Instance Method Details

#expand(&blk) ⇒ Object

You can use ‘expand` to add more values to the environment after initialization. eg:

# Create the environment:
@env = AppEnv::Environment.new('test/data/env') { |env, src|
  env.var1 = src.var_one
}

# Later, expand it:
@env.expand { |env, src|
  env.var2 = src.var_two
}

# File 'lib/appenv/environment.rb', line 23

def expand(&blk)
  source = _compile_source_env
  blk.call(self, source)
end

#set(property, &blk) ⇒ Object

If you are computing a complex value (say, a conditional one), you might like to set the value via a block. eg:

# Simple variable assignment:
env.var1 = src.var_one

# Variable assignment with `set`:
env.set(:var2) {
  if abcd?
    'xyz'
  else
    'foo'
  end
}
