Script que gera um script que imprime uma determinada entrada

29

Escreva um pedaço de código que aceite uma string como entrada e emita um pedaço de código no mesmo idioma que, quando executado, produzirá a string de entrada inicial.

Ele deve poder manipular qualquer combinação de caracteres AZ, az e 0-9.

Exemplo em Python:

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

Dada a entrada de testing123, ele retornará print('testing123').

Como esse é o código-golfe , a resposta mais curta em bytes será vencedora.

A entrada deve ser uma sequência? Ou pode ser um número inteiro?
— Shaggy
Deve ser capaz de lidar com entradas inteiras e de sequência.

Podemos gerar uma função de acordo com os padrões da meta?

pl , 0 bytes

Código:

Experimente online!

Explicação:

Um programa vazio em pl é simplesmente um programa de gato, produzindo exatamente o mesmo que a entrada.

Em pl, todos os caracteres ASCII são essencialmente variáveis, mas quando a variável ainda não existe, pl assume que eles fazem parte de uma string.

Eu sabia que havia uma linguagem como essa, mas não consegui encontrá-la :(

Na mesma linha, veja Cat, que é uma linguagem interpretada como Python. A maioria das distribuições Linux modernas é fornecida com um catintérprete. ;)

Essa solução também funciona para /// se você considerar que a entrada deve ser anexada ao código-fonte do programa (já que /// não possui mecanismo de entrada). /// é uma das muitas línguas (acho) em que caracteres alfanuméricos no início do programa são simplesmente gerados.

Você pode postar a versão ungolfed? ;)

A saída requer um intérprete que agrupe no fluxo insuficiente de memória e tenha EOI = 0. O TIO possui um intérprete.

Explicação

--[>+<++++++]inicializa a fita com um único +.

O loop de entrada:

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

+1. Não conheço Brainfuck, mas não consigo imaginar tentar resolver um problema como esse com ele.
— Jakob
Você pode salvar 1 byte, substituindo o +++++++++++++++com +++[>+++++<-]>(De constantes brainfuck )

@Graviton Oh, legal, graças

Você não conhece Brainfuck? Eu vou te ensinar em um comentário! Começamos com uma fita de 0's, com um ponteiro para um valor. +incrementa o valor, -diminui o valor, >move o ponteiro para a direita, <move o ponteiro para a esquerda, ,lê a entrada no ponteiro como um caractere ASCII, .gera o valor do ponteiro como um caractere ASCII, [inicia um loop e ]pula para o correspondente [se o O valor do ponteiro não é 0. Sou péssimo em explicar, mas é assim que Brainfuck é fácil. E bom golfe Conor!

Primeiro, uma rápida atualização sobre Mornington Crescent:

  • cada estação pode conter uma corda de comprimento arbitrário ou um bigint
  • há também um acumulador que também contém uma corda ou um bigint
  • todas as estações começam com seu próprio nome como valor
  • no início, o acumulador contém a entrada do seu programa
  • cada vez que você vai a uma estação, o valor da estação e o acumulador são trocados
  • algumas estações são especiais e substituem esse comportamento
  • a linha que você usa para chegar a uma estação não importa
  • você começa em Mornington Crescent
  • para finalizar o programa, você também vai a Mornington Crescent
  • no final, o valor do acumulador é impresso

Como a impressão de strings é difícil (consulte o programa Mornington Crescent "Hello, World!" De Martin Ender ), precisaremos de um modelo simples que possa ser usado para gerar strings genéricos. Como a duração dos programas gerados não importa, decidi sobre isso:

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

Precisamos gerar cada caractere separadamente e concatená-los, pois a abordagem de substring usada por Martin é muito mais difícil de implementar no caso geral. Paddington é a estação que executa a concatenação de cadeias. Quando você chega a Paddington, acontece o seguinte:

accumulator, paddington = paddington + accumulator, accumulator

Esse comportamento é usado para inicializar Paddington na cadeia vazia que é considerada a entrada.

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

Vá para Seven Sisters, que define o acumulador como 7, e armazene-o no banco. O Banco é a única maneira de copiar valores - Hammersmith é uma cópia somente do valor do Banco.

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

Divida 7 por 7 para obter 1, um divisor de todos os valores ASCII que precisamos oferecer suporte.

