Re: [racket-users] Racket v7.9
But wait! There’s more! (Or, more prosaically: I left out several bullet items.) * The `datum` form from `syntax/datum` works with syntax pattern variables and `syntax-parse` attributes. * Unicode input works with recent versions of libedit in addition to libreadline. On Mac OS, a compatible version of libedit is included with Racket.

[racket-users] Racket v7.9
Racket version 7.9 is now available from https://racket-lang.org/ * Racket CS may become the default Racket implementation in the next release.

[racket-users] Regarding collections and racket versions...
All of my programming code is in a single collection: ~/.plt-scheme/4.2.1/collects/ even when I have installed newer versions of Racket. The 'raco setup' function updated all my program bytecodes throughout my system. I do go through some confusion regarding collections when I install a newer version of racket because I believe it makes use of a newer default collection and if I remember correctly, I make a change somewhere so that the system looks to my original collection location instead. I appreciate any comments or advice regarding collections in general, or my use of the single collection directory: ~/.plt-scheme/4.2.1/collects/ :) -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Is there a function to find and update all compiled directories?
Thanks for all the wonderful feedback! The 'raco setup' function worked beautifully for me resolving my issues. Running raco setup without arguments did bring my system to it's knees, i.e., slowing it down to a snail's pace but after a reboot all seems to be well. Based on the displayed feedback, I saw that it did a lot of work. Would there be less work for 'raco setup' if I uninstalled all but the current and previous versions of Racket?

Re: [racket-users] Advice for beginner
Thanks John for your answer, and sorry for not answering for so long... I've been occupied by other things, and I've had to postpone my "learn Racket" ambitions a bit... Anyway, time for a fresh start... Am 08.09.2020 um 22:08 schrieb John Clements: Can you be more specific? Are there particular programs that you can point to? I think the solution to your problem is going to depend a bit on the kind of slowdowns that you’re seeing. I was just referring to how long it takes in DrRacket to evaluate an apparently simple program. Something like ``` (+ 1 1) ``` It takes about 3-4 seconds to run that. Simply adding a the #lang declaration makes the whole thing much faster... ``` #lang racket (+ 1 1) ``` Actually, it looks really similar to the problems described here ( https://stackoverflow.com/questions/37508535/excruciatingly-slow-over-ten-seconds-for-1-1-with-language-how-to-des) and here (https://github.com/racket/drracket/issues/281).
