SyntaxSuggest::Capture::BeforeAfterKeywordEnds

Shows surrounding kw/end pairs

The purpose of showing these extra pairs is due to cases of ambiguity when only one visible line is matched.

For example:

1  class Dog
2    def bark
4    def eat
5    end
6  end

In this case either line 2 could be missing an end or line 4 was an extra line added by mistake (it happens).

When we detect the above problem it shows the issue as only being on line 2

2    def bark

Showing “neighbor” keyword pairs gives extra context:

2    def bark
4    def eat
5    end

Example:

lines = BeforeAfterKeywordEnds.new(
  block: block,
  code_lines: code_lines
).call()
