Before: 4
After: 8
Example 1
{def name=ns1 $var1='ns1 org value'} {def name=ns2 $var1='ns2 org value'} Original values: <br/> $ns1:var1 : {$ns1:var1} <br/> $ns1:ns2:var1 : {$ns1:ns2:var1} <br/> ... {set name=ns1 scope=root var1='new value'} {set var1='new value'} ... New values: <br /> $ns1:var1 : {$ns1:var1}<br/> $ns1:ns2:var1 : {$ns1:ns2:var1}<br/>
The following output will be produced:
Original values:
$ns1:var1 : ns1 org value

In the manual for {def} it is stated that def does not support the 'name' and 'scope' parameters. In the examples of {set} however, it does. Did you simply 'search and replace' all occurences of {let} in the documentation, or do some parts of the manual need an update?

Namespaces are supported by the set function but not by the def statement as mentionned in the documentation.
In other words, you can define a variable and set a value for a specific namespace.

{def name=ns1 $var1='ns1 org value'}
{def name=ns2 $var1='ns2 org value'}
There still ist a name=.. in there.

The following does not work:
In this case $root:loaded outputs nothing!

How to define global variables
Monday 04 September 2006 12:30:09 pm

You cannot declare a variable as global, so just declare it like a regular variable (definition is compulsory):
{def $total_items=0}
To define or set a global variable:
{set scope='global' $total_items=0}
To read a global variable:
{$#total_items}
To update a global variable, you naturally combine the above:
{set scope='global' $total_items=$#total_items|inc()}

It really logical, but I had to try a few times before it got to me:
You need to declare the variable in pagelayout.tpl to access it in templates on same or higher level than the one that sets it.

either? what if undefined?

And more importantly, what if variable is previously undeclared?

set limitations

You can't {set} array values or object attributes.
Eg: {set $object_parameters['link_to_image']=true()}
is *not* valid (at least in 3.6.2). Bummer.

however, you can achieve something similar with array_merge :
