Step 8: Changing the selected output

In the previous step, you found invocations of the macros we are interested in. Modify your query to find the top-level expressions these macro invocations expand to.

Note: An expression is a source code element that can have a value at runtime. Invoking a macro can bring various source code elements into scope, including expressions.

⌨️ Activity: Find the expressions that correspond to macro invocations

As before, if you don't know how a piece of source code is represented in the library, you can use the auto-completion and contextual help to discover the classes and predicates you need.

1. Edit the file 8_macro_expressions.ql with the previous query
2. Use the getExpr() predicate in the select section, to return the wanted expressions.
3. Once you're happy with the results, submit your solution.
