 If the Go standard library had defined an interface for logging, this project
 probably would not be needed.  Alas, here we are.

+When the Go developers started developing such an interface with
+[slog](https://github.com/golang/go/issues/56345), they adopted some of the
+logr design but also left out some parts and changed others:
+
+| Feature | logr | slog |
+|---------|------|------|
+| High-level API | `Logger` (passed by value) | `Logger` (passed by [pointer](https://github.com/golang/go/issues/59126)) |
+| Low-level API | `LogSink` | `Handler` |
+| Stack unwinding | done by `LogSink` | done by `Logger` |
+| Skipping helper functions | `WithCallDepth`, `WithCallStackHelper` | [not supported by Logger](https://github.com/golang/go/issues/59145) |
+| Generating a value for logging on demand | `Marshaler` | `LogValuer` |
+| Log levels | >= 0, higher meaning "less important" | positive and negative, with 0 for "info" and higher meaning "more important" |
+| Error log entries | always logged, don't have a verbosity level | normal log entries with level >= `LevelError` |
+| Passing logger via context | `NewContext`, `FromContext` | no API |
+| Adding a name to a logger | `WithName` | no API |
+| Modify verbosity of log entries in a call chain | `V` | no API |
+| Grouping of key/value pairs | not supported | `WithGroup`, `GroupValue` |
+| Pass context for extracting additional values | no API | API variants like `InfoCtx` |
+
+The high-level slog API is explicitly meant to be one of many different APIs
+that can be layered on top of a shared `slog.Handler`. logr is one such
+alternative API, with [interoperability](#slog-interoperability) provided by
+some conversion functions.
+
 ### Inspiration

 Before you consider this package, please read [this blog post by the
@@ -118,6 +144,103 @@ There are implementations for the following logging libraries:
 - **github.com/go-kit/log**: [gokitlogr](https://github.com/tonglil/gokitlogr) (also compatible with github.com/go-kit/kit/log since v0.12.0)
 - **bytes.Buffer** (writing to a buffer): [bufrlogr](https://github.com/tonglil/buflogr) (useful for ensuring values were logged, like during testing)

+## slog interoperability
+
+Interoperability goes both ways, using the `logr.Logger` API with a `slog.Handler`
+and using the `slog.Logger` API with a `logr.LogSink`. `FromSlogHandler` and
+`ToSlogHandler` convert between a `logr.Logger` and a `slog.Handler`.
+As usual, `slog.New` can be used to wrap such a `slog.Handler` in the high-level
+slog API.
+
+### Using a `logr.LogSink` as backend for slog
+
+Ideally, a logr sink implementation should support both logr and slog by
+implementing both the normal logr interface(s) and `SlogSink`.  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. 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.
