Overview

The Ucomp class provided to encapsulate typical filename completion procedure. You will not typically use this directly, but will instead use the Readline::USERNAME_COMPLETION_PROC.

Note that this feature currently only works on Unix systems since it ultimately uses the Etc module to iterate over a list of users.
