funcr

Overview ¶

Package funcr implements formatting of structured log messages and optionally captures the call site and timestamp.

The simplest way to use it is via its implementation of a github.com/go-logr/logr.LogSink with output through an arbitrary "write" function. See New and NewJSON for details.

Custom LogSinks ¶

For users who need more control, a funcr.Formatter can be embedded inside your own custom LogSink implementation. This is useful when the LogSink needs to implement additional methods, for example.

Formatting ¶

This will respect logr.Marshaler, fmt.Stringer, and error interfaces for values which are being logged. When rendering a struct, funcr will use Go's standard JSON tags (all except "string").
