是否可以从Thor脚本中调用Git或其他命令行工具？ [英] Is it possible to call Git or other command line tools from inside a Thor script?

问题描述

我发现在我为Rails 3应用程序进行git commit之前和之后，我经常运行一系列例行的清理任务。

我是考虑将这些东西放到Thor脚本中，但是我还没有弄清楚的是如何使用Thor（或Rake）来调用系统上的其他工具。

是否可以从Thor或Rake脚本中调用像 git log 这样的命令，如果是这样的话，它看起来像什么？

谢谢！

解决方案

  result =％x（git log）
 puts结果
  

或

 系统（'git log'）
  

如果您只是想将输出传递给终端。

还有 grit gem将Git工具抽象为Ruby库：

 需要'gri t'
 repo = Grit :: Repo.new（/ path / to / repo）
 repo.commits.each do | commit | 
 puts＃{commit.id}：＃{commit.message}
 end 
  

I find that I'm often running a sequence of routine 'cleanup' tasks before and after I make a git commit for my Rails 3 app.

I was thinking about putting these things into a Thor script, but one thing I haven't been able to figure out is how to use Thor (or Rake) to call other tools on the system.

Is it possible to call a command like git log from a Thor or Rake script, and if so what does that look like?

Thanks!

解决方案

Just shell out:

result = %x(git log)
puts result

or

system('git log')

if you just want to pass the output to the terminal.

There is also the grit gem that abstracts the Git tools into a Ruby library:

require 'grit'
repo = Grit::Repo.new("/path/to/repo")
repo.commits.each do |commit|
  puts "#{commit.id}: #{commit.message}"
end
