Quick & dirty utilities. I use them, but I haven't tested them with enough edge cases to feel like they deserve to live outside @racket[unstable]. I welcome improvements.
Find single or double quote marks at the beginning of @racket[_tx] and wrap them in an X-expression with the tag @racket[_single-preprender] or @racket[_double-preprender], respectively. The default values are @racket['squo] and @racket['dquo].
@examples[#:eval my-eval
(wrap-hanging-quotes '(p "No quote to hang."))
(wrap-hanging-quotes '(p "“What? We need to hang quotes?”"))
]
In pro typography, quotation marks at the beginning of a line or paragraph are often shifted into the margin slightly to make them appear more optically aligned with the left edge of the text. With a reflowable layout model like HTML, you don't know where your line breaks will be.
This function will simply insert the @racket['squo] and @racket['dquo] tags, which provide hooks that let you do the actual hanging via CSS, like so (actual measurement can be refined to taste):
@verbatim{squo {margin-left: -0.25em;}
dquo {margin-left: -0.50em;}
}
Be warned: there are many edge cases this function does not handle well.

(code:comment @#,t{Argh: this edge case is not handled properly})
(wrap-hanging-quotes '(p "“" (em "What?") "We need to hang quotes?”"))
