Here's a simple gunit test for a portion of my grammar which generates a flat list of nodes:
objectOption walks objectOption: <<one:"value">> -> (one "value") In the above, I purposefully left out the caret (i.e. ^(one "value)) since it's a flat list of nodes and not a tree. Another option which seems intuitive is to leave off the parenthesis, like this: objectOption walks objectOption: <<one:"value">> -> one "value" In the first case the parenthesis cause an error 1 failures found: test2 (objectOption walks objectOption, line17) - expected: (one \"value\") actual: one \"value\" And in the second case I get an exception: line 17:20 no viable alternative at input 'one' line 17:24 missing ':' at 'value' line 0:-1 no viable alternative at input '<EOF>' java.lang.NullPointerException at org.antlr.gunit.OutputTest.getExpected(OutputTest.java:65) at org.antlr.gunit.gUnitExecutor.executeTests(gUnitExecutor.java:245) ... What is the correct way to match a flat tree?
