osx安装mpd和ncmpcpp

简介

mdp 是一款开源的音乐播放软件, 全名为 media player daemon , 从字面意思理解, 就是一个后台播放进程. 不同于传统的音乐播放软件集成了播放解码和界面, mpd 只是一个后台播放进程, 需要单独的客户端程序与 mpd 进行交互. mpd 的客户端也各种各样, 有浏览器插件/windows客户端/gnome客户端/终端客户端等等, 而今天主要介绍的就是终端客户端程序 ncmpcpp.

mdp 及ncmpcpp 安装

osx 平台下可以使用 brew 命令进行快速安装, 以下命令可以搜索当前本地仓库是否有以上两个应用程序.


➜ brew search mpd
==> Formulae
bandcamp-dl libmpdclient mpdas mpdscribble rtmpdump mpw mad
libmpd mpd mpdecimal ✔ mpdviz mpc mpv
==> Casks
cisdem-pdf-converter-ocr cisdem-pdfmanagerultimate kmbmpdc
➜ brew search ncmpcpp
==> Formulae
ncmpcpp ncmpc

如果仓库中不存在以上程序, 可以使用 brew update 命令更新仓库索引.

使用 brew install 命令安装, 稍待片刻后安装完成后就可以使用 mpd 及 ncmpcpp :

➜ brew install mpd ncmpcpp

配置 mpd

在启动 mpd 之前, 我们需要 mpd 对进行一些配置.

创建 mdp 媒体文件夹

$ mkdir -p ~/.mpd/playlists
$ touch ~/.mpd/{mpd.conf,mpd.db,mpd.log,mpd.pid,mpdstate}
$ ls ~/.mpd/
mpd.conf mpd.db mpd.log mpd.pid mpdstate playlists

创建配置文件 ~/.mpd/mpd.conf, 用于配置 mpd 进程.

$ cat ~/.mpd/mpd.conf
music_directory "~/Music"
playlist_directory "~/.mpd/playlists"
db_file "~/.mpd/mpd.db"
log_file "~/.mpd/mpd.log"

集成 tmux

如果使用 tmux 需要在状态栏显示当前播放歌曲, 可以创建 ~/.tmux/tmux-scripts/np_mpd.sh 脚本文件, 并在 tmux.conf 中配置状态栏. np_mpd.sh 文件如下:

#!/usr/bin/env bash
# Print a simple line of NP in mpd.
# Rolling anything what you want.
# arg1: text to roll.
# arg2: max length to display.
# arg3: roll speed in characters per second.
roll_stuff() {
 local stuff="$1" # Text to print
 if [ -z "$stuff" ]; then
 return;
 fi
 local max_len="10" # Default max length.
 if [ -n "$2" ]; then
 max_len="$2"
 fi
 local speed="1" # Default roll speed in chars per second.
 if [ -n "$3" ]; then
 speed="$3"
 fi
 # Anything starting with 0 is an Octal number in Shell,C or Perl,
 # so we must explicityly state the base of a number using base#number
 local offset=$((10#$(date +%s) * ${speed} % ${#stuff}))
 # Truncate stuff.
 stuff=${stuff:offset}
 local char # Character.
 local bytes # The bytes of one character.
 local index
 for ((index=0; index < max_len; index++)); do
 char=${stuff:index:1}
 bytes=$(echo -n $char | wc -c)
 # The character will takes twice space
 # of an alphabet if (bytes > 1).
 if ((bytes > 1)); then
 max_len=$((max_len - 1))
 fi
 done
 stuff=${stuff:0:max_len}
 #echo "index=${index} max=${max_len} len=${#stuff}"
 # How many spaces we need to fill to keep
 # the length of stuff that will be shown?
 local fill_count=$((${index} - ${#stuff}))
 for ((index=0; index < fill_count; index++)); do
 stuff="${stuff} "
 done
 echo "${stuff}"
}
trim_method="roll" # Can be {trim or roll).
max_len=40 # Trim output to this length.
roll_speed=2 # Roll speed in chraacters per second.
np=$(ncmpcpp --current-song="{{{%a - }%t}}|{%f}")
if [ -n "$np" ]; then
 case "$trim_method" in
 "roll")
 np=$(roll_stuff "${np}" ${max_len} ${roll_speed})
 ;;
 "trim")
 np=$(echo "${np}" | cut -"$max_len")
 ;;
 esac
 echo "♫ ${np}"
fi
exit 0

打开 ~/.tmux.conf 文件, 修改状态栏配置如下:


set -g status-right '#{prefix_highlight} | %a %Y-%m-%d %H:%M | Mail: #(sh ~/.tmux/tmux-scripts/tmuxmail) | #(sh ~/.tmux/tmux-scripts/np_mpd.sh)'

主要参考最后一段参数配置, 最终效果显示如下图:

其它问题

如果 ncmpcpp 配置无误,但就是没有音乐,进入ncmpcpp,按下2或4,选择文件(文件夹),按下a,添加到playlist即可
