¡Los fragmentos de pila se agregaron recientemente a PPCG ! ¡Con reminiscencias de JSFiddle , los fragmentos de pila permiten que HTML, CSS y JavaScript se ejecuten directamente en las publicaciones !

Aquí hay un fragmento de pila muy simple:

alert('This is JavaScript')

h3 { color: red } /* This is CSS */

<h3>This is HTML</h3>

Expandir fragmento

Esta característica de Stack Exchange sería muy útil para nosotros si se admitieran idiomas además de JavaScript. (Las respuestas a los desafíos podrían probarse en el acto, las entradas de ejemplo podrían generarse dinámicamente, etc.) Aquí es donde entras tú.

Desafío

El objetivo de este desafío es escribir un intérprete para algún lenguaje de programación usando Stack Snippets y JavaScript. El punto es hacer algo que se pueda copiar y usar fácilmente en futuras preguntas y respuestas de PPCG.

Más o menos, debe crear un fragmento de pila que tenga un botón "Ejecutar" y dos cuadros de texto, uno para el código y otro para la entrada. Al hacer clic en el botón Ejecutar, se ejecutará el código (escrito en el idioma que está interpretando) en la entrada y se mostrará el resultado (probablemente en otro cuadro de texto). El fragmento debe ser algo parecido a cjam.aditsu.net o la respuesta de muestra .

Para la mayoría de los idiomas, tendría sentido que la entrada y la salida representaran stdin y sdout respectivamente, y es posible que tenga otro cuadro de entrada para la línea de comando. Pero no todos los idiomas tienen mecanismos de E / S tan tradicionales. HQ9 + , por ejemplo, ni siquiera tiene entrada, lo que hace que un cuadro de texto no tenga sentido. Así que siéntase libre de tomarse algunas libertades, diseñar alrededor del lenguaje, no esta especificación. El requisito principal es que su idioma sea "ejecutable" en un fragmento de pila en el sentido aceptado del término.

Notas

Implementar todas las características de su idioma, aunque es ideal, no es obligatorio. Algunas cosas como leer y escribir archivos o importar bibliotecas pueden ser difíciles de manejar o imposibles. Concéntrese en hacer un intérprete que maximice la utilidad para usar en este sitio.
Publicar un intérprete de "lenguaje X a JavaScript" que no escribiste está bien (con atribución).
Stack Exchange limita las respuestas a 30,000 caracteres , así que planifique en consecuencia si es probable que su intérprete sea largo.
Es mejor que haga que una versión de su intérprete sea lo más fácil posible para incluir en publicaciones futuras. Por ejemplo, en la respuesta de muestra , se proporciona el Markdown sin procesar para todo el fragmento, con lugares obvios para poner código y entrada.

Aunque esta pregunta pretende ser más un compendio de intérpretes que un desafío adecuado, sigue siendo un concurso de popularidad , por lo que gana la respuesta más votada.

No sería muy divertido, pero la respuesta más práctica para lenguajes más difíciles como Python probablemente sería simplemente subcontratarlo.

Python 2 (sin STDIN)

Gracias a Skulpt , se ha vuelto muy fácil escribir un intérprete de Python.

function out(text) {
  var output = document.getElementById("output");
  output.innerHTML = output.innerHTML + text;
}

function builtinRead(x) {
  if(Sk.builtinFiles === undefined || Sk.builtinFiles["files"][x] === undefined)
    throw "File not found: '" + x + "'";
  return Sk.builtinFiles["files"][x];
}

function run() {
  var program = document.getElementById("python-in").value;
  var output = document.getElementById("output");
  
  output.innerHTML = "";
  
  Sk.canvas = "canvas";
  Sk.pre = "output";
  
  Sk.configure({
    output: out,
    read: builtinRead
  });
  
  try {
    Sk.importMainWithBody("<stdin>", false, program);
  }
  catch(e) {
    throw new Error(e.toString());
  }
}

Editar: reelaboré toda la GUI ahora. Estoy mucho más feliz con eso. Algún tipo de función de punto de interrupción sería genial, pero probablemente sea demasiado para esto. Puntos abiertos que probablemente volveré a visitar:

Permitir un tablero infinito
Mostrar la pila al recorrer el programa sería genial

Como acabo de implementar este intérprete para este desafío, no se ha probado exhaustivamente. Sin embargo, lo probé con una variedad de programas diferentes ahora y parece funcionar bien.

