Synopsis
Go common and huge utility functions help you to create your go program quickly and easily.
Encode
Some useful functions can be used to handle conversion of different character encoding, such as gbk to utf8.
Example:
import (huge "github.com/dablelv/go-huge-util"
)gbkStr := []byte{0xC4, 0xE3, 0xBA, 0xC3} // 你好 in gbk
utf8Str, _ := huge.GbkToUtf8(gbkStr) // 你好 in utf8
fmt.Println(string(utf8Str)) // 你好gbkStrRes, _ := huge.Utf8ToGbk(utf8Str)
fmt.Println(gbkStrRes) // [196 227 186 195]
Net
Some useful functions can be used to handle network. For example you can use IPv4StrToU32() transform ipv4 string to uint32 value.
Example:
import (huge "github.com/dablelv/go-huge-util"
)huge.IsReservedIP("0.0.0.256") // -1 invalid ip
huge.IsReservedIP("39.156.69.79") // 0 public ip
huge.IsReservedIP("127.0.0.1") // 1 reserved iphuge.IPv4StrToU32("127.0.0.1") // 2130706433
huge.U32ToIPv4Str(2130706433) // "127.0.0.1"
huge.GetNativeEndian() // LittleEndian
huge.IsLittleEndian() // true
Slice
Some useful functions can be used to handle slice.
Example:
import (huge "github.com/dablelv/go-huge-util"
)huge.UniqueIntSlice([]int{1, 2, 2, 3}) // [1 2 3]
huge.UniqueUintSlice([]uint{1, 2, 2, 3}) // [1 2 3]
huge.UniqueStrSlice([]string{"a", "b", "b", "c"}) // [a b c]huge.ReverseIntSlice([]int{1, 2, 3}) // [3 2 1]
huge.ReverseUintSlice([]uint{1, 2, 3}) // [3 2 1]
huge.ReverseStrSlice([]string{"a", "b", "c"}) // [c b a]huge.SumSlice([]int{1,2,3}) // 6
huge.SumSlice([]uint{1,2,3}) // 6
huge.SumSlice([]float32{1.1, 2.2, 3.3}) // 6.6
huge.SumSlice([]float64{1.1, 2.2, 3.3}) // 6.6huge.JoinSliceWithSep([]int{1, 2, 3}, ",") // 1,2,3
huge.JoinSliceWithSep([]uint{1, 2, 3}, ",") // 1,2,3
huge.JoinSliceWithSep([]float64{1.1, 2.2, 3.3}, ",") // 1.1,2.2,3.3
huge.JoinSliceWithSep([]string{"a", "b", "c"}, ",") // a,b,c// CRUD(Create Read Update Delete) on slice by index
fib := []int{1, 1, 2, 3, 5, 8}
r, _ := huge.InsertSliceE(fib, 6, 13) // [1 1 2 3 5 8 13]
r, _ := huge.DeleteSliceE(fib, 0) // [1 2 3 5 8]
r, _ := huge.UpdateSliceE(fib, 5, 88) // [1 1 2 3 5 88]
r, _ := huge.GetEleIndexesSliceE(fib, 1) // [0 1]// or
r := huge.InsertIntSlice(fib, 5, 13) // [1 1 2 3 5 8 13]
r := huge.DeleteIntSliceE(fib, 0) // [1 2 3 5 8]
r := huge.UpdateIntSliceE(fib, 5, 88) // [1 1 2 3 5 88]
r := huge.GetEleIndexesSlice(fib, 1) // [0 1]
SQL
Some useful functions can be used to handle sql statement.
Example:
import (huge "github.com/dablelv/go-huge-util"
)var sql = `select * from t where field1="{name}"`
huge.FormatSql(sql, map[string]string{"name": "dablelv"}, false) // select * from t where field1="dablelv"
String
Some useful functions can be used to handle string.
Example:
import (huge "github.com/dablelv/go-huge-util"
)huge.Split("a,b,c", ",") // []string{"a", "b", "c"}huge.JoinStr(",", "a", "", "b") // "a,,b"
huge.JoinStrSkipEmpty(",", "a", "", "b") // "a,b"huge.ReverseStr("abc") // "cba"huge.GetAlphanumericNumByASCII("108条梁山man") // 6
huge.GetAlphanumericNumByASCIIV2("108条梁山man") // 6
huge.GetAlphanumericNumByRegExp("108条梁山man") // 6
Struct
Some useful functions can be used to handle string.
Example:
import (huge "github.com/dablelv/go-huge-util"
)var st = struct {I intS string
}{I: 1, S: "a"}huge.Struct2Map(st) // map[I:1 S:a]
huge.Struct2MapString(st) // map[I:1 S:a]
Time
Some useful functions can be used to handle date and time.
Example:
import (huge "github.com/dablelv/go-huge-util"
)tc := huge.NewTimeCounter()
// ... // do your statements
tc.GetMs() // get the time cost in millisecondhuge.GetNowDate() // just a example, the same below. 2020-05-16
huge.GetNowTime() // 00:15:42
huge.GetNowDateTime() // 2020-05-16 00:15:42
huge.GetNowDateTimeZ() // 2020-05-16 00:15:42 +08:00huge.GetNowS() // 1589559342
huge.GetNowMs() // 1589559342963
huge.GetNowUs() // 1589559342963062
huge.GetNowNs() // 1589559342964063200huge.GetDayBeginMoment(time.Now()) // 2020-05-16 00:00:00 +0800 CST
huge.GetDayEndMoment(time.Now()) // 2020-05-16 23:59:59.999999999 +0800 CST
Type Conversion
Some useful functions can be used to convert one type to another types, such as to map or slice.
to another type
// Example to string
s, err := ToAny[string]("foo") // "foo"
s, err := ToAny[string](8) // "8"
s, err := ToAny[string](8.31) // "8.31"
s, err := ToAny[string]([]byte("one time")) // "one time"
s, err := ToAny[string](nil) // ""var foo any = "one more time"
s, err := ToAny[string](foo) // "one more time"// Example to int
i, err := ToAny[int](8) // 8
i, err := ToAny[int](8.31) // 8
i, err := ToAny[int]("8") // 8
i, err := ToAny[int](true) // 1
i, err := ToAny[int](false) // 0
i, err := ToAny[int](nil) // 0var eight any = 8
i, err := ToAny[int](eight) // 8// Example to bool
b, err := ToAny[bool]("true") // true
b, err := ToAny[bool]("false") // false
b, err := ToAny[bool]("True") // true
b, err := ToAny[bool]("False") // false
b, err := ToAny[bool](1) // true

Rand

huge.GetRandStr(3) // dAt
huge.GetRandLowerStr(3) // lts
huge.GetRandUpperStr(3) // YUT
JSON
Some convert function about to json.
student := struct {Hobby stringAge int32
}{Hobby: "pingpopng",Age: 28,
}
huge.ToIndentJSON(&student)
/*
output:
{"Hobby": "pingpopng","Age": 28
}
*/
Other
Some useful functions now unclassified. Of course, it may be classified and moved to a new go file in the future.
b, _ := VerGTVer("1.0.5", "1.0.4") // true
b, _ := VerLTVer("1.0.5", "2.0.4") // true
b, _ := VerGEVer("2.0.4", "2.0.4") // true
b, _ := VerLEVer("1.0.5", "1.0.5") // true
Summary
The above examples is just the tip of the iceberg. For more usage, please read the source code.
Due to the limited personal ability, you are welcome to criticize and correct. Of course, welcome to join in the construction of this library.
