Hopman is a graphics tool which displays removable partitions currently plugged into the computer. It displays also the partition's label if any, and the mountpoint, if mounted. On click, the user can mount, unmount or open the partition's main directory in a file-manager or a terminal-emulator. Hopman does not perform mount, umount or open by itself. Instead a list of command lines must be provided in the configuration file to specify how to perform these actions and Hopman invoques these command lines. The command lines specified in the default configuration file match the Xfce4 desktop: for mount: pmount, for unmount: pumount, terminal emulator: xfce4-terminal, file-manager: thunar. Hopman uses the GTK+-2 graphics library. Are considered as removable the partitions of disks tagged as "hotplug" by the kernel. The author doesn't know how the kernel decides wether a device is hotpluggable or not but this works with USB memory sticks of small or medium capacity. A future version of Hopman will give a better control on how this decision is made. The key feature of Hopman is the mere absence of dependencies. The only ones are a Linux kernel version higher or equal to 2.6, a C library, the graphics library (ie GTK-+2). In particular, it doesn't depend on Gvfs, Dbus, and, of course, Systemd. While Hopman does not depend on the presence of a hotplugger, it relies on a dynamic creation/deletion of device special files in /dev, and, therefore, it would not be comfortable to use with a static /dev. The dynamic creation and removal of device files do not require a hotplugger and are better done by the kernel itself if built with the DEVTMPFS feature, but a hotplugger is necessary to create the symbolic links in /dev/disk/by-label, on which Hopman relies to know the labels of the partitions; but Hopman is still functionnal without the partitions' labels. Hopman is a purely reactive process; it sleeps all the time except when the kernel awakes it to report a change in /dev, /dev/disk/by-label, or the file /proc/self/mountinfo or when the user requests some action. With the default configuration, the window of Hopman remains invisible when there are no hotplug partitions in the system; it pops up when one is inserted or out when the last is removed.
