Class Method Details

.presence(translation) ⇒ String^?

Note:

Unlike ActiveSupport’s Object#presence this method doesn’t treat a string made of spaces as blank

"  ".presence #=> nil
Mova.presence("  ") #=> "  "

Examples:

Mova.presence("hello") #=> "hello"
Mova.presence(nil) #=> nil
Mova.presence("") #=> nil

Returns:

• (String) —

  if translation is non-empty string

• (nil) —

  if translation is nil or an empty string

Since:

• 0.1.0

# File 'lib/mova.rb', line 22

def self.presence(translation)
  return nil if translation == EMPTY_TRANSLATION
  translation
