Constant Summary collapse

INVOKE_STYLE =

Controls how many times the validator is invoked.

:once -       The validator will be invoked once and passed all the
              targets.
:per_target - The validator will be invoked for each target
              separately.

:once
ALLOW_EMPTY_TARGETS =

Controls how the validator behaves if not passed any targets.

true  - PDK will not pass the globbed targets to the validator command
        and it will instead rely on the underlying tool to find its
        own default targets.
false - PDK will pass the globbed targets to the validator command.

false
