class SyntaxSuggest::BlockExpand

This class is responsible for taking a code block that exists at a far indentaion and then iteratively increasing the block so that it captures everything within the same indentation block.

def dog
  puts "bow"
  puts "wow"
end

block = BlockExpand.new(code_lines: code_lines)

.call(CodeBlock.new(lines: code_lines[1]))

puts block.to_s # => puts “bow”

puts "wow"

Once a code block has captured everything at a given indentation level then it will expand to capture surrounding indentation.

block = BlockExpand.new(code_lines: code_lines)

.call(block)

block.to_s # => def dog

  puts "bow"
  puts "wow"
end
