Created a wrapper script to customize theme variables (colors, fonts, etc) according with your X resources file (~/.Xresources). As dunst is not a X exclusive notification daemon, this script could be a workarround to solve this. Related with: #357master

## |
||||
## Usage |
||||
## |
||||
## ./<script_name> [<OPTIONS>] |
||||
## |
||||
## If it does not run, give execute permissions to the script with |
||||
## chmod +x <script_name>. Then run ./<script_name>. |
||||
## |
||||
## Options |
||||
## |
||||
## -h|--help Optional. Show help message. |
||||
## |
||||
## Description |
||||
## |
||||
## This script creates a dunst themed user config in $HOME/.config/dunst/ |
||||
## folder, changing dunst basic theming options (like fonts, colors, etc.) |
||||
## according to your current X resources color palette. |
||||
## |
||||
## To make this possible, it reads your current user config |
||||
## ($HOME/.conf/dunst/dunstrc, which is copied from the default config if |
||||
## it does not exist) and changes the attributes values with new ones (see |
||||
## Theming section for more info). Then it dumps the new configuration to |
||||
## $user_xr_color_conf file. |
||||
## |
||||
## Theming |
||||
## |
||||
## To change colors and fonts: |
||||
## |
||||
## * Firstly you have to ensure that those dunst attributes are defined in |
||||
## the corresponding sections. For example, to change the frame_color |
||||
## value from the global section, in $HOME/.config/dunst/dunstrc should |
||||
## be: |
||||
## |
||||
## ... |
||||
## [global] |
||||
## ... |
||||
## frame_color = <value> |
||||
## ... |
||||
## |
||||
## * Then, you can change attribute values as you wish with the |
||||
## following format in theme_attr_dict: |
||||
## |
||||
## ["<sec>-<attr>"]="<val>|$(xrdb_get '<X_res>' '<dev_val>')" |
||||
## |
||||
## Each <variable> means the following: |
||||
## |
||||
## * sec - current section name e.g.: global. |
||||
## * attr - current attribute name e.g.: frame-color. |
||||
## * val - a simple value e.g.: "#fffeee", Monospace, 11... |
||||
## * X_res - X resource name e.g.: color8. |
||||
## * dev_val - default value to set if X_res is not found e.g.: #65737e. |
||||
## |
||||
## Theming example (you can check theme_attr_dict for other values): |
||||
## |
||||
## ["global-frame_color"]="\"$(xrdb_get 'color8' '#65737e') |
||||
## |
||||
## The function xrdb_get, searches the first parameter in the X resources |
||||
## database with appres (command installed from xorg-appres in archlinux |
||||
## and x11-utils in ubuntu). If the first parameter does not exist, the |
||||
## function returns the second parameter. For hex colors, is important to |
||||
## scape " characters for proper functioning of dunst config reader (for |
||||
## example "#ffeegg"). |
||||
## |
||||
## You can define X_res variables in $HOME/.Xresources file. For in depth |
||||
## syntax go to https://wiki.archlinux.org/index.php/X_resources. |
