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

➜  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 -c1-"$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
