Functions ¶
func Bytes2String ¶
Bytes2String converts []byte to string via direct pointer conversion. Both share the same underlying memory; modifying one affects the other. Much faster than string([]byte{}) for large conversions.
func CheckErrPanic ¶
func CheckErrPanic(err error)
func ExcelSheetNameReplace ¶
ExcelSheetNameReplace replaces invalid Excel sheet name characters with underscores.
func FileNameReplace ¶
FileNameReplace replaces invalid filename characters with similar alternatives.
func HashString ¶
func IsDirExists ¶
The IsDirExists judges path is directory or not.
func IsFileExists ¶
The IsFileExists judges path is file or not.
func JSONPToJSON ¶ added in v1.4.0
JSONPToJSON modify jsonp string to json string Example: forbar({a:"1",b:2}) to {"a":"1","b":2}
func JSONString ¶ added in v1.4.0
func JSONString(obj interface{}) string
JSONString converts obj to a JSON string.
func KeyinsParse ¶
KeyinsParse splits user-provided custom keyins into unique tokens.
func MakeUnique ¶
func MakeUnique(obj interface{}) string
MakeUnique creates a unique fingerprint for obj (method 1: FNV-64).
func Mkdir ¶
func Mkdir(filePath string) result.VoidResult
Mkdir creates the directory for the given path.
func RandomCreateBytes ¶
RandomCreateBytes generate random []byte by specify chars.
func String2Bytes ¶
String2Bytes converts string to []byte via direct pointer conversion. Both share the same underlying memory; modifying one affects the other. Do not mutate the returned slice directly (e.g. b[1]='d') or the program may panic.
func WalkRelDir ¶
WalkRelDir walks directories under targpath and returns relative paths, optionally filtered by suffixes.
func WalkRelFiles ¶
WalkRelFiles walks files under targpath and returns relative paths, optionally filtered by suffixes.
func XML2MapStr ¶ added in v1.4.0
XML2MapStr converts simple XML to a string map (supports UTF-8).
