# log
|
|
|
|
Package log provides a uniform method of logging.
|
|
|
|
## how to use this?
|
|
|
|
just import this module into your Go project by adding the following
|
|
line to your imports:
|
|
```go
|
|
"git.stinnesbeck.com/go/log"
|
|
```
|
|
|
|
You can use this package in your code as follows:
|
|
```go
|
|
log.Print(LOGLEVEL, "This is your message of type LOGLEVEL")
|
|
log.PrintInfo("This is your info message")
|
|
log.PrintWarning("This is your warning message")
|
|
log.PrintError("This is your error message")
|
|
log.PrintDebug("This is your debug message")
|
|
```
|
|
|
|
## Log levels
|
|
|
|
The following log levels are supported:
|
|
|
|
| LogLevel | Name |
|
|
|----------|---------|
|
|
| 0 | ERROR |
|
|
| 1 | WARNING |
|
|
| 2 | INFO |
|
|
| 3 | DEBUG |
|
|
|
|
The package will honor a globally set environment variable `LOGLEVEL`. The package will only print levels that are less or equal than the one provided (e.g. `WARNING` will only print `ERROR` and `WARNING`). If no environment variable is set or it can't be parsed into the names above, ERROR will be selected as the default.
