command-line-arguments

问题 I run the following command in a Windows batch file: start "" "C:\PDF Viewer\PDFXCview.exe" /A "page=1&zoom=33.3" "G:\my pdfs\file 1.pdf" /A "page=4&zoom=55.5" "G:\my pdfs\file 2.pdf" The works perfectly fine and opens both PDF files using their respective parameters. However, to make the process cleaner, I would like to start using variables in place of the PDF files (and even the PDF viewer executable). However, when I use variables, only the first PDF file opens: set PDF1="G:\my pdfs\file

问题 launchd passes the -psn_... parameter to an application. If I understand correctly, this parameter tells me the Process Serial Number, right? But why is it passed? Isn't it just the same as what I would get with GetCurrentProcess? If so, I don't understand why it is passed as a parameter. If that is something different, then what is this parameter and what can I do with it? Note that there is a very related question about the meaning of PSN. However, that doesn't really answers the question

问题 I am familiar with python before and now I am trying to learn common lisp and using ccl(clozure common lisp)under windows system. I found that there is not a convenient way to run lisp file as python. So i write a bat file to compile and run a lisp file. @echo off set lisp_filename=%~1 set ccl_path=D:\_play_\lispbox-0.7\ccl-1.6-windowsx86\wx86cl.exe IF "%PROCESSOR_ARCHITECTURE%" == "x86" ( set fsl_filename=%lisp_filename:.lisp=.wx32fsl% ) ELSE ( set ccl_path=%ccl_path:wx86cl=wx86cl64% set fsl

问题 I want to print all command line arguments as a single string. Example of how I call my script and what I expect to be printed: ./RunT.py mytst.tst -c qwerty.c mytst.tst -c qwerty.c The code that does that: args = str(sys.argv[1:]) args = args.replace("[","") args = args.replace("]","") args = args.replace(",","") args = args.replace("'","") print args I did all replaces because sys.argv[1:] returns this: ['mytst.tst', '-c', 'qwerty.c'] Is there a better way to get same result? I don't like

问题 I have to write a command-line interface and I've seen I can use docopt and argparse . I would like to know what are the main differences between the two so that I can make an enlightened choice. Please stick to the facts. I don't want Wow. docopt. So beautiful. Very useful. 回答1: Docopt parses a doc string, whereas argparse constructs its parsing by creating an object instance and adding behaviour to it by function calls. Example for argparse: parser = argparse.ArgumentParser() parser.add

问题 I'm trying to figure out which is the command line arguments used by Visual Studio when you run the MsTest tests, I guess it starts with: MSTest.exe /testmetadata:%SolutionName%.vsmdi /testlist: But I couldn't figure out how to fill the testlist parameter, because both the test list name and id get the following error: The test list path 8c43105b-9dc1-4917-a39f-aa66a61bf5b6 cannot be found. An error occurred while executing the /testlist switch. 回答1: I'm trying to figure out which is the

问题 I have an OpenEmbedded environment using bitbake to do some builds. I wanted to get something "interactive" going on where bitbake would pause and ask for input then continue with the build but I've found out that's not possible. Since I can't do that I'm looking for some way to pass in extra flags for the build. Is there any way to pass in flags to a bitbake build sort of like gcc's -D option? ie: bitbake -Dfoo=bar oe-myimage Thus during the build process of oe-myimage the variable foo will

问题 Whenever you declare the main method in a class, you always have to do a String array called "args". What's the point? Unless I live under a rock, command line agruments in Java are barely used anymore. And when I try and run this... //this program won't compile public class SomeClass { public static void main(){ System.out.println("This text will never be displayed :("); } } The output shows this in red text: Error: Main method not found in class SomeClass , please define the main method as:

问题 I know that my questions are very simple but googleing them didn't get me any useful results... They'r probably too simple!! No. 1 char* createStr(){ char* str1 = malloc(10 * sizeof(char)); printf("str1 address in memory : %p\n", &str1); return str1; } int main(void){ char* str2 = createStr(); printf("str2 address in memory : %p\n", &str2); } Result: str1 address in memory : 0x7fffed611fc8 str2 address in memory : 0x7fffed611fe8 Why are the addresses different in and out of the createStr()