¡Agradable! ¿Tenemos que ingresar manualmente el tamaño de la placa? Parece que si no lo hacemos, resaltar tiende a ir por todas partes. (prueba con el primer programa aquí: en.wikipedia.org/wiki/Befunge#Sample_Befunge-93_code )

— Sp3000

@ Sp3000 Solo tiene que ingresarlo si desea cambiarlo (el valor predeterminado es el original 80x25). El programa funciona bien para mí. "Por todas partes" es de lo que se trata Befunge. Lo único que no es tan bueno es que tienes que recorrer todos los espacios en blanco del tablero individualmente, pero lo arreglaré. Sin embargo, es técnicamente correcto. Si sientes que algo es raro, ¿tal vez puedas hacer un gif / video de cómo te parece?

— Ingo Bürk

@ Sp3000 Una cosa: si presiona "Ejecutar", el resaltado parece extraño porque va demasiado rápido. Si no lo ha hecho antes, simplemente intente "Paso" para recorrer el comando del programa para el comando. Alternativamente, establezca los pasos por marca en 1 y presione Ejecutar para obtener una animación más fluida.

— Ingo Bürk

Ajaja sí, por "todo el lugar" quise decir el hecho de que todo el espacio en blanco es atravesado ¿Planea hacer que el programa detecte el tamaño de la placa en el futuro? (Si tienes tiempo)

— Sp3000

1

@ Sp3000 El tamaño de la placa es propiedad del intérprete, no del programa. Originalmente, las tablas Befunge tienen un tamaño fijo. Pero puede permitir un tamaño infinito que estoy planeando hacer. También planeo omitir espacios en blanco consecutivos en un solo paso.

TI-BASIC

porque a quién no le gusta TI-Basic?

Quería contribuir a esto, así que elegí un lenguaje que (en mi humilde opinión) es un poco más complicado que, por ejemplo, Deadfish, pero que está bajo mi control. Sé mucho sobre mi calculadora, así que elegí esto.

Sin embargo, no tengo experiencia previa con JavaScript / CSS / HTML. Este fue mi primer programa. Eso significa...

¡Señale los errores que encuentre en mi código!

Dicho esto, esta es una versión limitada de TI-Basic. Continuaré implementando cosas a medida que me vaya acercando a ellas.

Características a partir de ahora

palabras clave de control comunes (if, then, else, end)
Todos los bucles disponibles (mientras, repetir, para)
comando disp
Operadores aritméticos de JavaScript, a través de eval
Liza
Construido en colon-ator automático (compruébelo usted mismo)
Valores aleatorios de variables no inicializadas, como su calculadora
matemáticas limitadas: sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, log, ln, int, round, abs.
constantes pi y e como variables
Mensaje, entrada, pausa (¡Sí!)
escribe en la salida durante la ejecución (gracias a pseudonym117)
capacidades simples de encendido / apagado de píxeles / pantalla clara

Libertades tomadas

admite nombres de variables de varios caracteres. Desafortunadamente, esto significa que abes una variable, no el valor a*b. Este límite de nombre de variable de un solo carácter me volvió loco en mi calculadora.
ignorando "goto" y "lbl". Tenían errores incluso en la calculadora a menos que lo hicieras de cierta manera.
Vamos a ignorar prgm, OpenLib y ExecLib porque no hay archivos externos / otros

Lo que aún queda por hacer

~~Algún tipo de lienzo para dibujar (¡próximamente!)~~ Más cosas de dibujo
~~De alguna manera prompty inputcomandos en la ventana de texto (sugerencias, ¿alguien?)~~
Soporte para (el resto de) operaciones matemáticas de calculadora (hay CUBOS)
Suppot para Anstravesuras de palabras clave.
Soporte para el resto de palabras clave CTL
Alguna forma de admitir una forma de getkey, aunque la mayoría de los idiomas hoy en día están controlados por eventos ... Quizás podría ser la última tecla presionada.
~~No sé si esto es cierto, pero JavaScript parece pensar primero, luego mostrar en un área de texto, en lugar de mostrar a medida que avanza.~~
No hay belleza CSS / HTML

Todavía no sé mucho sobre JavaScript. Si alguno de los anteriores es posible / imposible, hágamelo saber.

¡Estoy haciendo cosas con este código! Encontré un error: en la línea ~ 93, tienes lineProcessing.clearInterval();; esto en cambio debería ser clearInterval(lineProcessing);.

