[issue18087] os.listdir don't show hidden option

[Dražen Lučanin]

Dražen Lučanin added the comment:

@Amaury Forgeot d'Arc - well, the '.' and '..' special files are
detected directly in the listdir code, so I don't think there is any
need to interleave this logic any deeper (such as os.path.ishidden).

@Antoine Pitrou - a one-liner, but it unnecessarily complicates the
code - an optional argument is a much more elegant solution in my
opinion. Regarding the *~ files - they are backup files, not hidden
files (same as e.g. #somefile# files that Emacs generates). These are
shown by ls, just hidden in some desktop environments.

Another point is that dotfiles are really something of a special case
(especially to programmers http://dotfiles.github.io/ ), because many
programs store configurations and special data inside and it makes
sense to allow users to omit these.

I know I could use glob, I am currently doing that, but it seems like
bad practice to switch to a different module that is also in the
standard library, just it has the "dotfile detection magic" and os
doesn't. The fact is that dotfiles do have special a meaning in Unix
operating systems and the os module documentation states that some
functionality is only tailored to Unix-based platforms
(http://docs.python.org/2/library/os.html):

    An “Availability: Unix” note means that this function is commonly
found on Unix systems. It does not make any claims about its existence
on a specific operating system.
