Question

是否有可能使用像 optext 这样的文字来翻译 R 脚本。如果是, 如何翻译? 如果没有, 我还有什么其他选择?

Answer 1

You can use base::gettext/ngettext, base::bindtextdomain and tools::xgettext2pot functions.
For example:

myFunction <- function()
{  
  bindtextdomain("R-myProgram","/my/translation/dir")
  gettext("Hello",domain="R-myProgram")
}

然后,假设此函数位于一个路径为“/my/ dir/R/myfile.R” 的文件内,使用: tools::xgettext2poot ("/my/dir"), ,然后使用 msginit、 msgfmt 等创建 mo 文件 /my/ translation/dir/fr/LC_MESAGES/R-myProgram.mo 。我的功能() 现在应该打印“ Bonjour”, 而不是“ hello”, 如果您的语系是法语。



还有其他几点:


It seems like xgettext2pot assumes your project is a standard R package and looks only for *.R files inside the R/ subdirectory.
The domain argument seems to be by default the namespace of the function calling gettext()
stop(), message(), warning() and packupStartupMessage() are also detected by xgettext2pot. There is also a gettextf() function available as a sprintf-like variant of gettext().
Since the standard xgettext utility doesn t seem to support R syntax, and since one has to use tools::xgettext2pot, a couple of things will miss from the standard approach, such as message contexts (pgettext()), flags indicating printf-like strings and the possibility to write in-code comments for the translators (extracted by xgettext -c) without modifying the .pot file by hand.
