Because +of a conflict in the parameters of the common `Enabled` method, it is [not +possible to implement both slog.Handler and logr.Sink in the same +type](https://github.com/golang/go/issues/59110). + +If both are supported, log calls can go from the high-level APIs to the backend +without the need to convert parameters. `FromSlogHandler` and `ToSlogHandler` can +convert back and forth without adding additional wrappers, with one exception: +when `Logger.V` was used to adjust the verbosity for a `slog.Handler`, then +`ToSlogHandler` has to use a wrapper which adjusts the verbosity for future +log calls. + +Such an implementation should also support values that implement specific +interfaces from both packages for logging (`logr.Marshaler`, `slog.LogValuer`, +`slog.GroupValue`). logr does not convert those. + +Not supporting slog has several drawbacks: +- Recording source code locations works correctly if the handler gets called + through `slog.Logger`, but may be wrong in other cases. That's because a + `logr.Sink` does its own stack unwinding instead of using the program counter + provided by the high-level API. +- slog levels <= 0 can be mapped to logr levels by negating the level without a + loss of information. But all slog levels > 0 (e.g. `slog.LevelWarning` as + used by `slog.Logger.Warn`) must be mapped to 0 before calling the sink + because logr does not support "more important than info" levels. +- The slog group concept is supported by prefixing each key in a key/value + pair with the group names, separated by a dot. For structured output like + JSON it would be better to group the key/value pairs inside an object. +- Special slog values and interfaces don't work as expected. +- The overhead is likely to be higher. + +These drawbacks are severe enough that applications using a mixture of slog and +logr should switch to a different backend. + +### Using a `slog.Handler` as backend for logr + +Using a plain `slog.Handler` without support for logr works better than the +other direction: +- All logr verbosity levels can be mapped 1:1 to their corresponding slog level + by negating them. +- Stack unwinding is done by the `SlogSink` and the resulting program + counter is passed to the `slog.Handler`. +- Names added via `Logger.WithName` are gathered and recorded in an additional + attribute with `logger` as key and the names separated by slash as value. +- `Logger.Error` is turned into a log record with `slog.LevelError` as level + and an additional attribute with `err` as key, if an error was provided. + +The main drawback is that `logr.Marshaler` will not be supported. Types should +ideally support both `logr.Marshaler` and `slog.Valuer`. If compatibility +with logr implementations without slog support is not important, then +`slog.Valuer` is sufficient. + +### Context support for slog + +Storing a logger in a `context.Context` is not supported by +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. + +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. + +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 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.
