Generating HTML from python

[Philippe C. Martin]

Hi,

I wish to use an easy way to generate reports from wxPython and feel
wxHtmlEasyPrint ing could be a good solution.

I now need to generate the HTML wxHtmlEasyPrint ing can print: I need to have
a title followed by lines of text that do not look too ugly. If possible I
would like to use an existing module.

Q1) Is there such a module ?
Q2) Is my approach fairly good ?

Regards,

Philippe

As others have noted, if you need any computation at all, it is easier
to write directly in python.

I came to python from perl, where I used CGI.pm. To get that effect,
I wrote my own CGIpm.py and used it for a while.
http://www.seanet.com/~hgg9140/comp/index.html

But (at the suggestion of others in this newsgroup), I then tried
writing directly. The net effect is trivial html generation, with all
the power of python at your fingertips.

Note:
To save even more time, I made a CGI template that includes this main:

#============== ==============
if __name__=="__ma in__":
mystart()
#cgi.print_envi ron_usage()
#cgi.print_envi ron()
form = cgi.FieldStorag e()
try:
if len(form)==0:
send_form1()
else:
form_name=form['form_name'].value
if form_name=='for m1':
recv_form1()
except StandardError, e:
print "\n<BR>ERRO R: %s\n" % e
myend()

To support a stateless world:

1. Each form has a send_xyz and recv_xyz function. The end of each
recv_xyz decides what send_xyz to do next.

2. mystart and myend handle opening and closing the http and html.
They also handle state save/restore as needed (pickle or database).

I wrote soem code similar to the example above, to generate a page..
It worked out fine.

However, I want to add HTML ouput to many of my other python programs,
and I don't want to re-write this for each program. So some higher
level of abastraction is needed, but I don't know how just yet.

HTMLGen is no longer maintained, so I don't know what the best choice
is.

If you want an alternative to HTMLGen that is still maintained, you
might want to try XIST (http://www.livinglogic.de/Python/xist)

A few simple examples can be found here:

PS: Just wanted to add that HTMLGen works very well and outputs html that
wxHtmlEasyPrint ing and my email client have not problem reading (I output
student grades, missing assignments, ... in tables).

The one gitch is they do not have any installation program (that I've seen)
for windows.

Philippe

There is one huge problem with wxHtml and consequently wxHtmlEasyPrint ing. It
doesn't understand stylesheets in any way. There are many packages that
generate HTML, but they all expect a lot of the styling to be handled by
CSS. It is also a lot easier to write that way.

I would absolutely love a piece of code that could take CSS and HTML and
apply the CSS to the HTML to get the right appearance, but without any
CSS left. For example it would turn CSS formatting for class/div/span
into HTML attributes, as well as overal formatting instructions.

I did do something similar for BitPim but it requires the HTML to be perfect
and the CSS is actually a Python data structure expressing the attributes and
how they get applied. I'd love to replace it with something better.

But ultimately it does work.

How to do this really depends on what your data looks like, and how you
get it. E.g. if you just want uniform pages with paragraphs of plain
texts with headings in between, you can just make a template HTML file
with the main block of text replaced with %s, and then do something like:

text = []

for heading, paragraph in data_source:
text.append('<h 2>%s</h2>' % heading)
text.append(par agraph)

templ = open('template. html').read()
print templ % '\n'.join(text)
If your data has more structure, you might find a tool like Fredrik
Lundh's elementtree useful.
