### Using a `slog.Handler` as backend for logr
Using a plain `slog.Handler` without support for logr works better than the

with logr implementations without slog support is not important, then
`slog.Valuer` is sufficient.
## Context support for slog
### Context support for slog
Storing a logger in a `context.Context` is not supported by
slog. `logr.NewContext` and `logr.FromContext` can be used with slog like this
to fill this gap:
slog. `NewContextWithSlogLogger` and `FromContextAsSlogLogger` can be
used to fill this gap. They store and retrieve a `slog.Logger` pointer
under the same context key that is also used by `NewContext` and
`FromContext` for `logr.Logger` value.
func HandlerFromContext(ctx context.Context) slog.Handler {
logger, err := logr.FromContext(ctx)
if err == nil {
return slogr.NewSlogHandler(logger)
}
return slog.Default().Handler()
}
When `NewContextWithSlogLogger` is followed by `FromContext`, the latter will
automatically convert the `slog.Logger` to a
`logr.Logger`. `FromContextAsSlogLogger` does the same for the other direction.
func ContextWithHandler(ctx context.Context, handler slog.Handler) context.Context {
return logr.NewContext(ctx, slogr.NewLogr(handler))
}
With this approach, binaries which use either slog or logr are as efficient as
possible with no unnecessary allocations. This is also why the API stores a
`slog.Logger` pointer: when storing a `slog.Handler`, creating a `slog.Logger`
on retrieval would need to allocate one.
The downside is that storing and retrieving a `slog.Handler` needs more
allocations compared to using a `logr.Logger`. Therefore the recommendation is
to use the `logr.Logger` API in code which uses contextual logging.
The downside is that switching back and forth needs more allocations. Because
logr is the API that is already in use by different packages, in particular
Kubernetes, the recommendation is to use the `logr.Logger` API in code which
uses contextual logging.
An alternative to adding values to a logger and storing that logger in the
context is to store the values in the context and to configure a logging
backend to extract those values when emitting log entries. This only works when
log calls are passed the context, which is not supported by the logr API.
With the slog API, it is possible, but not
required. https://github.com/veqryn/slog-context is a package for slog which
provides additional support code for this approach. It also contains wrappers
for the context functions in logr, so developers who prefer to not use the logr
APIs directly can use those instead and the resulting code will still be
interoperable with logr.

// Package klog implements logging analogous to the Google-internal C++ INFO/ERROR/V setup.
// It provides functions Info, Warning, Error, Fatal, plus formatting variants such as
// Infof. It also provides V-style logging controlled by the -v and -vmodule=file=2 flags.
// Package klog contains the following functionality:
//
// - output routing as defined via command line flags ([InitFlags])
// - log formatting as text, either with a single, unstructured string ([Info], [Infof], etc.)
// or as a structured log entry with message and key/value pairs ([InfoS], etc.)
// - management of a go-logr [Logger] ([SetLogger], [Background], [TODO])
// - helper functions for logging values ([Format]) and managing the state of klog ([CaptureState], [State.Restore])
// - wrappers for [logr] APIs for contextual logging where the wrappers can
// be turned into no-ops ([EnableContextualLogging], [NewContext], [FromContext],
// [LoggerWithValues], [LoggerWithName]); if the ability to turn off
// contextual logging is not needed, then go-logr can also be used directly
// - type aliases for go-logr types to simplify imports in code which uses both (e.g. [Logger])
// - [k8s.io/klog/v2/textlogger]: a logger which uses the same formatting as klog log with
// simpler output routing; beware that it comes with its own command line flags
// and does not use the ones from klog
// - [k8s.io/klog/v2/ktesting]: per-test output in Go unit tests
// - [k8s.io/klog/v2/klogr]: a deprecated, standalone [logr.Logger] on top of the main klog package;
// use [Background] instead if klog output routing is needed, [k8s.io/klog/v2/textlogger] if not
// - [k8s.io/klog/v2/examples]: demos of this functionality
