Hi,
I desperately need to write a generic method that binds to a hash-table.
I have noticed that native scheme types like pair, list, and vector are
automagically recognised in GOOPS as <pair>, <list>, and <vector>.
Even SRFI-19 dates are recognised as <date>.
How did you spot those classes?
I read the guile vm and module source code :)
How then to add similar goodness so that I can write:
(define-method (enumerate! (o <hash-table>) env)
...
)
A quick investigation using ‘class-of’ and the various constructors:
scheme@(guile-user)> (class-of (make-hash-table))
$1 = #<<class> <hashtable> 9f96780>
scheme@(guile-user)> (use-modules (srfi srfi-69))
scheme@(guile-user)> (class-of (make-hash-table))
$2 = #<<class> <srfi-69:hash-table> a115000>
Regards
Ok, so you have confirmed that you can merrily make my enumerate! method ?
I still fail to.
Cheers
Brent
