I have no relationship with them other than asking about Racket support

Can anyone help with this ?


The "jupyter run" command seems to just send the entire contents of the 
file to the kernel to evaluate. Not just the code parts, the entire JSON 
document. So the Racket kernel reads the JSON document as an 
S-expression (!), tries to evaluate it, and errors because of a comma 
(unquote in Racket) outside of quasiquote.


(Wow.)

I've found other people having similar problems:


https://stackoverflow.com/questions/56039870/how-to-use-jupyter-run-to-call-a-jupyter-notebook-on-local 
(and other question linked from comment)


On the other hand, the docs for "jupyter-run", such as I've found, seem 
to suggest that you're supposed to be able to run them on notebooks, not 
plain source files.


  https://pythonhosted.org/jupyter_runner/

So I'm confused.

In any case, to test whether the Racket kernel is working, I would 
suggest either "jupyter notebook 
/PATH/TO/iracket/examples/getting-started.ipynb" or "jupyter console 
--kernel=racket" and try evaluating some things interactively.

[racket-users] Racket Jupyter/nextJournal

[tbrooke]

There has been some discussion about Racket on Jupyter. nextJournal is a 
fairly new project for hosted notebooks that is written in Clojure and has 
support for Clojure as well as several other languages. In addition to 
Clojure they have templates for Julia,  Haskell, and Scala and they support 
Bash which should allow for installation of almost anything including 
Racket. They do have a free level and some paid levels. 

I have no relationship with them other than asking about Racket support
