go-commons

golang commonly used utils and many things else.

conf

conf is a package for reading config file for golang projects. in many cases when you need a config file to do some config, but your program or your unit tests can't read the config file correctly, because where to put the config file really sucks.

This program help your program find the real location of your config file if you don't mess it up. The recommended position of the config file is under the root of your source code. When you deploy executables the config file should be along with the executables.

supports both yaml and ini config files

examples

package goconf

import (
	"strings"
	"testing"
)

const (
	testYmlFile = "test.yaml"
	testIniFile = "test.ini"

	host = "10.1.1.1"
	port = 3306
	testName = "tom"
)

type TestYmlConf struct {
	DbAddr string `yaml:"dbAddr"`
	Port   int    `yaml:"dbPort"`
}

type TestMyConf struct {
	Mysql TestIniConf `ini:"mysql"`
	Name  string      `ini:"name"`
}

type TestIniConf struct {
	Host string `ini:"host"`
	Port int    `ini:"port"`
}

func TestYaml2Object(t *testing.T) {
	var x TestYmlConf
	err := Yaml2Object(testYmlFile, &x)
	if err != nil {
		t.FailNow()
	}
	if !strings.EqualFold(x.DbAddr, host) || x.Port != port {
		t.FailNow()
	}
}

func TestIni2Object(t *testing.T) {
	var x TestMyConf
	err := Ini2Object(testIniFile, &x)
	if err != nil {
		t.FailNow()
	}
	if !strings.EqualFold(x.Mysql.Host, host) || x.Mysql.Port != port || !strings.EqualFold(testName, x.Name) {
		t.FailNow()
	}
}

log

a simple tool to use logrus as a logger and with simple configurations

You can use the struct from our package, in your configuration object, and pass the configuration object to log.GetLogger(conf), it will work.

// supporting ini/yaml/json
type LogSettings struct {
	Output       string `json:"output" yaml:"output" ini:"output"`
	Format       string `json:"format" yaml:"format" ini:"format"`
	Level        string `json:"level" yaml:"level" ini:"level"`
	ReportCaller bool   `json:"reportCaller" yaml:"report-caller" ini:"report-caller"`
}

package any
import (
 "fmt"
 "github.com/winjeg/go-commons/log"
)


var logger = log.GetLogger(nil)
func loggerTest() {
        // Debug, Warn, Trace, Error
    	logger.Info("Something noteworthy happened!")
}


func TestNewLogger(t *testing.T) {
	settings.FileConfig = &RotateFileConfig{
		Filename:   "E:/Desktop/a.log",
		MaxSize:    500,
		MaxBackups: 7,
		MaxAge:     7,
		Level:      logrus.DebugLevel,
		Formatter:  &logrus.TextFormatter{
		},
	}
	l := NewLogger(settings)
	l.Info("hello, world!")
}


// want to read log file config ?
var logger = log.GetLogger(config)
// this config should not be a pointer, it should be a struct contains the LogSettings member

http client

a simple client to make remote http request and return string response body

currently supported method:

1. Get
2. Put (content type: json)
3. Post (content type: json)
4. Delete (content type: json)

example

package any
import (
	"fmt"
	"github.com/winjeg/go-commons/httpclient"
)

func test() {
    fmt.Println(httpclient.Get("https://www.google.com"))
}

str

some utilities for str operation

func TestUUID(t *testing.T) {
	id1 := UUID()
	id2 := UUID()
	assert.NotEqual(t, id1, id2)
}

uid

both string unique id and numeric unique id is supported.

properties

read properties from string or from file,and convert a map to a property file

ip=127.0.0.1
name=tom

how to contribute

I am not rule follower, so if you want to use the project, or you want to write some code for it, just fork it and make pull requests.
Only one thing needs to be cared, the version problem. You need to test it before tagging it.

• Small changes will happen on the third digit of the version(tag).
• Medium changes will happen on the second digit of the version(tag).
• Big changes will happen on the first digit of the version(tag).
