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` |
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 the [`slogr`](slogr)
package.
### Inspiration
Before you consider this package, please read [this blog post by the
@ -118,6 +142,91 @@ 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`. [slogr](./slogr) provides `NewLogr` and
`NewSlogHandler` API calls to 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. `slogr` itself leaves that to the caller.
## Using a `logr.Sink` as backend for slog
Ideally, a logr sink implementation should support both logr and slog by
implementing both the normal logr interface(s) and `slogr.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. `NewLogr` and `NewSlogHandler` 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
`NewSlogHandler` 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 `slogr.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. `logr.NewContext` and `logr.FromContext` can be used with slog like this
to fill this gap:
func HandlerFromContext(ctx context.Context) slog.Handler {
logger, err := logr.FromContext(ctx)
if err == nil {
return slogr.NewSlogHandler(logger)
}
return slog.Default().Handler()
}
func ContextWithHandler(ctx context.Context, handler slog.Handler) context.Context {
return logr.NewContext(ctx, slogr.NewLogr(handler))
}
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.
