[ruby-dev:52083] I RECORDED YOU!

Hello there! Unfortunately, there are some bad news for you. Some time ago your device was infected with my private trojan, R.A.T (Remote Administration Tool), if you want to find out more about it simply use Google. My trojan allowed me to access your files, accounts and your camera. Check the sender of this email, I have sent it from your email account. To make sure you read this email, you will receive it multiple times. You truly enjoy checking out porn websites and watching dirty videos, while having a lot of kinky fun. I RECORDED YOU (through your camera) SATISFYING YOURSELF! After that I removed my malware to not leave any traces. If you still doubt my serious intentions, it only takes couple mouse clicks to share the video of you with your friends, relatives, all email contacts, on social networks, the darknet and to publish all your files. All you need is $1800 USD in Bitcoin (BTC) transfer to my account. After the transaction is successful, I will proceed to delete everything. Be sure, I keep my promises. You can easily buy Bitcoin (BTC) here: https://cex.io/buy-bitcoins https://nexo.com/buy-crypto/bitcoin-btc https://bitpay.com/buy-bitcoin/?crypto=BTC https://paybis.com/ https://invity.io/buy-crypto Or simply google other exchanger. After that send the Bitcoin (BTC) directly to my wallet, or install the free software: Atomicwallet, or: Exodus wallet, then receive and send to mine. My Bitcoin (BTC) address is: 13HAreeSVjLf3aueZXf9zmrS1FmvkF4opS Yes, that's how the address looks like, copy and paste my address, it's (cAsE-sEnSEtiVE). You are given not more than 3 days after you have opened this email. As I got access to this email account, I will know if this email has already been read. Everything will be carried out based on fairness. An advice from me, regularly change all your passwords to your accounts and update your device with newest security patches.

[ruby-dev:52158] [Ruby Feature#14916] Proposal to add Array#===
by matheusrich (Matheus Richard) 16 May '25

Issue #14916 has been updated by matheusrich (Matheus Richard). This is probably unnecessary now that pattern matching exists. ---------------------------------------- Feature #14916: Proposal to add Array#=== https://bugs.ruby-lang.org/issues/14916#change-113306 * Author: osyo (manga osyo) * Status: Open ---------------------------------------- ## 概要 `Array#===` を追加する提案になります。基本的な動作は『`Array#==` の `===` で比較する版』になります。 ## 仕様配列の各要素をそれぞれ順に `===` で比較し、全要素が `true` の場合に `true` を返す。そうでない場合は `false` を返す。 ### 動作例 ```ruby # 配列の各要素を #=== を使用して比較する [ String, /\w/ ] === [ "a", "c", 7 ] # => false [ String, /\w/, (1..10) ] === [ "a", "c", 7 ] # => true [ String, /\w/, (1..10) ] === [ "a", "!", 42 ] # => false ``` ### 真を返すケース * レシーバと引数が配列で同じサイズかつ、各要素を `===` で比較したときに全て `true` になる場合 * レシーバと引数が同じオブジェクトの場合 ### 偽を返すケース * レシーバと引数が配列で同じサイズかつ、各要素を `===` で比較したときに `false` がある場合 * レシーバと引数の配列のサイズが異なる場合 * 引数が配列以外の場合 ## ユースケース ### 引数の値によって処理を変える可変長引数で引数を受け取り、そのまま case-when で値を精査する ```ruby def plus *args case args # 数値の場合 when [Integer, Integer] args[0] + args[1] # 数字の場合 when [/^\d+$/, /^\d+$/] args[0].to_i + args[1].to_i # それ以外はエラー else raise "Error" end end p plus 1, 2 # => 3 p plus "3", "4" # => 7 p plus "homu", "mado" # Error (RuntimeError) ``` ### FizzBuzz を用いた例任意の処理の結果を複数回参照したい場合、配列でまとめて case-when で利用する ```ruby def fizzbuzz n _ = proc { true } case [n % 3, n % 5] # n % 3 === 0 && n % 5 === 0 when [0, 0] "FizzBuzz" # n % 3 === 0 when [0, _] "Fizz" # n % 5 === 0 when [_, 0] "Buzz" else n end end p (1..20).map &method(:fizzbuzz) # => [1, 2, "Fizz", 4, "Buzz", "Fizz", 7, 8, "Fizz", "Buzz", 11, "Fizz", 13, 14, "FizzBuzz", 16, 17, "Fizz", 19, "Buzz"] ``` ## 関連しそうなチケット * [Feature #14869: Proposal to add Hash#=== - Ruby trunk - Ruby Issue Tracking System](https://bugs.ruby-lang.org/issues/14869?next_issue_id=14866&prev_is… * [Feature #14913: Extend case to match several values at once - Ruby trunk - Ruby Issue Tracking System](https://bugs.ruby-lang.org/issues/14913) 以上、 `Array#===` に関する提案になります。挙動に関して疑問点や意見などございましたらコメント頂けると助かります。 ---Files-------------------------------- array_eqq.patch (3.06 KB) array_eqq.patch (3.2 KB) array_eqq.patch (3.41 KB) -- https://bugs.ruby-lang.org/
