# Motivation

Many golang libraries use the golang's `log` package to print their logs. This means that if your application

uses logrus to print structured logging, those packages will print a format that is (probably) incompatible with yours,

and you may end losing logs in your logs collector because they can't be parsed properly.

# Solution

Print the logs written using `log.Printf` through `logrus`, by setting `log.SetOutput` to an `io.Writer` implementation

that uses `logrus` as output, i.e.:

```go

	log.SetOutput(logrusiowriter.New())

```

See `example_*_test.go` files to find testable examples that serve as documentation.

# Simple solution

Or... you can simply use the standard APIs that logrus provides, i.e., this does the same as this package:

```go

    log.SetOutput(logrus.WithFields(logrus.Fields{"logger": "stdlib"}).WriterLevel(logrus.InfoLevel))

```

So, unless you want this to be configurable using an envconfig-filled struct, there's no reason to use this library.
