# JLog - Jollys simple logger for swift
- Logs to __both__ ~/Library/Logs/*programname*/*programname.log* as well as to *stderr*
- Logrotation
- Loglevel can be changed
It uses [swift-log](https://github.com/apple/swift-log) as well as [swift-log-format-and-pipe](https://github.com/Adorkable/swift-log-format-and-pipe)
Example progam in Sources/JLogExample uses [ArgumentParser](https://github.com/apple/swift-argument-parser):
```
import Foundation
import ArgumentParser
import JLog
struct JLogExample: ParsableCommand
{
@Flag(name: .shortAndLong, help: "optional debug output")
var debug: Int
mutating func run() throws
{
if debug > 0
{
JLog.loglevel = debug > 1 ? .trace : .debug
}
JLog.notice("notice")
JLog.info("info")
JLog.warning("warning")
JLog.error("error")
JLog.debug("debug")
JLog.trace("tracing")
}
}
JLogExample.main()
```
For commandline utilities output looks like:
```
