在我的Guardfile中,我有这种奇怪的方法调用语法rspec.spec.("requests/#{m[1]}")
。虽然这很有效但我不明白实际调用的是什么方法。
此语法是否有名称或术语?
guard :rspec, cmd: "bundle exec rspec" do
# ...
watch(rails.controllers) do |m|
[
rspec.spec.("routing/#{m[1]}_routing"),
rspec.spec.("controllers/#{m[1]}_controller"),
rspec.spec.("requests/#{m[1]}")
]
end
end

尝试:
foo = "Foo"
foo.("a")
# NoMethodError: undefined method `call' for "Foo":String
routine = Proc.new { |arg| puts "Hello #{arg}!" }
routine.("world")
# Hello world!
