RE: checking for defined and exists in a template

I think Brett already answered this.

 

if (defined $x->{y}):

    [% IF x.y.defined %]

if (exists $x->{y}):

    [% IF x.exists(y) %]

Hmmm (reading the manual), maybe this would work.

 

[% IF x.$y %]

 

[% IF x.$y == 'foo' %]

Maybe I should restate. What is the perl template toolkit directive equivalent of:

 

if (defined $x->{y})

 

-- or --

 

if (exists $x->{y})

 

Thanks.

or

 

[% IF x == 'foo' %]

 

Combining constructs would be redundant.

Suppose I want to do an include only if something is defined,

how do I do it?

 

[% IF x.defined and x eq "foo" %]

    [% INCLUDE myfile %]

[% END %]

 

something like that? can't seem to locate it in the

man pages.

 

Thanks.
