[REBOL] Expanding Rebol's definition of a word

From: AJMartin::orcon::net::nz at: 24-Dec-2003 22:43

I've found that it's possible to expand the definition of a Rebol word (but
not actually Rebol itself because I don't have the source). Here's my C#
code using regular expressions to parse out get-word!, set-word!, word! and
get-set-word! values.

    String Separators = @"\s\[\]\(\)";
    public class Get_Set_Word : Value {
        public Get_Set_Word () {
            Title = "Get-Set-Word";
            Pattern = new Regex (@"\G:[^" + Separators + "]*:" + Delimiter);
            }
        }
    public class Get_Word : Value {
        public Get_Word () {
            Title = "Get-Word";
            Pattern = new Regex (@"\G:[^" + Separators + "]*" + Delimiter);
            }
        }
    public class Set_Word : Value {
        public Set_Word () {
            Title = "Set-Word";
            Pattern = new Regex (@"\G[^" + Separators + "]:*" + Delimiter);
            }
        }
    public class Word : Value {
        public Word () {
            Title = "Word";
            Pattern = new Regex (@"\G[^" + Separators + "]*" + Delimiter);
            }
        }

In my tests so far, I can get my R# to recognise these as get-word, set-word
and word values:

 C# F# & ^ * = == && ++ ~ >: <: !: :~ ~#
 Word :GetWord SetWord:

As well as email, issues, pairs, tags, tuples, dollars (money!), files,
urls, degree-minutes-seconds (12°34'56"), strings ("test"), percentages
(99.5%), scalar-like values (60Km/H).

I'd really like it if these definitions became a part of Rebol.
