SyntaxSuggest::Capture::FallingIndentLines

Class

Shows the context around code provided by “falling” indentation

If this is the original code lines:

class OH
  def hello
    it "foo" do
  end
end

And this is the line that is captured

it "foo" do

It will yield its surrounding context:

class OH
  def hello
  end
end

Example:

FallingIndentLines.new(
    block: block,
    code_lines: @code_lines
).call do |line|
  @lines_to_output << line
end
