Allow Hash#smash to include the options

[Jakanapes]

it would be nice to be able to call hash.smash(smash_array: true) instead of having to do Flatten.smash(hash, smash_array: true)

Thank you for your interest in flatten! I hope you find it useful.

Here're my thoughts on this PR:

The readme suggests calling flatten this way:

my_house.smash
{
    "dh-description" => "my house in dunwoody",
         "dh-street" => "5252 vernon lake drive",
           "dh-city" => "atlanta",
          "dh-state" => "GA",
              "name" => "lex"
}

If we were to merge your changes, it seems we'd by saying the following is preferable:

my_house.smash(smash_array: true)
{
    "dh-description" => "my house in dunwoody",
         "dh-street" => "5252 vernon lake drive",
           "dh-city" => "atlanta",
          "dh-state" => "GA",
              "name" => "lex"
}

Isn't the first way simpler? What's the benefit of providing a longer way to do the same thing?

Best, Lex

But it's not the same thing. I'd like to be able to specify that it smash arrays and add a separator.

h = { "build" => { "year" => 1925, "color" => "red" }, "images" => ["url1", "url2"] }

[7] pry(main)> h.smash
=> {"year"=>1925, "color"=>"red", "images"=>["url1", "url2"]}

[8] pry(main)> h.smash(smash_array: true, separator: '/')
=> {"build/year"=>1925, "build/color"=>"red", "images/0"=>"url1", "images/1"=>"url2"}

Basically, I want the same output as this

[9] pry(main)> Flatten.smash(h, smash_array: true, separator: '/')
=> {"build/year"=>1925, "build/color"=>"red", "images/0"=>"url1", "images/1"=>"url2"}

It's not terrible to call the class method, but it would be convenient to be able to call it from an instantiated hash object.
