Plexus

Plexus is an advanced, modular event framework, driven by the desire for a first-class, logging experience. While the primary goal of Plexus is to provide a first-class logging experience, it is designed with many other applications in mind.

To see an example of how Plexus works, head on over to the example. To learn about the basics, just keep reading.

Modules

Plexus uses Modules to organize and manage events. To attach a module to an arbitrary class, use with HasModule and override the package getter. The package must be a (preferably constant) list of strings containing only lowercase and uppercase letters, numbers, and underscores. It is preferable that this package follows typical reverse domain name notation, optionally omitting "ext.", instead sticking with a Dart package name.

Logging

Plexus supports logging through the module event system, aided by the Level class for filtering and organization. The Level class has a map that links Plexus levels to Dart Logging levels. Each Level instance also has a field holding its corresponding Dart Logging levels.

Plexus ships with the consoleHandler function that takes an Event and, optionally, a Stdout that defaults to Dart I/O's stdout and writes formatted log lines to the passed Stdout.
