command-line-arguments

问题 I am using command line options in my grunt script: http://kurst.co.uk/transfer/Gruntfile.js However the command grunt --vers:0.0.1 always returns 'undefined' when I try to get the option: var version = grunt.option('vers') || ''; Can you help me get this working ? I tried different (CLI) commands: grunt vers:asd grunt -vers:asd grunt vers=asd as well as using : grunt.option('-vers'); grunt.option('--vers'); But no luck so far. Hopefully I am missing something simple. This is my package.js

问题 I had a terrible time with file input from command line arguments last semester and I need to utilize it for an exercise that I am working on. I have coded a simple shell just to get it working: prob_5.c #include <stdio.h> int main(int argc, char *argv[]) { int i; FILE *fp; int c; for (i = 1; i < argc; i++) { fp = fopen(argv[i], "r"); if (fp == NULL) { fprint(stderr, "cat: can't open %s\n", argv[i]); continue; } while ((c = getc(fp)) != EOF) { putchar(c); } fclose(fp); } return 0; } I can't

问题 I've written a small test suite in Python's unittest: class TestRepos(unittest.TestCase): @classmethod def setUpClass(cls): """Get repo lists from the svn server.""" ... def test_repo_list_not_empty(self): """Assert the the repo list is not empty""" self.assertTrue(len(TestRepoLists.all_repos)>0) def test_include_list_not_empty(self): """Assert the the include list is not empty""" self.assertTrue(len(TestRepoLists.svn_dirs)>0) ... if __name__ == '__main__': unittest.main(testRunner=xmlrunner

问题 I'm building an application whose usage is going to look something like this: application --command --option1=? --option2=2? Basically, there can be any number of options, but only one command per instance of the application. Similar to the way git works. Now, I thought I'd write it in C++ to get some boost and stl experience and have a go with a few of those design patterns I keep reading about. So, I implemented this: class Action { public: void AddParameter(std::string key, boost::any p);

问题 Trying to provide a dirty workaround for my problem described here, I want to retrieve the name of the currently executed module by reading the command line. But it looks like a higher power tries to prevent me from achieving my goal.. When I start my_module via python3 -m my_module sys.argv happens to be ['-m'] Is this correct? Shouldn't it be either [] , ['my_module'] or even ['-m', 'my_module'] ? What can I do here to get 'my_module'? Note : I know, I can always access __name__ or _

问题 All, I am currently using JUnit 4 for writing test cases. I am fairly new to JUnit and finding it difficult to test my main class which takes arguments. I have specified the arguments to my JUnit test class by: 1 > Right click JUnit test class 2 > Goto Run As -> Run Configurations 3 > Select the Arguments tab and specify a value (I have entered an invalid argument i.e. the main class expects the command line argument to be converted to an int and I am passing a String value that cannot be

问题 The code below accepts command line arguments for mode such as -m fizz and -m fizz bazz . This, as expected, passes the arguments to the main function as ['fizz', 'bazz'] (for the second example above). It seems user-unfriendly to pass command line arguments with spaces, so I'd like argparse to accept a comma-separated list e.g. -m fizz,bazz or -m ['fizz','bazz'] . How can I modify the code below to do this? Thanks! import agrparse ... parser.add_argument("-m", "--mode", nargs="*", default=[

问题 This question already has answers here : What is the %* or $* argument list equivalent for VBScript? (2 answers) Closed 3 years ago . How do I get the entire command line in a .vbs file? I'm looking to process it myself, with all special characters/quotes still intact. For example, the command: cscript.exe example.vbs /month:April /price:500 "Joe Smith" is "our" guy I am NOT interested in: WScript.Arguments.Named.Item("month") = April WScript.Arguments.Item(2) = Joe Smith Dim StrArgs For Each

问题 I am trying to rename a set of pdf files in my desktop using a simple python script. I am somehow not very successful. My current code is : import os,subprocess path = "/Users/armed/Desktop/" for file in os.listdir(path) command = ['mv', '*.pdf' , 'test.pdf'] // mv Command to rename files to test.pdf subprocess.call(command) The output i get for this code is 1 and the files are not renamed. The same command works when executed in the terminal. I am using a Mac (if that helps in any way) 回答1:
