Buat juru bahasa untuk ya!

Ya adalah bahasa berbasis tumpukan yang memiliki beberapa petunjuk yang dipisahkan oleh ruang:

yes: Push 1 to the stack
no: Push 0 to the stack
what: Push the input to the stack (input is taken at the start of program execution and is the same for the whole execution)
sure: Increment the last item in the stack
nah: Decrement the last item in the stack
really: If the last stack item is a number, replace it with its Unicode character. If it is a letter, replace it with its Unicode char code.
oh: convert the stack to strings and concatenate it, and push that to the stack.
nope: remove the first stack item
yep: remove the last stack item

Elemen terakhir stack selalu dihasilkan pada akhir program. Semua karakter non-alfanumerik dan non-spasi diabaikan. Semua kode adalah huruf kecil. Contoh program:

Anda harus menulis penerjemah sesedikit mungkin. Berikut ini adalah implementasi JS (tidak golf dengan baik!):

function yes(code, input){
	var stack = [];
	var functions = {
		"yes": "stack.push(1)",
		"no": "stack.push(0)",
		"what": "stack.push(input)",
		"sure": "stack[stack.length - 1] ++",
		"nah": "stack[stack.length - 1] --",
		"really": "stack[stack.length - 1] = (typeof lastItem === 'number' ? String.fromCharCode(lastItem) : lastItem.charCodeAt())",
		"oh": "stack.push(stack.reduce((x, y)=>''+x+y))",
		"nope": "stack.shift()",
		"yep": "stack.pop()"
	};
	code.replace(/[^a-z ]/g, "").split(" ").map(x=>(lastItem = stack[stack.length - 1],eval(functions[x])));
	return stack[stack.length - 1];
}
textarea{

Anda dapat mengasumsikan bahwa semua bilangan bulat yang terlibat akan kurang dari atau sama dengan 126, yang reallytidak akan pernah dijalankan dengan string multi-char di atas tumpukan, dan bahwa tumpukan tidak akan pernah lebih dari 100 elemen.

Kasus tepi

  • yes yes ohcetakan 11.
  • Intput dapat berupa string atau angka.
  • Kode dapat berisi karakter apa saja. Yang tidak cocok [a-z ]harus diabaikan.

Emigna
@Emigna Tidak ada kasus uji tentang ini, tidak ada spesifikasi, dan OP belum mengklarifikasi ini bahkan setelah seseorang meninggalkan komentar.
Okx
Saya perhatikan kurangnya kasus-uji. Tidak melihat apa pun di komentar tentang ini, jadi saya bertanya-tanya karena program rujukannya mengabaikan perintah yang tidak valid sementara Anda mungkin menjalankannya sebagai perintah yang valid jika jumlah kode karakter cocok dengan perintah yang valid.

JavaScript (ES6), 218 215 204 203 byte

Mengambil string program sdan input idalam sintaks currying (s)(i).

s=>i=>s.replace(/\w+/g,S=>(c=eval("[P()];P()+1;[s.shift()];1;0;s=[s.join``];P()-1;i;P()[0]?k.charCodeAt():String.fromCharCode(k)".split`;`[parseInt(S,35)%156%9])).map||s.push(c),s=[],P=_=>k=s.pop())&&P()

Bagaimana?

Kami menggunakan fungsi hash sempurna parseInt(S, 35) % 156 % 9untuk mengubah instruksi S menjadi indeks dalam 0… 8 dan menggunakan indeks ini untuk memilih kode JS yang akan dieksekusi:

instruction | base 35 -> dec. | % 156 | % 9 | JS code
------------+-----------------+-------+-----+---------------------------------------------
"yes"       |           42168 |    48 |   3 | 1
"no"        |             829 |    49 |   4 | 0
"what"      |         1393204 |   124 |   7 | i
"sure"      |         1238209 |    37 |   1 | P()+1
"nah"       |           28542 |   150 |   6 | P()-1
"really"    |      1439554619 |    35 |   8 | P()[0]?k.charCodeAt():String.fromCharCode(k)
"oh"        |             857 |    77 |   5 | s=[s.join``]
"nope"      |         1016414 |    74 |   2 | [s.shift()]
"yep"       |           42165 |    45 |   0 | [P()]

The P Fungsi muncul item terakhir dari tumpukan s dan beban ke k .

Kami mencegah hasil beberapa instruksi agar tidak didorong kembali ke stack dengan menguji apakah metode .map () didefinisikan, yaitu, jika hasilnya adalah sebuah array. Kode untuk oh mengembalikan array dengan desain dan kami memaksa nggak dan ya untuk mengembalikan array juga. Karena itu sintaksnya:

(c = eval("[code0];code1;...".split`;`[index])).map || s.push(c)
