Ja ist eine stapelbasierte Sprache mit einigen durch Leerzeichen getrennten Anweisungen:

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

Das letzte Element des Stapels wird immer am Programmende ausgegeben. Alle nicht alphanumerischen und nicht Leerzeichen werden ignoriert. Der gesamte Code ist klein geschrieben. Beispielprogramme:

Sie müssen einen Interpreter in möglichst wenigen Bytes schreiben. Hier ist eine JS-Implementierung (nicht gut gespielt!):

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{

Code: <textarea id = "code"></textarea>

Sie können davon ausgehen, dass alle beteiligten Ganzzahlen kleiner oder gleich 126 sind, reallyniemals mit einer Zeichenfolge mit mehreren Zeichen über dem Stapel ausgeführt werden und dass der Stapel niemals länger als 100 Elemente sein wird.

  • Die Eingabe kann eine Zeichenfolge oder eine Zahl sein.
  • Der Code kann beliebige Zeichen enthalten. Nicht übereinstimmende [a-z ]sollten ignoriert werden.

Mir ist ein Mangel an Testfällen aufgefallen. Ich habe in den Kommentaren dazu nichts gesehen, daher habe ich mich gefragt, wie sein Referenzprogramm ungültige Befehle ignoriert, während Ihr Programm sie möglicherweise als gültige Befehle ausführt, wenn die Summe der Zeichencodes mit einem gültigen Befehl übereinstimmt.

JavaScript (ES6), 218 215 204 203 Byte

Übernimmt die Programmzeichenfolge sund die Eingabe iin Curry-Syntax (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()

Wie?

Wir verwenden die perfekte Hash-Funktion parseInt(S, 35) % 156 % 9, um den Befehl S in einen Index in 0… 8 umzuwandeln, und verwenden diesen Index, um den auszuführenden JS-Code auszuwählen:

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()]

Die P- Funktion nimmt das letzte Element vom Stapel s und lädt es in k .

Wir verhindern, dass das Ergebnis einiger Anweisungen auf den Stapel zurückgeschoben wird, indem wir testen, ob die .map () -Methode definiert ist, dh ob das Ergebnis ein Array ist. Der Code für oh gibt ein Array von Entwurf zurück und wir zwingen nope und yep , auch Arrays zurückzugeben. Daher die Syntax:

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