使用电子表格gem获取电子表格行数
这是我目前的工作代码：
require 'csv' require 'spreadsheet' folder_to_analyze = ARGV.first folder_path = File.join(Dir.pwd, folder_to_analyze) unless File.directory?(folder_path) puts "Error: #{folder_path} no es un folder valido." exit end def get_csv_file_paths(path) Dir.glob(path + '/**/*.csv').each do |f| yield f end end def get_xls_file_path(path) Dir.glob(path + '/**/*.xls').each do |f| yield f end end csv_files = [] excel_files = [] get_csv_file_paths(folder_path) { |f| csv_files << f } get_xls_file_path(folder_path) { |f| excel_files << f } puts "Se encontro #{csv_files.length + excel_files.length} archivos para procesar." puts '===========================================' puts 'Archivos CSV:' puts '===========================================' csv_files.each do |f| count = IO.readlines(f).size puts "Archivo: #{File.basename(f)} - Correos: #{count}" end puts '===========================================' puts 'Archivos Excel:' puts '===========================================' Spreadsheet.client_encoding = 'UTF-8' excel_files.each do |f| count = 0 book = Spreadsheet.open f book.worksheets.each do |sheet| sheet.each do |row| count = count + 1 end end puts "Archivo: #{File.basename(f)} - Correos: #{count}" end 电子表格行计算非常慢，每个Excel文件需要大约4秒才能计算。
有什么办法可以加速吗？ 它是否有隐藏的row_count属性？
没有必要迭代表单的行，只需在每个表中调用count就可以了：
excel_files.each do |f| count = 0 book = Spreadsheet.open f book.worksheets.each do |sheet| count += sheet.count end puts "Archivo: #{File.basename(f)} - Correos: #{count}" end
