# Luke's lf settings


# Note on Image Previews
# For those wanting image previews, like this system, there are four steps to
# set it up. These are done automatically for LARBS users, but I will state
# them here for others doing it manually.
#
# 1. ueberzug must be installed.
# 2. The scope file (~/.config/lf/scope for me), must have a command similar to
#    mine to generate ueberzug images.
# 3. A `set cleaner` line as below is a cleaner script.
# 4. lf should be started through a wrapper script (~/.local/bin/lfub for me)
#    that creates the environment for ueberzug. This command can be be aliased
#    in your shellrc (`alias lf="lfub") or if set to a binding, should be
#    called directly instead of normal lf.
