ruby - 平台系列与 rubocop 的阵列

Question

我正在尝试在 Chef 中为 platform_family 使用一个数组，根据 Chef 文档，我有正确的语法，但 rubocop 正在踢我的屁股。

Chef 文档:https://docs.chef.io/dsl_recipe.html#value-for-platform-family

对 ruby 新手有什么想法吗？

 12 tcp_ports = value_for_platform_family(
 13   ['debian', 'rhel'] => [22, 443, 4172, 60443],
 14   'windows' => [443, 3389, 4172, 60443]
 15 )

rubocop 错误是

recipes/recipe.rb:13:3: C: Style/WordArray: Use %w or %W for an array of words.
  ['debian', 'rhel'] => [22, 443, 4172, 60443],
  ^^^^^^^^^^^^^^^^^^

Answer 1

在处理集合时，Rubocop 添加:

Prefer %w to the literal array syntax when you need an array of words (non-empty strings without spaces and special characters in them). Apply this rule only to arrays with two or more elements.

# bad
STATES = ['draft', 'open', 'closed']

# good
STATES = %w[draft open closed]

请注意，从 Ruby 风格指南的角度来看这很糟糕，但代码仍然有效。

所以你的例子是:

%w[debian rhel]
