    这个主要用来记录一些开发动态和相关的信息,其实目前看来用途还不算特别的大,因为我的开发速度、时间、精力、能力实在有限,这个项目也是只有
我一个人知道,基本等于无人问津……
    不管怎么样,希望这个项目以后能够做好、做大,给中国Linuxer提供一个好的播放器,从而增加Linux在中国的普及程度!

Subject: Re: Exaile-cn开发小组
今天没怎么写这玩意,说一下下一步的计划:
1.用glade做一个显示歌词的界面,需要有4-5行,其中突出显示一行,作为同步使用,这个是字体方面的功夫,具体要用的,应该是
pango.FontDescription()这个东西和textView.modify_font()
2.还要做一个歌词选择的界面,当初先多个歌词时,用来选择(现在默认是选择一个)……这个应该不难实现
3.存储歌词的功能,就是一个保存吧,从最简单的直接保存做起就可以了
4.安装功能,目前这个先不考虑,具体的安装功能,实际上现在看来,就是将歌词插件拷贝到插件目录下,让exaile支持中文……
5.错误处理,有很多的try,expect没有写,这是个大问题,主要是我不太会使用这个……以后再写的时候,工作量会很大,现在写又没有精力……苦
恼啊

详细的说一下计划1:
    界面上要有五行歌词,自动载入(当没有歌词时,可以直接弹出一个框显示没有歌词……)一行结束换一行,其中一行的字体设置与别的不同,使得这一
行可以突出显示,作为当前行,所以要有一个时间工具,不断的获取播放的歌词的时间,用来同步歌词

一点对lrc文件的成果,主要就是使用正则表达式,抓出所有的时间来……之前看了些代码跟lrc文件,发现并不是所有的lrc都是一行一个时间的,例如
我去2000年里面,就是一行有两个时间,这个据我猜测,应该是那种repeat……,用findall()列举所有的时间
[04:20.00][01:57.00]泥锅泥碗你滚蛋
[04:20.00][01:57.00]sdfsdga
bill@bill-desktop:~$ python
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import re
>>> part = r'\[[0-9]+:[0-9]+\.[0-9]+\]'
>>> parOb = re.compile(part)
>>> m = parOb.findall('[04:20.00][01:57.00]sdfsdga')
>>> m

['[04:20.00]', '[01:57.00]']
>>> m = parOb.match('[04:20.00]')
>>> m

<_sre.SRE_Match object at 0xb7d5e218>

['[04:20.00]', '[01:57.00]']
下一步,应该继续用正则表达式,抓出时间来,然后加起来,得出毫秒的时间(因为ms记得exaile里面的时间都是毫秒的)
稍候,再写这段

准备转投exaile3,刚刚看到了launchpad里面的exaile项目(https://launchpad.net/exaile),上面有
张路线图,看来到今年9月份,3就要正式替代2了,https://launchpad.net/exaile/+series。ms8月20号就有
3.0出来了……,所以,现在,必须放弃2了!

值得称赞的,在exaile3中,对id3 tags的读取的操作是通过一个统一的文件进行的,这样就方便了许多
exaile2中是把不同的文件类型的音乐用不同的文件操作的,这样比较混乱!哈哈,2to3,进步不小

整理工作暂时到此为止,现在基本上大部分功能都已经实现了,只剩下三个要做的功能:字体选择、手动搜索、对手动调整时间的反应(这个问题最重要,不太好
解决,主要是不想使代码太复杂)
歌词插件一直是尽量减少对CPU的使用,从而增大反应速度的所以,不想让它太大了

下一步想增加一些Mp3文件改名功能(这个在千千静听里也有)
