uv.fs_scandir skips dotfiles

[高浩亮]

(sorry if i have opened a upstream issue here.)

in my use, uv.fs_scandir and uv.fs_scandir_next do not return files startswith ., i can neither find a flag in their function signature. is this feature addable?

This is a libuv limitation, see https://docs.libuv.org/en/v1.x/fs.html#c.uv_fs_scandir_next:

Note: Unlike scandir(3), this function does not return the “.” and “..” entries.

Edit: nevermind, it looks like you're looking for files starting with ., which fs_scandir_next should be picking up, this works for me.

To be clear, do you mean . and .. or files with a dot prefix (e.g. .something)?

thanks!

oh, sorry i just missed your comment. i mean to "files with a dot prefix (e.g. .something)".

That should work.

local uv = require('luv')

assert(uv.fs_scandir('.', function(err, req)
  assert(not err)
  local function iter()
    return uv.fs_scandir_next(req)
  end
  for name, ftype in iter do
    print(name, ftype)
  end
end))

uv.run()

from within a cloned luv repo gives me:
