Re: problems rendering kanren-sourceforge.scm using PLT SSAX/SXML distro

Hello!

	Alas I cannot comment on the PLT distribution. I can however
tell how kanren-sourceforge.html was generated from the corresponding
.scm file. It was with the help of the following simple GNU Makefile

---begin-make
# Directory where all the "included" modules are located
LIB=../SSAX/lib

# Converter function. We are using Bigloo at present. It's one long line
CONV=bigloo -i -s -I $(LIB) -eval "(module html (include \"myenv-bigloo.scm\") (include \"srfi-13-local.scm\") (include \"util.scm\") (include \"SXML-tree-trans.scm\") (include \"SXML-to-HTML.scm\") (include \"SXML-to-HTML-ext.scm\"))"

# Convert SXML to HTML
%.html: %.scm
	$(CONV) $*.scm > $@

---end-make

LIB points to a directory that is a local copy of the SSAX/lib
directory from the CVS repository. The (module help ...) declaration
enumerates all Scheme files that are loaded from the LIB directory
first. After that, the file in question, e.g., kanren-sourceforge.scm
is loaded and the result is written into
kanren-sourceforge.html. Despite the need to load a bunch of files in
an interpreter, the whole process is quite fast. I could just as well
used SCM or Petite Chez or Gambit: the only change is in the prelude
file myenv-*.scm, and a different module declaration (alas, almost
each Scheme system has its own module system). Gauche Scheme supports
SXML more natively, so fewer files need to be loaded.

Regarding the file try.scm: from what I know, I don't think that any
of "ssax.ss", "stx-engine.ss", "stx-xsl.ss", and *path* are really
needed. PLT experts are in a better position to comment.

Regarding performance: I use SXML-to-HTML conversion in a production
environment. For example, you can try the following (non-production)
server:
	http://www.metnet.navy.mil/cgi-bin/oleg/server/grids/
	http://www.metnet.navy.mil/cgi-bin/oleg/server/imagery/
In both cases the queries are quite complex and involve joins and
other frills. The SXML generation and the conversion to XML is done on
the fly. BTW, for various reasons, three different computers (not
counting the firewalls) are engaged in answering your request.

	Cheers,
	Oleg
