set wallpaper to hex color instead of image file about m-cli

[jdf221]

I don't have the time to set this up with a PR for the wallpaper plugin but here is a bash script that will generate a 1x1 BMP file for a specific hex code:

hexCode="b3a33e"

# Below are the bytes representing a 1x1 BMP. We substitute in the HEX color values from the above hex code into the appropriate byte positions
# Note that BMP uses BGR (Blue Green Red) instead of RGB (Red Green Blue)
bmpBytes="\x42\x4D\x44\x00\x00\x00\x00\x00\x00\x00\x3E\x00\x00\x00\x28\x00\x00\x00\x01\x00\x00\x00\x01\x00\x00\x00\x01\x00\x01\x00\x00\x00\x00\x00\x06\x00\x00\x00\x12\x0B\x00\x00\x12\x0B\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x${hexCode:4:2}\x${hexCode:2:2}\x${hexCode:0:2}\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00"
targetTempFile=$(mktemp)
echo -n -e "$bmpBytes" > "$targetTempFile"


echo "$targetTempFile"

Tested setting my wallpaper to this BMP and it fills the whole screen as long as the wallpaper is set to a setting that attempts to fill the screen.

Great idea @jdf221! I found out that bmp file can be even smaller.
I have improved that script a bit and now it works perfectly. Thanks.

#!/bin/sh

# hex2bmp 

while read -r hex; do

  out=$(mktemp)
  printf "424d1e000000000000001a0000000c0000000100010001001800%s00" \
         "${hex:4:2}${hex:2:2}${hex:0:2}" | xxd -p -r > "$out"
  echo "$out"

done

m wallpaper $(echo 2B3339 | hex2bmp)

That's a great solution, if I get time I'll try putting a PR together for it

An interesting request. I'm terrible with Applescript, and I suspect that's the way to do it. If anyone else knows of a way, I'm happy to help, otherwise this might take a while...
