|11:30||[832dae9274] I guess these changes warrant another year on the (c) line. (user: jesper tags: trunk)|
|11:30||[50a6cdb35a] Use newly added make-chain-pred in constructing version comparisors (user: jesper tags: trunk)|
|11:27||[e839f3b951] Add procedure make-chain-pred, which makes procedures taking any number of arguments and compares them two-and-two, in the order given, with a supplied predicate. For example: (define string-or-number= (make-chain-pred (lambda (a b) (= (if (string? a) (string->number a) a) (if (string? b) (string->number b) b))))) (string-or-number= "50" 50 "000050.00") will now evaluate to #t.
