Logging for code running in the sandbox. The output simply goes to stderr (which gets to the
|
|
console of the Node process), but the levels allow some configuration.
|
|
|
|
We don't use the `logging` module because it assumes more about the `time` module than we have.
|
|
|
|
Usage:
|
|
import logger
|
|
log = logger.Logger(__name__, logger.DEBUG) # Or logger.WARN; default is logger.INFO.
|
|
log.info("Hello world")
|
|
-> produces "[I] [foo.bar] Hello world"
