我有一个Rakefile以两种方式编译项目,根据全局变量$build_type,它可以是:debug或:release(结果在单独的目录中):
task :build => [:some_other_tasks] do
end
我想创建一个任务,编译项目的两个配置依次,像这样:
task :build_all do
[ :debug, :release ].each do |t|
$build_type = t
# call task :build with all the tasks it depends on (?)
end
end
是否有一种方法可以像调用方法一样调用任务?或者我怎样才能实现类似的目标?
如果您需要将任务作为一个方法来执行,那么使用一个实际的方法如何?
task :build => [:some_other_tasks] do
build
end
task :build_all do
[:debug, :release].each { |t| build t }
end
def build(type = :debug)
# ...
end
如果你更愿意坚持rake的习语,下面是你从过去的答案中编译出来的可能性:
This always executes the task, but it doesn't execute its dependencies:
Rake::Task["build"].execute
This one executes the dependencies, but it only executes the task if
it has not already been invoked:
Rake::Task["build"].invoke
This first resets the task's already_invoked state, allowing the task to
then be executed again, dependencies and all:
Rake::Task["build"].reenable
Rake::Task["build"].invoke
Note that dependencies already invoked are not automatically re-executed unless they are re-enabled. In Rake >= 10.3.2, you can use the following to re-enable those as well:
Rake::Task["build"].all_prerequisite_tasks.each(&:reenable)
