为保证子程序的原汁原味，避免拉跨拙劣的翻译水平，所有子程序列表均保留英文说明。这里也没有对所有的子程序都进行验证，由于版本或抄写问题，可能会有所疏漏，欢迎指正。建议使用时再仔细研究对应类型的子程序，多多参考其他例子中参数的类型及设置。
ACC 子程序主要分为 5 大类：句柄（handle）、后继（next）、值变链接（VCL）、取值（fetch）、杂项（miscellaneous）、修改（modify）。

我需要在客户计算机上运行Ruby应用程序。通常需要几天才能完成(复制大备份文件)。问题是如果启用sleep，它会中断应用程序。否则，计算机将持续运行数周，直到我下次访问为止。有什么方法可以防止执行期间休眠并让Windows在执行后休眠吗？欢迎任何疯狂的想法;-) 最佳答案 Here建议使用SetThreadExecutionStateWinAPI函数，使应用程序能够通知系统它正在使用中，从而防止系统在应用程序运行时进入休眠状态或关闭显示。像这样的东西:require'Win32API'ES_AWAYMODE_REQUIRED=0x0

刚入门rails，开始慢慢理解。有人可以解释或给我一些关于在application_controller中编码的好处或时间和原因的想法吗？有哪些用例。您如何为Rails应用程序使用应用程序Controller？我不想在那里放太多代码，因为据我了解，每个请求都会调用此Controller。这是真的？ 最佳答案 ApplicationController实际上是您应用程序中的每个其他Controller都将从中继承的类(尽管这不是强制性的)。我同意不要用太多代码弄乱它并保持干净整洁的态度，尽管在某些情况下ApplicationContr
是否有类似“RVMuse1”或“RVMuselist[0]”之类的内容而不是键入整个版本号。在任何时候，我们都会看到一个可能包含5个或更多ruby的列表，我们可以轻松地键入一个数字而不是X.X.X。这也有助于rvmgemset。 最佳答案 这在RVM2.0中是可能的=>https://docs.google.com/document/d/1xW9GeEpLOWPcddDg_hOPvK4oeLxJmU3Q5FiCNT7nTAc/edit?usp=sharing-知道链接的任何人都可以发表评论
我是一个Rails初学者，但我想从我的RailsView(html.haml文件)中查看Ruby变量的内容。我试图在ruby中打印出变量(认为它会在终端中出现)，但没有得到任何结果。有什么建议吗？我知道Rails调试器，但更喜欢使用inspect来打印我的变量。 最佳答案 您可以在View中使用puts方法将信息输出到服务器控制台。您应该能够在View中的任何位置使用Haml执行以下操作:-puts@my_variable.inspect 关于ruby-on-rails-如何在我的R
如何检查Ruby文件是否是通过“require”或“load”导入的，而不是简单地从命令行执行的？例如:foo.rb的内容:puts"Hello"bar.rb的内容require'foo'输出:$./foo.rbHello$./bar.rbHello基本上，我想调用bar.rb以不执行puts调用。 最佳答案 将foo.rb改为:if__FILE__==$0puts"Hello"end检查__FILE__-当前ruby文件的名称-与$0-正在运行的脚本的名称。 关于ruby-检查是否