@ CᴏɴᴏʀO'Bʀɪᴇɴ Siéntase libre de editarlo y cambiarlo. Ha pasado un tiempo desde que miré este código. Además, estoy un poco abrumado en el trabajo escolar en este momento, por lo que podría pasar un tiempo hasta que cambie algo.

En mi navegador, todo está contenido dentro del fragmento expandido, pero no soy un experto en compatibilidad del navegador, así que no puedo garantizar que sea igual para todos.

Caracteristicas

El ajuste de celdas y el comportamiento EOF se pueden configurar
Se puede pasar por alto el tiempo de espera
El programa se puede detener a mitad de la ejecución
Un bonito y pequeño botón claro
Todo esto dentro de la caja de Stack Snippet (o al menos lo intenté) y registrando alrededor de 6k caracteres sin golf

Maravilloso *

Este intérprete probablemente está lleno de errores; Si encuentra alguno, hágamelo saber.

Esto admite todas las características de Marbelous excepto #include. También hay una opción para usar un tablero cilíndrico (las canicas empujadas por los lados del tablero reaparecen en el otro lado).

El intérprete también viene con muchas tablas presentes en los ejemplos en el repositorio para el intérprete de Python para Marbelous . Estas tablas se enumeran a continuación:

dec_out.mbl - Dp, Decout
hex_out.mbl - Hp, Hexo
fourwayincrement.mbl - Fwin
threewaysplit.mbl - 3W
bitwise_operations.mbl - Bitx, Bdif, Borr, Band, Bxor, Bnor
logical_operations.mbl - Tf, Nt, Lorr, Land, Lnor, Lxor, Cmpr, Eqal, Gteq, Lteq, Grtr, Less, Sort
replace_input.mbl - Replac
adder.mbl - Plus
arithmetic.mbl - Subt, Subo, Subful, Addo, Addful, Mult
wide_devices.mbl - Wideadditionfunc, Widesubtractfunc, Wbitleft, Wbitrght, Wbitfetchx, Mulx, Doblmult, Widemultiplyfunc

No incluye debe ser utilizado. Consulte el repositorio del intérprete de Python para obtener detalles sobre lo que hace cada una de estas tablas.

* Más información sobre Marbelous:

Nota: La salida gráfica (256x256 con doble buffer con color RGB de 24 bits) está disponible en este intérprete. Las siguientes tablas pueden usarse para este propósito:

{}{}{}{}{} - Set Pixel for Back Buffer (}0 - x, }1 - y, }2 - red, }3 - green, }4 - blue)
>< - Swap Buffers and Clear Back Buffer (}0 - anything)
@f@f@f - Get Pixel from Front Buffer (}0 - x, }1 - y, {0 - red, {1 - green, {2 - blue)
@b@b@b - Get Pixel from Back Buffer (}0 - x, }1 - y, {0 - red, {1 - green, {2 - blue)

Tenga en cuenta que haber Use Draw Buffersmarcado (requerido para la salida gráfica) podría ralentizar el intérprete, y que la salida gráfica es lenta.

Actualización : buffers cambiados para usar lienzo en lugar de divisiones de 1x1 píxeles el dibujo debería ser mucho más rápido ahora.

<!-- end snippet -->

Para usarlo, simplemente cópielo en una nueva publicación y coloque su código en las líneas entre BEGIN_CODEy END_CODE_BEGIN_INPUT, y su entrada en las líneas entre END_CODE_BEGIN_INPUTy END_INPUT. El intérprete hará el resto. Tenga en cuenta que nada necesita ser sangrado.

Yo diría que esta BEGIN...ENDtécnica es actualmente la mejor manera de escribir estos intérpretes en términos de facilidad de uso futuro porque ...

Cuando se procesa, solo hay un bloque de código (el HTML) y solo una línea es "extra".
El usuario que escribe el fragmento puede ver exactamente dónde colocar su código y entrada. No tienen que buscar la etiqueta de área de texto adecuada.
Los usuarios que leen la publicación pueden distinguir fácilmente el código sin siquiera ejecutar el fragmento. Por supuesto, cuando se ejecuta el fragmento, el código es obvio.
Solo se interrumpe cuando los identificadores de inicio / fin aparecen en sus propias líneas dentro del código o la entrada. Pero esto es poco probable, y pueden cambiarse si es absolutamente necesario.
Es independiente. Todo el código está ahí. (Sé que esto podría ser imposible para un intérprete más grande, pero uno de los puntos de Stack Snippets era combatir los enlaces muertos a JSFiddle y tal, por lo que la autocontención es buena).
Se podría ampliar para adaptarse a cualquier cantidad de entradas (basadas en texto).

