# 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.

## Example usage
