运行不带参数或任务名称的 CLI Thor 应用程序

发布于 2024-12-02 09:01:03 字数 298 浏览 2 评论 0原文

我正在寻找一种方法来创建一个命令行雷神应用程序，该应用程序将运行不带任何参数的默认方法。我摆弄了 Thor 的 default_method 选项，但仍然要求我传递一个参数。我发现了一个类似案例，有人想要运行带参数但不带任务名称的 CLI Thor 任务。

我想运行一个没有任务名称和参数的任务。这样的事可能吗？

似乎执行此操作的正确雷神方法是使用 default_task：

class Commands < Thor
  desc "whatever", "The default task to run when no command is given"
  def whatever
    ...
  end
  default_task :whatever
end
Commands.start

如果出于某种原因这不是您所需要的，您应该能够执行类似的操作

class Commands < Thor
  ...
end

if ARGV.empty?
  # Perform the default, it doesn't have to be a Thor task
  Commands.new.whatever
else
  # Start Thor as usual
  Commands.start
end

It seems the proper Thor-way to do this is using default_task:

class Commands < Thor
  desc "whatever", "The default task to run when no command is given"
  def whatever
    ...
  end
  default_task :whatever
end
Commands.start

If for whatever reason that isn't what you need, you should be able to do something like

class Commands < Thor
  ...
end

if ARGV.empty?
  # Perform the default, it doesn't have to be a Thor task
  Commands.new.whatever
else
  # Start Thor as usual
  Commands.start
end

有点黑客，但无论如何只有一个定义的操作，我只是将操作名称添加到传入的 ARGV 数组中：

class GitTranslate < Thor
  desc "translate <repo-name>", "Obtain a full url given only a repo name"
  option :bitbucket, type: :boolean, aliases: 'b' 
  def translate(repo)
    if options[:bitbucket]
      str = "freedomben/#{repo}.git"
      puts "SSH:   [email protected]:#{str}"
      puts "HTTPS: https://[email protected]/#{str}"
    else
      str = "FreedomBen/#{repo}.git"
      puts "SSH:   [email protected]:#{str}"
      puts "HTTPS: https://github.com/#{str}"
    end 
  end 
end

然后我通过传入 ARGV 来启动该类：

GitTranslate.start(ARGV.dup.unshift("translate"))

Kind of hackish, but where there's only one defined action anyway, I just prepended the action name to the ARGV array that gets passed in:

class GitTranslate < Thor
  desc "translate <repo-name>", "Obtain a full url given only a repo name"
  option :bitbucket, type: :boolean, aliases: 'b' 
  def translate(repo)
    if options[:bitbucket]
      str = "freedomben/#{repo}.git"
      puts "SSH:   [email protected]:#{str}"
      puts "HTTPS: https://[email protected]/#{str}"
    else
      str = "FreedomBen/#{repo}.git"
      puts "SSH:   [email protected]:#{str}"
      puts "HTTPS: https://github.com/#{str}"
    end 
  end 
end

Then where I start the class by passing in ARGV:

GitTranslate.start(ARGV.dup.unshift("translate"))

虽然它有点hackish，但我通过捕获选项作为参数本身解决了类似的问题：

argument :name

def init
 if name === '--init'
   file_name = ".blam"
   template('templates/blam.tt', file_name) unless File.exists?(file_name)
   exit(0)
 end
end

当在 Thor::Group 中运行时，此方法在其他方法之前执行，让我欺骗程序做出响应到像论证这样的选项。

此代码来自 https://github.com/neverstopbuilding/blam。

While it is a little hackish, I solved a similar problem by catching the option as the argument itself:

argument :name

def init
 if name === '--init'
   file_name = ".blam"
   template('templates/blam.tt', file_name) unless File.exists?(file_name)
   exit(0)
 end
end

When running in a Thor::Group this method is executed before others and lets me trick the program into responding to an option like argument.

This code is from https://github.com/neverstopbuilding/blam.
