[racket-users] difference in struct printing from default #:transparent versus make-constructor-style-printer

I'm seeing some bad behavior from make-constructor-style-printer when there are lists mixed in with the structs. It seems to switch from print mode to write mode when going under a list. Whereas the default printer for transparent structs gets this right. The following program demonstrates the d

[racket-users] Re: Pretty Printing for ASTs represented as structs

Thanks for the tip! I found the following to work pretty well :) #lang racket (require racket/match) (require racket/struct) (struct Var (name) #:methods gen:custom-write [(define (write-proc ast port mode) (match ast [(Var x) (write x port)]))]) (struct Num (value)
