3 月，跳不动了？>>> Python 有两个内建的模块用于处理命令行参数：一个是 getopt，《Deep in python》一书中也有提到，只能简单处理命令行参数；另一个是 optparse，它功能强大，而且易于使用，可以方便地生成标准的、符合Unix/Posix 规范的命令行说明。示例 from optparse import OptionParser parser = OptionParser() parser.add_option("-p", "--pdbk", action="store_true", dest="pdcl", default=False, help="write pdbk data to oracle db") parser.add_option("-z", "--zdbk", action="store_true", dest="zdcl", default=False, help="write zdbk data to oracle db") (options, args) = parser.parse_args() if options.pdcl==True: print 'pdcl is true' if options.zdcl==True: print 'zdcl is true' add_option用来加入选项

问题 I can not seem to be able to read from config file multitoken options like I can from command line. What is the syntax for the config file? This is how the option description is added: //parser.cpp - - - po::options_description* generic; generic=new po::options_description("Generic options"); generic->add_options() ("coordinate",po::value<std::vector<double> >()->multitoken(),"Coordinates (x,y)"); After which I parse command and config-files. On command line '--coordinate 1 2' works. However,

问题 I don't know ruby very well, but I'm trying to add some functionality to this script a co-worker wrote.

问题 I have an application that allows you to send event data to a custom script. You simply lay out the command line arguments and assign what event data goes with what argument. The problem is that there is no real flexibility here. Every option you map out is going to be used, but not every option will necessarily have data. So when the application builds the string to send to the script, some of the arguments are blank and python's OptionParser errors out with "error: --someargument option
