> The logging library used by go-ipfs
|
|
|
|
go-log wraps [zap](https://github.com/uber-go/zap) to provide a logging facade. go-log manages logging
|
|
instances and allows for their levels to be controlled individually.
|
|
|
|
## Install
|
|
|
|
```sh
|
|
go get github.com/ipfs/go-log
|
|
```
|
|
|
|
## Usage
|
|
|
|
Once the package is imported under the name `logging`, an instance of `EventLogger` can be created like so:
|
|
|
|
```go
|
|
var log = logging.Logger("subsystem name")
|
|
```
|
|
|
|
It can then be used to emit log messages in plain printf-style messages at seven standard levels:
|
|
|
|
Levels may be set for all loggers:
|
|
|
|
```go
|
|
lvl, err := logging.LevelFromString("error")
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
logging.SetAllLoggers(lvl)
|
|
```
|
|
|
|
or individually:
|
|
|
|
```go
|
|
lvl, err := logging.LevelFromString("error")
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
logging.SetLogLevel("foo", "info")
|
|
```
|
