Hey - just remembered asking here. Will anyone be in ELS (https://european-lisp-symposium.org/2020/index.html) this year? If so, I will be there as well so we could have a chat over a coffee. :slightly_smiling_face:

I’m wondering what controls the printing of a vector. I have a long list of vectors from a DB query: (list (vector 6 2611 65548 "DE" 544 "Yellow" "Immediate" (dt "2020-01-13 22:17:00" #f) (dt "2020-01-14 22:17:00" #f) "Continue") ...)

But I would like to see something more like:

(list (vector 6 2611 65548 "DE" 544 "Yellow" "Immediate" (dt "2020-01-13 22:17:00" #f) (dt "2020-01-14 22:17:00" #f) "Continue") ...)

Is is possible to do that?

Try pretty-print with a large column size.

I should mention I’m in racket-mode in Emacs, that may be part of it.

Thanks! I’ll try that.

Not sure whether the output in racket-mode is controlled by Racket or racket-mode.

This variable in racket-mode is interesting: > racket-pretty-print > Use pretty-print instead of print in REPL.

But even though racket-mode uses print as default - there is no guarantee that the default parameters are set to the same as in the repl. We need to check the code (I have been bothered by the same issue in the past).

@gknauth you could put the data into a table: https://docs.racket-lang.org/rebellion/Tables.html\|https://docs.racket-lang.org/rebellion/Tables.html

Trace from DrRacket is as follows:

I do not know what exactly this clarifies, if anything. What else can I provide?
