I'm following the example from "F*dging up a Racket" at
https://www.hashcollision.org/brainfudge/index.html
I set up a project within ~/.racket/6.12/collects:
.
├── bf
│ ├── hello2.rkt
│ ├── hello.rkt
│ ├── lang
│ │ └── reader.rkt
│ ├── language.rkt
│ ├── parser.rkt
│
OK. I had a partial success. reader.rkt needs to start with something like:
#lang s-exp syntax/module-reader
"language.rkt"
#:read my-read
#:read-syntax my-read-syntax
...
except that I can't run my BF program (hello2.rkt) from an arbitrary
directory, because it doesn't know where to locate lang
Change the first few lines of lang/reader.rkt to:
#lang s-exp syntax/module-reader
bf/language
#:read my-read
#:read-syntax my-read-syntax
;; ...
And just install the entire directory as a package using raco pkg
install. This could take a while. If you want to make it faster, just
skip building t

Thanks. I am building a language with the same syntax as typed racket,
with the plan to (1) run the input as a typed racket program to type
check, and then (2) run it using my implementation, ideally with the
possibility of querying for the inferred types of the variables and
functions in the inpu
I don't think so, but check `typed-racket/types/type-table`:

Edit: I'm not even sure how to do (1) without (2) given that it requires
multiple evaluations of the same input. Any pointers would be appreciated.

Typed Racket first runs the macro expander, and then type checks the
expanded program.
If your implementation can type check an expanded program too, then
you can probably get started by copy/pasting typed racket's
#%module-begin and inserting a new pass over the program just after
the optimizer.
