Question

When using StringTemplate 4.0.2 the following object construction:

ST st = new ST("@myToken@", '@', '@');

produces the exception:

1:8: '@' came as a complete surprise to me
Exception in thread "main" org.stringtemplate.v4.compiler.STException

    at org.stringtemplate.v4.ST.<init>(ST.java:142)
    at org.stringtemplate.v4.ST.<init>(ST.java:136)

Is there some special way to use the ‘@’ character as a custom delimiter or is it simply not allowed?

Answer 1

@ is used for defining regions and is a reserved operator.
