This is an adoption of the arcticons icons for Linux desktop managers like GNOME and KDE.
Important: to generate the icons you need to clone the parent repo https://github.com/Donnnno/Arcticons with the --recurse-submodules argument (or run git submodule update --init afterwards) and switch to the freedesktop-theme folder.
The ./generate-manual.sh script can be used to generate the icons according to the mappings file. it accepts two arguments:
./generate.sh black/white <stroke thickness>
The first argument is used to control whether the white or the black icons are generated. (default is white)
The second argument is a number which controls the stroke thickness of the generated icons. (default is 1)
After the icons are generated, there is a folder arcticons and a arcticons.tar.gz file.
You can install the icon theme by copying the arcticons-light and/or arcticons-dark folder into ~/.local/share/icons for an user-wide installation or into /usr/share/icons for a system-wide installation.
In GNOME Shell, you can either use the Terminal and type the command gsettings set org.gnome.desktop.interface icon-theme <arcticons-light/arcticons-dark> or use the GNOME Tweaks GUI to change the icon theme to Arcticons Light or Dark. (To change the icons for Qt/KDE applications in GNOME as well, you need to open qt5ct and/or qt6ct and select the icon theme there)
In KDE, you can select the icon theme in the System Settings > Icons.
The mappings.txt contains the mappings of the arcticons in the format <Arcticon icon name>,<Freedesktop icon path>:<Freedesktop icon path>
When one Arcticons icon is used for multiple icons in the freedesktop theme, the paths are separated by a :.
To contribute, you need to look the path of the original icons. Application icons are in /usr/share/icons/hicolor/<icon size>/apps, while system icons are covered by the other icon themes. (In GNOME, the default is Adwaita; For KDE Plasma, it's Breeze) The icons are either in the <icon size>/<icon category>, or in <icon category>/<icon size> subfolders.
For example, the icon for the Steam application is in /usr/share/icons/hicolor/<icon size>/apps/steam.png, while the system icon for Wi-Fi is in /usr/share/icons/Adwaita/symbolic/devices/network-wireless-symbolic.svg. The -symbolic part of the file name specifies, that the icon is theme-aware, but because only the fill color and not the stroke color is theme-aware, Arcticons can't take advantage of this.
The Freedesktop icon path in the mapping file refers to the path <icon category>/<icon size>, without the file extension. So /usr/share/icons/hicolor/<icon size>/apps/steam.png is written as apps/steam in the mappings file.
Some application files may also be found in the /usr/share/pixmaps folder, then the mapping path is apps/<icon name>.
To contribute icons, which don't fit into the Android icon pack, you can place them into the icons_linux folder (there has to be one with stroke color #000 in the black folder and one with stroke color #fff in the white folder). The style of the icons and the structure of the SVGs have to follow the style used in the parent repo.
Then follow the section Mapping the icons the put the mapping into the mappings.txt.
