question about opening files with lf file manager

I want to open .webm, .mp3, .flac kind of files with lf but I didn't manage to it. here my lfrc config.

# Basic vars
#set icons
set cleaner '~/.config/lf/cleaner'
set previewer '~/.config/lf/scope'
set drawbox
set ignorecase true

cmd open ${{
  case $(file --mime-type $f -b) in
    image/vnd.djvu|application/pdf|application/octet-stream) setsid -f mupdf $fx >/dev/null 2>&1 ;;
    text/*) $EDITOR $fx;;
    image/x-xcf|image/svg+xml) setsid -f gimp $f >/dev/null 2>&1 ;;
    image/*) nsxiv $f | grep -i "\.\(png\|jpg\|jpeg\|gif\|webp\|tif\)\(_large\)*$" | sxiv -aio 2>/dev/null | lf-select ;;
    audio/*) mpv --audio-display=no $f ;;
    video/*) setsid -f mpv $f -quiet >/dev/null 2>&1 ;;
    application/pdf|application/vnd*|application/epub*) setsid -f mupdf $fx >/dev/null 2>&1 ;;
    *) for f in $fx; do setsid -f $OPENER $f >/dev/null 2>&1; done;;
  esac
}}

cmd mkdir ${{
	printf "Directory Name: "
	read ans
	mkdir $ans
}}

cmd mkfile ${{
	printf "File Name: "
	read ans
	$EDITOR $ans
}}

cmd delete ${{
	clear; tput cup $(($(tput lines)/3)); tput bold
	set -f
	printf "%s\n\t" "$fx"
	printf "delete?[y/N]"
	read ans
	[ $ans = "y" ] && rm -rf -- $fx
}}

#bindings
map . set hidden!
map p paste
map x cut
map y copy
map <enter> open
map A rename
map r push A<a-b><a-b><a-f>
map D delete

map m

Re: question about opening files with lf file manager

    OPENER

       If this variable is set in the environment, use the same value, otherwise set the value to 'start' in Windows, 'open' in MacOS, 'xdg-open' in others.

echo $OPENER
xdg-open

set up xdg-open to do what you want.

Okay everything works well expect audio files .mp3 .flac still not opening when I press open button nothing happens. my latest lfrc config:

cmd open ${{    
    test -L $f && f=$(readlink -f $f)    
    case "$(file --mime-type "$f" -b)" in    
        text/*) nvim $fx;;    
        audio/*) mpv --audio-display=no $f ;;    
        *) for f in $fx; do xdg-open $f > /dev/null 2> /dev/null & done;;    
    esac    
}}

Re: question about opening files with lf file manager

i just tried your config and it works fine so you've got somthing else going wrong somewhere

EDIT: just to clarify i used your 'open' config not your whole lfrc

I think it is about file names. I have file named  "Vengaboys - Boom, Boom, Boom, Boom!!.flac" I tried opening that, it gave this error:

--: line 2: test: syntax error: `-' unexpected

I changed  name to "boom.flac" for testing, now I can open the file. Any idea why this happens?

Re: question about opening files with lf file manager

i figured it out, i have this at the top of my lfrc which is part of the lfrc example (/usr/share/doc/lf/lfrc.example):

# interpreter for shell commands
set shell sh

# 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

this is the bit your after:

set ifs "\n"

will fix your problem like magic !

Re: question about opening files with lf file manager

Additionally, set ifs to "\n" in case you want $fx to work correctly when multiple files are selected.

EDIT: Too slow.
