Subject: Another scheme/dsssl question From: Norman Walsh <norm@xxxxxxxxxxxxx> Date: Mon, 29 Dec 1997 13:47:34 -0500 |
Is it possible to test for the existance of a definition? Suppose I want to make it possible for a derived stylesheet to override a value. I'd like to write something like this: (define default-foo '("x" "y" "z")) ... (if (some-predicate? foo) foo default-foo) Is that possible? --norm DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
