Hi IF,
I think this is what you want. You were right about the issue -- you were
consing onto the history list but then immediately throwing away the result
because it wasn't modifying the original history value.

You can use the value-contract function, along with contract-stronger? to
do this.

Thank you!
I can get the code that follows to run, but the chatbot never replies. I
surmise this is because lists are not mutable.
With the background I have the most obvious way forward would be to use an
array instead of a list, but that does not strike me as the best approach
to take while try
I have some macros that generate functions. For testing purposes, I'd like
to be able to ask the function "Do you have this contract ?" Is
there a way to do that? I've been digging through the Contracts section
and googled for it but I'm not seeing one.

Hi,
Presumably you are using 'head' to get the first element of a list.
However, there is no function 'head' for lists.
see: https://docs.racket-lang.org/reference/pairs.html
Try using 'first' and 'rest' instead of 'head' and 'tail'.

Hi everyone,
After trying to implement some changes Sage suggested (all errors are my
own), I am now encountering the following message (courtesy of DrRacket):
"head: unbound identifier in: head"
Could someone help me find a fix?
As before, I welcome suggestions on how to better do this the fu
Yeah, I've been meaning to integrate those parts of that library into Redex
proper but just haven't found the time.
Also, I've thought it would be nice if Redex were able to look at the
context of a particular, say, "or" or "then" expression and figure out if
it needed parens. Sadly, for now you h
I suppose another option would be to use one combined field with an email
format like this:

"search-terms" might need some special attention though. You might be able to
list two author terms, like this:
"author:tonygarnockjo...@gmail.com" : true,

I was just thinking along the lines of adding a "name" field to the table with
the user/login data. If it is set, then it is displayed instead of the email.
You should be able to search by this field too of course.

Thanks Ryan!
There's all sorts of nice goodies in that library, like
current-atomic-rewriters and friends.

The `binary-rw` function from unstable/gui/redex library has some support
for optionally parenthesizing its arguments.

Hello all,
I'm working on coding up a little language model in Redex, and I'd like to
get it to render things in the form that my colleagues are used to. This
means some infix operators as well as dealing with parenthesizing based on
operator precedence.
Here's a boiled-down sample of what I'm up
No, but it's an interesting thought. It might be quite a lot of design work
to come up with something that made sense, but would you like to sketch out
a proposal here to make the idea a little more concrete? I can't promise
anything, but it'd be good to know the kinds of requirements that might
