I'm inferring that your #lang probably uses a non s-expression syntax. If your #lang has a non-s-expression syntax, then you will need to need either use the 'language-info syntax property with or use a configure-runtime submodule. The first method is introduced here, and it's the one I've used before https://docs.racket-lang.org/guide/module-runtime-config.html <https://docs.racket-lang.org/guide/module-runtime-config.html> But either way, you would want to override the current-read or the current-readtable parameter to use your new reader. How are you implementing your reader? Are you using syntax/module-reader, or are you providing the read, read-syntax, and get-info functions directly? If you're providing them directly, are you generating them using a function like make-meta-reader, are you using a readtable, are you using a parser library, or something else? > Pretty sure I've seen this work with Redex, so I *think* it's possible! > > Thanks in advance for any help! > Chris -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
