Functions ¶
func AppendIfMissing ¶
AppendIfMissing 如果给定字符串不是以给定的字符串为结尾，则在"尾部"添加结尾字符串（不忽略大小写）.
PS: 区分大小写.
e.g. ("abc", "c")) => "abc" ("abc", "C")) => "abcC" ("abc", "0")) => "abc0"
func AssertNotBlank ¶
func AssertNotEmpty ¶
func BlankToDefault ¶
func BytesToString ¶
BytesToString converts byte slice to string without a memory allocation.
PS: (1) copy from gin/internal/bytesconv/bytesconv.go (2) Richelieu: 感觉这样效率更高，但慎用!!!
func Count ¶
Count 计数
@return >= 0
e.g. ("12345", "3") => 1 ("12345", "6") => 0
e.g.1 If substr is an empty string, Count returns 1 + the number of Unicode code points in s. strKit.Count("12345", "") => 6
func EndWith ¶
EndWith
PS: 区分大小写.
@param s suffix不为""的情况下，如果s为""，返回值必定为false @param suffix 如果suffix为""，返回值必定为true
e.g. ""的情况 ("", "") => true ("1", "") => true ("", "1") => false
e.g.1 区分大小写 ("abc", "abc") => true ("abc", "Abc") => false
func GetRuneCount ¶
GetRuneCount
PS: (1) 包括简体、繁体. (2) 如果确定 传参str 中不存在中文字符，建议直接使用 内置函数len().
@param str （可能）带有 中文字符 的字符串
e.g. ("test") => 4 ("测试") => 2
func GetStringPtr ¶
func GetStringPtrValue ¶
GetStringPtrValue
@param ptr 不能为nil（会导致panic: runtime error: invalid memory address or nil pointer dereference）
func Index ¶
Index
PS: (1) s中不存在substr的话，返回-1 (2) s中存在多个substr的话，返回第一个的下标
@param s 被查找的字符串 @param str 查找的字符串
e.g. ("abcabc", "ab") => 0 ("bcabc", "ab") => 2 ("23", "1") => -1
func IntToString ¶
func IsAllEmpty ¶
func IsAllNotEmpty ¶
func IsEmptyString ¶
func IsEmptyString(obj interface{}) bool
func IsNotEmpty ¶
func PrependIfMissing ¶
PrependIfMissing 如果给定字符串不是以给定的字符串为开头，则在"首部"添加 起始字符串.
PS: 区分大小写.
e.g. ("abc", "a") => "abc" ("abc", "A")) => "Aabc" ("abc", "0") => "0abc"
func RemovePrefixIfExist ¶
RemovePrefixIfExist 去掉指定的"前缀"（如果存在的话）
PS: (1) 区分大小写； (2) 存在多个的话，只会移除第1个.
@param s 如果为""，返回"" @param prefix 如果为""，返回传参s
e.g. ""的情况 ("", "") => "" ("1", "") => "1" ("", "1") => ""
e.g.1 区分大小写 ("abcd", "abcd") => "" ("abcd", "Abcd") => "abcd"
func RemoveSpace ¶
RemoveSpace 移除str中所有的（包括左右的、中间的）：" "、"\t"、"\r"、"\n"...
e.g. (" \t\r\n \n\n") => ""
func RemoveSuffixIfExist ¶
RemoveSuffixIfExist 去掉指定的"后缀"（如果存在的话）
PS: (1) 区分大小写； (2) 存在多个的话，只会移除最后1个.
func ReplaceSpacesWithSpace ¶
ReplaceSpacesWithSpace 将连续的空格替换为单个空格
e.g. "It\tis\na\fsimple\rtest !" => "It is a simple test !"
func Split ¶
Split
@param sep 可以为""，此种情况比较特殊，详见下例；
如果s中不存在sep，那么返回切片的长度为1
@return 必定不为nil && len >= 1
e.g. ("", "-") => []（长度为1；唯一的元素为""） ("-", "-") => []string{"", ""} ("123-", "-") => []string{"123", ""} e.g.1 ("hello world!", "") => [h e l l o w o r l d !] ("1-2-3", "-") => [1 2 3]（长度为3） ("1-2-3", "+") => [1-2-3]（长度为1） ("172.18.21.50;8095;", ";") => [172.18.21.50 8095 ]（长度为3，第三个元素为""）
func StartWith ¶
StartWith
PS: 区分大小写.
@param s prefix不为""的情况下，如果s为""，返回值必定为false @param prefix 如果prefix为""，返回值必定为true
e.g. ""的情况 ("", "") => true ("1", "") => true ("", "1") => false
e.g.1 区分大小写 ("abc", "abc") => true ("abc", "Abc") => false
func StringToBytes ¶
StringToBytes converts string to byte slice without a memory allocation.
PS: (1) copy from gin/internal/bytesconv/bytesconv.go (2) Richelieu: 感觉这样效率更高，但慎用!!!
func SubAfterString ¶
SubAfterString
case 1: s包含str的情况，返回截取后的字符串； case 2: s不包含str的情况，直接返回s.
e.g. ("abcd", "bc") => "bcd"
func SubBeforeString ¶
SubBeforeString
case 1: s包含str的情况，返回截取后的字符串； case 2: s不包含str的情况，直接返回s.
e.g. ("abcd", "bc") => "a"
