Logrus is a structured logger for Go (golang), completely API compatible with
the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
yet stable (pre 1.0). Logrus itself is completely stable and has been used in
many large deployments. The core API is unlikely to change much but please
version control your Logrus to make sure you aren't fetching latest `master` on
every build.**
the standard library logger.
**Seeing weird case-sensitive problems?** Unfortunately, the author failed to
realize the consequences of renaming to lower-case. Due to the Go package
environment, this caused issues. Regretfully, there's no turning back now.
**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
experienced problems with the upper-case variant, so the lower-case was decided.
Everything using `logrus` will need to use the lower-case:
`github.com/sirupsen/logrus`. Any package that isn't, should be changed.
I am terribly sorry for this inconvenience. Logrus strives hard for backwards
compatibility, and the author failed to realize the cascading consequences of
such a name-change. To fix Glide, see [these
To fix Glide, see [these
comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437).
For an in-depth explanation of the casing issue, see [this
comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276).
**Are you interested in assisting in maintaining Logrus?** Currently I have a
lot of obligations, and I am unable to provide Logrus with the maintainership it
needs. If you'd like to help, please reach out to me at `simon at author's
username dot com`.
