Layout/SpaceInsideArrayLiteralBrackets should correct empty lines

[ayacai115]

Expected behavior

foo = [
]
foo

When I rubocop -a, rubocop corrects the empty line.

foo = []
foo

Actual behavior

When I rubocop -a...

Offenses:

sample.rb:1:7: C: [Corrected] Layout/SpaceInsideArrayLiteralBrackets: Do not use space inside empty array brackets.
foo = [ ...
      ^

1 file inspected, 1 offense detected, 1 offense corrected

But it's not actually corrected and I keep getting this message.
I think this is a bug.

Steps to reproduce the problem

$ vi sample.rb
foo = [
]
foo

$ rubocop -a sample.rb
Inspecting 1 file
C

Offenses:

sample.rb:1:7: C: [Corrected] Layout/SpaceInsideArrayLiteralBrackets: Do not use space inside empty array brackets.
foo = [ ...
      ^

1 file inspected, 1 offense detected, 1 offense corrected

But it's not corrected and I get the same message again.

$ rubocop -a sample.rb
Inspecting 1 file
C

Offenses:

sample.rb:1:7: C: [Corrected] Layout/SpaceInsideArrayLiteralBrackets: Do not use space inside empty array brackets.
foo = [ ...
      ^

1 file inspected, 1 offense detected, 1 offense corrected

RuboCop version

Same issue here, a different proposal though: #5585

I'm trying to create a PR to fix this bug... but if anybody can, that'd be very helpful.

@ayacai115 This seems to do the trick: master...buehmann:empty-array-literal/7509 – Could you take it from there? We need a spec for this case and a changelog entry for a full PR.

[ayacai115]

@buehmann Great! I'll add a spec and a changelog entry.
