Dir.entries returns an array of its content with "." and "..".

How about adding such new method or options?

Candidates for the methods or options?

I prefer a same option for both methods, but no concrete idea.

Dir.foreach and Dir.entries both support a second hash argument for options: as of 2.2.2, the docs only mention the :encoding key in the options hash.

Basing myself on the GNU ls util, I propose supporting an :ignore key in the optional hash argument.

We could have an API similar to this:

~~~
$ ls -a
.
..
.hidden_file
directory
file.bin

$ irb

irb:001> Dir.entries('.')
 => [".", "..", ".hidden_file", "directory", "file.bin"]
irb:002> Dir.entries('.', ignore: :almost_all)  # almost_all option name taken from GNU ls option name
 => [".hidden_file", "directory", "file.bin"]   # http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/ls.c#n4784
irb:003> Dir.entries('.', ignore: :directories)
=> [".hidden_file", "file.bin"]
irb:004> Dir.entries('.', ignore: :hidden)
=> ["directory", "file.bin"]

# Fancy proposal
irb:005> Dir.entries('.', ignore: /o/)
=> [".", "..", ".hidden_file", "file.bin"]
~~~

I very much like this. I just ran into this issue myself today having to remove `.` and `..` from `Dir.entries` output. 

I don't think the `ignore` option accepting a regex is fancy at all, it makes a ton of sense. An array should also be acceptable considering that `Dir.entries('.', ignore: %w[. ..])` would become equivalent to: 

```
Dir.entries('.') - %w[. ..]
```

I find it quite elegant, and certainly a lot more discoverable than GNU ls style arguments. :-)

`ignore: :almost_all` seems like that almost all files will be ignored and only '.' and '..' will be returned.

There is Pathname#children and Pathname#each_child.

How about Dir.children and Dir.each_child ?

The decision here is surprising given https://bugs.ruby-lang.org/issues/13789#note-3
