Currently, my `lang/reader.rkt` file uses #lang s-exp syntax/module-reader:
#lang s-exp syntax/module-reader
hypothetical-lang
#:read read
#:read-syntax read-syntax
#:info make-info
(define (make-info key default use-default)
(case key
[(drracket:toolbar-buttons)
(list (dynamic-require 'hypothetical-lang/button 'button))]
[else (use-default key default)]))
Is the `get-info` function you described the same as the `make-info` that
is currently in my code? I'm pretty confused on how to write a `get-info`
function and where it would go. How can I go about setting this up?
If you have any other style suggestions about how to change this button, I
would appreciate them.
