Mientras escribía mi ensayo para Shakespeare, me di cuenta de que necesitaba acortar mis referencias de citas a longitudes más manejables. Anteriormente había estado escribiendo esto:

(Act 1, Scene 2, Lines 345-346)

Pero ahora me han dicho que los escriba así:

(I.ii.345-6)

Claramente, necesito un código de golf para jugar un poco mis referencias de citas de Shakespeare.

La tarea

Escriba un programa o función que, dada una entrada de cadena que sigue a la Plantilla 1 o 2, imprima o devuelva una cadena que siga a la Plantilla 3 o 4, respectivamente. Solo tiene que admitir los actos 1 a 5 y las escenas 1 a 9.

Plantillas

Plantilla 1

(Act x, Scene y, Lines a-b)

Puede suponer que xnunca excede 5, ynunca excede 9, ay bsiempre son enteros positivos que no exceden el valor entero positivo máximo de su idioma, y asiempre es exclusivamente menor que b.

Plantilla 2

(Act x, Scene y, Line a)

Las mismas condiciones que la Plantilla 1, excluyendo información sobre b.

Plantilla 3

(x.y.a-b)

Donde xes un número romano en mayúscula, yes un número romano en minúscula ay bson números, y bse acorta a solo los dígitos menores que el primer dígito diferente de igual importancia a.

Plantilla 4

(x.y.a)

Las mismas condiciones que la Plantilla 3, excluyendo información sobre b.

Casos de prueba

Deje f(s)ser la función definida en la Tarea. ""denota un valor de cadena.

>>> f("(Act 1, Scene 2, Lines 345-346)")
"(I.ii.345-6)"

>>> f("(Act 3, Scene 4, Lines 34-349)")
"(III.iv.34-349)"

>>> f("(Act 5, Scene 9, Lines 123-234)")
"(V.ix.123-234)"

>>> f("(Act 3, Scene 4, Line 72)")
"(III.iv.72)"

"(II.iii.123-33)"

>>> f("(Act 4, Scene 8, Lines 124-133)")
"(IV.viii.124-33)"

Para los propósitos de este desafío, se deben admitir las siguientes traducciones de números arábigos a romanos:

1 i     I
2 ii    II
3 iii   III
4 iv    IV
5 v     V
6 vi    (you do not have to support past 5)
7 vii
8 viii
9 ix

El lenguaje de programación de Shakespeare (no competidor)

Realmente me gustó esta pregunta, y como había algún interés en una respuesta en lenguaje Shakespeare, aquí hay una.

A Tale of Two Cites (sic).

Julius Caesar, the first citizen of the Roman Republic.
Brutus, a traitor -- member of the Fifth Column.
Cicero, the greatest Roman orator.
Cleopatra, a proud queen, whom the Romans want to make one of their own.
Romeo, a man who's sometimes there.
Juliet, a maiden who can follow Romeo or stand on her own.


           Act I: Imperium Romanum.


           Scene I: Cleopatra puts men in their place.

[Enter Cleopatra and Julius Caesar]

Julius Caesar:
    Thou art as lovely as the sum of an amazing delicious gentle blossoming warm angel and a charming noble reddest rose.
    Speak your mind. Open your mind. Open your mind. Open your mind! Open your mind!

Cleopatra:
    You are as stuffed as the sum of a hard old green horse and the sum of a grandmother and
    a normal tiny bottomless furry small purple roman.

[Exit Julius Caesar]
[Enter Brutus]

Cleopatra:
    You are as sorry as the difference between a rich morning and a leech.
    You are as smelly as the difference between yourself and a sunny rural blue bold uncle.
    You are as vile as the difference between Julius Caesar and yourself.

[Exit Brutus]
[Enter Cicero]

Cleopatra:
    You are as half-witted as the difference between Brutus and the bluest death.


           Scene II: How do you solve a problem like Cleopatra?

[Exeunt]
[Enter Cleopatra and Julius Caesar]

Julius Caesar:
    Listen to your heart!

[Exit Cleopatra]
[Enter Brutus]

Julius Caesar:
    Is Cleopatra more pretty than a fair charming noble angel?

Brutus:
    If so, we must proceed to Scene IV. Is Cleopatra not worse than the sweetest small aunt?

Julius Caesar:
    If so, let us proceed to Scene III.

Brutus:
    Speak your mind.

Julius Caesar:
    Is Cleopatra nicer than the moon?

Brutus:
    If so, speak your mind.

Julius Caesar:
    Is Cleopatra better than a golden King?

Brutus:
    If so, speak your mind.

Julius Caesar:
    We shall proceed to Scene V.


          Scene III: Brutus and his friends.
Julius Caesar:
    Is Cleopatra as fair as the blossoming smooth sky?

Brutus:
    If so, speak your mind!

Julius Caesar:
    Speak your mind!

