Hi,
@Tobias :
Well my "real life" template is a it complicated but it's easy to make an
experiment.
Suppose the template you want to use is : <<somevariable>><<now>>
{{!!title}}
In a test template you can try 3 ways of writing the template :
\define myFilter() foobar$(somevariable)$ +[removesuffix[foobar]]
First expression :
<<somevariable>><<now>> {{!!title}}
Second expression :
<$set name="somevariable1" filter=<<somevariable>> value=<<somevariable>>
emptyValue="Default value">
<<sometext1>><<now>> {{!!title}}
</$set>
Third expression :
<$set name="somevariable1" filter=<<myFilter>> value="Default value"
emptyValue=<<somevariable>>>
<<sometext1>><<now>> {{!!title}}
</$set>
@Andreas :
You're right : the filter design is the point. I came to the same
conclusion and that's why I've been using this strange filter.
But it's twisted and I was wondering if there was a simpler way to specify
a default value.
Thanks to both of you !
FrD
