Dietline

Dietline supports two major configuration modes : Emacs-mode and Vi-mode.

Autocompletion

In the every shell and radare2 command autocompletion is supported. There are multiple modes of it - files, flags, and SDB keys/namespaces. To provide the easy way to select possible completion options the scrollable popup widget is available. It can be enabled with scr.prompt.popup, just set it to the true.
