%description
Log::ger is yet another logging framework with the following features:

* * Separation of producers and consumers/listeners

Like Log::Any, this offers a very easy way for modules to produce some logs
without having to configure anything. Configuring output, level, etc can be
done in the application as log consumers/listeners. To read more about
this, see the documentation of Log::Any or Log::ger::Manual (but
nevertheless see Log::ger::Manual on why you might prefer Log::ger to
Log::Any).

* * Lightweight and fast

*Slim distribution.* No non-core dependencies, extra functionalities are
provided in separate distributions to be pulled as needed.

*Low startup overhead.* Only ~0.5-1ms. For comparison, strict ~0.2-0.5ms,
warnings ~2ms, Log::Any (v0.15) ~2-3ms, Log::Any (v1.049) ~8-10ms,
Log::Log4perl ~35ms. This is measured on a 2014-2015 PC and before doing
any output configuration. I strive to make 'use Log::ger;' statement to be
roughly as light as 'use strict;' or 'use warnings;' so the impact of
adding the statement is really minimal and you can just add logging without
much thought to most of your modules. This is important to me because I
want logging to be pervasive.

To test for yourself, try e.g. with bencher-code:

% bencher-code 'use Log::ger' 'use Log::Any' --startup

*Fast*. Low null-/stealth-logging overhead, about 1.5x faster than
Log::Any, 3x faster than Log4perl, 5x faster than Log::Fast, ~40x faster
than Log::Contextual, and ~100x faster than Log::Dispatch.

For more benchmarks, see Bencher::Scenarios::Log::ger.

*Conditional compilation.* There is a plugin to optimize away unneeded
logging statements, like assertion/conditional compilation, so they have
zero runtime performance cost. See Log::ger::Plugin::OptAway.

Being lightweight means the module can be used more universally, from CLI
to long-running daemons to inside routines with tight loops.

* * Flexible

*Customizable levels and routine/method names.* Can be used in a procedural
or OO style. Log::ger can mimic the interface of Log::Any, Log::Contextual,
Log::Log4perl, or some other popular logging frameworks, to ease migration
or adjust with your personal style.

*Per-package settings.* Each importer package can use its own
format/layout, output. For example, a module that is migrated from Log::Any
uses Log::Any-style logging, while another uses native Log::ger style, and
yet some other uses block formatting like Log::Contextual. This eases code
migration and teamwork. Each module author can preserve her own logging
style, if wanted, and all the modules still use the same framework.

*Dynamic.* Outputs and levels can be changed anytime during run-time and
logger routines will be updated automatically. This is useful in situation
like a long-running server application: you can turn on tracing logs
temporarily to debug problems, then turn them off again, without restarting
your server.

*Interoperability.* There are modules to interop with Log::Any, either
consume Log::Any logs (see Log::Any::Adapter::LogGer) or produce logs to be
consumed by Log::Any (see Log::ger::Output::LogAny).

*Many output modules and plugins.* See 'Log::ger::Output::*',
'Log::ger::Format::*', 'Log::ger::Layout::*', 'Log::ger::Plugin::*'.
Writing an output module in Log::ger is easier than writing a
Log::Any::Adapter::*.

For more documentation, start with Log::ger::Manual.
