Terminal Console

🔧 Installation

Add the following dependency to your Package.swift file:

.package(url: "https://github.com/SLLog/SLLog", from: "1.0.0"),

💊 How To Start

1 Import

On top of your file import:

import SLLog

2 Usage

Log any information you need with Log class


Any object.


3 Initialize

Setup SLLoger

SLLog.addHandler(try! SLLogFile("path/to/directory"))

Or console handler


or both

SLLog.addHandler(SLLogConsole(), try! SLLogFile(path))

You can create your custom log handler. Simply correspond to LogHandler protocol.

public class MyHandler: LogHandler {
    open func handle(log: String, level: SLLog.LogType, file: String, line: UInt, message: Any) {
        //Do your stuff with log.

then add it to SLLog


4 Providers

SLLog can have custom providers. To add your own provider

struct MySLLogProvider: LogProvider {}

can you can use LogProvider build in method send. To send your log via SLLog.

5 SLLogConsole

Default console log:

isDebug: Bool = true,
isTerminal: Bool = {
        #if Xcode
        return false
        return true
minProductionLogType: UInt = 3
logFormat: String = ":d :t :f::l :m",
dateFormat: String? = nil,
logColors: [SLLog.LogType:LogColor]? = nil

Override argument passing it in initializer to variate ConsoleLog SLLogConsole(isDebug: true, isTerminal: false) or SLLogConsole(isTerminal: false) and so on. Use isTerminal property to choose between terminal or console settings. SLLogConsole(isTerminal: false)

To fully configure SLLog pas Configuration object during initialisation. public init(_ config: Configuration = Configuration())

By default, logs are set for a terminal. log format ":d :t :f::l :m" where

`:d` is replaced in string to display date
`:t` is replaced by log type
`:f` is replaced by file name
`:l` is replaced by line number
`:m` is replaced by message object

Default date format used by logger is as follow "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"

To get rid of default log colors pass empty dictionary in logColors or dictionary with your own definitions. For more information about terminal color take a look: https://misc.flogisoft.com/bash/tip_colors_and_formatting


LogColor is defined as follow init(_ terminal: String, _ console: String) For XCode console emoticons are used as collor.

SLLog.LogType.verbose:LogColor(TerminalColor.lightGray, "☑️"),
SLLog.LogType.info:LogColor(TerminalColor.lightCyan, "Ⓜ️"),
SLLog.LogType.debug:LogColor(TerminalColor.lightGreen, "✅"),
SLLog.LogType.warning:LogColor(TerminalColor.lightYellow, "⚠️"),
SLLog.LogType.error:LogColor(TerminalColor.lightRed, "⛔️"),

Use TerminalColor to fast access predefined colors values

5 SLLogFile

SLLogFile save logs to files which are created on daily basis. File names are as follows: "yyyy-MM-dd". Created under :yuorPath/sllogs with extension .log Default maxFilesCount is set to 3 wich means logger stores 3 files at a time. 1 file = 1 day logs