Julius Caesar:
    Is Cleopatra jollier than the sum of a yellow sweet road and a summer's day?

Brutus:
    If so, speak your mind!

Julius Caesar:
    Is Cleopatra friendlier than the sum of a sweet large angel and a white cow?

Brutus:
    If so, speak your mind!

Julius Caesar:
    Is Cleopatra as furry as a rich handsome huge mistletoe?

Brutus:
    If so, speak your mind!

Julius Caesar:
    We shall proceed to Scene V.


          Scene IV: Cicero is asked to speak.
[Exit Brutus]
[Enter Cicero]

Julius Caesar:
    Is Cleopatra as beautiful as the sum of a small furry white angel and a summer's day?

Cicero:
    If so, speak your mind!

Julius Caesar:
    Speak YOUR mind!


          Scene V: A period piece -- Cleopatra's reprisal.
[Exeunt]
[Enter Cleopatra and Julius Caesar]

Julius Caesar:
    You are as beautiful as the sum of a embroidered sweetest sunny delicious trustworthy Lord
    and a reddest charming mighty honest King.
    You are as healthy as the difference between yourself and a embroidered Lord. Speak your mind!
    Open your mind! Open your mind! Open your mind! Open your mind! Open your mind! Open your mind!

Cleopatra:
    Are you jollier than the sum of a little rural white bottomless blue blue sky and a rural furry white green old morning?

Julius Caesar:
    If so, we must proceed to Act II. Open your mind! Open your mind!

Cleopatra:
    You are as damned as the difference between yourself and a half-witted dusty snotty rotten oozing death.

[Exit Julius Caesar]
[Enter Brutus]

Cleopatra:
    You are as rotten as the difference between yourself and a rural rotten bottomless evil miserable famine.

[Exit Brutus]
[Enter Cicero]

Cleopatra:
    You are as fatherless as the difference between Brutus and a normal pig. Let us return to Scene II.



          Act II: Lovers' arithmetick.

          Scene I: Our lovers discuss what they have in common.

[Exeunt]
[Enter Romeo and Juliet]

Romeo:
    Thou art as bold as a curse. Listen to your heart!

Juliet:
    Am I better than nothing? If so, let us proceed to Scene III.

Romeo:
    Open your mind. Open your mind.

Juliet:
    Listen to your heart! Open your heart!

Romeo:
    Thou art as amazing as the product of the difference between a handsome white proud white grandfather and an aunt
    and the sum of a loving niece and the Heaven. Speak your mind! Open your mind.
    Listen to your heart. Is the quotient between yourself and the sum of the sum of
    a noble noble mighty blossoming embroidered good father
    and a gentle large large normal old joy and an old happy squirrel as yellow as the quotient between
    myself and the sum of the sum of a pretty beautiful yellow green bold charming kingdom and
    a beautiful blue normal cute large nephew and a pretty big cousin?

Juliet:
    If not, we shall proceed to Scene II.

Romeo:
    You are as sweet as the remainder of the quotient between yourself and the sum of the sum of
    a blossoming bottomless golden peaceful noble healthy nose and
    a happy honest sunny green healthy hero and a hard blue fellow.

Juliet:
    YOU are as sweet as the remainder of the quotient between yourself and the sum of the sum of
    a blossoming bottomless golden peaceful noble healthy nose and
    a happy honest sunny green healthy hero and a hard blue fellow.


          Scene II: Tense times.
Juliet:
    Is the quotient between yourself and the sum of a good beautiful delicious grandmother
    and a noble wind as amazing as the quotient between myself and the sum of
    a smooth furry embroidered roman and a honest sister?

Romeo:
    If so, you are as amazing as the remainder of the quotient between
    yourself and the sum of a cute healthy smooth kingdom and a normal mother.


          Scene III: Parting is such sweet sorrow.
Romeo:
    Open your heart! You are as noble as the sum of a honest charming smooth peaceful fine rose and the sum of
    a cute amazing trustworthy summer's day and an angel. Speak your mind!

(Tiene más de 6000 bytes de longitud). Hay algunos trucos allí, pero no he intentado jugar mucho al golf porque: (1) ya contribuí mi parte del golf en otra respuesta y (2) cambié todos los caracteres a "Página "y" Puck ", o todas las frases para" big big big big big cat ", parecen estropear la diversión. En cambio, para la parte que trata con números romanos, he usado caracteres que son romanos, etc. Reutilicé caracteres e instrucciones para guardar algo de mecanografía. :-)

El programa debería ser en su mayoría directo, pero una arruga que vale la pena mencionar es que cuando escribí esto asumí que leer un número entero funcionaría de la siguiente manera scanf: (1) consumir solo tantos caracteres de la entrada como corresponda a un número entero, y (2) en caso de que de falla, deje la variable sin cambios. (Usé esta segunda propiedad para distinguir entre la Plantilla 1 y 2 en el Acto II, leyendo hasta "Línea" e intentando leer un número entero.) Desafortunadamente, resulta que (lo que considero) es un error en la implementación original de el lenguaje en el que leer un número entero consume todo hasta el final de la línea y arroja un error si falla, por lo que necesita un parchelibspl.c para que se int_inputcomporte más scanf.