El fragmento a continuación es la versión general no minimizada, completa con un ejemplo y un poco más de estilo.

Mostrar fragmento de código

function example() {
  document.getElementById('code').value = "var lines = x.split('\\n')\nvar sum = 0\nfor (var i = 0; i < lines.length; i++) {\n  var val = parseInt(lines[i])\n  if (!isNaN(val)) {\n    sum += val\n  }\n}\nreturn sum"
  document.getElementById('input').value = '1\n2\n3'

Brainfuck (con depurador básico)

Vi la respuesta de brainfuck y pensé: ¿sabes qué sería increíble? Si pudiera fingir, entiendo lo que está haciendo el código Brainfuck. Y, por lo tanto, hice un intérprete y depurador básico. El depurador es LENTO, pero funciona bastante bien, aunque hasta ahora no he implementado puntos de interrupción (en la lista de tareas pendientes).

Nota: la "máquina virtual" Brainfuck no se reinicia automáticamente después de ejecutar el código. Presione restablecer manualmente o la cinta tendrá los mismos valores que existían al final de la última ejecución del programa.

El depurador funciona mejor en pantalla completa.

QUE HACER:

agregar puntos de interrupción
agregar verificación de rango para cambiar la pila
indicador de progreso
haz que se vea mejor
agregar rebobinado para depurar
cambiar stdin a algún tipo de flujo?
código de golf un poco
?

Uso:

Para usar en un fragmento en algún lugar del sitio, cambie la primera línea del fragmento para incluir su código como "mycode".

Para ejecutar código sin depurador, simplemente presione ejecutar. Almacena la salida para medio millón de instrucciones antes de actualizar stdout.

Para depurar, comience presionando el botón de depuración. El botón de paso pasará a la siguiente instrucción. El botón Ejecutar ejecutará todo el programa, pero un paso a la vez, actualizando la tabla de la pila en cada paso (por eso es tan lento). El tiempo entre instrucciones está determinado por el cuadro de entrada con ese nombre. El botón de pausa detiene la ejecución del código. Se puede reanudar presionando Ejecutar nuevamente.

Todos los valores en la pila se pueden cambiar en vivo a lo que quieras. Sin embargo, tenga cuidado, no verifica el rango si cambia el valor entero en la celda, por lo que si coloca 300 con un tamaño de pila de 8 bits, realmente no le importa y no lo corregirá hasta la próxima vez que aumente.

Esto es bastante bueno. ¡Amo al depurador!

Japt

Japt ( Ja vascri pt abreviada) es un lenguaje que he diseñado en septiembre de 2015. Debido a ser ~~perezoso~~ ocupado, no he creado un intérprete hasta principios de noviembre. Puede encontrar el intérprete oficial y los documentos aquí .

Nota: Si tiene alguna pregunta, sugerencia o informe de error, publíquelo en la sala de chat de Japt .

Dato curioso: originalmente era el intérprete principal (y de hecho el único intérprete). Puede ver esto si mira a través del historial de revisiones .

¿Japt tiene un Github?

@ Vɪʜᴀɴ Todavía no, pero configuraré una en las próximas 24 horas.

@ Vɪʜᴀɴ Debería haber dicho 24 minutos. ;) Aquí tienes. Léame está en camino.

Debería usar rawgit.com en lugar de raw.githubusercontent.com: a Chrome no le gustan las cosas de tipo MIME.

Expandir fragmento

El programa de ejemplo anterior es mi programa de cuatro cuadrados juntos : toma la entrada 2 ⁿ * 193 y genera 3 ^a * 5 ^b * 7 ^c * 11 ^d , de modo que a ² + b ² + c ² + d ² = n.

Que hacer

Generador de fragmentos
Permitir la notación de factorización para fracciones también
Validación de entrada menos terrible
Limpia el código para ser mejor
Permita la impresión de registros en condiciones especiales (por ejemplo, solo 2se establece el registro , en el caso del generador principal de Conway). Actualmente solo los programas que terminan producen cualquier salida.
Optimizaciones de rendimiento?

