|

Logrus is a structured logger for Go (golang), completely API compatible with
|
||||
the standard library logger.
|
||||
|
||||
**Logrus is in maintenance-mode.** We will not be introducing new features. It's
|
||||
simply too hard to do in a way that won't break many people's projects, which is
|
||||
the last thing you want from your Logging library (again...).
|
||||
|
||||
This does not mean Logrus is dead. Logrus will continue to be maintained for
|
||||
security, (backwards compatible) bug fixes, and performance (where we are
|
||||
limited by the interface).
|
||||
|
||||
I believe Logrus' biggest contribution is to have played a part in today's
|
||||
widespread use of structured logging in Golang. There doesn't seem to be a
|
||||
reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
|
||||
community has built those independently. Many fantastic alternatives have sprung
|
||||
up. Logrus would look like those, had it been re-designed with what we know
|
||||
about structured logging in Go today. Check out, for example,
|
||||
[Zerolog][zerolog], [Zap][zap], and [Apex][apex].

|
||||
[apex]: https://github.com/apex/log
|
||||
|
||||
**Seeing weird case-sensitive problems?** It's in the past been possible to
|
||||
import Logrus as both upper- and lower-case. Due to the Go package environment,
|
||||
this caused issues in the community and we needed a standard. Some environments
