Not Only Log

A swift macro that produces oslog with custom info.

After upgrading Xcode 15, OSLog's Logger can provide good console log display. But our custom log doesn't support that, this library makes it work in a lightweight way.

Code

Just like:

// set once
NoLogger.callback = { (type: OSLogType, message: String, attrs: Dictionary<String, Any>?) in
    print("simple type: \(type) message: \(message) dic: \(String(describing: attrs))")
}


// all log can send to `NoLogger.callback`
// **can be located to a line**

// same with `Logger().log(level: .default, "default")`
#noLog("message")
// and more custom info
#noLogError("error", attrs: ["code": 404])

// others
Logger().log(level: .info, "info")
#noLogInfo("info")
#noLogInfo("info", attrs: ["a": 2])

Logger().log(level: .debug, "debug")
#noLogDebug("debug")
#noLogDebug("debug", attrs: ["a": 3])

Logger().log(level: .error, "error")
#noLogError("error")
#noLogError("error", attrs: ["a": 4])

Logger().log(level: .fault, "fault")
#noLogFault("fault")
#noLogFault("fault", attrs: ["a": 5])

TODO List

• support Logger(subsystem: <#T##String#>, category: <#T##String#>)
• using Swift Macro writing this lib
