdotool.txt 
x=5
y=279
width=960
height=480

This uses either a colon, a comma, or an x as the field separator. It also uses sub() to remove the space character and everything after it from the y value ($3) on the Position: line.

xdotool.txt is a text file that contains your example xdotool output.

Answer 4

Another way to do this using awk can be firstly, setting FS for getting the data of interest into a field, $2 in this case:

awk -F'^ +Position: |^ +Geometry: |[()]'  'NR>1{print $2}' file
5,279
960x480

Secondly, we can split the data records 2 and 3 with split() function and print them adding the prefixes you need:

awk -F'^ +Position: |^ +Geometry: |[()]'  '
   NR == 2 {split($2, a, /,/);print "x="a[1]"\ny="a[2]}
   NR == 3 {split($2, a, /x/);print "width="a[1]"\nheight="a[2]}
' file
x=5
y=279
width=960
height=480

Answer 5

Tested with GNU sed and busybox sed:

sed -nEe 's/^[[:space:]]+Position: ([[:digit:]]+),([[:digit:]]+) \(screen: 0\)$/x=\1\ny=\2/p' -e 's/^[[:space:]]+Geometry: ([[:digit:]]+)x([[:digit:]]+)$/width=\1\nheight=\2/p'

Answer 6

We implement hashes in sed using GNU version of the sed editor in extended regex mode -E

fmt=',x=%d\ny=%d\nxwidth=%d\nheight=%d'
sed -En '
  1{x;s/.*/'"$fmt"'/;x;}
  /Position:|Geometry:/G
  s/.*\s([0-9]+)([x,])([0-9]+)\s.*\n\2([^=]+=)%d([^=]+=)%d.*/\4\1\5\3/p
' file
x=5
y=279
width=960
height=480

Another method is using python and nested list comprehension:

python3 -c 'import sys
## separator based on first field
s = { "Position:" : ",",
      "Geometry:" : "x" }

## string format based on first field
f = { "Position:" : "x={}\ny={}",
      "Geometry:" : "width={}\nheight={}" }

with open(sys.argv[1]) as fh:
  print(*[f[f0].format(*(f1.split(s[f0]))) for l in fh for f0,f1 in [l.strip().split()[0:2]] if f0 in f],sep="\n")
' file
