Python 从PYZ中的virtual dir获取GtkBuilder小部件的Gettext消息目录
是否有一种既定的方法将gettextPython 从PYZ中的virtual dir获取GtkBuilder小部件的Gettext消息目录,python,pygtk,gettext,glib,pyz,Python,Pygtk,Gettext,Glib,Pyz,是否有一种既定的方法将gettextlocale/xy/LC\u MESSAGES/*嵌入到一个数据库中？特别是让GTK自动小部件翻译从ZIP归档中提取它们 对于其他嵌入式资源，pkgutil.get_deta或inspect/get_source工作正常。但系统和Python依赖于bindtextdomain提供一个普通的localedir；没有资源或字符串等 因此，我无法设计出一个可行的、甚至是一点都不实用的解决方案： 虚拟gvfs/gio路径 现在使用archive://file%3A%2
locale/xy/LC\u MESSAGES/*pkgutil.get_detainspectget_sourcebindtextdomainlocaledirgvfsgio现在使用
archive://file%3A%2F%2Fmypkg.pyz%2Fmessages%2Flocaledir我认为PyInstaller就是这样工作的。但将某些东西捆绑为.pyz应用程序，却在每次调用时预先提取，这当然有点荒谬
.mo.po现在，手动读取消息目录或仅使用简单的dict将是一种选择。但仅适用于应用程序中的字符串。这也无法让Gtk/GtkBuilder隐式地获取它们。
因此，我必须手动遍历整个小部件树、标签、文本、内部小部件、标记和文本等。可能，但是meh
这将是超级富豪。但是当然，zip内容可以被访问
gvfs mount我发现了Shuck，所以我有点确定Gtk/PyGtk/GI中没有替代的小部件翻译机制。Gtk/Builder期望并且是gettext
也许有更可靠的方法吗？这是我的示例Glade/GtkBuilder/Gtk应用程序。我已经定义了一个函数

我必须承认，我不明白你所说的“油嘴滑舌的人和gettext的关系紧密”是什么意思。这些只是几个方便的宏，GLib中绝对没有任何东西强迫你使用它们或gettext。当然。这也是glib文档断言的（“不强制任何特定的本地化方法…”）。在Gtk的背景下，它只是不太可行。（即使重新编译是一种选择，宏方案也不允许例如ICU替换）。因此，如果您使用的不是gettext，那么您就必须迭代地翻译所有Gtk小部件。如果您的问题是GtkBuilder xml文件本地化与gettext绑定（这对我来说似乎是一个有效的问题），那么您应该清楚地说。当你暗示GLib（或Gtk应用程序代码）翻译与gettext有某种联系时，这会使问题更难理解：我猜我不是唯一一个挠头思考的人“这些东西与翻译的实际制作方式无关：GTK小部件不关心翻译，他们只希望得到翻译后的字符串”……修复了这个问题。我最初希望glib提供一个解决方法（gio路径和所有），因此怀疑这是一个解决方法。但GtkBuilder UI文件是一个更好的提示。找到一个预翻译其文本节点的替代方法可能比查找小部件挂钩更简单。是否有一种已建立的方法将gettext locale/xy/LC_MESSAGES/*嵌入PYZ捆绑包中？“已建立的方法”是什么意思？您可以或不能嵌入。如果我理解正确，你想将gettext
locale dir包含到应用程序pyz包中。对吗？哇，很多代码。仍在通读…看起来很实用。而且对其他用户也很有用。我将对其进行测试。-（已经看到了答案通知。所以请放松注释ping！）嘿，马里奥，你太酷了！非常感谢。编码快乐！
