----------------------------------------
Summary: Detect when a variable is unknown in StringSubstitutor
Key: TEXT-127
URL: https://issues.apache.org/jira/browse/TEXT-127
Project: Commons Text
Issue Type: Improvement
Reporter: Jean-Baptiste REICH
Currently, StringSubstitutor is not replacing a variable that is unknown. It
would be nice to define the behavior in this case and to allow raising an
exception.
A workaround is to define a custom StringLookup that raises an exception when
the variable is unknown but this prevent from using the default value feature
from StringSubstitutor
