Functions ¶
func EqualFoldWithoutChars ¶
EqualFoldWithoutChars checks string `s1` and `s2` equal case-insensitively, with/without chars '-'/'_'/'.'/' '.
func FormatCmdKey ¶
FormatCmdKey formats string `s` as command key using uniformed format.
func FormatEnvKey ¶
FormatEnvKey formats string `s` as environment key using uniformed format.
func IsArray ¶
func IsArray(value interface{}) bool
IsArray checks whether given value is array/slice. Note that it uses reflect internally implementing this feature.
func IsDebugEnabled ¶
func IsDebugEnabled() bool
IsDebugEnabled checks and returns whether debug mode is enabled. The debug mode is enabled when command argument "gf.debug" or environment "GF_DEBUG" is passed.
func IsFloat ¶
func IsFloat(value interface{}) bool
IsFloat checks whether `value` is type of float.
func IsLetterLower ¶
IsLetterLower checks whether the given byte b is in lower case.
func IsLetterUpper ¶
IsLetterUpper checks whether the given byte b is in upper case.
func IsNil ¶
func IsNil(value interface{}) bool
IsNil checks whether `value` is nil, especially for interface{} type value.
func IsNumeric ¶
IsNumeric checks whether the given string s is numeric. Note that float string like "123.456" is also numeric.
func IsSlice ¶
func IsSlice(value interface{}) bool
IsSlice checks whether `value` is type of slice.
func IsStruct ¶
func IsStruct(value interface{}) bool
IsStruct checks whether `value` is type of struct.
func ListToMapByKey ¶
ListToMapByKey converts `list` to a map[string]interface{} of which key is specified by `key`. Note that the item value may be type of slice.
func MapContainsPossibleKey ¶
MapContainsPossibleKey checks if the given `key` is contained in given map `data`. It checks the key ignoring cases and symbols.
Note that this function might be of low performance.
func MapPossibleItemByKey ¶
func MapPossibleItemByKey(data map[string]interface{}, key string) (foundKey string, foundValue interface{})
MapPossibleItemByKey tries to find the possible key-value pair for given key ignoring cases and symbols.
Note that this function might be of low performance.
func NewReadCloser ¶
func NewReadCloser(content []byte, repeatable bool) io.ReadCloser
NewReadCloser creates and returns a RepeatReadCloser object.
func RemoveSymbols ¶
RemoveSymbols removes all symbols from string and lefts only numbers and letters.
func ReplaceByMap ¶
ReplaceByMap returns a copy of `origin`, which is replaced by a map in unordered way, case-sensitively.
func SetDebugEnabled ¶
func SetDebugEnabled(enabled bool)
SetDebugEnabled enables/disables the internal debug info.
func SplitAndTrim ¶
SplitAndTrim splits string `str` by a string `delimiter` to an array, and calls Trim to every element of this array. It ignores the elements which are empty after Trim.
func StripSlashes ¶
StripSlashes un-quotes a quoted string by AddSlashes.
func Trim ¶
Trim strips whitespace (or other characters) from the beginning and end of a string. The optional parameter `characterMask` specifies the additional stripped characters.
Types ¶
type ReadCloser ¶
type ReadCloser struct {
// contains filtered or unexported fields
}
ReadCloser implements the io.ReadCloser interface which is used for reading request body content multiple times.
Note that it cannot be closed.
func (*ReadCloser) Close ¶
func (b *ReadCloser) Close() error
Close implements the io.ReadCloser interface.
func (*ReadCloser) Read ¶
func (b *ReadCloser) Read(p []byte) (n int, err error)
Read implements the io.ReadCloser interface.
