为什么这个 glob 不能用于我的服务器的 Rake FileList？

发布于 2024-12-26 02:00:54 字数 629 浏览 3 评论 0原文

我为什么从以下位置得到一个空文件列表：

  files = FileList.new("#{DEPLOYMENT_PATH}\**\*")

Where DEPLOYMENT_PATH is \\myserver\anndsomepath

如何从这样的服务器获取文件列表？这是 Ruby/Rake 的问题吗？

更新：

我尝试过：

  files = FileList.new("#{DEPLOYMENT_PATH}\\**\\*") 
  files = Dir.glob("#{DEPLOYMENT_PATH}\\**\\*") 
  files = Dir.glob("#{DEPLOYMENT_PATH}\**\*")

它就可以工作：

 //myserver/andsomepath

更新再次：如果我将服务器设置为：并获取如下文件，

  files = FileList.new("#{DEPLOYMENT_PATH}/**/*")

原文

How come I get an empty filelist from:

  files = FileList.new("#{DEPLOYMENT_PATH}\**\*")

Where DEPLOYMENT_PATH is \\myserver\anndsomepath

How to get a filelist from a server like this? Is this an issue of Ruby/Rake?

UPDATE:

I tried:

  files = FileList.new("#{DEPLOYMENT_PATH}\\**\\*") 
  files = Dir.glob("#{DEPLOYMENT_PATH}\\**\\*") 
  files = Dir.glob("#{DEPLOYMENT_PATH}\**\*")

UPDATE AGAIN: It works if I put server as:

 //myserver/andsomepath

and get files like this:

  files = FileList.new("#{DEPLOYMENT_PATH}/**/*")

Ruby 的 File.join 旨在成为您处理文件路径时的帮手，通过以独立于系统的方式构建它们：

File.join('a','b','c')
=> "a/b/c"

因此：

DEPLOYMENT_PATH = File.join('', 'myserver', 'andsomepath')
=> "/myserver/andsomepath"

Ruby 通过感知操作系统来确定文件路径分隔符，并且假设自动提供正确的值。在 Windows XP、Linux 和 Mac OS 上：

File::SEPARATOR
=> "/"

File.join(DEPLOYMENT_PATH, '**', '*')
=> "/myserver/andsomepath/**/*"

虽然您可以忽略该帮助程序，但它可以让您的生活更轻松。因为您正在针对服务器工作，所以您可能需要查看 File::ALT_SEPARATOR，或者只是重新分配给 SEPARATOR 并忽略警告，让 Ruby 完成剩下的工作。

Ruby' File.join is designed to be your helper when dealing with file paths, by building them in a system-independent way:

File.join('a','b','c')
=> "a/b/c"

So:

DEPLOYMENT_PATH = File.join('', 'myserver', 'andsomepath')
=> "/myserver/andsomepath"

Ruby determines the file path separator by sensing the OS, and is supposed to automatically supply the right value. On Windows XP, Linux and Mac OS it is:

File::SEPARATOR
=> "/"

File.join(DEPLOYMENT_PATH, '**', '*')
=> "/myserver/andsomepath/**/*"

While you can ignore the helper, it is there to make your life easier. Because you are working against a server, you might want to look into File::ALT_SEPARATOR, or just reassigning to SEPARATOR and ignore the warning, letting Ruby do the rest.

如果您

Dir.glob("#{DEPLOYMENT_PATH}\**\*")

编辑：会发生什么？我认为 Ruby 更喜欢您执行 Unix 风格的斜杠，即使您在 Windows 上也是如此。我认为其基本原理是，相同的代码在 Unix 和 Windows 上运行会更好，即使它在 Windows 上看起来很奇怪。

tl;dr：如果它适用于 / 但不适用于 \，则使用有效的方法。

What happens if you do

Dir.glob("#{DEPLOYMENT_PATH}\**\*")

Edit: I think Ruby prefers you doing Unix-style slashes, even when you're on Windows. I assume the rationale is that it's better for the same code to work on both Unix and Windows, even if it looks weird on Windows.

tl;dr: If it works with / but not with \, then use what works.