Y con eso, funciona:

% spl2c < good.spl > good.c
% gcc -lspl -o good good.c                                    
% for f in in-*; do cat $f; echo "->"; ./good < $f; echo "\n"; done    
(Act 1, Scene 2, Lines 345-346)
->
(I.ii.345-6)

(Act 3, Scene 4, Lines 34-349)
->
(III.iv.34-349)

(Act 5, Scene 9, Lines 123-234)
->
(V.ix.123-234)

(Act 3, Scene 4, Line 72)
->
(III.iv.72)

(Act 2, Scene 3, Lines 123-133)
->
(II.iii.123-33)

(Act 4, Scene 8, Lines 124-133)
->
(IV.viii.124-33)

Pseudocódigo de nivel ligeramente superior en el que trabajé, para ayudar a cualquiera que intente comprender:

Print `(`=40
Read 5 chars
Read Int A
Output A in Roman
Output `.`=46
Read 8 chars
Read Int S
Output S in roman
Output `.`=46
Read 6 chars
Set N to -1
Read Int N
If N ≠ -1 goto finish
Read 2 chars
Read Int M
Output Int M
Output `-`=45
Read 1 char
Read Int N
Reduce N wrt M
finish:
Output N
Print `)`=41

Relacionar lo anterior con el código final se deja como ejercicio. :-) Tenga en cuenta que ShakespearePL tiene aritmética y pilas y gotos pero no punteros (solo etiquetas), por lo que implementar "subrutinas" como la conversión a Roman es un poco ... interesante.

LaTeX, 513 364 259 226 215 178 159 Bytes

Los buenos ensayos siempre deben escribirse en LaTeX.

\documentclass{tui}\makeatletter\input{xstring}\def~#1 #2, #3 #4, #5 #6){(\@Roman#2.\@roman#4.\StrCut{#6}-\A\B\A\if\B\else-\fi\StrCompare\A\B[\P]\StrMid\B\P9)}

Esto utiliza el paquete xstring ya que no hay una gran cantidad de manejo de cadenas incorporado. En el lado positivo, el límite superior para el \Romanformato incorporado es mayor de lo que necesitaremos (incluso para los sonetos) 2^31-1. He incluido \documentclass{ecv}en el recuento, pero ninguno del código de prueba:

\begin{document}
\t(Act 1, Scene 2, Lines 345-346) 

\t(Act 3, Scene 4, Lines 34-349)

\t(Act 5, Scene 9, Lines 123-234)

\t(Act 3, Scene 4, Line 72)

\t(Act 2, Scene 3, Lines 123-133)

\t(Act 4, Scene 8, Lines 124-133)
\end{document}

(Si estuvieras lo suficientemente loco como para usar esto, tendrías que eliminar los nombres de macro al menos. Sobrescribir macros de un solo carácter es una mala práctica)

Ungolfed y comentó:

\documentclass{ecv}%We have to have a documentclass
\makeatletter %treat the @ sign as a normal character (it's used in "internal" macro names)
\input{xstring} %use the xstring package
\def\shortref#1 #2, #3 #4, #5 #6){ %macro with 6 positional arguments searated by spaces and commas 
    (%print the open bracket
    \@Roman#2 %arg 2 is the Act,  print uppercase Roman
    .%print the full stop
    \roman#4 %arg 4 is the Scene, lowercase roman
    .%print the full stop
    \StrCut{#6}{-}{\A}{\B}%split arg 6 (Lines) at the hyphen, into macros \A and \B
    \A %print the bit before the hyphen
    \ifx\B\empty%if \B has nothing in it do nothing
    \else %otherwise
        - %we need to print a hyphen
    \fi%endif
    \StrCompare{\A}{\B}[\P] %returns (in macro \P) the position at which \A and \B first differ
    \StrMid{\B}{\P}{9}%print \B starting from position \P (9 > the number of remaining characters)
)}%print the closing bracket

Tenga en cuenta que en esta versión los comentarios son obligatorios; de lo contrario, la nueva línea se interpreta como un espacio en blanco y se expande a un espacio.

Elimina los caracteres innecesarios antes de reemplazar los dos primeros números con bloques de icaracteres. Luego hace coincidir fragmentos de estos is para formar los números romanos apropiados. Luego capitalizamos el primer número romano. Finalmente, hacemos coincidir tantos números como podamos antes del guión y después del guión, de modo que el número de dígitos en el número sea el mismo. Luego eliminamos ese prefijo del segundo número.
