ナナの未来もまだ広がってます。次はどんな色になるか、楽しみです♪

Fixed a bug that prevented build on macOS.

v7.7.11

Fix ‘ruby_nonempty_memcpy’ is not a member of ‘std’ error on Ruby 2.7 and glibc.

I think this is because of a Ruby's ugly bug...

ウサミミ、今夜はちょっとだけお休みです。だって…お姫様、ですから

Add support for pattern matching in Ruby 2.7

json = <<JSON
{
  "maekawa": "miku",
  "osaki": ["tenka", "amana"],
  "hisakawa": {"hayate": "haa", "nagi": "naa"}
}
JSON
data = Usamin.load(json)
#=> {"maekawa"=>"miku", "osaki"=>[...], "hisakawa"=>{...}}

case data
in maekawa:, hisakawa: {**sisters}
    p maekawa
    p sisters
end
# "miku"
# {:hayate=>"haa", :nagi=>"naa"}

Add useful methods

• Hash#invert
• Hash#to_proc

Add :symbolize_names option

• Usamin::parse
• UsaminValue#eval
• UsaminValue#eval_r
• JSON::parse, JSON::load (in overwriting module)

Fix methods' behaviors

• Usamin::Hash#fetch
• Usamin::Hash#merge
• Usamin::Array#[]
• Usamin::Array#fetch
• Usamin::Array#index

Set rapidjson::kParseIterativeFlag as default (for security)

Set :recursive option to disable the flag.
This can cause fatal and unexpected problems.

Usamin.parse('[' * 1000000)
# Usamin::ParserError (Invalid value. Offset: 1000000)

Usamin.parse('[' * 1000000, recursive: true)
# SystemStackError (stack level too deep)

Usamin.parse('[' * 1000000, recursive: true)
# zsh: illegal hardware instruction  bundle console

ウサミン星まで、魔法でワープできたらいいのにな…電車じゃなくて

Implement comparison methods in UsaminValue

Now you can make comparison of UsaminValues and use Hash with UsaminValue keys.

• ==, ===
• eql?, hash

[0, 1, 2] == Usamin.load('[0, 1, 2.0]')
#=> true
[0, 1, 2] == Usamin.load('[0, 1, 2]')
#=> true
[0, 1, 2] == Usamin.load('[1, 2, 3]')
#=> false

hash = {Usamin.load('[0, 1]') => 'hoge'}
hash[Usamin.load('[0, 1]')]
#=> "hoge"

Add some useful methods

• inspect = to_s
• dig
• flatten
• reverse, rotate, rindex (UsaminArray)

Fix bugs

• #2
• behavior of overwritten JSON#load with proc

サンタメイドアイドルです！ちょっと、足し算しすぎですかね？えへへ

Add merge to UsaminHash

Usamin.load('{"a": 3, "b": 4}').merge({'a' => 5, 'c' => 7})
#=> {"a"=>5, "b"=>4, "c"=>7}

Support to_h with a block on Ruby 2.6

json = '[{"name": "miku maekawa", "age": 15}, {"name": "nana abe", "age": 17}]'
Usamin.load(json).to_h{|e| [e['name'], e['age']]}
#=> {"miku maekawa"=>15, "nana abe"=>17}

Support SIMD operations

If available, -march=native, and -msse4.2 or -msse2 options are used on compilation.

Improve memory performance

v7.7.7

Improve memory management

ポンコツウサミン、かわいがってくださいねっ！

Improve stability and GC behaviors

v7.7.5

Fix double free bug

愛するプロデューサーさん！ずっとずっと、ナナを励まして、応援してくださいっ！10 年後も、その先も！

Nana Abe was elected as the 7th Cinderella Girl

The name of "Usamin" is derived from her.

Add some methods to UsaminValue

• Hash methods
  • has_value? = value?
  • key = index
  • rassoc
  • reject
  • slice
  • to_a
  • transform_keys
  • transform_values
  • values_at
• Array methods
  • compact
  • include?

Fix some methods

• Array methods
  • find_index = index

Symbols are also accepted as indexers of Hash

data = Usamin.load('{"a": 3, "b": 5}')
data[:a]
#=> 3

data.key?(:b)
#=> true

Improve Memory Management

あのとき感じた気持ちは、今でもハッキリ覚えています！そうじゃなかったら、ナナはステージに立っていないから。

Add some methods to UsaminValue

• Hash#fetch
• Hash#select
• Array#at
• Array#fetch
• Array#last
• Array#slice

Implement overwriter of default JSON module
