Script che genera uno script che stampa un determinato input

29

Scrivi un pezzo di codice che accetta una stringa come input e genera un pezzo di codice nella stessa lingua che, una volta eseguito, produrrà la stringa di input iniziale.

Deve essere in grado di gestire qualsiasi combinazione di caratteri AZ, az e 0-9.

Esempio in Python:

import sys
print "print('" + sys.argv[1]  + "')"

Dato l'ingresso di testing123, tornerà print('testing123').

Dato che si tratta di code-golf , vincerà la risposta più breve in byte.

L'input deve essere una stringa? O può essere un numero intero?
— Shaggy,
Deve essere in grado di gestire sia input di numeri interi sia stringhe.

Possiamo generare una funzione secondo i defauts su meta?

Spiegazione:

Un programma vuoto in pl è semplicemente un programma cat, che fornisce esattamente lo stesso input.

In pl, tutti i caratteri ASCII sono essenzialmente variabili, ma quando la variabile non esiste (ancora), si assume che facciano parte di una stringa.

Sapevo che c'era una lingua come questa, ma non riuscivo a trovarla però :(

Allo stesso modo, vedi Cat, che è un linguaggio interpretato come Python. Le distribuzioni Linux più moderne vengono fornite con un catinterprete. ;)

Questa soluzione funziona anche per /// se si considera che l'input viene aggiunto al codice sorgente del programma (poiché /// non ha alcun meccanismo per l'input). /// è una delle molte lingue (penso) in cui i caratteri alfanumerici all'inizio del programma vengono semplicemente emessi.

L'output richiede un interprete che esegue il wrapping sul underflow della memoria e ha EOI = 0. TIO ha un tale interprete.

Spiegazione

--[>+<++++++]inizializza il nastro con un singolo +.

Il ciclo di input:

,[[->.<]>+++.--.-<,]
,                     take input
 [                ,]  while input is nonzero:
  [->.<]                  output `+` input times
        >+++.             output `.` (`+` + 3)
             --.          output `,` (`.` - 2)
                -<        restore `+` and move back to input

+1. Non conosco Brainfuck, ma non riesco a immaginare di provare a risolvere un problema come questo con esso.
— Jakob,
Puoi salvare 1 byte sostituendo il +++++++++++++++con +++[>+++++<-]>(Da costanti brainfuck )
— Graviton
@Graviton Oh, bello, grazie

non lo hai sostituito nella spiegazione

Non conosci Brainfuck? Ti insegnerò in un commento! Iniziamo su un nastro di 0's, con un puntatore a un valore. +incrementa il valore, -decrementa il valore, >sposta il puntatore a destra, <sposta il puntatore a sinistra, ,legge l'input sul puntatore come carattere ASCII, .genera il valore del puntatore come carattere ASCII, [avvia un loop e ]passa al corrispondente [se il il valore del puntatore non lo è 0. Non sono bravo a spiegare, ma è così facile Brainfuck. E Nice golf Conor!

Spiegazione

Innanzitutto, un rapido aggiornamento su Mornington Crescent:

  • ogni stazione può contenere una stringa di lunghezza arbitraria o un bigint
  • c'è anche un accumulatore che contiene anche una stringa o un bigint
  • tutte le stazioni iniziano con il proprio nome come valore
  • all'inizio, l'accumulatore contiene l'input del tuo programma
  • ogni volta che vai in una stazione, il valore della stazione e l'accumulatore vengono scambiati
  • alcune stazioni sono speciali e ignorano questo comportamento
  • la linea che usi per raggiungere una stazione non ha importanza
  • si inizia a Mornington Crescent
  • per terminare il programma, vai anche a Mornington Crescent
  • alla fine, viene stampato il valore dell'accumulatore

Poiché la stampa di stringhe è difficile (vedere il programma "Hello, World!" Di Mornington Crescent di Martin Ender ), avremo bisogno di un modello semplice che possa essere utilizzato per produrre stringhe generiche. Dal momento che la lunghezza dei programmi generati non ha importanza, mi sono deciso su questo:

Take Northern Line to Bank
Take Northern Line to Bank
Take District Line to Paddington

Dovremo generare ciascun personaggio separatamente e concatenarli, poiché l'approccio di sottostringa usato da Martin è molto più difficile da implementare nel caso generale. Paddington è la stazione che esegue la concatenazione di stringhe. Quando arrivi a Paddington, succede quanto segue:

accumulator, paddington = paddington + accumulator, accumulator

Questo comportamento viene utilizzato per inizializzare Paddington sulla stringa vuota che si presume sia l'input.

Take District Line to Victoria
Take Victoria Line to Seven Sisters
Take Victoria Line to Euston
Take Victoria Line to Euston
Take Northern Line to Bank

Vai a Seven Sisters, che imposta l'accumulatore su 7 e conservalo in banca. La banca è l'unico modo per copiare i valori: Hammersmith è una copia di sola lettura del valore della banca.

Take District Line to Hammersmith
Take District Line to Cannon Street
Take District Line to Hammersmith
Take District Line to Cannon Street
Take District Line to Bank

Dividi 7 per 7 per ottenere 1, un divisore di tutti i valori ASCII che dobbiamo supportare.

Take District Line to Hammersmith
Take District Line to Upminster

Per ogni personaggio, inizia copiando 1 in Upminster.

Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Upminster
Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Upminster
Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Upminster

Aggiungi altri se necessario.

