SimpleLogger

Prints internal debug messages normally not shown to the user; mostly useful when debugging issues

Prints logging output which represents problems the user should care about

Prints miscellaneous logging output which isn't part of the main output a user is looking for, but useful to provide context on what Mill is doing

Prints short-lived logging output where consecutive lines over-write each other; this shows up in the logger's prompt line in the multi-line prompt when Logger.withPromptLine is running.

Useful for information which is transient and disposable, e.g. progress indicators.

Returns a string representation of the object.

The default representation is platform dependent.

Prints logging output which represents warnings the user should care about

A short dash-separated prefix that is printed before every log line. Used to uniquely identify log lines belonging to this logger from log lines belonging to others, which is especially necessary in the presence of concurrency and where logs get interleaved. Typically a single ID number or sequence of numbers.

Global APIs that let the logger access the command line configuration and manipulate the global prompt, e.g. enabling or disabling it

This Logger's versions of stdin, stdout, and stderr. Typically enabled thread-locally while the logger is being used via SystemStreamsUtils.withStreams, such that every println or System.err.println goes through the logger

A version of streams without the logging prefix appended to every line. Used by the logging hierarchy to print things such that the logging prefixes can be more finely customized per logger.
