Bug: RSpec/ExcessiveDocstringSpacing does not work well

[gruz0]

Hi guys,

I've found bug in RSpec/ExcessiveDocstringSpacing after updating to 2.5.0.

Before:

context 'when contains \' character ' do; end

After rubocop -a:

context 'when contains ' character' do; end

Result:

spec/test_spec.rb: E: Lint/Syntax: unexpected token tIDENTIFIER
(Using Ruby 2.7 parser; configure using TargetRubyVersion parameter, under AllCops)
    context 'when contains ' character' do; end
                             ^^^^^^^^^

Thanks for reporting.
Very similar to #1189.
The example you've provided is convincing enough that your code is absolutely fine, and the cop (or actually all cops that deal with descriptions) misbehave with escaped quotes.

I suggested one approach in #1189 (comment), but it might not apply to this other cop. Chances are we'll have to improve gems we depend on to fix this (rubocop, rubocop-ast, parser).

Would you like to contribute a fix?

I will try.

@G-Rath You might be interested, too. However, it's not ExcessiveDocstringSpacing to blame for this, as other cops suffer from such an incorrect autocorrection, too.

Quite unlikely that the fix is possible.
