# frozen_string_literal: true module SyntaxSuggest # This class is responsible for generating initial code blocks # that will then later be expanded. # # The biggest concern when guessing code blocks, is accidentally # grabbing one that contains only an "end". In this example: # # def dog # begonn # misspelled `begin` # puts "bark" # end # end # # The following lines would be matched (from bottom to top): # # 1) end # # 2) puts "bark" # end # # 3) begonn # puts "bark" # end # # At this point it has no where else to expand, and it will yield this inner # code as a block class ParseBlocksFromIndentLine attr_reader :code_lines def initialize(code_lines:) @code_lines = code_lines end # Builds blocks from bottom up 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 end end end end
