• console output fonts can be colored with
• File output supports three types of segmentation based on the size of the file, the number of file lines, and the date.
• file output support is saved to different files at the log level.
• Two ways of writing to support asynchronous and synchronous
• Support json format output
• The code is designed to be extensible, and you can design your own adapter as needed

Quick Used

• sync

import (
    "github.com/phachon/go-logger"
)
func main()  {
    logger := go_logger.NewLogger()

    logger.Info("this is a info log!")
    logger.Errorf("this is a error %s log!", "format")
}

• async

import (
    "github.com/phachon/go-logger"
)
func main()  {
    logger := go_logger.NewLogger()
    logger.SetAsync()

    logger.Info("this is a info log!")
    logger.Errorf("this is a error %s log!", "format")

    // Flush must be called before the end of the process
    logger.Flush()
}

• Multiple output

import (
    "github.com/phachon/go-logger"
)
func main()  {
    logger := go_logger.NewLogger()

    logger.Detach("console")

    // console adapter config
    consoleConfig := &go_logger.ConsoleConfig{
        Color: true, // Does the text display the color
        JsonFormat: true, // Whether or not formatted into a JSON string
        Format: "", // JsonFormat is false, logger message output to console format string
    }
    // add output to the console
    logger.Attach("console", go_logger.LOGGER_LEVEL_DEBUG, consoleConfig)

    // file adapter config
    fileConfig := &go_logger.FileConfig {
        Filename : "./test.log", // The file name of the logger output, does not exist automatically
        // If you want to separate separate logs into files, configure LevelFileName parameters.
        LevelFileName : map[int]string {
            logger.LoggerLevel("error"): "./error.log",    // The error level log is written to the error.log file.
            logger.LoggerLevel("info"): "./info.log",      // The info level log is written to the info.log file.
            logger.LoggerLevel("debug"): "./debug.log",    // The debug level log is written to the debug.log file.
        },
        MaxSize : 1024 * 1024,  // File maximum (KB), default 0 is not limited
        MaxLine : 100000, // The maximum number of lines in the file, the default 0 is not limited
        DateSlice : "d",  // Cut the document by date, support "Y" (year), "m" (month), "d" (day), "H" (hour), default "no".
        JsonFormat: true, // Whether the file data is written to JSON formatting
        Format: "", // JsonFormat is false, logger message written to file format string
    }
    // add output to the file
    logger.Attach("file", go_logger.LOGGER_LEVEL_DEBUG, fileConfig)


    logger.Info("this is a info log!")
    logger.Errorf("this is a error %s log!", "format")
