Hi! I found here docs: https://docs.racket-lang.org/routy/ I'd like to try this for fast prototyping, but can't find the package as my google-fu is sloppy I guess. Any help please, sirs and madams?

[racket-users] Re: Complete Word (Ctrl+/)
@Glenn Hoetker: First, create a file with rkt ending with the following content: #lang s-exp framework/keybinding-lang (text:get-completions/manuals false) (keybinding "c:TAB" (λ (editor event) (send editor auto-complete))) ; i changed this to control+tab, its more convenient for me. (keybinding "c:l" (λ (editor event) (send editor insert "λ"))) then, in Dr. Racket in the Menu: Edit -> Keybindings you can add this file. @Robby Findler: Thank you! (text:get-completions/manuals false) in my keymap file did it. Now it takes a little bit longer to start (those 2-3 seconds), but that is expected by me. Thank you very very much! Am Mittwoch, 12.

[racket-users] Complete Word (Ctrl+/)
Hi! I like DrRacket very much, because it's hassle-free. I like fast startup times, that's why I disabled all tools in the preferences, because at the moment I don't use them. Further more, it's easier for me to map "Complete Word" to the tabulator key. I do not use the emacs keybindings. I have in the preferences, tab "Editing", subtab "General Editing" "Enable keybindings in menus" checked. It's more convenient for me. For that purpose I did a custom keybinding which I successfully enabled in DrRacket: #lang s-exp framework/keybinding-lang (keybinding "TAB" (λ (editor event) (send editor auto-complete))) (keybinding "c:l" (λ (editor event) (send editor insert "λ"))) That all works very well, DrRacket starts very fast, and editing is also fast enough. The λ is also very helpful for me because I don't have an english keyboard. There is only one thing I would like to change: If I invoke the auto-complete method, the first time I'm using it it takes some time (2-3 seconds maybe?) until the complete suggestions are appearing. After the first time using it its fast enough. I think it's loading on demand. Finally my question: Is there any way to tell DrRacket to load that required data on startup? I know, why bother about it, but 2 seconds are 2 seconds. Thank you for your suggestions. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

[racket-users] Not a rant at all!
Hi! I just wanted to say that the whole racket system (including dr. racket) is by far my most liked programming system I've ever tried. I'm a hobby programmer and the glitchless ide combined with the very huge documentation makes me wonder why I'm not using it since ever ;) Sometimes I'm in trouble to understand some concepts, but it gets better with every small project I'm doing. Thank you for this awesome package! Gregor -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

I like the idea of having a helper to convert to strings, thats great! Also, I didn't know about flatten, thats really interesting! Basically my problem description was only the endpoint of what I wanted to archieve. I'm using Racket right now happily to search through a sqlite database for personal learning. For this I'm using query-rows from db. This returns a list of vectors. At first I printed the results with a function that takes the vectors and transformed them into a human readable information, because I knowed how to iterate over a list, transform vectors and how to use the repl. With your, and the other David's (sorry, could not resist!) help I'm able to put that onto a webapp what I will try next - after I managed to memorize und truly understanding that concepts. With those naive approach (playing with data) I'm learning quite good how all fits together. You two really helped me to understand how it's meant to be used! Thank you!

[racket-users] Iterate over a list to construct a single string?
Hi!
I'm very new to Racket and the lisp family generally, and very slowly starting
to get an idea how everything works together.
Now my very first question ;)
If I have a list of string's, how can i recursivly iterate over that list and
compose a single string out of the elements of that list?
I prepared a simple example, so hopefully you can understand what I'm talking
about:
(define mylist '("hello" "darkness" "my" "old" "fiend"))
(for-each (lambda (elem)
(displayln elem)
)
mylist)
It prints out every element of mylist as I expect in a new line.
But what if I want to collect all strings into one single string, so that I can
get "hellodarknessmyoldfriend"?
I think I can use string-append, right?
But how could I do that? Is there a idiomatic way to do that in Racket?
Thank you very much for every input.
Gregor
