Description

The documentation says that File.extname returns the portion of the filename after the period, while the actual output includes the period. Update the documentation to reflect this.

Good catch!

There are a few special cases:

  • dotfiles (e.g.: ".hidden") have "" for extname and ".hidden" for basename.
  • files ending with a dot report "" as extname (done by rb_file_s_extname())
  • looking at ruby_enc_find_extname(), the part after ':' is not kept for NTFS paths.

Eregon, what do you suggest?

I sorta feel like covering every special case would be bad, but maybe add a few more examples?

Drbrain, could you handle this?

I think adding documentation for dotfiles and files ending with a dot would be sufficient.

I don't think covering filesystem-specific behavior is necessarily useful.

Noah, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.


  • file.c (File.extname): Documentation for extname on dotfiles and
    files ending with a dot. Also, added example for this.
