command-line-arguments

问题 This question already has answers here : converting string to tuple (3 answers) Closed 4 years ago . My requirement is to pass a tuple as command line argument like --data (1,2,3,4) I tried to use the argparse module, but if I pass like this it is receiving as the string '(1,2,3,4)' . I tried by giving type=tuple for argparse.add_argument , but is of no use here. Do I have to add a new type class and pass that to type argument of add_argument ? Update I tried the ast.literal_eval based on

问题 I'm trying to make a verbose flag for my Python program. Currently, I'm doing this: import click #global variable verboseFlag = False #parse arguments @click.command() @click.option('--verbose', '-v', is_flag=True, help="Print more output.") def log(verbose): global verboseFlag verboseFlag = True def main(): log() if verboseFlag: print("Verbose on!") if __name__ == "__main__": main() It'll never print "Verbose on!" even when I set the '-v' argument. My thoughts are that the log function needs

问题 I know that to use command line arguments, I have to do this. int main(int argc, char* argv[]) Now most of the documentation i read about taking in command line arguments explain the situation, something like this: Command-line arguments are given after the name of a program in command-line operating systems like DOS or Linux, and are passed in to the program from the operating system. So the only way i know to open my program, is to open it normally like i would do, either start debugging or

问题 I currently am tasked with creating some command-line helper utilities for our internal development team to use. However, I want to know the best practice for creating unix command-line tools. I have tried viewing git source code for an example of how to read parameters and display messages accordingly. However, I'm looking for a clear template for creating a tool, reading parameters safely, and displaying the standard "help" messages if a user types in an incorrect parameter or --help I want

问题 This command works START /b /wait "Dummy title" "C:\tmp\test runner2.bat" arg1 arg2 But both of these fails! START /b /wait "Dummy title" "C:\tmp\test runner2.bat" arg1 arg2 "arg 3" arg4 START /b /wait "Dummy title" "C:\tmp\test runner2.bat" arg1 arg2 "arg 3" The error is: 'C:\tmp\test' is not recognized as an internal or external command, operable program or batch file. Obviously it has something to do with " surounding the arguments, but why and how do I work around this? Related questions:

问题 I'm writing a little wrapper for an application that uses files as arguments. The wrapper needs to be in Unicode, so I'm using wchar_t for the characters and strings I have. Now I find myself in a problem, I need to have the arguments of the program in a array of wchar_t's and in a wchar_t string. Is it possible? I'm defining the main function as int main(int argc, char *argv[]) Should I use wchar_t's for argv ? Thank you very much, I seem not to find useful info on how to use Unicode

问题 Our OS X Java application which is launched by a shell script inside the MyApp.app bundle gets a strange command line parameter -psn_0_989382 when launched from the Finder, but not when launched directly from the Terminal. Where can I find information what this command line parameter is good for? 回答1: Mac OS X assigns a unique process serial number ("PSN") to all apps launched via GUI. It's used for identifying various processes and instances of executables. There's nothing I can really add

问题 I am embarking on my first attempt at utilizing a docker container. I have a python script that calls a couple API's and parses a file. The script took parameters for the URL of the server for the API, the API key, and the file path for the file to parse. I used argparse to handle these in the script. How do I get get these passed into Docker? I do not want to hard code anything as I am looking to hand this script off to an engineer who needs to run this periodically and take action based on

问题 Inside my Makfile I have the following, smktestrun: smktest @../projects/test.sh And I call this using: Make smktestrun But sometimes I need to pass an parameter/argument along with this file (test.sh) So basically I would like: test.sh -abc But if i just pass the argument in the Makefile itself, the argument is not taken as simply the sheel script is executed. So is there a way I could specify in the Makefile that an argument needs to be passed with that file? Thanks. 回答1: Something like

问题 I have created the simple Cocoa application (Mac OS X 10.6) and there have appeared the entry point: int main(int argc, char *argv[]) { return NSApplicationMain(argc, (const char **) argv); } and AppDelegate dummy: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { // how to get argc and argv? } and some other. How could I pass the argc and argv to my AppDelegate right way? 回答1: Use +[NSProcessInfo processInfo] and -[NSProcessInfo arguments] . In your application delegate
