问题 I was asked to simulate CLI with Python. This is what I did def somefunction(a,b): //codes here //consider some other functions too print "--- StackOverFlow Shell ---" while True: user_input = raw_input("#> ") splitit = user_input.split(" ") if splitit[0] == "add": firstNum = splitit[1] sNum = splitit[2] result = somefunction(firstNum, sNum) print result //consider some other elif blocks with "sub", "div", etc else: print "Invalid Command" I do also check the length of the list, here "splitit

问题 Using Groovy CliBuilder, ideally I would like to have an cmd-line as follows: ./MyProgram.groovy CommandName -arg1 -arg2 -arg3 Is is possible to parse pull out the CommandName as an argument using CliBuilder? 回答1: You can do that if you set the property stopAtNonOption to false so that the parsing does not stop in CommandName . Then you can get the command from CliBuilder options. A tiny example below: def test(args) { def cli = new CliBuilder(usage: 'testOptions.groovy [command] -r -u',

问题 I've been using a few Yeoman Generators that prompt me for user input. I'd prefer to put my inputs in a JSON file though. I can see that yo-rc.json gets generated afterwards, but I'd like to use that (or a file like it) as an input to Yeoman. Example using JHipster: Current Behavior $ yo jhipster Welcome to the JHipster Generator v2.16.1 ? (1/15) What is the base name of your application? (jhipster) helpme ? (2/15) What is your default Java package name? com.mycompany.helpme ... # Yeoman

问题 I'm writing a simple diary console program. Can't really figure out what the easiest way to break up text input from the user. I take in a diary note in a string and then I want to be able to print that string to the console, but unformatted it of course just shows the string in one long line across the terminal making it terribly unfriendly to read. How would I show the string with a new line for every x characters or so? All I can find about text formatting is System.out.printf() but that

问题 I'm developing a CLI in node that will be published to NPM. Since it's a CLI application, I want it to be included in the path once it's installed, so it's not require to type "node my-app.js" to run it. I want it to run with only "my-app". In the package.json, I'm including: "bin": { "my-all" : "./my-app.js" }, But this makes fail the installation via NPM with this error Error: ENOENT, chmod '/home/user1/node_modules/my-app/my-app' 回答1: Assuming you're on some kind of unix (linux, osx), put

问题 I am writing an application that has both CLI and GUI. I read most questions and articles regarding it, and found highly usefull this question: Can one executable be both a console and GUI application? My final code looks like: if (args.Length > 0) { //console code } else { FreeConsole(); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form()); } This works great when running the .exe by double click, or when debugging, or from

问题 I'm using Console_Getopt in PHP 5.2, and finding it surprising about how different it is from getopt in other languages (perl, bash, java). Can anyone recommend how to parse the args from the array "$opts" returned? php myprog.php -a varA -c -b varB $o= new Console_Getopt; $opts = $o->getopt($argv, "a:b:c"); print_r($opts); // the print_r returns below Array ( [0] => Array ( [0] => Array ( [0] => a [1] => varA ) [1] => Array ( [0] => c [1] => ) [2] => Array ( [0] => b [1] => varB ) ) [1] =>
