command-line-interface

问题 I have a class that gets initialized with a previously unknown number of arguments and I want it to be done on cli using python click package. My issue is that I can't manage to initialize it and run a click command: $ python mycode.py arg1 arg2 ... argN click_command because with variadic arguments option nargs=-1 click don't recognize the click_command as a command. How can I input N args and then run a command using click? Setting a defined number of arguments, like nargs=5 , solves the

问题 I wanted to create a commandline-like / shell-like interface in python3. Argparse seems to do the job of parsing and displaying the help/error messages. According to the python3 documentation of argparse, there is a func= argument that can be used to get your function called by argparse . # sub-command functions def foo(args): print(args.x * args.y) def bar(args): print('((%s))' % args.z) # create the top-level parser parser = argparse.ArgumentParser() subparsers = parser.add_subparsers() #

问题 I am creating an app with Click in python 3.6. I seem to have an error that I cannot find. I have posted my code below. The problem is that when I type: python clickapp.py --help all is good. But when I type python clickapp.py simplerequest --help I get an error indicating that I am missing the argument "directory", but there is no traceback to indicate the source of the error. The exact output is: Usage: clickapp.py [OPTIONS] STARTDATE ENDDATE DIRECTORY COMMAND [ARGS]... Error: Missing

问题 I dont know how to properly term what i want. I want to make a program that doesnt just print and scroll but still be a linux-CLI program. Lets say i write a program that does 3 things: 1, its tails a logfile 2, it shows the time 3, it runs a continous ping. And say i want the time to be displayed in lower right corner, i want the logtail to scroll in the upper 5 lines of the terminal, and i want the ping to scroll (separately) in the main body of the terminal. So what i am asking, basicly,

问题 How do I convert a fixed byte array to a String in managed c++/cli ? For example I have the following Byte array. Byte byte_data[5]; byte_data[0]='a'; byte_data[1]='b'; byte_data[2]='c'; byte_data[3]='d'; byte_data[4]='e'; I have tried the following code String ^mytext=System::Text::UTF8Encoding::UTF8->GetString(byte_data); I get the following error: error C2664: 'System::String ^System::Text::Encoding::GetString(cli::array<Type,dimension> ^)' : cannot convert parameter 1 from 'unsigned char

问题 Final Update. Problem Solved. The way I solve the problem is re-install Apache and PHP entirely from source following the instruction by the following link. http://dan.drydog.com/apache2php.html Then do the extension by build the extension directly into PHP following the instruction by the link down below. The only thing is that the binaries are all only in the specific path, which I think is a easy problem to solve though. Thanks everyone, this is my first post in Stackoverflow and I spend

问题 I have a command line utility which opens a serial connection specified by args sent in (duh) the command line. After the utility starts, I can type into the std input to send strings to the port to which I am connected. What I would like to do is start the utility with a batch file (easy enough), then automate the keystrokes I wish to send. I am having no luck on my own and need some expert advice. I'll give a more specific example: I start teraterm.exe (opensource serial communication

问题 does anyone know the steps required to debug the agi secript (a2billing.php) of asterisk . I am able to remote debug php cli if i call it form the linux console. but if it runs from within asterisk , it does not work. any idea how to debug it ? 回答1: To turn debug mode of a2billing you have to go config, and in agi-confX put verbose ->DEBUG(see comments) After that you can check a2billign debug file(specified in /etc/a2billng.conf) or do from console asterisk -r agi set debug on core set

问题 This is a similar question to this SO post, which I have been unable to use to solve my problem. I have included some code here, which will hopefully help someone to bring home the message that the other posting was getting at. I want to write a CLI/C++ method that can take a void pointer as a parameter and return the managed object (whose type I know) that it points to. I have a managed struct: public ref struct ManagedStruct { double a; double b;}; The method I am trying to write, which