Uso

Las fracciones en el código se dividen por [\s,]+, lo que le permite separar fracciones por líneas nuevas, espacios o comas (o pestañas, o incluso cualquier combinación de lo anterior, si está loco)
La entrada puede estar en notación de factorización, p. Ej. 2^5 * 3^7 * 11
El generador de fragmentos llegará algún tiempo después

Preludio

Tal vez pueda aumentar un poco la adopción de Prelude si la gente solo puede jugar con ella en sus navegadores, así que aquí hay un intérprete de JavaScript. Se basa en el ingenioso intérprete Brainfuck de Sp3000 , cuya característica asesina es la ejecución interrumpible y un tiempo de espera opcional.

var ITERS_PER_SEC = 100000;
var TIMEOUT_MILLISECS = 5000;
var ERROR_LOOP_MISMATCH = "Mismatched parentheses";
var ERROR_LOOP_MULTI = "Multiple parentheses in the same column";

var ERROR_INTERRUPT = "Interrupted by user";

var code, input, timeout, num_input, num_output, loop_stack, loop_map;
var running, start_time, code_ptr, width, input_ptr, voices, iterations;

Expandir fragmento

Alternativamente, aquí hay un JSFiddle .

El intérprete está prepoblado con mi quine , pero puede encontrar fácilmente más programas de ejemplo para jugar buscando respuestas Prelude mías .

Se implementan todas las características de Prelude. El único inconveniente es la falta de aritmética de precisión arbitraria, debido al tipo de número de JavaScript. Podría arreglar eso en algún momento, ya que solo necesito admitir sumas y restas para enteros arbitrarios.

La entrada y la salida son generalmente los valores de bytes de caracteres individuales, pero el intérprete viene con dos banderas para leer y / o escribir números (firmados) en su lugar.

Que hacer

Añadir versión minimizada para copiar.
Soporta aritmética de precisión arbitraria.
Añadir generador de fragmentos.

Para preinicializar el cuadro de código, simplemente coloque algo entre las etiquetas de área de texto. Del mismo modo, al agregar checked="true"la etiqueta de la casilla de verificación, puede activar el modo ASCII / Unicode de manera predeterminada (como se ve arriba).

Tenga en cuenta que Deadfish en sí mismo no tiene salida ASCII en su especificación original, solo lo puse para preguntas que pueden permitir "la próxima cosa más cercana". Si le preocupa que las reglas de una pregunta no permitan Deadfish debido a esto, siempre puede ver algo como Deadfish ~ que tiene salida ASCII.

El ejemplo que se muestra es del tema Feliz cumpleaños .

Esto no se ajusta estrictamente al requisito, es mi visión sobre cómo podríamos hacer uso de los fragmentos de pila.

No me gusta la cantidad de repeticiones, especialmente la necesidad de incluir HTML personalizado para otro botón Ejecutar.

En mi vision:

coloque una sola <script>etiqueta para incluir un marco simple y el intérprete real
coloque el script en el área CSS (el resaltado de sintaxis puede ser horrible)
use el botón Ejecutar fragmento de código existente para ejecutar el código
obtener la salida en el marco del fragmento

Por ahora no se ha decidido cómo sería mejor especificar la entrada.

debería haber una manera de incluir fácilmente la entrada también, supongo

— SztupY

Ciertamente, @SztupY. Por ahora no estoy decidido si incluir la entrada también en la pieza CSS o en la HTML. No usaría la pieza de JavaScript para eso, ya que los navegadores lo ejecutarán antes y algún código puede generar un bucle sin fin en JavaScript. Lamentablemente, no hay otra manera, ya que otras piezas no se copian en el servidor de fragmentos de pila. :(

— manatwork

Creo que el código está bien en el CSS, y la entrada puede ir después de las <script>etiquetas (tal vez en un contenedor pequeño, por ejemplo <pre>, para que el script pueda acceder a él. Espero que un pre no distorsione demasiado la entrada).

— SztupY

Aparecería una A <pre>(o generalmente cualquier etiqueta) y la sintaxis resaltada en verde. Como JavaScript puede extraer la parte de entrada de todos modos, no incluiría un marcado adicional. La principal diferencia entre usar la pieza CSS frente a la pieza HTML es que CSS no aparece en el documento, mientras que HTML sí. Aún indeciso.

JavaScript ES7

Esto le permite ejecutar el código ES6 / 7 en cualquier navegador.

