This PR adds the class methods
File.empty?
(andFile.zero?
). I includedFile.zero?
becauseFile.empty?
in the docs links toFile.zero?
. https://ruby-doc.org/core-2.4.0_preview3/File.html#method-c-empty-3F (I'm guessing one is an alias of the other)See #4293 where feature is originally mentioned.
This PR gets the test
test_empty_p
in "test/mri/ruby/test_file_exhaustive.rb" to pass. I figured that I didn't need to add any other tests since this functionality is tested by the MRI tests. Let me know if I do need to add more tests.I did run into an issue while testing with just that file. If I ran just this command
I get an error about missing
assert_file
.I needed to add
require_relative 'envutil'
(which addsassert_file
) in order to run the tests. I would have included that change in this PR but it looks like those tests are generated based on the tests in Ruby and I wasn't sure if changes to those files would be overridden when new tests are brought in. That file is probably eventually required when the whole suite is run.This is my first time contributing to JRuby so let me know if there is something missing that I need to include.
