Functions

func CopyDir

func CopyDir(srcPath, destPath string) error

CopyDir copy files recursively from source to target directory. It returns error when error occurs in underlying functions.

func CopyFile

func CopyFile(src, dest string) error

CopyFile copies file from source to target path.

func EnsureAbsolutePath

func EnsureAbsolutePath(path string, absoluteBase string) string

EnsureAbsolutePath ensure that a path is absolute, making it relative to absoluteBase if necessary

func ExistsInSlice

func ExistsInSlice(target string, slice []string) bool

ExistsInSlice returns true if string exists in slice.

func GetDirectorySize

func GetDirectorySize(path string) (int64, error)

GetDirectorySize returns the dumb disk consumption for a given path

func IsDir

func IsDir(dir string) (bool, error)

IsDir returns true if given path is a directory, or returns false when it's a file or does not exist.

func IsEmptyString

func IsEmptyString(s string) bool

IsEmptyString checks if the provided string is empty

func IsEqualSlice

func IsEqualSlice(target []string, source []string) bool

IsEqualSlice returns true if slices are equal.

func IsExist

func IsExist(path string) (bool, error)

IsExist checks whether a file or directory exists. It returns false when the file or directory does not exist.

func IsFile

func IsFile(filePath string) (bool, error)

IsFile returns true if given path is a file, or returns false when it's a directory or does not exist.

func IsInt64InSlice

func IsInt64InSlice(target int64, slice []int64) bool

IsInt64InSlice sequential searches if int64 exists in slice.

func IsSliceInt64Eq

func IsSliceInt64Eq(a, b []int64) bool

IsSliceInt64Eq returns if the two slice has the same elements but different sequences.

func IsStringInSlice

func IsStringInSlice(target string, slice []string, insensitive ...bool) bool

IsStringInSlice sequential searches if string exists in slice.

func Max

func Max(a, b int) int

Max max of two ints

func MergeInto

func MergeInto(dict map[string]interface{}, values ...interface{}) (map[string]interface{}, error)

MergeInto merges pairs of values into a "dict"

func Min

func Min(a, b int) int

Min min of two ints

func NormalizeEOL

func NormalizeEOL(input []byte) []byte

NormalizeEOL will convert Windows (CRLF) and Mac (CR) EOLs to UNIX (LF)

func PaginateSlice

func PaginateSlice(list interface{}, page, pageSize int) interface{}

PaginateSlice cut a slice as per pagination options if page = 0 it do not paginate

func PathEscapeSegments

func PathEscapeSegments(path string) string

PathEscapeSegments escapes segments of a path while not escaping forward slash

func Remove

func Remove(name string) error

Remove removes the named file or (empty) directory with at most 5 attempts.

func RemoveAll

func RemoveAll(name string) error

RemoveAll removes the named file or (empty) directory with at most 5 attempts.Remove

func SanitizeMessage

func SanitizeMessage(message, unsanitizedURL string) string

SanitizeMessage sanitizes a message which may contains a sensitive URL

func SanitizeURLCredentials

func SanitizeURLCredentials(unsanitizedURL string, usePlaceholder bool) string

SanitizeURLCredentials sanitizes a url, either removing user credentials or replacing them with a placeholder.

func ShellEscape

func ShellEscape(toEscape string) string

ShellEscape will escape the provided string. We can't just use go-shellquote here because our preferences for escaping differ from those in that we want:

* If the string doesn't require any escaping just leave it as it is. * If the string requires any escaping prefer double quote escaping * If we have ! or newlines then we need to use single quote escaping

func StatDir

func StatDir(rootPath string, includeDir ...bool) ([]string, error)

StatDir gathers information of given directory by depth-first. It returns slice of file list and includes subdirectories if enabled; it returns error and nil slice when error occurs in underlying functions, or given path is not a directory or does not exist.

Slice does not include given path itself. If subdirectories is enabled, they will have suffix '/'.

func StopTimer

func StopTimer(t *time.Timer) bool

StopTimer is a utility function to safely stop a time.Timer and clean its channel

func URLJoin

func URLJoin(base string, elems ...string) string

URLJoin joins url components, like path.Join, but preserving contents

func URLSanitizedError

func URLSanitizedError(err error, unsanitizedURL string) error

URLSanitizedError returns the sanitized version an error whose message may contain a sensitive URL
