IPC

There are two main ways of IPC control in durden. The first is through the three named pipes created in durden/ipc/control,output,status at statup. The use of status is described in statusbar and will not be covered here.

control can be used to run menu commands. This is slightly dangerous as quite a number of menu paths were written with an interactive user in mind. Therefore it is also possible to define a custom whitelist (see security so that only benign menu path can be activated externally.

output is used to convey custom messages, like when a user-defined statusbar button is clicked. There is also a hidden menu path (=bind only) that allows you to pass a custom message to the output channel. This path can be found at global/system/output_msg.

There is also a second, more experimental, IPC mechanism that disguises itself as a normal connected client and it is more directed towards experienced developers as you will have to hook into both durden and develop using one of the arcan-shmif API bindings, e.g. TUI (see the arcan wiki for more information) . For a simple example on how this is used to implement a clipboard manager, see clipboard.

This channel can be used for more powerful things as well, like full or partial display sharing or streaming, input injection.
