I am trying to set up racket-stories to run on my local machine, but it is not clear how to do that. What is the process exactly? This seems like a could potential addition to the README.

You are right, it ought to be in the readme.

In the terminal:

racket server.rkt

Or open "server.rkt" in DrRacket/emacs and run it.

I had indeed tried that, but I get an error:

The application raised an exception with the message:

Is there something special I have to do for the sqlite stuff to work?

Screenshot of error:

RacketError

I'm quite a newbie in Racket, so I apologize in advance if I'm missing something obvious.

Hi Jens,

I created the directory and tried again. Now I get a new error (progress!):

New Error

Hi Alex,

I cloned a new version of racket-stories to see what was wrong.
The database setup now creates the folder dbs if is is missing
and at the same time made a small change to create-tables.

To setup the database, open "model.rkt".
Run it.
Then enter (create-tables) in the repl.

Now the database is setup, and you can start the web server in the terminal.

Thanks!

So I can run the site now, but when I try to create a user, this happens:

UserCreateError

It appears that the error is referencing the following function in model.rkt:

(define (create-user username password email)
  (unless (good-username? username)
    (raise (exn:fail:user:bad (bad-username-reason username)
                              (current-continuation-marks))))

Thanks for helping me with this by the way. I'm so close to having it working!

I'm on Ubuntu. I have no clue - perhaps there's a way for me to change the keysize to something my system supports. I'll look into it and get back.

Hi Alex,
Did you succeed in getting it up and running?

With a fresh checkout, I can't get it to run, the error is related to secret.rkt trying to decrypt a badly formed UTF-8 string:

No key in either environment or home. Using default.
. . secret.rkt:49:2: bytes->string/utf-8: string is not a well-formed UTF-8 encoding
  string: #"\255\3\311\371\244M\376\213T\261\263\a/\2128B\30\32\305f\v]\346\201\233_.\347\323l[\377%\3!\341"

Also, the instructions are missing the fact that you need to install postmark-client.

soegaard commented Mar 4, 2020

The snippet around "secret.rkt:42:2" is:

; aes-decrypt : string -> string
(define (aes-decrypt crypto-text)
  (bytes->string/utf-8
   (aes-decrypt-bytes crypto-text)))

Here (aes-decrypt-bytes crypto-text) attempts to decrypt one of the encrypted keys in the code.
Since your machine doesn't know the correct key, the output of aes-decrypt-bytes is not the
original key. Given the original key the result will be byte string containing an utf-8 encoded string - and
the call to bytes->string/utf-8 will succeed.

I suggest replacing the original encrypted keys in "secret.rkt" with your keys.
Use aes-encrypt in the repl to produce som encrypted keys and copy-paste them
to replace keys in the code.

I'll need to add a note on postmark-client. It's used to send emails to people (for password reset).

Are there dependencies outside of the standard racket distribution?

Yes, you'll need to install crypto:

raco pkg install crypto

Was able to get it running after running raco pkg install --auto gregor crypto deta postmark-client urlang, now I just need to figure out keys :)
