# go 工具集
未完待续...
## file包
```go
import "github.com/wangxudong123/assist/file"
```
#### 文件处理
- 写文件 `func WriteFile(path, msg string, flag int, perm os.FileMode) error`
## number包
```go
import "github.com/wangxudong123/assist/number"
```
#### 数字类型转换
- string转float64`func StringToFloat64(value string) (f float64)`
- int64转float64`func Int64ToFloat64(value int64) (f float64)`
- string转float64`func StringToInt64(value string) (i int64)`
- string转int`func StringToInt(value string) (i int)`
- float64转int64`func Float64ToInt64(value float64) (i int64)`
- float64转string`func Float64ToString(value float64) (s string)`
- int64转string`func Int64ToString(value int64) (s string)`
- int64转float64`func IntToFloat64(value int) (f float64)`
#### 处理小数位
- 保留小数位`func RoundFloat64(value float64, exp int) (num float64)`
> exp 保留的位数
#### 浮点型数字比较
- 左 = 右`func (c Cmp) Equal(l, r float64) bool`
```go
res := Cpm.Equal(3, 3)
t.Log(res) //true
```
- 左 > 右`func (c Cmp) Greater(l, r float64) bool`
- 左 > 右`func (c Cmp) Smaller(l, r float64) bool`
- 左 >= 右`func (c Cmp) GreaterOrEqual(l, r float64) bool`
- 左 <= 右`func (c Cmp) SmallerOrEqual(l, r float64) bool`
#### 排序
- 初始化数组`func NewNumbers(n ...interface{}) number`
```go
//数组可以包含float64,float32,int,int64,int32
NewNumbers(3, 44, 3453, float64(4.999999999), float64(2.0000001))
```
- 找出最大值`func (n number) Max() float64`
```go
max := NewNumbers(3, 44, 3453, float64(4.999999999), float64(2.0000001)).Max()
t.Log(max) //3453
```
- 找出最小值`func (n number) Min() float64`
```go
min := NewNumbers(3, 44, 3453, float64(4.999999999), float64(2.0000001)).Min()
t.Log(min)//2.0000001
```
- 从大到小排列 `func (n number) OrderDesc() []interface{}`
> 返回数组的元素类型是原始的类型，没有做过转换
```go
desc := NewNumbers(3, 44, 3453, float64(4.999999999), float64(2.0000001)).OrderDesc()
t.Log(desc) //[3453 44 4.999999999 3 2.0000001]
```
- 从小到大排列`func (n number) OrderAsc() []interface{}`
> 返回数组的元素类型是原始的类型，没有做过转换
```go
asc := NewNumbers(3, 44, 3453, float64(4.999999999), float64(2.0000001)).OrderAsc()
t.Log(asc)//[2.0000001 3 4.999999999 44 3453]
```
#
## str包
```go
import "github.com/wangxudong123/assist/str"
```
#### 字符串处理
- 拼接字符串`func Join(arg ...interface{}) (string, error)`
```go
Join(p_int,p_int64,p_string)
```
- 首字母大写 `func Capitalize(str string) string`
- 判断首字母是否大写 `func IsStartUpper(s string) bool`
#
## time包
```go
import "github.com/wangxudong123/assist/time"
```
#### 时间转换
- 创建当前时间对象`func NewUnixNow() *theTime`
```go
NewUnixNow()
```
- 创建时间戳对象`NewUnix(unix int64) *theTime`
```go
NewUnix(1617264318)
```
- 创建格式化时间对象`NewFormat(t string) (*theTime, error)`
```go
NewFormat("2021-04-01 12:00:00")
```
- 创建iso8601时间对象`NewISO8601(iso8601 string) (*theTime, error)`
```go
NewIso8601("2019-09-11T01:54:23+00:00")
```
- 格式化时间 `func (t *theTime) ToFormat() string`
- 转时间戳 `func (t *theTime) ToUnix() int64`
- 转iso8601时间表达式 `func (t *theTime) ToIso8601() string`
- 通过时间模板格式化时间 `func (t *theTime) ToFormatForTpl(tpl string) string`
