* https://github.com/bimlas/xfce4-night-mode (*please star if you like the plugin*)



== Command line usage



....

$ xfce4-night-mode.sh [day|night|toggle]

....



*Parameters*



`day`:: Use light variant

`night`:: Use dark variant

`toggle`:: Switch between light and dark variants



Without parameters, it will use dark variant from sunset to sunrise according

to the settings (see later).



== Generic Monitor (Genmon) plugin usage



* First you have to install `xfce4-genmon-plugin` package if it is not on your system

* Add the monitor to the panel

** Right click on the panel

** Select _Panel -> Add new items_

** Add _Generic Monitor_ plugin

* Set up the generic monitor to use with night mode

** Right click on the newly added generic monitor -> _Properties_

** Command: `/path/to/xfce4-night-mode.sh`

** Uncheck the checkbox of _Label_

** Set _Period_ to `300` seconds (5 minutes)



== Settings



For settings, open the XFCE Settings Editor -> `night-mode` channel.



To find out what values to enter, set the color schemes you want and copy them

from the appropriate location:



* GTK theme

** `xsettings/Net/ThemeName`

* Icon theme

** `xsettings/Net/IconThemeName`

* Cursor theme

** `xsettings/Gtk/CursorThemeName`

* Window manager theme

** `xfwm4/general/theme`



The specified `UserScript` will be executed when switching the mode, you can use

this for example to change the theme of the terminal, set desktop wallpaper,

etc. You can use the variable `XFCE_NIGHT_MODE` in your script if you want to

use the same script in both cases, for example:



....

#!/bin/bash

notify-send --icon "dialog-info" "Mode: $XFCE_NIGHT_MODE"

....



=== Example `UserScript`



==== Change wallpaper



First you have to find the property of the wallpaper (this could be different on

multi-monitor setup) by executing the command below then changing the wallpaper

in _Desktop_ setting.



```

xfconf-query --channel xfce4-desktop --monitor

```



You have to execute the command below to set up the wallpaper for this desktop.



```

xfconf-query --channel xfce4-desktop --property  --set 

```



==== Change panel dark mode



You have to execute the command below to change the panel mode opposite to the

windows mode (light windows, dark panel).



```

xfconf-query --channel xfce4-panel --property /panels/dark-mode --set "$([ "$XFCE_NIGHT_MODE" = "day" ] && echo true || echo false)"

```



=== Switch at a time specified by antoher program



For example, to use http://jonls.dk/redshift/[Redshift] or another program to

determine when it is night, use `xfce4-night-mode-redshift.sh` (or a modified

version of it) instad of `xfce4-night-mode.sh` in "Generic Monitor plugin

usage".



== Changes



=== https://github.com/bimlas/xfce4-night-mode/-/compare/v1.0.0\...v2.0.0[2.0.0]



* Add options to change GTK, mouse, icon, and window manager theme

** *Breaking change*: You must set these before use
