I tried my euler install last night, and it's lightning
fast, but it doesn't have all the built-ins I need.
In particular, I added support for fn:resolve-uri
and fn:tokenize from XQuery to cwm this week.
It is pretty straightforward to write builtins in euler.yap
http://eulersharp.sourceforge.net/2006/02swap/euler.yap
but I should study your builtins a little more..
I haven't made much progress yet with some of those builtins..
fn:resolve-uri corresponds to url_info_relative/3 in the pillow library.
I can almost see how to add it myself, but I moved to my laptop
and I haven't recreated the http/REST setup and I'm
having trouble figuring out how to test euler.yap outside the http/REST
setup.
fn:tokenize is like re.split() in python... I see a regular expression
module in yap, but no split predicate. I guess it can be implemented
in terms of matching... hmm... actually, I need re.search(), not
re.match(), and I don't see that in yap.

I was not sure about list:member, but implemented it as inverse of
list:in
yes, i think that's right.
Anyhow, to test builtins, I use a growing bunch of test cases in
http://www.agfa.com/w3c/euler/testbuiltins.n3
giving proof output
http://eulersharp.sourceforge.net/2006/02swap/testbE.n3
Do you have a way of testing offline? do you use a proxy cache
or something? I was trying to work on a plane.
