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