I'd like to use some schemey way of doing this. s-expression -> HTML perhaps.
What is the thinking guile-user's way of approaching this?
There are several good tools out there for doing this: Oleg Kiselyov
has written a Scheme-based port of SAX called SSAX  that can read
and emit S-expressions in a format he calls SXML. It's available for
Guile as part of Andy Wingo's guile-lib . For permissive HTML
parsing, Neil Van Dyke has written HtmlPrag . And if you're
interested in a more DOM-based approach, I've got a module called SDOM
Hope that helps!
Thank you and others for replying to my query.
I looked at  and  in your list - I didn't want to parse XML - not
Trying  I found that Oleg made me jump through hoops with his
web pages. That put me off a bit. When I tried his code, it was not
clear to me where the output
was going. So I tried . I ended up using  because I like reading
Andy Wingo's blog and
it just worked out of the box anyway.
It was such fun! I've not quasiquoted so deeply before. I'm still
tinkering with the script - I use
it to see how my hetrogeneous overnight builds got on.
(Incidentally, the FC3 build seems to fail because guile-gtk-2.1 fails
to build (it fails in make, not
configure. Is guile-gtk-2.1 supposed to work on gtk+-2.4? ... not
completely the right place to
ask, I guess).
I have a question about the output. How do I put line breaks into the
generated text? All on one
line is fine for my browser - but makes it hard to eyeball the HTML.
After I wrote it (and saw how concise the sxml translator was), I though
"so what's all the fuss
about PHP?" One of the major things, perhaps, is the generation of
images in-line. So I thought
"couldn't guile+sxml do something similar making SVGs on the fly?" Is
that being quietly coded
up by someone? Making a few graphs on the fly shouldn't be so hard,
should it? In fact, I was
even thinking of doing it myself :)
