dotfiles/.config/lf/lfrc

## Basic Settings
### interpreter for shell commands (needs to be POSIX compatible)
set shell sh
### view hidden files
set hidden
set info size:time
set previewer lf-preview.sh
#set previewer /usr/bin/pistol
### Enable icons. Requires nerd fonts and LF_ICONS variable.
set icons
set ignorecase true

### set '-eu' options for shell commands
### These options are used to have safer shell commands. Option '-e' is used to
### exit on error and option '-u' is used to give error for unset variables.
### Option '-f' disables pathname expansion which can be useful when $f, $fs, and
### $fx variables contain names with '*' or '?' characters. However, this option
### is used selectively within individual commands as it can be limiting at
### times.
set shellopts '-eu'

### set internal field separator (IFS) to "\n" for shell commands
### This is useful to automatically split file names in $fs and $fx properly
### since default file separator used in these variables (i.e. 'filesep' option)
### is newline. You need to consider the values of these options and create your
### commands accordingly.
set ifs "\n"

### leave some space at the top and the bottom of the screen
set scrolloff 10