Insomnio

Las especificaciones son ambiguas sobre la semántica de las instrucciones 8 y 9, por lo que no se implementan.

Siéntase libre de mejorarlo para admitir las instrucciones 0 a 7. También hay un código incompleto para ejecutar el programa en cámara lenta, pero tenía errores, así que lo eliminé de la interfaz.

function toAsciiValue(t) {
    var i = 0;
    var a = "";
    for (i = 0; i < t.length; i++) {
        a += t.charCodeAt(i);
    }
    return a;

HQ9 +

Dado que Calvin's Hobbies incluso usó HQ9 + como ejemplo, decidí escribir una implementación rápida para ello. Bueno, implementación parcial, ya que decidí dejar fuera el acumulador (puede que me odies por eso).

El intérprete es, digamos, parcialmente golfista. No sé por qué lo jugué, pero en realidad no.

(function () {
    var bottles = (function beerMe(amount) {
        return "012, 01.\n3, 412.5".replace(/\d/g, function (c) {
            return [amount || "No more", " bottles of beer", " on the wall", amount ? "Take one down, pass it around" : "Go to the store and buy some more", ((amount || 100) - 1) || "no more", amount ? "\n\n" : ""][c];
        }) + (amount ? beerMe(amount - 1) : "");
    })(99);

    document.getElementById('run').onclick = function () {
        var source = document.getElementById('source').value,
            output = '';
        source.split('').forEach(function (command) {
            var index = ['H', 'Q', '9'].indexOf(command);
            (index + 1 && (output += ['Hello, world!', source, bottles][index], !0)) || alert('illegal command: ' + command);
        });

        document.getElementById('stdout').value = output;
    };
})();

#source, #stdout {

Realmente creo que este lenguaje merecía tener un intérprete y parecía lo suficientemente simple como para que un no programador como yo lo intentara. Espero haberlo hecho bien. Parece funcionar para los ejemplos que he probado. Gran parte del código está plagiado de otras respuestas en esta pregunta. Mis disculpas a los programadores reales por ahí si he cometido algún pecado capital en mi código :)

He puesto el ejemplo 'Reverse STDIN' de la página de Esolangs.

var ITERS_PER_SEC = 100000;
var TIMEOUT_SECS = 50;
var ERROR_INTERRUPT = "Interrupted by user";
var ERROR_TIMEOUT = "Maximum iterations exceeded";
var ERROR_LOSTINSPACE = "Beam is lost in space";

var code, store, beam, ip_x, ip_y, dir, input_ptr, mem;
var input, timeout, width, iterations, running;

function clear_output() {
document.getElementById("output").value = "";
document.getElementById("stderr").innerHTML = "";
}

function stop() {

¿Cómo no me di cuenta de esto antes? ¡Esto es genial! Me encanta ver idiomas rescatados del Pozo de Implementación. ;)

Espero que no te importe, pero limpié un poco la sección JS.

— ETHproductions

@ETHproductions No tengo ningún problema con eso en absoluto. No soy un programador real como mencioné anteriormente, pero realmente quería algo para probar algunas ideas que despertaste con tu respuesta al desafío Hello World.

La función de tiempo de espera actualmente no parece funcionar. Si inserto un bucle infinito, se bloquea el navegador, y recuerdo una vez que intenta imprimir todos los caracteres ASCII a partir !de ~, y tener siempre el tiempo de espera después de los tres primeros, incluso con tiempo de espera de apagado. Echaré un vistazo a esto en un momento.

@ETHproductions que apareció con el fragmento que copié en gran medida para comenzar este. Debo admitir que he tenido algunos problemas con los tiempos de espera.

K5

Este es un contenedor simple y delgado alrededor de mi implementación de K basada en JavaScript, oK , y hace referencia al repositorio de github. Ya he construido una interfaz mucho mejor basada en el navegador. Ok implementa una porción muy sustancial de K5, aparte de IO, y se ha utilizado en el pasado para resolver una serie de problemas aquí en el desbordamiento de la pila. El código no es golf, per se, pero está muy por debajo de 1000 líneas, incluidos los comentarios, el analizador, todas las operaciones primitivas, el intérprete y la bonita impresora.

