如何在ruby的交互模式下查看/保存/加载工作空间

因此,这里有一种技术,可以将IRB会话中输入的命令附加到主目录中的文件中(ruby talk的想法:58931)。将以下内容放入您的.irbrc中:

module Readline
  module History
    LOG = "#{ENV['HOME']}/.irb-history"

    def self.write_log(line)
      File.open(LOG, 'ab') {|f| f << "#{line}
"}
    end

    def self.start_session_log
      write_log("
# session start: #{Time.now}

")
      at_exit { write_log("
# session stop: #{Time.now}
") }
    end
  end

  alias :old_readline :readline
  def readline(*args)
    ln = old_readline(*args)
    begin
      History.write_log(ln)
    rescue
    end
    ln
  end
end

Readline::History.start_session_log

sketches gem 它允许您在首选编辑器中的临时文件中原型化代码。我认为它不支持快照。

>> sketch
# Write some code in an editor ...

# Lists sketches and their code
>> sketches

# Reopens the first sketch from above
>> sketch 1
