Functions ¶
func CommaNumbersLettersLeft ¶
只保留逗号以及数字和英文字母，因为逗号一般用于分隔文本
func GB18030ToUTF8 ¶
GB18030转换为UTF8，应优先使用GB18030,GB18030为GBK的超集,GBK又为GB2312的超集
func JoinInterface ¶
用分隔符sep把若干个字符或int,double等类型数据拼接在一起,实际为strings.Join的变体形式
func JoinInterface(sep string, args ...interface{}) string {
l := len(args)
switch l {
case 0:
return ""
case 1:
return fmt.Sprint(args[0])
case 2:
return fmt.Sprint(args[0]) + sep + fmt.Sprint(args[1])
case 3:
return fmt.Sprint(args[0]) + sep + fmt.Sprint(args[1]) + sep + fmt.Sprint(args[2])
}
var buffer bytes.Buffer
//前面若干条中间要加sep
for i := 0; i < l-1; i++ {
buffer.WriteString(fmt.Sprint(args[i]) + sep)
}
//最后次不加sep
buffer.WriteString(fmt.Sprint(args[l-1]))
return buffer.String()
}
func JoinStrings ¶
用分隔符sep把若干个字符拼接在一起,实际为strings.Join的变体形式
func LeftPad ¶
返回字符串str，左面用字符串padstr填补直到str是len个字符长,,此函数与mysql中LPAD()行为保持一致 LeftPad("hello", 4, " ") => "hello" LeftPad("hello", 10, " ") => " hello" LeftPad("hello", 10, "123") => "12312hello"
func LeftRightPad ¶
返回两侧字符按一定规则替换后的字符串接 LeftRightPad("hello", 4, " ") => "hell" LeftRightPad("hello", 10, " ") => " hello " LeftRightPad("hello", 10, "123") => "12hello123"
func MostSimilar ¶
返回最相似的一个字符串，前缀匹配优先 用于特定的项目 如果一点相似度都没有，则返回空
func MostSimilarWithScore ¶
func MostSimilarWithScore(a string, b []string) *similarity.Match
返回相似度最高的那个字符串 并且带匹配度 此为通用算法
func RelevantCharactersLeft ¶
保留输入的相关字符
