[issue18087] os.listdir don't show hidden option
Dražen Lučanin added the comment: I created a first version of the patch (attached as a remote hg repo). It would enable users to exclude hidden files with: import os print(os.listdir(path='.', show_hidden=False)) while still keeping full backwards compatibility, since show_hidden is an optional argument set to True by default. @Dmi Baranov - well, I think aiming at the ls functionality would be a good first step (so we would mimic the -a flag, as explained in the manpage). As far as Windows, that's not too clear, I agree. So far I only added the functionality to the posix_listdir. Do you think this should act the same on Windows - i.e. hiding dotfiles? -- hgrepos: +193 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18087 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Amaury Forgeot d'Arc added the comment: The concept of hidden file depends on the platform, and is independent of the listdir() function. The first thing is to agree on an implementation of the hidden property, and expose it as os.path.ishidden. Then we can consider an option to os.listdir. But do we need it? today it does not have any option at all, like isfile or isdir which would be more useful. -- nosy: +amaury.forgeotdarc ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18087 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou added the comment: I don't really understand, since this is an easy one-liner: [n for n in os.listdir(...) if not n.startswith(.)] Also, as mentioned, what you want to hide is not necessarily well-defined. For example, under Unix you might want to hide *~ files. So I don't think os.listdir() should grow such an option, it's up to user code to decide what should be displayed / reported to the user. (or in other words: while Python provides filesystem-access functions, Python is not a shell) -- nosy: +pitrou ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18087 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Dmi Baranov added the comment: Also, as mentioned, what you want to hide is not necessarily well-defined. For example, under Unix you might want to hide *~ files. Yes, and instead of adding another parameters, something like that: os.listdir(path, show_hidden=False, hidden_files_mask='*~', but_show_directories=True, something_etc=None) I suggest leaving the hidden files logic outside of stdlib (in the end-user code).

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

[issue18087] os.listdir don't show hidden option
New submission from Dražen Lučanin: I would like to be able to list a directory, but without showing hidden files. Currently, as discussed in a SO question [1], one has to either code this manually or resort to other libraries (glob). This functionality should be available in the os module.

Dmi Baranov added the comment: So, I'm having a .gitignore file on Windows. Its hidden or not? In other words, only your code feel the difference in hidden files policy. BTW, Mas OSX using two ways - dotfiles and invisible flags in Finder: $ chflags hidden i-am-hidden-now.txt (but 'ls' showing it) -- nosy: +dmi.baranov ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18087 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
