show lyric for deadbeef 显示歌词

修改自 http://forum.ubuntu.org.cn/viewtopic.php?f=21&t=339043 1楼 感谢wiewi
为简洁起见，我把主体和函数分开了。
我只是修改很少的一部分。函数我还没看完呢。:-(
比较难的可能是如何获取播放状态吧。
下面是 Deadbeef music player 的一个问题。

I haven’t looked at DeaDBeeF’s command line options, but is there one that will output its status? Then you’d just need a script with an if conditional:

!#/bin/bash
if `deadbeef –state` = “PLAY” #replace this with whatever code is necessary to find out if DeaDBeeF is playing
deadbeef –pause
else
deadbeef –play
endif

…and that’s your play/pause toggle.

我自己想办法解决了。

我真是笨啊。檢查播放狀態不一定要直接從程序給出的命令行中得出​。如果1秒前的播放位置和現在不同，那麽它就是“正在播放”

时间紧，暂时到此。水平有限，可能修改得不够好。

使用办法
把前面的代码保存为 lyric4deadbeef.sh 或者你喜欢的名字
后面的代码保存为 functions.main (和 lyric4deadbeef.sh同一个目录下)
然后

chmod +x  lyric4deadbeef.sh  functions.main

当然，不想分开也是可以的。把函数部分并在lyric4deadbeef.sh中的 #!/bin/bash 后面，去掉行 . functions.main
