Can you write a Perl program to replace the content of anything found inside double-quotes with the result of piping it to the command `fmt`?

  Easily, though you don't need to drag external programs like fmt into it - perl comes with a standard module for word wrapping. Text::Balanced (for extracting the quoted text) and Text::Wrap would be the core of such a program. https://perldoc.perl.org/Text::Balanced https://perldoc.perl.org/Text::Balanced https://perldoc.perl.org/Text::Wrap https://perldoc.perl.org/Text::Wrap

    Could you write it for me as a one-liner? I’d like to learn more Perl and this would help.

      Oh, I wouldn't try to squeeze it down into a one liner. Maybe for a simple definition of the quoted text that doesn't need to account for edge cases like escaped quotes inside...

        Just a normal program then? No edge cases needed
