制作红宝石响应终端命令 [英] Making ruby gems respond to terminal commands

问题描述

我对红宝石以及宝石制作极其新颖。我做了一个简单的宝石，根据输入信息对一些信息进行网络扫描。
然而，要使用我的宝石，我需要进入解释器（irb）并需要我的宝石，然后用一些参数调用该方法。

假设宝石被称为 foo 。
假设这个方法叫做 print_website（x）＃其中x是一个字符串。

我想能够做这样的事情：

  $ foo test.com 
  

，它应该自动调用该方法并执行它。

预先感谢！如果我不清楚，请问我澄清！ ：D

解决方案

试试看

  $ mkdir bin 
 $ touch bin / foo 
 $ chmod a + x bin / foo 
  

编辑 bin / foo

 ＃！/ usr / bin / env ruby 
 
需要'foo'
＃你想要的东西....... 
  

将以下内容添加到Gemfile中

  s可执行文件<< 'foo'
  

推宝石。现在你发布了命令行工具

I am extremely new to ruby as well as gem making. I made a simple gem that webscrapes some information depending on the input. However, to use my gem I need to go into the interpreter (irb) and require my gem and then call the method with some parameters.

Suppose the gem is called foo. Suppose the method is called print_website(x) # where x is a string.

I want to be able to do something like:

$ foo test.com

and it should automatically call the method and execute it.

Thanks in advance! Please ask me for clarification if i was unclear! :D

解决方案

Try it

$ mkdir bin
$ touch bin/foo
$ chmod a+x bin/foo

Edit bin/foo

#!/usr/bin/env ruby

require 'foo'
#Anything you want.......

Add following to Gemfile

 s.executables << 'foo'

Push gem. Now you published command line utility
