class SyntaxSuggest::Capture::FallingIndentLines
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
