Therefore, it would be useful if Scribble expressions were not syntactically limited to the form @ ‹cmd› [ ‹datum›* ] { ‹text-body› }, and instead allowed text-mode and racket-mode arguments to be freely & indefinitely sequenced.<div> <br></div><div>What I've found using Scribble is that many of the functions one writes are, of course, intended to operate on a text argument. So the text-mode argument naturally wants to come first in the function:</div> <div><br></div><div>@cross-ref{This text}</div><div><br></div><div>Now, suppose I want to add an optional second argument. The natural place for this optional argument would be after the first:</div> <div><br></div><div>@cross-ref{This text}["where.html"] </div><div><br></div><div>or</div><div><br></div><div>@cross-ref{This text){where.html}<br></div><div><br></div> <div>But AFAIK, Scribble forbids these patterns. So I might try this:</div><div><br></div><div>@cross-ref["where.html"]{This text}</div><div><br></div><div>But that doesn't work either, because the cross-ref function expects the target text to be in the first position. So either I must forego idiomatic Scribble expressions altogether:</div> <div><br></div><div>@(cross-ref "This text" "where.html") </div><div><br></div><div>Or use a keyword argument:</div><div><br></div><div>@cross-ref[#:destination "where.html"]{This text}</div> <div><br></div><div>As a workaround, that's OK. But at this point, Scribble is reaching up into my code and starting to impose design restrictions (namely, keyword arguments) that have ripple effects elsewhere.</div> </div> <br></div></div>____________________<br> Racket Users list:<br> <a href="http://lists.racket-lang.org/users" target="_blank">http://lists.racket-lang.org/users</a><br> <br></blockquote></div><br></div> </blockquote></div><br></div></div></div></div> <br>____________________<br> Racket Users list:<br> <a href="http://lists.racket-lang.org/users" target="_blank">http://lists.racket-lang.org/users</a><br> <br></blockquote></div><br></div>
