ruby - 我如何在我的 Rakefile 中声明这种依赖关系？

Question

我正在尝试构建一个静态库，它的名称是在我处理一些文件后才得到的。我有这样的东西:

task :lib,:config do |t,args|
  # ... do some processing here, get a string representing the 
  # fullpath of the lib. Imaging libname contains a.lib
  file libname => object_files
end

但是，当然，因为在任务运行时我不知道依赖项的名称，所以应该构建 a.lib 的代码不会被执行。我试着这样做:

task :lib,:config do |t,args|
  # ... do some processing here, get a string representing the 
  # fullpath of the lib. Imaging libname contains a.lib
  file libname => object_files
  task :lib => [libname]
end

要将其添加为依赖项，但它不起作用。我现在拥有它，并且它有效:

task :lib,:config do |t,args|
  # ... do some processing here, get a string representing the 
  # fullpath of the lib. Imaging libname contains a.lib
  file libname => object_files
  Rake.application[libname].invoke
end

但是我觉得太丑了。有没有更好的方法来声明这种依赖关系？