Take District Line to Hammersmith
Take District Line to Upminster

Para cada personagem, comece copiando o 1 para 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

Adicione mais conforme necessário.

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

Conclua indo até Upminster apenas uma vez, para manter o novo valor no acumulador em vez de armazená-lo novamente. Vá para Charing Cross para transformar o valor ASCII em um caractere e anexá-lo à string. As duas últimas linhas estão lá porque eu li mal a especificação, então vou parar por aqui e jogar meu programa primeiro.

iQ

ié uma função que insere uma sequência especificada em um índice especificado na entrada. Qé uma variável que tem como padrão aspas "e, como não há nenhum índice fornecido, esse padrão é 0. O resultado final é uma aspas inserida no início da string, que o Japt termina automaticamente ao executar.

Isso funciona em strings que contêm qualquer coisa ", exceto , {ou \, embora, é claro, é garantido que a string consiste em caracteres alfanuméricos, portanto isso não importa.

@(t)['disp ',t]

Experimente online!

Eu ignorei completamente o fato de que o programa só precisa manipular caracteres alfanuméricos ou, principalmente, não precisa manipular caracteres de espaço. Isso significa que podemos usar a sintaxe 'command', que usa significativamente menos bytes.

MATLAB, 27 bytes

Para completar, aqui está uma versão que pode lidar com entradas arbitrárias:

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

Define uma função anônima que pega a string te a converte no programa. Curiosamente, isso não funciona no Octave, que parece ter idéias diferentes do que mat2strdeve fazer.

— Sanchises

Não posso testar isso, mas penso: @(t)['disp ',mat2str(t)]deve funcionar ...?
— Stewie Griffin
@ StewieGriffin Isso não funciona porque mat2stradiciona aspas, que não são necessárias na sintaxe do comando. Eu tinha a sintaxe da função combinada mat2strpara lidar com espaços na entrada, mas, ao reler o desafio, isso não é realmente necessário, cortando o número de bytes quase pela metade. Obrigado!
— Sanchises
Eu pensei que as aspas eram necessárias se houvesse espaços na entrada, mas eu poderia estar errado. Eu não percebi que a entrada foi de apenas alfanumérico ou ...

Lote 11 bytes

Tenho certeza de que há distância para diminuí-lo, mas isso é bem pequeno.

set/p=echo

O colapso:

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

Em inglês:

O usuário é solicitado a inserir uma frase inicial echo. Em seguida, o usuário pode digitar o que quer e o programa termina (por exemplo; echo hello world!). Isso nos deixa com um programa que, quando executado, será exibido hello world!.

Sim, o espaço em branco deve estar lá

Não sei lote (e isso é de muito tempo atrás), mas isso parece errado. A echoparte não seria ecoada em texto no console e não seria programada?
— 19418 Jakob
@Jakob, supostamente não, é essencialmente funcionalmente equivalente ao exemplo de python dado no desafio inicial.
— Graviton
Opa - o que eu quis dizer é que duvido que o programa envie o texto que o usuário digita. Provavelmente está ecoando no console, certo?
— Jakob
@Jakob Right, que é equivalente à impressão. O exemplo imprime uma função de impressão enquanto o meu reproduz uma função de eco.
— Graviton
OK, mas o exemplo imprime o programa inteiro na saída padrão. Seu programa imprime apenas echo na saída padrão. De fato, (presumo) se a entrada vier de um arquivo ou canal, tudo o que você verá é o prompt. Esse tipo de saída foi permitido?

No Vim, imuda para o modo de inserção e permite inserir texto. Nesse caso, apenas insere o itexto na frente do texto de entrada (para criar o segundo programa). V é compatível com Vim, mas adiciona um implícito <esc>ao final do programa, portanto não preciso me preocupar com isso aqui.

Simplesmente envolve a string entre aspas usando &D, o que é equivalente ao MATL do MATLABmat2str , uma função especificamente criada para criar algo que, quando evald, fornecerá a matriz original (ou, nesse caso, string).

Cenoura , 1 byte

Como funciona

# //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

Uma alternativa, também com 1 byte, é:

$

Isso funciona da mesma forma que o acima, mas apenas leva a primeira linha de entrada. Vendo como entrada só será possível, [A-Za-z0-9]isso é bom.
