修改ubuntu tweak 爱壁纸默认下载目录

前几天用ubuntu tweak下载了一个很不错的壁纸,想保存起来,但是不知道它把壁纸下到什么地方去了,于是决定自己找一下

首先使用dpkg -L ubuntu-tweak查看ubuntu-tweak都在系统里安装了哪些文件:

......
/usr/share/pyshared/ubuntutweak/tweaks/lovewallpaperhd.py
/usr/share/pyshared/ubuntutweak/tweaks/sound.py
/usr/share/pyshared/ubuntutweak/tweaks/__init__.py
/usr/share/pyshared/ubuntutweak/tweaks/loginsettings.py
/usr/share/pyshared/ubuntutweak/tweaks/window.py
/usr/share/pyshared/ubuntutweak/tweaks/theme.py
/usr/share/pyshared/ubuntutweak/tweaks/workarounds.py
/usr/share/pyshared/ubuntutweak/tweaks/icons.py
/usr/share/pyshared/ubuntutweak/tweaks/workspace.py
/usr/share/pyshared/ubuntutweak/tweaks/misc.py
/usr/share/pyshared/ubuntutweak/tweaks/fonts.py
/usr/share/pyshared/ubuntutweak/tweaks/session.py
/usr/share/pyshared/ubuntutweak/tweaks/unity.py
/usr/share/pyshared/ubuntutweak/tweaks/nautilus.py
/usr/share/pyshared/ubuntutweak/clips
/usr/share/pyshared/ubuntutweak/clips/userinfo.py
.......

可以看到ubuntu-tweak是用python实现的,然后打开lovewallpaperhd.py,找到如下代码:

102     def on_wallpaper_downloaded(self, downloader):
103         os.rename(downloader.get_downloaded_file(), self.wallpaper_path)
104
105         wallpaper_setting = GSetting('org.gnome.desktop.background.picture-uri')
106         wallpaper_setting.set_value(GLib.filename_to_uri(self.wallpaper_path, None))
107
108         n = Notify.Notification.new(self.__title__, "Set wallpaper successfully!", 'ubuntu-tweak')
109         n.show()
110

105~106行设置壁纸,将"Set wallpaper successfully!"修改为"self.wallpaper_path,就可以显示出壁纸默认的下载路径: ~/.config/ubuntu-tweak/lovewallpaper.jpg

然后查找self.wallpaper_path的值:

29     def __init__(self):
30         TweakModule.__init__(self)
31
32         self.wallpaper_path = os.path.join(CONFIG_ROOT, 'lovewallpaper.jpg')
33         self.jsonman = JsonMan(Gdk.Screen.width(), Gdk.Screen.height())

13 from ubuntutweak.common.consts import CONFIG_ROOT
14 from ubuntutweak.modules  import TweakModule

使用ctags查看CONFIG_ROOT的值:

26 CONFIG_ROOT = os.path.join(GLib.get_user_config_dir(), 'ubuntu-tweak')
27 TEMP_ROOT = os.path.join(CONFIG_ROOT, 'temp')

在这里添加一个新的变量:

WALLPAPER_ROOT = '/home/wgh/Picture/wallpaper/'

然后ctrl-t返回lovewallpaper.py,在13行后边添加

from ubuntutweak.common.consts import WALLPAPER_ROOT

修改32行为:

self.wallpaper_path = os.path.join(WALLPAPER_ROOT, 'lovewallpaper.jpg')

现在tweak下载的壁纸就默认存放到~/Picture/wallpaper下了
