类 SyntaxSuggest::ParseBlocksFromIndentLine

此类负责生成初始代码块,这些代码块随后将被扩展。

在猜测代码块时,最大的问题是意外地抓取了一个只包含“end”的代码块。在这个例子中

def dog
  begonn # mispelled `begin`
  puts "bark"
  end
end

以下行将被匹配(从下到上)

1) end

2) puts "bark"
   end

3) begonn
   puts "bark"
   end

此时它没有其他地方可以扩展,它将生成此内部代码作为块

def each_neighbor_block(target_line)
  scan = AroundBlockScan.new(code_lines: code_lines, block: CodeBlock.new(lines: target_line))
    .force_add_empty
    .force_add_hidden
    .scan_while { |line| line.indent >= target_line.indent }

  neighbors = scan.code_block.lines

  block = CodeBlock.new(lines: neighbors)
  if neighbors.length <= 2 || block.valid?
    yield block
  else
    until neighbors.empty?
      lines = [neighbors.pop]
      while (block = CodeBlock.new(lines: lines)) && block.invalid? && neighbors.any?
        lines.prepend neighbors.pop
      end

      yield block if block
    end
