rejoin(input, opts \\ []) View Source 
rejoin(input :: String.t(), opts :: Keyword.t()) :: String.t()

Splits the input and rejoins it with a separator given. Optionally converts parts to downcase, upcase or titlecase.

  • opts[:case] :: [:down | :up | :title | :none]
  • opts[:separator] :: binary() | integer()

Default separator is ?_, default conversion is :downcase so that it behaves the same way as to_snake/1.

Examples 

iex> Case2.rejoin "foo_barBaz-λambdaΛambda-привет-Мир", separator: "__"
"foo__bar__baz__λambda__λambda__привет__мир"
