This is the change to DrRacket: https://github.com/racket/drracket/commit/edfea2c649d4d1cfdc2c9facf4dbdb4663be0a07 (you'll want the subsequent commit too, tho). I believe this fixes a bug in DrRacket but the way these handlers are set up is pretty complicated. Here's an example program that

The lack of newlines is probably because of a bug that I pushed a fix for. Maybe try a shapshot build? https://pre.racket-lang.org/installers/ Robby On Wed, Aug 10, 2016 at 7:34 AM, Delphine Demange wrote: > >> Yes, DrRacket's "constructor" mode does this. This code

Re: [racket-users] racket command-line REPL: Constructor style printing mode?

Hi, Just for the sake of completeness. In constructor-style-print.rkt, I've switched on the printing of booleans as "true" and "false" as follows (editing line 14): ;; print-convert/constructor-style : Any -> Any (define (print-convert/constructor-style v) (parameterize

Re: [racket-users] racket command-line REPL: Constructor style printing mode?

Thanks for the prompt reply! I managed to install the package. For my current use-case, using the racket in module mode, with the right #lang directive at the top of the .rkt file is enough. For the interactive mode, however, I was expecting something like racket -I 'constructor-style-print

One option is to use Alex Knauth's package quote-bad. https://docs.racket-lang.org/quote-bad/index.html?q=constructor#%28part._.Changing_the_printing_style_to_avoid_printing_bad_uses_of_quote%29 If you want to see how he sets the print handler:

[racket-users] racket command-line REPL: Constructor style printing mode?

Hi, I'd like to use the Constructor printing style in the command-line REPL, so that it behaves the same as in my current DrRacket config, e.g. > (list 1 2 3) (list 1 2 3) Using https://docs.racket-lang.org/reference/printing.html, I've been trying to set (interactively) the right parameters
