難解設定記述言語Watson

Posted at

この記事は、 ミクシィグループ Advent Calendar 2020 の 19日目 の記事です。

難解プログラミング言語があるのなら、あえてチューリング完全でなくした難解設定記述言語があってもいいんじゃないかということで作ってみました。

リポジトリはこちら: genkami/watson

基本的な使い方

Watsonは内部にチューリング完全でないスタックマシンを持っており、Watsonファイルのすべての文字はスタックマシンへの命令へとみなされます。

完全な命令の一覧は 仕様書 を参照してください。

数値

数値に関する基本的な命令は、以下のようなものがあります:

  • スタックに数値 0 を積む命令 B
  • スタックの先頭にある値をインクリメントする命令 u
  • スタックの先頭にある値を左に1ビットシフトする命令 b
  • スタックの先頭2つの値を足す命令 a

これらを組み合わせて、任意の数値を表すことができます:

$ echo 'BBuaBubaBubbbaBubbbbaBubbbbbaBubbbbbba' | watson decode -t json
123

文字列

文字列(バイト列)に関する命令は以下の2つがあります:

  • スタックに空文字列を積む命令 ?
  • スタックの先頭にある数値の下位1バイトを、スタックの先頭から2番目にある文字列の末尾に追加する命令 !

ただし、スタックに空文字列を積むと命令テーブルが変わります。先程説明した命令 B, u, b, a, ?, ! は、それぞれ S, h, a, k, $, - に変化します。もう一度空文字列をスタックに積むともとに戻ります。

echo '
?SShaaarrkShaaaaarrkShaaaaaarrk-SShkSharrkShaarrkShaaarrkShaaaaarrkShaaaaaarrk-SShkSharrkShaarrkShaaaaarrkShaaaaaarrk-SShkShaarrkShaaaaarrkShaaaaaarrk-
' | watson decode -t json
"hoge"

真偽値

true または false をとる値です。真偽値に関する命令は以下の2つがあります:

  • false をスタックに積む命令 z
  • スタックの先頭にある真偽値の値を反転させる命令 o

ただし、これらは一旦空文字列がスタックに積まれるとそれぞれ ^, ! に変化します。

$ echo 'zo' | watson decode -t json
true

オブジェクト

いわゆる連想配列です。オブジェクトに関する命令は以下の2つがあります:

  • 空オブジェクトをスタックに積む命令 ~
  • スタックの先頭から3番目にあるオブジェクトに、スタックの先頭から2番目にある値をキー、スタックの先頭にある値を値として追加する命令 M

ただし、これらは一旦空文字列がスタックに積まれるとそれぞれ +, g に変化します。

$ echo '
~?ShaaaaaaShaaaaakShaaak-
ShaaaaaaShaaaaakShaakShk-
ShaaaaaaShaaaaakShaaakShaak-
ShaaaaaaShaaaaakShaaakShaak-
ShaaaaaaShaaaaakShaaakShaakShakShk-$

ShaaaaaaShaaaaakShaaaakShakShk-
ShaaaaaaShaaaaakShaaaakShaak-
^!g
' | watson decode -t json
{"first":true,"hello":"world"}

発展的な使い方

KubernetesでNginxをデプロイする

watson コマンドはWatsonをYAMLに変換できるので、これまでに説明した命令を組み合わせることで簡単にKubernetesマニフェストを書くことができます。

関数

Watsonには関数という概念はありませんが、Watsonファイルはスタックマシンへの命令列であるため、擬似的に関数のようなものを再現することができます。
例えば、次のような引数をスタックに積むファイル args.watson と関数呼び出しに相当する function.watson を用意して、

$ cat examples/function/args.watson
?

watson コマンドに順番に処理させることで、次のようなことができます:

$ watson decode -t yaml examples/function/args.watson examples/function/function.watson
anotherValue: this value is loaded from function.watson
value: this value is loaded from args.watson

この機能をうまく活用することで、今までHelmやKustomizeで管理していたKubernetesマニフェスト類をより複雑に管理することができるようになるかもしれません！

Goライブラリ

Watsonにはコマンドラインツールだけでなく、Go用のライブラリも用意されています。
使い方は encoding/json などとほぼ同様です。

package main

import (
    "fmt"

    "github.com/genkami/watson"
)

type Person struct {
    FullName string `watson:"fullName"`
    Nickname string `watson:"nickname,omitempty"`
}

func main() {
    user := Person{
        FullName: "Yamada Taro",
    }
    buf, err := watson.Marshal(&user)
    if err != nil {
        panic(err)
    }
    fmt.Printf("%s\n", buf)
}

$ go run main.go

他のフォーマットとの相互変換

watson コマンドはWatsonとJSON, YAML, MessagePack, CBORとの相互変換を行うことができます。

$ echo 'a: 1' | watson encode -t yaml
~?SShkShaaaaarrkShaaaaaarrk-SShkg

$ echo '~?SShkShaaaaarrkShaaaaaarrk-SShkg' | watson decode -t yaml
a: 1

これを利用して、例えば　watson コマンドを使ってJSONをMessagePackに変換することもできます:

$ echo '{"hoge": "fuga"}' | watson encode -t json | watson decode -t msgpack |
