cm3us: m3u file → cmus playlist

Convert playlists from android m3u with hardcoded paths to cmus playlists with different hardcoded paths.

So no editing from cmus which I would seldom do anyway

1. On cmus start call cm3us
2. For every playlist in ~/Documents/Playlists/, replace '/storage/emulated/0/Music/' (android library dir) with '/home/molnar/Music/MusicLibrary/' (linux library dir)
3. Save output to ~/.config/cmus/playlists

#!/bin/bash
# convert android m3u playlist to cmus playlist
 
# cmus playlists location
CMUSDIR="/home/molnar/.config/cmus/playlists/"
# m3u playlists location
M3UDIR="/home/molnar/Documents/Playlists/"
# cmus music library
CMUSPATH="/home/molnar/Music/MusicLibrary"
# m3u music library on android
M3UPATH="/storage/emulated/0/Music"
 
# m3u to cmus playlist
for pl in $M3UDIR*;
do
	# sed 's/\/storage\/emulated\/0\/Music/\/home\/molnar\/Music\/MusicLibrary/g' "$pl" > "$cmuspl";
 
	tmp=$(mktemp)
	plname="${pl##*/}"
	cmuspl="${CMUSDIR}${plname%.*}"
	while IFS= read -r s; do
		s=${s//"$M3UPATH"/"$CMUSPATH"}
		printf '%s\n' "$s" >> "$tmp"
	done < "$pl"
	mv "$tmp" "$cmuspl"
done
