Revision 52c4c4570fc0a9c028ab0e3cc316f09cba0737bc authored by Chris Foster on 10 January 2018, 12:02:07 UTC, committed by Chris Foster on 11 January 2018, 10:03:59 UTC
The metadata suffix is now printed on its own line by default, and disabled for `Info` level logging. The printing can be made more compact if desired by right justifying the metadata using the `right_justify` setting. Color is made customizable by requiring that it's returned from the meta_formatter() function.
