[racket-users] custom input ports and specials

I'm implementing a tokenizer as a custom input port using `make-input-port`. My thinking is that `peek-char-or-special` and `read-char-or-special` will be the primary interface to the tokenizer; port locations will also be used. In this case, the input port should emitting characters as well

One clicks on your Twitch and the first thing coming from the speakers is "Do you remember Jack? Jack Firth?" Everyone does, of course ;-) On 12. 04. 21 17:31, Stephen Foster wrote: > In the CodeSpells project, we are using Racket + Unreal Engine.  This > combo would be my recommendation for

Re: [racket-users] Polished 3D package for some simulations

In the CodeSpells project, we are using Racket + Unreal Engine. This combo would be my recommendation for doing "3D stuff" and also anything with physics. As you can see from the first few seconds of this video, we are spawning in Twitch users as 3D physical objects:

[racket-users] Re: Judgement not holding

Thank you, I did just that! :D 4. Checking for membership in an environment sounds like a (very) decidable problem. It maybe simpler to just write a judgment form for the positive case, and simply defining the negative case as “when the judgment doesn’t hold”. A sexta-feira, 9 de abril de

Ok, much appreciated. For those reading, I'm pivoting to this phrasing. -- Could not connect to example.com due to an unverified certificate. You can address this by downloading the certificate from a source your operating system trusts (to mitigate man-in-the-middle attacks), then adding the

Yes, that's right. Ryan On Mon, Apr 12, 2021 at 4:23 PM Sage Gerard wrote: > Understood, thank you. By "trusted location," do you mean a server with a > certificate that operating systems already trust? > On 4/12/21 10:15 AM, Ryan Culpepper wrote: > > Racket does not provide a way to do that.

Understood, thank you. By "trusted location," do you mean a server with a certificate that operating systems already trust? On 4/12/21 10:15 AM, Ryan Culpepper wrote: > Racket does not provide a way to do that. > > You can use `openssl s_client -showcerts -connect host:port < /dev/null` to >

Re: [racket-users] How do I, a client, get a copy of an untrusted server certificate?

Racket does not provide a way to do that. You can use `openssl s_client -showcerts -connect host:port < /dev/null` to get the server's certificate chain in PEM form (with other logs around it). Of course, an attacker could intercept the connection and send you their CA certificate instead. It

[racket-users] How do I, a client, get a copy of an untrusted server certificate?

When ssl-connect fails due to an untrusted certificate, this error is raised: ssl-connect: connect failed (error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed) I'd like to give the user a more helpful error, like this: Could not connect due to an untrusted

[racket-users] Wheel / touchpad / trackpoint accuracy/speed scrolling fix for DrRacket

I started a new thread as the original topic no longer matched. I installed 8.1.0.2 x64 CS and enabled logging in gen-wheels. Matt was right: wheel-steps-mode is indeed set to 'integer while gen-wheels runs in DrRacket's editor. The only two changes required to get smooth/accurate scrolling
