action_stdout_on_success

Specifies how Dune should handle the standard output of actions when they succeed. This can be used to reduce the noise of large builds.

(action_stdout_on_success <setting>)

where <setting> is one of:

• print prints the output on the terminal. This is the default.

• swallow ignores the output and does not print it on the terminal.

• must-be-empty enforces that the output should be empty. If it is not, Dune will fail.
