You'll probably get more replies on Discourse. A short answer is to mention 
Rhombus and to recommend looking at all the #langs on the package server 
and in the docs.

[racket-users] Re: how could I obtain more context to isolate the problem?

[D. Ben Knoble]

Are you passing the `?` to `raco setup`? If so, I suspect your shell is 
expanding that to a file or directory named `t` (which matches the glob 
`?`), which is then used as a collection name.

Ah, I'm now seeing that with-quasi implicitly #`s the body; I believe with 
syntax-parse, #:with, and #' + template vars + #` when needed you might be 
ok.

I would also highly recommend syntax-parse and it's various abstractions.

Re: [racket-users] Equivalent of exec

Hi Norman,

With 8.0+/CS, even without make I've had a good experience. As you
say, setup or make makes things even faster, though.

If you weren't already aware, using #lang racket/base has a faster
startup-time than #lang racket, though you have to (require) things
not provided by the smaller base language.

On a slightly unrelated note, if this for consumption by anyone other than 
just you, I would use (getenv "EDITOR") (or VISUAL, if you prefer) rather 
than hard-code the path to vi.

Best,

That would be good to add to the docs in my opinion.

Could we add require? I can think of two compelling reasons:

1. What else is available in the program form? All of racket, or just 
racket/base? And either way, what if I want to use procedures from other 
packages?
2. What if I want to write a bunch of library code, and expose some of it 
in a CLI script? I do this now in different ways: a module+ main that uses 
code defined in the enclosing module, or a script that requires auxiliary 
modules. Often the "body" of the program form isn't more than a call to a 
"main" procedure: this enables me to provide that procedure as part of the 
library, too.

Re: [racket-users] Could Racket be used as a "frontend" for a non-Racket language?

[D. Ben Knoble]

No idea if this is what you're looking for, but I have a feeling it 
wouldn't be terribly difficult to design a #lang where modules were 
programs that, when run, output C# code (kind of like how scribble & pollen 
can output HTML). Then you could have a language (w/ or w/o) macros that 
gets run down to C# and let the C# compiler and project toolchain take care 
of the rest? Essentially it's only a syntax—the semantics is "turn it into 
this C# code."

[racket-users] Racket Slack archive update: privacy concerns

[D. Ben Knoble]

Update on the project to host an archive of the Racket Slack: I have been
directed to some privacy issues with the current proof-of-concept. Until 
these
issues are resolved, I have made the repository private and taken down the 
site.

If you have a copy of the archive files or site, I must ask that you refrain
from using them publicly until those impacted have a chance to decide what 
to
do.

If you wish to participate in the discussion, please join the Racket Slack 
[1,2]
and use the channel #slack-archive. You can also reach out privately to me 
and
Sam Tobin-Hochstadt, as we have become the organizers behind the archive. So
that I remain accountable and transparent, I would prefer any private
communication with me to include Sam.

The crux of the issue is data privacy: What data is in the archive? What 
are we
doing with private data? How are we using data from the archive? How are we
going to explain that to people? What will opt-in/opt-out look like?  
More
details in Slack.

Great idea, thanks.

Yeah, this is one of my top priorities. I’m thinking I’ll break it down by 
date. But I may want to rewrite the static generation in Racket first (to get 
it off Ruby + Jekyll, which may be unfamiliar to the community).


> Again, I think it’s great that you’re doing this!

Thanks :)

[racket-users] Racket Slack archive [help wanted]

[D. Ben Knoble]

In case you missed it/aren't on Slack:

The latest version of the Slack archive is up-and-running at 
https://benknoble.github.io/racket-slack-archive/ (extends through roughly 
2021-06-07).

The site is now built using a mix of 
- Racket (data processing, mostly the json, hash, and unzip modules)
- Jekyll/Ruby (site-generation; a plugin makes pages out of all the channel 
directories, which are then rendered via a set of HTML templates)

I have some todos to make a nicer experience, and help is welcome. Also if 
anyone wants to start working porting the Jekyll + Ruby stuff to Racket, 
feel free.
