[Zope] Syntax

[Paul Zwarts]

Hi Benoit,

AFAIK, the _ is used as a hack.

_ actually is the namespace variable, but in this case:

  REQUEST['var']   and    _[REQUEST['var']]

is no different. You use the _['something'] construction when a dash is used
in the name:

<dtml-var sequence-item> works by itself. If you want an expression of that:

<dtml-var "sequence-item-5"> does not work because it syubtracts item from
sequence and five from item. Instead use:

<dtml-var "_['sequence-item']-5">

It is a hack where _['a-b'] forces a-b transalated by zope as a_b so there
is not expression problem.

Did I miss anything, oh great zopemasters?


Cheers,
Paz

Hi,

Do you know the difference between
  REQUEST['var']   and    _[REQUEST['var']]  ?

And also can you explain me what is this :  _

Thanks
