logger crate catches Clion stop signal about env_logger

[epage]

By "exit immediately", you are referring to a panic from a broken pipe? That is not expected behavior and we try to avoid it (e.g. #221).

println panics on a broken pipe error. It is generally best to use writeln and handle the broken pipe error as works best in your application. For example, a tool like ripgrep might decide that it should exit early with a success exit code on a broken pipe.

.is_test(true) is a hack to take advantage of a hack in std / test. The default test harness, test, uses an unstable hook into std to capture the output from print/println so that it can hide it by default and then only print it along with the test failure. .is_test(true) forces env_logger to go through println so logged messages from a test can be captured with the test.

As this is working as expected, I'm going to go ahead and close this.
