Especially if the equation numbers are links to the equations. For PDF's we'd need to have pdf links, and a pdf reader that understands a back button. -- hendrik -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Can raco distribute produce a single executable?

It seems the default behavior is to compile a statically linked executable. For whatever reason, the distributed Windows compile seems to be done using shared libraries instead. I haven't used Racket on Windows, so I can't say for sure. I'm planning to install it on my windows partition when I boot into it next time. I'll let you know if for some reason it is statically linked (although I highly doubt it). -- Ethan Estrada -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

I will explore its use in the context of equation numbering, and after that, it would be great to participate in a team for the creation of a public and documented version. This particular capability of Scribble [numbering equations], would increase very much its usability for mathematical writings (e.g. lecture notes), and I'm looking forward for the evolution of Scribble in that direction. Thanks again, and congratulations for all your fine work and beautiful documents. Sincerely, EC. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Redefine how Racket prints
You can change `print` for a specific port with `port-print-handler`. There's also the `global-port-print-handler` parameter, but setting that changes `print` only for ports that uses the default printer. The blue-versus-purple distinction in DrRacket is built into the output port that DrRacket supplies a `current-output-port`. That port has a print handler that works with the destination editor to show `print` output in blue, while other output to the port is shown in purple. I don't think it's possible to change the way `print` works and still have it in blue, but others (especially Robby) might know otherwise, At Mon, 6 Mar 2017 20:48:17 -0800 (PST), Vasily Rybakov wrote: > I want to change how Racket prints some values both in REPL and when using > (print), (println), e.t.c. > > Suppose that I want change like this (gives as simple example): > > (define (print~ datum [out (current-output-port)] [quote-depth 0]) > (if (number? datum) > (print `',datum out 1) > (print datum out quote-depth))) > > So Racket will print all numbers with preceeding quote. > This definition is in separate file and is exported like this: > > (provide (rename-out [print~ print])) > > So in other files it is seen as (print) function. > > Problems/questions: > > 1.
