can Velocity set a default value for a variable when no value found in VelocityContext?

Question

Velocity just print the tag name if no value was found in VelocityContext, ie, $name in my template file, but there is no value for \"name\" in VelocityContext, so just \"$n

Answer 1

Not easily for all variables as far as I see, I only managed to do it for some variables specifically as follows:

Template:

#if ( !$somevar )
#set ( $somevar = "mycontent" )
#end

Var is: $somevar

Result:

Var is: mycontent
