[mod_python] feature request: psp templating returns html code to calling script, not to browser.

Regarding my feature request below, I've hacked together a small piece
of code to retrieve the raw python source, and the html result of that
source. This code is heavily inspired by the PSP class of psp.py script
from mod_python.
It works for me, does not support forms and sessions (it is meant to
produce html formatted e-mail bodies), does not support Windows (path
names there use backslashes), and maybe more limitations.

Maybe the developers are interested in adding (something like) this to
the psp.py file?

get_source produces the python source code, get_html compiles the psp
input file to html code.


from mod_python import _psp

import os
import sys

def get_source(filename):
    dir, fname = os.path.split(filename)
    dir += "/"
    pycode = _psp.parse(fname, dir).splitlines()
    pycode = [s.rstrip() for s in pycode]
    for line in pycode:
        left = line.replace("\t", " "*4)
        result += left+"\n"
    return result

def get_html(filename, vars={}):
    code = get_source(filename)
    lines = code.splitlines()
    code = 'html = ""\n'
    for l in lines:
        l = l.replace("req.write(", "html +=").replace(",0)", "")
        code += l+"\n"
    global_scope = globals().copy()
    html = ""
    l = locals()
        exec code in global_scope, l
        et, ev, etb = sys.exc_info()
        raise et, ev, etb
    return l["html"]
