可以调用可执行的Thor驱动的脚本而不调用thor？ [英] Possible to call executable Thor-powered script without calling thor?

问题描述

我有一个基于thor的Ruby脚本，但我想将它作为一个gem部署在人们的 bin 目录中，人们可以不必做<$ c $所以他们只是使用 mytool

p>

这是否可能？

我知道可以使用vanilla optparse

更新：这是我使用的代码基于上面的例子。 Thor页面，但我得到以下错误：

 ＃！/ usr / bin / env thor 
 $ b b class App< Thor 
 map-L=> ：list 
 
 desc安装APP_NAME，安装一个可用的应用程序
 method_options：force => ：boolean，：alias => ：string 
 def install（name）
 user_alias = options [：alias] 
 if options.force？ 
＃do something 
 end 
＃其他代码
 end 
 
 desclist [SEARCH]，列出所有可用的应用程式，限制SEARCH
 def list（search =）
＃list everything 
 end 
 end 
  

错误：

解决方案

创建shebang行

 ＃！/ usr / bin / env ruby​​ 
  

，然后在脚本的末尾添加

  App.start 
  

I have a thor-based Ruby script, but I want to deploy it as a gem in people's bin directories that people can hit without having to do thor mytool.

So instead they'd just use mytool

Is this possible?

I know it's possible with vanilla optparse but I'd rather use Thor if possible.

Update: This is the code I'm using based on the example on the Thor page, but I get the error below:

#!/usr/bin/env thor

class App < Thor
  map "-L" => :list

  desc "install APP_NAME", "install one of the available apps"
  method_options :force => :boolean, :alias => :string
  def install(name)
    user_alias = options[:alias]
    if options.force?
      # do something
    end 
    # other code
  end 

  desc "list [SEARCH]", "list all of the available apps, limited by SEARCH"
  def list(search="")
    # list everything
  end 
end

Error:

解决方案

Make the shebang line

#!/usr/bin/env ruby

and then at the end of your script add

App.start
