Today I’ll write about new stuff in ruby that I think is nice.
Now the ruby changed the default unicode to utf-8:
puts __ENCODING__
UTF-8
The Ruby 2.0 has a new literal to create array of symbols:
array_of_symbols = %i[one two three]
=> [:one, :two, :three]
Keyword arguments:
def my_args(**keywords)
keywords
end
my_args(name:'edgar')
=> {:name=>"edgar"}
New convention for conversion to hash:
Band = Struct.new(:name, :style)
band = Band.new('Stray Cats', 'Rockabilly')
band.to_h
=> {:name=>"Stray Cats", :style=>"Rockabilly"}These examples was to show you some changes in ruby 2.0.
