Details:
Currently there is some (imo) inconsistency in [inset_tag] when in key
"variable" is given an empty one. While for lot of tags this will lead to
(again imo) expected "do nothing behavior", in some tags like [object] or
[modify_unit] will lead to error messages for not defined keys. To solve this
issue, I created a macro, but I think would be nice become default behavior:
"inset tag if varible length greater than 0"
#define INSERT_IF_EXIST TAG VARIABLE
[if]
[variable]
name={VARIABLE}.length
greater_than=0
[/variable]
[then]
[insert_tag]
name={TAG}
variable={VARIABLE}
[/insert_tag]
[/then]
[/if]
#enddef
