问题 We have a desktop application installed through a windows installer (msi), and we want to add a custom action that relaunches the .exe when we have pass LAUNCH_APP=1 to the cmd . So I have a vbs script that launch a bat file that launch install the msi (major upgrade): vbs script: Set WshShell = CreateObject("WScript.Shell") Const TemporaryFolder = 2 Dim fso: Set fso = CreateObject("Scripting.FileSystemObject") Dim tempFolder: tempFolder = fso.GetSpecialFolder(TemporaryFolder) WshShell.Run

问题 I have gone through the sys documentation, however there is something that is still unclear to me. I have looked for some similar question on stackoverflow, but I haven't find anything useful (clearly any reference is appreciated!). I want to create a script - say foo.py - in which I want pass from 3 to 6 arguments: $ python foo.py arg1 arg2 arg3 The first 3 arguments must be given in any case; the last 3 arguments are used in a function that have default argument values if nothing is passed.

问题 I have a Deno app, that I wish to pass some command line args to. I searched the manual, but found nothing. I tried to use the same commands used in Node.js, assuming they might be sharing some for the std libraries, but it didn't work as well. var args = process.argv.slice(2); // Uncaught ReferenceError: process is not defined Any suggestions? 回答1: You can use Deno.args to access the command line arguments in Deno. To try it create a file test.ts : console.log(Deno.args); And run it with

问题 I'm trying to pass file list to my python script via argument: python script.py -o aaa -s bbb "filename.txt" "filename2.txt" "file name3.txt" Unfortunately ArgumentParser is ignoring quotes and instead of giving list of 3 files it gives me list of 4 elements as followed: 1) "filename.txt" 2) "filename2.txt" 3) "file 4) name3.txt" It completely ignores quotes. How to make it work with quotes? 回答1: Hard without seeing what you're using or any code. Your shell may be interfering, you may need to

问题 I need my program to get several arguments from command line, the syntax is as follows: getpwd -l user1 user2 ... -L -X -S... So, I need to get the users behind the -l option. I tried using getopt , but without much luck, it only works when I place the other options before the -l : getpwd -L -X -S ... -l user1 user2 ... My code (for -l and -S ): while((c = getopt(argc, argv, "l:S")) != -1){ switch(c){ case 'l': index = optind-1; while(index < argc){ next = strdup(argv[index]); /* get login */

问题 I have an issue that's nearly identical to the one outlined here (Console app not parsing correctly args with white spaces) but that answer has no bearing on my situation. I'm receiving arguments to my simple program that are paths and path+filenames with potentially lots of spaces in them. What's happening is that spaces in the paths are generating many more arguments than I actually have. I was manually reconstructing what I needed by passing through the args array, but I discovered today

问题 Following this post, where I have found a temporary workaround for my other problem, I want to know if I can replace the int argc, char** argv with a std::vector<std::string> variable/object. Consider the imaginary code: #include <iostream> #include <CloseLibrary> void someFunction(int argc, char** argv){ for (int i = 0; i < argc; ++i) { std::cout << argv[i] << std::endl; } } int myFunc(int argc, char** argv){ someFunction(argc, argv); return 0; } where the CloseLibrary is a closed library
