Take a look at `define-record-printer`
(http://api.call-cc.org/doc/chicken/special-forms/define-record-printer), e.g.

 (define-record-printer matrix
   (lambda (m port)
 (fprintf port #matrix ~ax~a (matrix-rows m) (matrix-cols m

[Chicken-users] Changing string representation for records

2013-09-22 Thread Chris Mueller 

Hi,

i've currently a generell question about string representation/output 
for records within the

chicken interpreter.

Assume:

(define-record matrix rows cols data)

#;1 (make-matrix 2 1 (f64vector 1 2))
#matrix

Is there any possibility to specify the string output for this record 
instance?


This would be great :)

Chris
