is there anything else on syntax-parse besides: http://docs.racket-lang.org/syntax/index.html?

I would like to see something more hands on like, how to implement struct using syntax-parse.

there’s http://docs.racket-lang.org/syntax-parse-example/index.html

here’s a macro that implements structs as lists https://groups.google.com/d/msg/racket-users/ss20lwfUhjs/F_-RU_qQAQAJ

Thanks, that’s very helpful. I actually looked at the code for struct in the racket repo but it hasn’t been ported to syntax-parse yet.

struct can’t use syntax/parse because syntax/parse’s implementation uses struct

any idea what module-path-index-resolve: "self" index has no resolution is about? i see various references to it online but no conclusive answers.

It means that you have a module path index where module-path-index-split returns two #fs. It doesn’t stand for any particular module, but it used to mean “this module” within a module.

@jjwiseman ^

is it a symptom of an error in my code? i don’t think i’m doing anything fancy with modules…

i changed a #lang errortrace racket to #lang racket and no longer get that error. but that can’t be the root cause.

It might be a problem with #lang errortrace. Do you have a small-ish program you can send me?

@mflatt i don’t, sorry.
