FWIW, I make a /Applications/Racket symlink to the current installation and add
that to my path, because I know that something somewhere is not going to grok
the space in that directory name...

Re: [racket-users] macOS Post-Install

A better strategy may be to add

 /etc/paths.d/racket

as a file that contains the path to your Racket installation. For
example, the path to put in that file is

 /Applications/Racket v6.11/bin

if you've installed the current release into the "Applications" folder.

[racket-users] macOS Post-Install

[Jeremiah Peschka]

I’ve installed Racket 6.11 from the dmg file supplied on the website. However, 
I’ve had to link binaries into /usr/local/bin one by one as I find something 
that I’m missing.

Is there documentation of which binaries to link into /usr/local/bin ?

Re: [racket-users] Open source projects

[Neil Van Dyke]

I consider myself pretty community-oriented, but, if I'm trying some new 
platform, and the recommended practice when I am confused by the 
documentation is to go file documentation bug reports, then I'm unlikely 
to follow that advice.


I know that posting a bug report is an interruption to any work, and to 
my initial enthusiasm and immersion, and the suggestion sounds 
potentially dismissive, and not immediately helpful to me.  Now I don't 
have any good-sounding advice for what to do.


However, if the recommended practice is to ask in the active canonical 
forum, that sounds like a worthwhile idea, from myuser's perspective.  
(In addition to being a good idea from the community perspective, as I 
suggested in my previous message.)

[racket-users] trending racket repos on github

['John Clements' via Racket Users]

Thanks to Andreas Per Olsson’s post on the Racket Facebook group, I found out 
about this link

https://github.com/trending/racket?since=monthly

which lists the Racket repos that are “trending”. I think this has something to 
do with the number of stars it has. Anyhow… interesting information.

Re: [racket-users] Open source projects

One other relatively easy project would be to add sha256 to the
openssl library.  https://docs.racket-lang.org/openssl/index.html

There is a version of sha256 implemented in
https://github.com/RayRacine/grommet but it's for Typed Racket only.
I know that it's possible to use TR from untyped code, but it would be
nice to have it all in one place.

No, but collecting ideas that might be useful in UI design can be

WHile Racket is much better documented than most free software, it 
could be improved.  Debugging documentation requires a supply of 
ignorance, which is repidly used up as documentation testers 
learn what the documentation means.  So when you find the 
documentation obscure, treat it as a documentation bug and report it.  
Maybe, when you become an expert and your supply of ignorance has run 
out, you can even propose patches to improve that documentation!
