Runtime/Compilation Arguments

For an example of forwarding arguments in a call to mason run, a chapel program built in mason might have a config const number that corresponds to a value used in MyPackage.chpl. To try out different values at runtime, pass the values for number to mason run as follows:

mason run -- --number=100
mason run -- --number=1000

Note

Previous releases allowed flags meant for the compiler or chapel program to be mixed with those meant for mason build or mason run, respectively. As of Chapel 1.25 and mason 0.2.0, flags not intended for mason must follow a double dash -- regardless of if they conflict or not.
