[Zope-dev] RFE: Make PythonScripts.standard available from DTML _.standard

2001-01-05 Thread Steve Alexander 

This is an RFE for Zope 2.3.

I'm posting it here for discussion, rather than in the Collector.


In the new PythonScripts product (that is a standard part of Zope 2.3) 
there is a standard utility module that can be imported into a Python 
Script with

   import Products.PythonScripts.standard

or

   from Products.PythonScripts.standard import *

It contains useful functions such as those for text formatting 
(html_quote, url_quote_plus, and so on). It also contains the DTML class 
for creating temporary chunks of restricted DTML.

These functions would be really useful as part of the DTML _ namespace 
variable. I sometimes find myself wanting to use html_quote in a DTML 
expression. I'd also be able to use these functions from ZPatterns 
SkinScript.

The PythonScripts product could add these functions to the _ namespace 
variable at product init time, so there would be no need to change the 
DocumentTemplate modules.

And here's a patch:
Just add these lines at the end of
   lib/python/Products/PythonScripts/standard.py

from DocumentTemplate.DT_Util import d
import standard
d['standard']=standard
del standard

Of course, you could add similar lines to PythonScripts/__init__.py, or 
in a completely new "enable python scripts standard module with dtml" 
product.

 If you have something like that, wouldn't it be better, more readable,
 etc, for it to be moved intop a python script, even if that script was
 only 1 line long?
 
 eg:
 dtml-if
 "mysomething(_['title_or_id'],_.standard.html_quote(absolute_url()+_[id]))"

You are being deliberately Byzantine there!

Not to mention that _['title_or_id'] is equivalent to just title_or_id.

However, I agree with you in principle.
I've had other, much simpler, cases where I want to html_quote just a 
part of something. I can't put my finger on an example right now, so 
that does weaken my case a little :-)

I provided a good example for my case, don't know what Byzantine means,
erk :-S

I like your idea.

It is one way to implement my recent "lobbying" request
with minimal effort.
