[REBOL] Re: if and parens

From: joel:neely:fedex at: 5-Oct-2002 20:10

Hi, Laurent, Infix (operators) has higher precedence than prefix (function evaluation), so the expression if get in info? to-file elt 'type = 'file [print elt] is actually treated by REBOL in the same order as if parenthesized as if get (in (info? (to-file elt)) ('type = 'file)) [print elt] that is, the IN is applied to the INFO? object, but the second argument is the LOGICAL! value FALSE, which, as the error message stated, is not a WORD! value. Since you just want to exclude subdirectories from the list of contents of the current directory, you could write foreach elt read %. [if not dir? elt [print elt]] instead. -jn- Laurent Giroud wrote:
