himawari8 wallpaper for linux

I recently read about the script on PowerShell, which put pictures from the satellite wallpaper on the desktop. Googling, did not find implementation under linux - which is lower.

Possible problems

On a trifle: the server does not always load images directly completely new, so there is a chance to stumble upon emptiness. Therefore, in the script I get the pictures of the last day: nowday=$(date +%d -d -1day)

UPD: fixed, the problem was in the unconfigured time zone.
')
The server loads a new pak of photos every ten minutes and requires rounding up to tens. therefore

nowtime=$(date +%H%M | sed -r 's/.$//')
nowtime=$nowtime"000"

Special problems here in one place: in the installation of wallpaper on your desktop.

For xfce4

General syntax

xfconf-query -c xfce4-desktop -p %desktoppath% -s %image%

Getting parameters

You open /home/user/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml

Suppose there is something like:

 <channel name="xfce4-desktop" version="1.0"> <property name="backdrop" type="empty"> <property name="screen0" type="empty"> <property name="monitorVGA-0" type="empty"> <property name="workspace0" type="empty"> <property name="color-style" type="int" value="2"/> <property name="image-style" type="int" value="5"/> <property name="last-image" type="string" value="/home/user/pictures/my_standart_wallpaper.png"/> </property> </property> </property> </property> </channel>

So, instead of %desktoppath% you must specify /backdrop/screen0/monitorVGA-0/workspace0/last-image

Well, %image% is the full path to the new image file.

I didn’t get in touch with the authors, but I think they weren’t just loading it into open access.
