I’m sorry - I didn’t explain what kind of highlighting we’re looking for.
We’re building a new #lang, and we want it so that sometimes when you run,
DrRacket highlights a part of the program you are running. But we only want
that in certain situations, so we want to create a function which we
Hello,
I am glad to announce typed-compose, a small package defining some
utilities for composing functions in Typed Racket:
https://pkgd.racket-lang.org/pkgn/package/typed-compose
Typed Racket's compose only takes two arguments, because in general it is
difficult to specify that the return
If you just want to silence the error with a blunt instrument, then you could
try a parameterization where sandbox-path-permissions is set to:
(append (map (λ (p) `(exists ,p)) (filesystem-root-list)
(sandbox-path-permissions)))
This suffices since it is an existential check, not a file
Heads up: My earlier example was missing a closing paren. Also just saw that
your subject line asked "Why", so I checked.
openssl/mzssl provides a parameter called `ssl-default-verify-sources'. See
[1]. The parameter is created during module instantiation with a OS-dependent
default value.
Thanks for the explanation.
I can't figure out why scribble/manual needs openssl, but oh well.
After reading through openssl, I've gone with a slightly less blunt instrument:

I don't know if Scribble needs OpenSSL, but a dependency probably does. The
only precondition of that error is that openssl/mzssl appears *somewhere* among
the dependencies. I run into that same error for evaluators that have nothing
to do with Scribble.

Ah! I didn’t know about the module browser, thanks! And I guess this chain
makes sense.

Complicated systems are surprising! Somehow each little step wasn't
completely crazy and yet there must be a lesson in here
somewhere. :)

I think a good first question here is "what do you want to happen when you
are running the program from outside DrRacket?". DrRacket is, in a general
sense, designed to reflect extra information about how a program runs when
it can glean that information, but it isn't meant to be the only way that
I have a sandbox that loads scribble/manual (indirectly) to render some HTML.
But it crashes with the following error:
> racket -e "(require racket/sandbox)" -e "((make-evaluator 'racket/base)

file-exists?: `exists' access denied for /etc/ssl/cert.pem
If you open a file that requires scribble/manual with the module browser
(available via the Racket menu item in DrRacket), you'll see that ssl is
needed by the code that opens urls (presumably to do https) which is needed
by the code that handles planet requires (since planet requires may involve
