Feature

  • Support at the same time to console, file, URL
  • 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

Install

go get github.com/phachon/go-logger
go get ./...

Requirement

go 1.8

Support outputs

  • console // write console
  • file // write file
  • api // http request url
  • ...

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")

}

Customize Format output

Logger Message

| Field | Alias |Type | Comment | Example | |-------|-------|------|---------|----------| | Timestamp | timestamp | int64 | unix timestamp| 1521791201 | | TimestampFormat | timestampformat| string | timestamp format | 2018-3-23 15:46:41| | Millisecond | millisecond | int64 | millisecond | 1524472688352 | | MillisecondFormat | millisecondformat| string | millisecondformat | 2018-3-23 15:46:41.970 | | Level | level| int | logger level | 1 | | LevelString | levelstring | string | logger level string | Error | | Body | body | string | logger message body | this is a info log | | File | file | string | Call the file of the logger | main.go | | Line | line | int | The number of specific lines to call logger |64| | Function | function| string | The function name to call logger | main.main |

If you want to customize the format of the log output ?

config format:

consoleConfig := &go_logger.ConsoleConfig{
    Format: "%millisecond_format% [%level_string%] %body%",
}
fileConfig := &go_logger.FileConfig{
    Format: "%millisecond_format% [%level_string%] %body%",
}
output:
2018-03-23 14:55:07.003 [Critical] this is a critical log!

You can customize the format, Only needs to be satisfied Format: "%Logger Message Alias%"
