Hi All
In experiments converting legacy code to use srfi-9 records, I'm finding
the latter doesn't travel well across modules.
See simple code below -- m1.scm runs fine however m2.scm borks when
creating srfi-9 record object
Any clue why srfi-9 can't be exported?
For various reasons I must keep (load "module.scm") mechanism
----m1.scm follows----
(use-modules (srfi srfi-9))
(define-record-type <person>
(make-person name age)
person?
(name person-name set-person-name!)
(age person-age set-person-age!))
(define <pet> (make-record-type "pet" '(name age)))
(define make-pet (record-constructor <pet>))
(define pet? (record-predicate <pet>))
(define pet-name (record-accessor <pet> 'name))
(define pet-age (record-accessor <pet> 'age))
(define set-pet-name! (record-modifier <pet> 'name))
(define set-pet-age! (record-modifier <pet> 'age))
(export make-person)
(export make-pet)
(display "pet ")
(let ((pet2 (make-pet "milou" 7)))
(display (pet-name pet2)))
(display ", person ")
(let ((person2 (make-person "james" 54)))
(display (person-name person2)))
(newline)
----m2.scm follows----
(load "m1.scm")
(display "in m2:")
(newline)
(display "pet ")
(let ((pet2 (make-pet "milou" 7)))
(display (pet-name pet2)))
(display ", person ")
(let ((person2 (make-person "james" 54)))
(display (person-name person2)))
(newline)
--------------------------------
$guile m1.scm runs successfully
pet milou, person james
$guile m2.scm first runs m1.scm but fails to recognise the srfi-9
make-person exists:
pet milou, person james
