JJSwiftLog

JJSwiftLog screenshot

Keep the Swift log concise, and also take into account the basic functions of the log, file name, function name, number of lines and other information, built-in console and file log functions, to meet the basic needs of developers, custom logs for developers to be highly flexible.

Feature

  • ☑ Console display (Console Log), taking into account the features of NSLog

  • ☑ Log file storage (File Log), advanced properties of configuration file log

  • ☑ User-defined log, inherits JJLogObject

  • ☑ Global switch log

  • ☑ Show only the specified file log

  • ☑ Custom log filter

  • ☑ Custom log format, any combination, built-in styles for developers to choose, built-in ANSIColor format

  • ☑ Supports multi-platform iOS, MacOS, Windows and Linux

Install

  • Swift 4.0+

How to use

Quick to use

  • Import module
import JJSwiftLog
  • Quick start

It is generally recommended to initialize at the entry of the program. The console and file log are configured by default. You only need to configure the log level. example:

override func viewDidLoad() {
    super.viewDidLoad()
    JJLogger.setup(level: .verbose)

    JJLogger.verbose("verbose")
    JJLogger.debug("debug")
    JJLogger.info("info")
    JJLogger.warning("warn")
    JJLogger.error("error")
}

Advanced

  • The developer configures the log
override func viewDidLoad() {
     super.viewDidLoad()
     // filePath needs to store the path
     var file = JJFileOutput(filePath: "filePath", delegate: JJLogger, identifier: "file")
     file?.targetMaxFileSize = 1000 * 1024
     file?.targetMaxTimeInterval = 600
     file?.targetMaxLogFiles = 20
     JJLogger.addLogOutput(file)
     #if DEBUG
     JJLogger.addLogOutput(JJConsoleOutput(identifier: "console"))
     #endif
     // Note the timing of the startLogInfo call
     JJLogger.startLogInfo()
     JJLogger.verbose("verbose")
     JJLogger.debug("debug")   
     JJLogger.info("info")
     JJLogger.warning("warn")
     JJLogger.error("error")
     // Any type
     JJLogger.verbose(123)
     JJLogger.debug(1.2)
     JJLogger.info(Date())
     JJLogger.warning(["1", "2"])
}
  • JJConsoleOutput use the NSLog style, use the isUseNSLog property
let console = JJConsoleOutput()
console.isUseNSLog = false
  • JJFileOutputThere are several properties to adjust the storage file strategy

    • targetMaxFileSizeMaximum file size

    • targetMaxTimeIntervalGenerate new file interval

    • targetMaxFileSizeThe maximum number of files, if this number is exceeded, the previous files will be deleted

let file = JJFileOutput()
file?.targetMaxFileSize = 1000 * 1024
file?.targetMaxTimeInterval = 600
file?.targetMaxLogFiles = 20
  • Set enable to switch logging in real time, which is enabled by default
JJLogger.enable = true
  • Set the onlyLogFile method to make the specified file display logs
JJLogger.onlyLogFile("ViewController")
  • JJSwiftLog supports custom format logs. The following table is the correspondence between abbreviated letters:
Shorthand Describtion
%M log text
%L log level
%l log line
%F filename, without suffix
%f Function name
%D Date (currently only yyyy-MM-dd HH:mm:ss.SSSZ is supported)
%T Thread, if the main thread displays main, the child thread displays the address or QueueLabel
%t Display HH:mm:ss format
%d Display yyyy-MM-dd format
%N filename, with suffix

Example:

JJLogger.format = "%M %F %L%l %f %D"

There are also built-in styles, such as: JJLogger.format = JJSwiftLog.simpleFormat, example:

2020-04-08 22:56:54.888+0800 -> ViewController:18 - setupVendor(parameter:) method set the parameter
2020-04-08 22:56:54.889+0800 -> ViewController:28 - viewDidLoad() Start the record
2020-04-08 22:56:54.889+0800 -> ViewController:29 - viewDidLoad() Debug the world
2020-04-08 22:56:54.890+0800 -> ViewController:30 - viewDidLoad() Show log info
2020-04-08 22:56:54.890+0800 -> ViewController:31 - viewDidLoad() Build warning
2020-04-08 22:56:54.890+0800 -> ViewController:32 - viewDidLoad() can’t fetch user info without user id
  • Implement the custom interface JJLogObject as needed, the example:
public class CustomerOutput: JJLogObject {
    ///重写output即可
    open override func output(log: JJLogEntity, message: String) {

    }
    
}
  • Each JJLogObject corresponds to a formatters (formatting) and filters (filtering) attributes. You can customize the formatting and filters according to your own needs. Example:
open class CustomerFormatter: JJLogFormatterProtocol {
    public func format(log: JJLogEntity, message: String) -> String {
        return ""
    }
}
open class CustomerFilter: JJLogFilter {
    func ignore(log: JJLogEntity, message: String) -> Bool {
        return false
    }
}
  • Built-in JJFormatterLogANSIColor, you can use the terminal to view the log with color, just add the following in formatters:

The xcode console does not support ANSIColor mode, currently only tested on the terminal

let file = JJFileOutput(delegate: JJLogger, identifier: "file")
file?.targetMaxFileSize = 1000 * 1024
file?.targetMaxTimeInterval = 600
file?.targetMaxLogFiles = 20
file?.formatters = [JJFormatterLogANSIColor()]
JJLogger.addLogOutput(file!)

Example:

JJSwiftLog ANSIColor

  • Support Sentry, example:
let sentry = JJSentryOutput(sentryKey: "key", 
sentryURL: URL(string: "http://www.exmaple.com/api/5/store/")!, delegate: JJLogger)
sentry.completion = { result in
}
sentry.failure = { error in
}
JJLogger.addLogOutput(sentry)
