Re: Clearsilver with CherryPy

Although I haven't used CherryPy, there is nothing to prevent you from
using ClearSilver without the CGI trappings.

You definitely don't need to have all of your HDF data in HDF files.
Sometimes there is static data, and the HDF files make that easy.

If you aren't using the CGI wrappings in neo_cgi, you can do something
like:

# You still need to load neo_cgi, because the other two modules are
# fakes actually located in neo_cgi, a probably poor design decision
import neo_cgi, neo_cs, neo_util

hdf = neo_util.HDF()
cs = neo_cs.CS(hdf)
cs.parseFile(template_file)
cs.render()

As for getting data into the HDF, there is hdf.setValue(k,v) which
takes strings for key and value.

It shouldn't be hard to write functions that convert various python
datatypes into hdf, ie for a dictionary:

for (k, v) in dict.items():
  hdf.setValue("%s.%s" % (prefix, k), v)

or for a list:

for x in range(length(array)):
  hdf.setValue("%s.%d" % (prefix, x), array[x])

There's also a simple ORM in the codebase in python/examples/base called
odb, with a row object in hdfhelp.py which exports rows from a database
by making them into a prefix.colname=value format.
