问题 I'm writing a command line tool with Swift and I'm having trouble displaying colors in my shell. I'm using the following code: println("\033[31;32mhey\033[39;39m") or even NSFileHandle.fileHandleWithStandardOutput().writeData("\033[31;32mhey\033[39;39m".dataUsingEncoding(NSASCIIStringEncoding, allowLossyConversion: true)!) It works when I use a simple echo in php (the text is displayed in green) but is there a reason it doesn't work in a Swift command line tool? Thanks! 回答1: Swift has built

问题 I now to ways to detect weather php script runs in cli or web server mode: if (defined('STDIN')) or: if (isset($argc)) Do they equally reliable or one of them is more ? 回答1: Neither. Check the value returned from php_sapi_name() . 回答2: $_SERVER['REQUEST_METHOD'] won't be set, due to the lack of a HTTP request. I think defined( 'STDIN' ) or isset( $argc ) are reliable too, though. If it was up to me, I'd probably go with the defined( 'STDIN' ), as I can imagine someone accidentally setting a

问题 I am trying to run a commandline tool using swift 2 on a mac (10.10): let task = NSTask() task.launchPath = "/path/to/wrong/binary" task.launch() // NSPipe() stuff to catch output task.waitUntilExit() // never reached if (task.terminationStatus != 0){ NSLog("uh oh") } Since the path is wrong, my program dies with launch path not accessible . However, I don't know, how to catch this error. Using do { try } catch {} around task.launch() does not work, because it does not throw an exception,

问题 Is there a way in Laravel 4 to run my controller/action using PHP-CLI? I have a controller/action that I would like to extend to perform an alternative action if the request comes from the CLI, so is there a way to identify the request as a CLI request? The Laravel documentation on this site seems to suggest that there is a method Request::cli() for determining if the current request is via the Artisan CLI but when I used the method in Laravel 4, it throws an error: Call to undefined method

问题 I'm using Windows 10 Home Single Language 64-bit Operating System on my machine. I've installed the latest copy of XAMPP server on my machine which ships with PHP 7.2.7 I read following pages from the PHP Manual : Scan directories .user.ini files After reading the text from these two pages one doubt came to my mind : To scan the configuration INI files on a per-directory basis( in my case '.htaccess files' ) by PHP is it mandatory to run PHP on CLI with the --with-config-file-scan-dir option
