[Zope-dev] Building custom DTML tags and accessing _.something

2001-05-09 Thread Morten W. Petersen 

Hia guys,

I was wondering if any of you could give me a couple of hints about how to
make the _.{random,string,range,Datetime} thingies from a tag expression.

I.e. instead of doing this:

dtml-widget select options=[1,2,3,4,5,6,7,8,9,10,11,12,13]
selected=[1,3,5,7,9,11,13

This could be done:

dtml-widget select options=_.range(1,14,1)
selected=_.range(1,14,2)

Like this (with the DTML var tag):

dtml-var [1,2,3,4,5,6,7,8,9,10]

dtml-var _.range(1,11)

Thanks  cheers,

Morten

Look as one of the *_expr parameters in e.g.
Products.MIMETools.MIMETag.

They do what you want and you can see, how it is implemented.