Take District Line to Hammersmith
Take District Line to Upminster
Take District Line to Bank
Take District Line to Bank
Take Northern Line to Charing Cross
Take Northern Line to Charing Cross
Take Bakerloo Line to Paddington
Take Bakerloo Line to Paddington
Take Bakerloo Line to Charing Cross
Take Northern Line to Embankment

Termina andando su Upminster solo una volta, per conservare il nuovo valore nell'accumulatore invece di memorizzarlo di nuovo. Portalo su Charing Cross per trasformare il valore ASCII in un carattere e aggiungerlo alla stringa. Le ultime due righe sono lì perché ho letto male le specifiche, quindi mi fermerò qui e golferò prima il mio programma.

(disclaimer: ho appena imparato questa lingua) Circa lo stesso identico approccio a cui riesco a pensare (7/7 = 1). Ma perché non impostare Upminister solo una volta all'inizio del programma?

iè una funzione che inserisce una stringa specificata in corrispondenza di un indice specificato nell'input. Qè una variabile che assume per impostazione predefinita un segno di virgolette "e, poiché non viene fornito alcun indice, per impostazione predefinita è 0. Il risultato finale è un segno di virgolette inserito all'inizio della stringa, che Japt termina automaticamente durante l'esecuzione.

Funziona su stringhe contenenti qualsiasi cosa tranne ", {o \, anche se ovviamente la stringa è garantita da caratteri alfanumerici, quindi non importa.

@(t)['disp ',t]

Ho completamente ignorato il fatto che il programma deve solo gestire caratteri alfanumerici o, soprattutto, non ha bisogno di gestire caratteri spaziali. Questo significa che possiamo usare la sintassi 'command', che usa significativamente meno byte.

MATLAB, 27 byte

Per completezza, ecco una versione in grado di gestire input arbitrari:

@(t)['disp(',mat2str(t),41]

Definisce una funzione anonima che accetta la stringa te la converte nel programma. Curiosamente, questo non funziona in Octave, che sembra avere idee diverse su cosa mat2strdovrebbe fare.

— Sanchises
fonte
Non posso provarlo, ma penso: @(t)['disp ',mat2str(t)]dovrebbe funzionare ...?
— Stewie Griffin,
@StewieGriffin Non funziona perché mat2straggiunge le virgolette, che non sono necessarie nella sintassi dei comandi. Ho avuto la sintassi della funzione combinata con mat2strper gestire gli spazi nell'input, ma nel rileggere la sfida, questo non è effettivamente necessario, tagliando il conteggio dei conti quasi a metà. Grazie!
— Sanchises,
Ho pensato che le virgolette fossero necessarie se ci fossero spazi nell'input ma potrei sbagliarmi. Non ho notato che l'ingresso era solo alfanumerico ...
— Stewie Griffin,
In questo modo (ungolfed).
— Stewie Griffin,
@StewieGriffin Hai ragione, ho giudicato male il modo in cui funziona la sintassi dei comandi. Tuttavia, la sintassi dei comandi sembra essere piena di sorprese: provala online!

Lotto 11 byte

Sono sicuro che c'è via per ridurlo, ma questo è piuttosto piccolo.

set/p=echo

La ripartizione:

set             ::Define new variable
   /p           ::Create prompt
     =          ::Define a variable in prompt
      echo      ::Prompt begins with 'echo '

In inglese:

All'utente viene chiesto di immettere una frase iniziale echo. Quindi l'utente può digitare qualunque cosa e il programma termina (es.; echo hello world!). Questo ci lascia con un programma che, una volta eseguito, verrà emesso hello world!.

Sì, lo spazio bianco dovrebbe essere lì

— Graviton
fonte
Non conosco batch (e questo è molto tempo fa), ma questo sembra sbagliato. La parte non echoverrebbe eco nella console e non l'output del programma?
— Jakob,
@Jakob sorprendentemente no, è essenzialmente equivalente dal punto di vista funzionale all'esempio di pitone fornito nella sfida iniziale.
— Graviton,
Oops - quello che volevo dire è che dubito che il programma produca il testo digitato dall'utente. Probabilmente ha appena fatto eco alla console, giusto?
— Jakob,
@Jakob Right, che equivale alla stampa. L'esempio stampa una funzione di stampa mentre il mio echo una funzione di eco.
— Graviton,
OK, ma l'esempio stampa l'intero programma allo standard. Il tuo programma stampa solo echo allo standard. In effetti, (presumo) se l'input proviene da un file o pipe, tutto ciò che vedresti è il prompt. È stato consentito questo tipo di output?

In Vim, ipassa alla modalità di inserimento e consente l'inserimento di testo. In questo caso, inserisce solo il idavanti al testo di input (per creare il secondo programma). V è compatibile con Vim, ma aggiunge un implicito <esc>alla fine del programma, quindi non devo preoccuparmene qui.

Avvolge semplicemente la stringa tra virgolette usando &D, che è l'equivalente di MATLAB, MATLAB mat2str, una funzione appositamente creata per creare qualcosa che, quando evallo desse, darà la matrice originale (o in questo caso, stringa).

Come funziona

# //Takes the input and places it onto the string stack
  //This is then output implicitly

{input} //The next program then consists of the input string
        //This is then placed directly onto the string stack
        //Then output implicitly

Un'alternativa, anche a 1 byte è:

$

Funziona come sopra ma accetta solo la prima riga di input. Visto che l'input sarà sempre e solo [A-Za-z0-9]questo va bene.
