问题 I have a problem I am trying to find a solution. I am not sure if I can do it with argparse. I want to be able to specify an option myprog -a 1 myprog -a 2 Now when I have a = 1 , I want to be able to specify b and c . But when a = 2 , I can only specify d . myprog -a 1 -b 3 -c 0 myprog -a 2 -d 3 Also a must always be specified 回答1: You can't do this with switched values as a single parse_args call, but you can do one of: Use sub-commands/sub-parsers Do partial parsing before fully

问题 I just wrote a script to release a build of one of the products I'm working on. The script does the job, but I don't really like the code itself, looks like spaghetti code and callback hell combined. Is there a cleaner way to do this? I'd like to be able to run commands in series, log the outputs ( stdout.on('data') ) and when the task is finished. (easier for further debug and when waiting for the task to be done, reassuring to know what's happening on the background) Maybe using Promises

问题 I have a maintenance script for a Wordpress install that I run through the command line, after initializing my wp enviroment thus: define( 'WP_USE_THEMES', FALSE ); $_SERVER = [ "HTTP_HOST" => "example.com", "SERVER_NAME" => "example.com", "REQUEST_URI" => "/", "REQUEST_METHOD" => "GET" ]; require( 'wordpress/wp-load.php' ); Later down the road I'll send e-mail notifications using wp_mail. The thing is, I'm using a plugin that would normally override the default wp_mail for its own, since it

问题 How would I respond to a command line prompt programmatically with node.js? For example, if I do process.stdin.write('sudo ls'); The command line will prompt for a password. Is there an event for 'prompt?' Also, how do I know when something like process.stdin.write('npm install') is complete? I'd like to use this to make file edits (needed to stage my app), deploy to my server, and reverse those file edits (needed for eventually deploying to production). Any help would rock! 回答1: You'll want

问题 According to the documentation of the extra property of the composer.json schema, allows setting of "arbitrary extra data for consumption by scripts." For scripting purposes, it would be nice if data can be added to the extra property via the command-line. It have tried composer config extra.foo bar , but this gives the error Setting extra.foo does not exist or is not supported by this command . So I was wondering: is there a way to use the Composer CLI to add data to the extra property?

问题 I often come across a string representing UTF-16BE, such as \u0444\u0430\u0439\u043b , which would be properly rendered as файл . I wonder: is there a simple way to "render" a text file in UTF-16BE (or simply an input string in in UTF-16BE) such as the one above by using sed or other command line tool? See also this related question. 回答1: Assuming the text is actually encoded in UTF-16BE (and not, as you show in your question, as an ASCII string containing backslash and 'u' characters), you

问题 I am fairly new to NodeJS development. I have no issues whatsoever running commands on my local machine. For instance, say I want to install a package called "formidable" on my Node server, I'd run the command 'npm install formidable'. If I have deployed my NodeJS application to Azure, how would I run the same command? NB - I do not want to manually run the command on my local machine and then deploy to Azure. This will take far too long, since I have to install many packages each with many
