See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
SetParser is capable of returning the exact variable and value
of a "SET X=Y" statement, in the cases where X is of a specific
set of variables; currently "SQL_MODE" and "@MAXSCALE...".
The actual value of the SET statement also needs to be parsed in
the case of SQL_MODE, but it becomes unnecessary convoluted if that
information somehow should conditionally be expressable in a return
value.
So, the value will be parsed separately.
