Ruby regex: ignore las comillas si hay dos puntos delante de ellos

Question

Estoy tratando de escribir una expresión regular de Ruby que capture frases citadas además de las que tienen ":" justo antes de ellas. Por ejemplo:

Obama: "¡Sí, podemos!"

Debe ser ignorado.

escribí algunas pruebas:

Answer 1

EDIT: Sin embargo, más ajustes.

Dependiendo precisamente lo que se ve la entrada como, esto funciona para ASCII:

(?<! [:\s]) \s* (["']) (?: (?! \1) .)+ \1 

para “ 'coincidencia' Unicode comillas”, que tiene que ser un poco más en sus parejas, tal vez junto estas líneas:

(?xs) (?<!:) \s+ 
    (?: (["']) (?: (?! \1) .)+ \1 
    | “ .*? ” # English etc 
    | ‘ .*? ’ 
    | « .*? » # French, Spanish, Italian 
    | ‹ .*? › 
    | „ .*? “ # German, Icelandic, Romanian 
    | ‚ .*? ‘ 
    | „ .?* ” # Hungarian 
    | ” .?* ” # Swedish 
    | ’ .?* ’  
    | » .?* « # Danish, Hungarian 
    | › .*? ‹ 
    | 「 .*? 」 # Japanese, Chinese 
    | 『 .?* 』 
)

Aquí es un programa de prueba en Perl, pero los principios deben sostener perfectamente en Ruby:

#!/usr/bin/perl 
use strict; 
use warnings; 
use utf8; 
use open qw[ :std IO :utf8 ]; 
while (<DATA>) { 
    print if/(?<! [:\s]) \s* (["']) (?: (?! \1) .)+ \1/sx; 
} 
__END__ 
"Take off, hoser!"

Dorothy Parker:"Brevity is the soul of lingerie." 
Dorothy Parker: "Brevity is the soul of lingerie." 
Dorothy Parker: "Brevity is the soul of lingerie."

Larry Wall said: “I don't know if it's what you want, but it’s what you get. :-)” 
Larry Wall said: “I don't know if it's what you want, but it’s what you get. :-)” 
Larry Wall said, “I don't know if it's what you want, but it's what you get. :-)” 
Boss: And what's that "goto" doing there?!? 
Hacker: Er, I guess my finger slipped when I was typing "getservbyport"...

'I wish I had never come here, and I don't want to see no more magic,' he said, and fell silent. 
src/perl/mg.c: "I wish I had never come here, and I don't want to see no more magic," he said, and fell silent. 
src/perl/mg.c: 'I wish I had never come here, and I don't want to see no more magic,' he said, and fell silent. 
src/perl/mg.c => "I wish I had never come here, and I don't want to see no more magic,' he said, and fell silent." 
‘I wish I had never come here, and I don’t want to see no more magic,’ he said, and fell silent.’ 
“I wish I had never come here, and I don’t want to see no more magic,’ he said, and fell silent.” 

La salida es

"Take off, hoser!"

Eso probablemente se ve “mal”, pero es debido a la cotizaciones internas Aquí está una versión más completa, que ilustra mejor los temas:

#!/usr/bin/perl 
use strict; 
use warnings; 
use utf8; 
use open qw[ :std IO :utf8 ]; 
while (<DATA>) { 
    chomp;  
    my $bingo = m{ 
     (?<! [:\s]) \s* 
     (?: (?<=^) 
      | (?<= \s) 
     ) 
     (?: (["']) (?: (?! \1) .)+ \1 
      | “ .*? ” # English etc 
      | ‘ .*? ’ 
     ) 
    }sx; 

    if ($bingo) { 
     printf("Line %2d, quote 「%s」\n", $., $&); 
     printf(" " x 7 . "in line 『%s』\n", $_); 
    } else { 
     printf("Line %2d IGNORE 『%s』\n", $., $_); 
    }  
}  
__END__

Además, hay una propiedad derivada Unicode estándar llamado \p{Quotation_Mark} o \p{QMark} para abreviar, pero Rubí doesn' t apoyarlo. Es posible enumerar todos éstos cabo utilizando the unichars script:
