Dependency graph of installed packages on your wallpaper. IMPROVED!

pacwall.sh is a shell script that changes your wallpaper to the dependency graph of installed by pacman 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).

Changes in this fork

• (optionally) parse pywal for color data
  • colors for nodes, etc can be exchanged for other colors exported by pywal
  • if pywal is not installed (~/.cache/wal does not exist), use default colors
• feh removed, instead using hsetroot
  • hsetroot is more minimalistic (0.04MiB)
  • removes the dependency on imagemagic (9.72MiB)
  • removes the dependency on feh (0.17MiB)
  • removes the need to manually set SCREEN_SIZE

Requirements

• graphviz
• pacman-contrib
• hsetroot
• python-pywal (optional)

sudo pacman -S graphviz pacman-contrib hsetroot pywal

Customization

Any customizations should 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.

Troubleshooting

If the graph is too large, add a -Gsize flag to the twopi invocation, like here:

twopi \
	-Gsize="7.5,7.5" \
	-Tpng pacwall.gv \
	-Gbgcolor=$BACKGROUND \
	-Ecolor=$EDGE\
	-Ncolor=$NODE \
	-Nshape=point \
	-Nheight=0.1 \
	-Nwidth=0.1 \
	-Earrowhead=normal \
	> pacwall.png

The flag forces the graph to be not wider nor higher than 7.5 inches.

An alternative method is to add a -Granksep flag. For example, -Granksep=0.3 means that the distance between the concentric circles of the graph will be 0.3 inch.
