module Nuggets::Env::SetMixin - nuggets Application documentation (v1.6.1)

set([env[, clear]]) → aHash click to toggle source

set([env[, clear]]) { ... } → anObject

Overrides ENV with env, clearing it beforehand if clear is true. If a block is given, restores ENV to its original state afterwards and returns the result of the block; otherwise returns the original ENV as a hash.

   # File lib/nuggets/env/set_mixin.rb
38 def set(env = {}, clear = true)
39   old_env = to_hash
40 
41   self.clear if clear
42 
43   env.each { |key, value|
44     key = key.to_s.upcase unless key.is_a?(::String)
45     value = value.to_s unless value.is_a?(::String)
46 
47     self[key] = value
48   }
49 
50   block_given? ? yield : old_env
51 ensure
52   set(old_env) if old_env && block_given?
53 end

Also aliased as: without

with([env[, clear]]) { ... } → anObject click to toggle source

61 def with(env = {}, clear = false)
62   set(env, clear) { yield }
63 end

without(env = {}, clear = true)
