带有Dir ['*']的Ruby列表目录，包括点文件，但不包括.和 [英] Ruby list directory with Dir['*'] including dotfiles but not . and

问题描述

如何获取Dir['*']包含点文件(例如.gitignore)，但不包括.和..?

How do I get Dir['*'] to include dotfiles, e.g., .gitignore, but not . and ..?

即，是否有更好的方法:

I.e., is there a better way to do:

`ls -A`.split "\n"

也许用Dir?以下解决方案比较接近，但都包括.& ..:

perhaps with Dir? The following solutions are close but both include . & ..:

Dir.glob('*', File::FNM_DOTMATCH)
Dir['{.*,*}']

因此，以下工作有效:

Dir.glob('*', File::FNM_DOTMATCH) - ['.', '..']

但是，还有更好的方法吗?

But, is there still a better way to do this?

推荐答案

您不能使用

您可以摆脱.& ..轻松:

You can get rid of the . & .. easily:

Dir.glob("*", File::FNM_DOTMATCH).tap { |a| a.shift(2) }

但是我认为最好还是坚持原来的方式:

But I think it’s probably best to stick with your original way:

Dir.glob("*", File::FNM_DOTMATCH) - %w[. ..]

(除其他方法外)

但是，如果您不需要比*更复杂的glob，请 grep 需要更多过滤的结果):

However, if you don’t require a more sophisticated glob than *, Dir#children may be all you need (can always further filter/grep the results if more filtering is needed):

Dir.children('.')