* {
  font-size:12px;

  overflow-x:hidden;
  width:90%;

    	var ret  = run(parse(code), baseEnv());
    	document.getElementById("output").value = format(ret);

Ouroboros

Un lenguaje esotérico creado por mí, DLosc, en octubre de 2015. El modelo de ejecución se basa en que cada línea de código es una serpiente ouroboros . El control pasa de la cabeza a la cola y vuelve a la cabeza; Las instrucciones permiten que la serpiente trague parte de su cola o regurgite lo que ha tragado, cambiando así el flujo de ejecución. Todas las serpientes se ejecutan en paralelo. Los datos se almacenan en una pila compartida, así como en una pila individual para cada serpiente. Para obtener más información, programas de muestra y el intérprete más actualizado, consulte el repositorio de Github .

oOo CODE

Un intérprete muy simple para oOo CODE (la primera vez que uso javascript). oOo CODE es un lenguaje esotérico basado en brainfuck que usa mayúsculas y minúsculas para almacenar su información, el texto real no importa. Como oOo CODE se basa en brainfuck, reutilicé una de las respuestas de brainfuck y agregué una función para traducir oOo CODE a brainfuck.

Necesita más puntos y comas. ASI es obra del diablo.

— nyuszika7h

@ nyuszika7h Interesante, no sabía que funciona de esa manera ... (programador de python) El código sin punto y coma era de la respuesta original de Sp3000, así que no noté la falta de punto y coma.

@ Sp3000 No hay problema, escribí mi respuesta por diversión y para aprender un poco de JavaScript, no para la recompensa

STATA

Editar: agregado reemplazar y verificaciones para generar.

Tiene soporte para algunas partes de display, forvalues, list, generate y set obs. Además, tiene algunos soportes para la creación y uso de macro (variables de STATA). Admite suficientes operaciones para algunas de las respuestas más simples que se han publicado en este sitio, como Evolution of "Hello World!" , Genera la secuencia de Stöhr , Hazme un árbol del alfabeto (reemplaza las comillas simples con comillas dobles y haz 3 líneas en lugar de 1). Este es un trabajo en progreso, y espero continuarlo pronto, pero pensé que al menos pondría algo aquí por ahora.

Error: en una generateexpresión, solo _nse reemplaza el primero .

— LegionMammal978

Supongo que el método de reemplazo de JS solo reemplaza la primera instancia. ¿Existe alguna manera de cambiar esto?

str.replace(/_n/g,i+1)

Simplemente convierte Unary a Brainfuck. Esto podría combinarse fácilmente con uno de los intérpretes de Brainfuck para ejecutar el código Unary directamente, ¡sin necesidad de reinventar la rueda!

function interpret() {
  var result = "";
  var table = "><+-.,[]"
  var option = document.getElementById("option").checked
  var code = document.getElementById("code").value
  var number = option ? parseInt(code, 10) : code.length;
  number = number.toString(2)
  if (number.length % 3 == 1) {
    number = number.slice(1)
    for (var i = 0; i < number.length; i += 3) {
      var instruction = number[i] + number[i + 1] + number[i + 2]
      instruction = parseInt(instruction, 2)
      result += table[instruction];
    }
  } else {
    result = "Error: program binary cannot be split into triplets."
  }
  document.getElementById("result").value = result;

¿Qué, esto sigue siendo código golf, rr-right?

En una nota seria, implementé un montón de lenguajes esotéricos en JavaScript hace un tiempo, siéntase libre de usarlos, es bastante plug and play: https://dl.dropboxusercontent.com/u/69377299/lang%20js/ main.html

function run () {
  var code = document.getElementById("code").value;
  var inp  = document.getElementById("in").value;
  var ret  = x(code, inp);
  
  document.getElementById("out").value = ret;
}

function B(s,i,c) {
	i+=1+-c*2
	return s[i]==']['[+c]?i:B(s,s[i]==']['[+!c]?B(s,i,c):i,c)
}

function x(c, a) {
	var y, l=0, p=0, i=0, q=0, r='', t=[]
	for (; q<1000; q++) t[q] = 0

	for (;i<c.length; i++) {
		y = c.charCodeAt(i)
		p -= (y==60) - (y==62)
  		t[p] += y==44? (l>a.length? 0: a.charCodeAt(l++))-t[p]: -((y==45) - (y==43))
		if (y==46) r += String.fromCharCode(t[p])
		if (y==91 + (t[p]>0)*2) i = B(c,i,y==93)
	}

	return r;
}

Code: <input id="code"></input>
<button onclick="run()">Run</button>

Input: <input id="in"></input>

<br><br>
Output: <input id="out" disabled></input>
