pacwall.sh is a shell script that changes your wallpaper to the dependency graph of installed packages. Each package is a node and each edge indicates a dependency between two packages. The explicitly installed packages have a distinct color (orange by default). The dependencies of type X provides Y are represented as an edge with an inverted arrow that points towards Y (applies only to Arch).
sudo pacman -Syu --needed graphviz pacman-contribsudo apt install graphviz debtree- If you are on GNOME (Xorg), you also need
imagemagickandxorg-xdpyinfoto set the wallpaper. - If you are on GNOME (Wayland), you need
imagemagickand to specify the screen size manually like this:./pacwall.sh -S 1920x1200. - If you aren't on GNOME,
pacwalltries to set the wallpaper usingfehandhsetroot.
Customizations can be made on the commandline, see the options with the -h flag.
USAGE: pacwall.sh
[ -i ]
[ -b BACKGROUND ]
[ -d NODE_COLOR ]
[ -e EXPLICIT_NODE_COLOR ]
[ -s EDGE_COLOR ]
[ -g GSIZE ]
[ -o OUTPUT ]
[ -S SCREEN_SIZE ]
Use -i to suppress wallpaper setting.
All colors may be specified either as
- a color name (black, darkorange, ...)
- a value of format #RRGGBB
- a value of format #RRGGBBAAAdditional customizations can be performed by modifying the script itself. The code in the script is well-structured (should be). To discover the customization possibilities, read the man page of graphviz and twopi, particularly the section on GRAPH, NODE AND EDGE ATTRIBUTES.
If the graph is too large, use -r flag. For example, -r 0.3 means that the distance between the concentric circles of the graph will be 0.3 inch.
An alternative method is to use -g flag. The format should be the same as the twopi -Gsize option. 7.5,7.5 for example forces the graph to be not wider nor higher than 7.5 inches.
