false var gets evaluated for skinparam, so the skinparam stopps working

Question

Could you check if this is really the intent to evaluate true/false vars (if those exist) within skinparam?

Answer 1

Well, the preprocessor is executed before any processing. So it does its job without knowing nothing about the underlying PlantUML syntax.

The skinparam line is then changed to :

skinparam shadowing <color:red>false</color>

which indeed does not remove shadowing.

So it works as designed although it could be an issue.

A possible workaround for skinparam could be to check "false" as substring instead of strict string. Would that help ?

Not sure I understood this, could you explain the workaround a bit more or give an example?

This way worked:
