在 FreeBSD 上创建一个新的语言环境

  • 772

我想在 FreeBSD 上创建一个新的语言环境。我以为我可以只复制现有的一个，/usr/share/locale但显然它不是那么简单。

en_US.UTF-8首先，我只是创建了一个语言环境的副本。

$ sudo cp -R /usr/share/locale/en_US.UTF-8 /usr/share/locale/en_DK.UTF-8

我正在用 mosh 测试我的设置，所以使用标准en_US.UTF-8一切都很好：

$ LC_ALL=en_US.UTF-8 PATH_LOCALE=/usr/share/locale mosh xyz.example.org

但是，如果我尝试使用新创建的en_DK.UTF-8语言环境，我会收到以下错误：

$ LC_ALL=en_DK.UTF-8 PATH_LOCALE=/usr/share/locale mosh xyz.example.org
The locale requested by LC_ALL=en_DK.UTF-8 isn't available here.
Running `locale-gen en_DK.UTF-8' may be necessary.

mosh-server needs a UTF-8 native locale to run.

Unfortunately, the local environment ([no charset variables]) specifies
the character set "US-ASCII",

The client-supplied environment (LC_ALL=en_DK.UTF-8) specifies
the character set "US-ASCII".

sh: warning: setlocale: LC_ALL: cannot change locale (en_DK.UTF-8)
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_DK.UTF-8
LC_CTYPE="en_DK.UTF-8"
LC_NUMERIC="en_DK.UTF-8"
LC_TIME="en_DK.UTF-8"
LC_COLLATE="en_DK.UTF-8"
LC_MONETARY="en_DK.UTF-8"
LC_MESSAGES="en_DK.UTF-8"
LC_PAPER="en_DK.UTF-8"
LC_NAME="en_DK.UTF-8"
LC_ADDRESS="en_DK.UTF-8"
LC_TELEPHONE="en_DK.UTF-8"
LC_MEASUREMENT="en_DK.UTF-8"
LC_IDENTIFICATION="en_DK.UTF-8"
LC_ALL=en_DK.UTF-8
Connection to xyz.example.org closed.

    看来您正在 FreeBSD 上尝试 Linuxism。在 FreeBSD 上，您应该使用登录类

    我应该将我的语言环境设置为什么以及这样做的含义是什么？.

    该答案中您可以忽略的部分是“安装语言环境”。FreeBSD 安装了所有常见的语言环境。您可以通过以下方式验证这一点

    locale -a

    但是您可能声称您尝试修改语言环境并进行设置。这就是我所说的 Linux 主义。人们在不了解实际发生的情况下将语言环境添加到 linux，然后设置 LC_ALL。语言环境定义了一组LC_*变量。LC_ALL然后用于覆盖那些！

    在 FreeBSD 上，更改用户（或系统）区域设置的首选方法是使用22.2.1.1。登录类方法。您也可以在此处更改系统范围的默认值。

    LC_ALL 只有在您想（强制）否决任何和所有其他 LC_* 设置时才应设置。您可能认为您正在设置“语言环境”，LC_ALL但实际上您只是设置LANG为LANG=en_DK.UTF-8. 那不是一种有效的语言，你应该把它留给Unicode CLDR Project。有关这方面的更多信息，请查看“LC_ALL=C”做什么？

    我的问题是你不想发明你自己的新语言。但是从您选择的组合中，我的猜测是您希望系统表现得像丹麦（DK）系统，但与您说英语。为此，您可以将LC_*变量与热量内容混合并匹配。

    例子：

    LANG=en_US.UTF-8
LC_CTYPE="da_DK.UTF-8"
LC_COLLATE="da_DK.UTF-8"
LC_TIME="da_DK.UTF-8"
LC_NUMERIC="da_DK.UTF-8"
LC_MONETARY="da_DK.UTF-8"
LC_MESSAGES="en_US.UTF-8"

    如果您不想设置登录类（出于某种原因），那么您仍然应该坚持使用 CLDR 定义的变量。这将为您提供最便携的结果：

    $ LC_ALL=C LANG=en_US.UTF-8 LC_CTYPE=da_DK.UTF-8 LC_COLLATE=da_DK.UTF-8 LC_TIME=da_DK.UTF-8 LC_NUMERIC=da_DK.UTF-8 LC_MONETARY=da_DK.UTF-8 LC_MESSAGES=en_US.UTF-8 mosh xyz.example.org
/usr/local/bin/mosh: could not get canonical name for xyz.example.org: hostname nor servname provided, or not known
ssh_exchange_identification: Connection closed by remote host
/usr/local/bin/mosh: Did not find remote IP address (is SSH ProxyCommand disabled?).
$

    如果它是您想要常用的语言环境设置，那么您可以使用登录类进行设置。请参阅 FreeBSD 手册或我对SSH to FreeBSD in UTF-8 的回答

    我认为你的答案在上面的某个地方。但是，如果我们逐字询问，那么 FreeBSD 当前将在 13.0 中添加 UTF-8 C 语言环境（请参阅提交 r340144）。如果您真的想了解如何添加新语言环境，请查看介绍 C.UTF-8 语言环境

    更新

    该目录/usr/share/locale/*只是一个目录。如果您像 Q 中那样进行逐字复制，那么 FreeBSD 11.2 上就可以工作。我仍然建议使用详细LC_ALL或登录类。目前我认为问题在于“胖手指”。

    该目录包含符号链接和定义文件。这些文件可以由localdef创建，它在 2015 年取代了 mklocale 。

    如果您不想更改实际的排序顺序，那么您可以链接到具有“正确”排序顺序的语言 - 或简单地复制文件。PATH_LOCALE=/usr/share/locale是隐含的，因为它是默认值。

    我在我的系统上逐字复制到test和en_DK.UTF-8. 他们locale -a立即出现。两者都按预期工作：

    $ locale -a | grep -e en_DK -e test
en_DK.UTF-8
test
$ LC_ALL=test mosh xyz.example.org
/usr/local/bin/mosh: could not get canonical name for xyz.example.org: hostname nor servname provided, or not known
ssh_exchange_identification: Connection closed by remote host
/usr/local/bin/mosh: Did not find remote IP address (is SSH ProxyCommand disabled?).
$ LC_ALL=test /bin/sh
$ locale
LANG=
LC_CTYPE="test"
LC_COLLATE="test"
LC_TIME="test"
LC_NUMERIC="test"
LC_MONETARY="test"
LC_MESSAGES="test"
LC_ALL=test
$ exit
