Variables ¶
var ( ErrInvalidArgument = errors.New("invalid argument") ErrPermissionDenied = errors.New("permission denied") ErrAlreadyExist = errors.New("resource already exists") ErrNotExist = errors.New("resource does not exist") )
Common Errors forming the base of our error system
Many Errors returned by Gitea can be tested against these errors using errors.Is.
var ErrNotEmpty = errors.New("not-empty")
ErrNotEmpty is an error reported when there is a non-empty reader
Functions ¶
func AESGCMDecrypt ¶
AESGCMDecrypt (from legacy package): decrypts ciphertext with the given key using AES in GCM mode. should be replaced.
func AESGCMEncrypt ¶
AESGCMEncrypt (from legacy package): encrypts plaintext with the given key using AES in GCM mode. should be replaced.
func CommonSkip ¶
CommonSkip will check a provided name to see if it represents file or directory that should not be watched
func ContrastColor ¶
ContrastColor returns a black or white foreground color that the highest contrast ratio. In the future, the APCA contrast function, or CSS `contrast-color` will be better. https://github.com/color-js/color.js/blob/eb7b53f7a13bb716ec8b28c7a56f052cd599acd9/src/contrast/APCA.js#L42
func CreatePublicKeyFingerprint ¶
CreatePublicKeyFingerprint creates a fingerprint of the given key. The fingerprint is the sha256 sum of the PKIX structure of the key.
func CryptoRandomBytes ¶
CryptoRandomBytes generates `length` crypto bytes This differs from CryptoRandomString, as each byte in CryptoRandomString is generated by [0,61] range This function generates totally random bytes, each byte is generated by [0,255] range
func CryptoRandomInt ¶
CryptoRandomInt returns a crypto random integer between 0 and limit, inclusive
func CryptoRandomString ¶
CryptoRandomString generates a crypto random alphanumerical string, each byte is generated by [0,61] range
func FilePathJoinAbs ¶
FilePathJoinAbs joins the path elements into a single file path, each element is cleaned by filepath.Clean separately. All slashes/backslashes are converted to path separators before cleaning, the result only contains path separators. The first element must be an absolute path, caller should prepare the base path. It's caller's duty to make every element not bypass its own directly level, to avoid security issues. Like PathJoinRel, any redundant part (empty, relative dots, slashes) is removed.
{`/foo`, ``, `bar`} => `/foo/bar`
{`/foo`, `..`, `bar`} => `/foo/bar`
func FileURLToPath ¶
FileURLToPath extracts the path information from a file://... url. It returns an error only if the URL is not a file URL.
func GenerateKeyPair ¶
GenerateKeyPair generates a public and private keypair
func GetRelativeLuminance ¶
GetRelativeLuminance returns relative luminance for a SRGB color - https://en.wikipedia.org/wiki/Relative_luminance Keep this in sync with web_src/js/utils/color.js
func HexToRBGColor ¶
HexToRBGColor parses color as RGB values in 0..255 range from the hex color string (with or without #)
func HomeDir ¶
HomeDir returns path of '~'(in Linux) on Windows, it returns error when the variable does not exist.
func IfZero ¶
func IfZero[T comparable](v, def T) T
IfZero returns "def" if "v" is a zero value, otherwise "v"
func IsDir ¶
IsDir returns true if given path is a directory, or returns false when it's a file or does not exist.
func IsEmptyReader ¶
IsEmptyReader reads a reader and ensures it is empty
func IsEmptyString ¶
IsEmptyString checks if the provided string is empty
func IsExist ¶
IsExist checks whether a file or directory exists. It returns false when the file or directory does not exist.
func IsFile ¶
IsFile returns true if given path is a file, or returns false when it's a directory or does not exist.
func IsReadmeFileExtension ¶
IsReadmeFileExtension reports whether name looks like a README file based on its name. It will look through the provided extensions and check if the file matches one of the extensions and provide the index in the extension list. If the filename is `readme.` with an unmatched extension it will match with the index equaling the length of the provided extension list. Note that the '.' should be provided in ext, e.g ".md"
func IsReadmeFileName ¶
IsReadmeFileName reports whether name looks like a README file based on its name.
func KeysOfMap ¶
func KeysOfMap[K comparable, V any](m map[K]V) []K
TODO: Replace with "maps.Keys" once available, current it only in golang.org/x/exp/maps but not in standard library
func NewAlreadyExistErrorf ¶
NewAlreadyExistErrorf returns an error that formats as the given text but unwraps as an ErrAlreadyExist
func NewInvalidArgumentErrorf ¶
NewInvalidArgumentErrorf returns an error that formats as the given text but unwraps as an ErrInvalidArgument
func NewNotExistErrorf ¶
NewNotExistErrorf returns an error that formats as the given text but unwraps as an ErrNotExist
func NewPermissionDeniedErrorf ¶
NewPermissionDeniedErrorf returns an error that formats as the given text but unwraps as an ErrPermissionDenied
func NewSilentWrapErrorf ¶
NewSilentWrapErrorf returns an error that formats as the given text but unwraps as the provided error
func NormalizeEOL ¶
NormalizeEOL will convert Windows (CRLF) and Mac (CR) EOLs to UNIX (LF)
func OptionalArg ¶
func OptionalArg[T any](optArg []T, defaultValue ...T) (ret T)
OptionalArg helps the "optional argument" in Golang:
func foo(optArg ...int) { return OptionalArg(optArg) }
calling `foo()` gets zero value 0, calling `foo(100)` gets 100
func bar(optArg ...int) { return OptionalArg(optArg, 42) }
calling `bar()` gets default value 42, calling `bar(100)` gets 100
Passing more than 1 item to `optArg` or `defaultValue` is undefined behavior. At the moment only the first item is used.
func OptionalBoolParse ¶
OptionalBoolParse get the corresponding optional.Option[bool] of a string using strconv.ParseBool
func PaginateSlice ¶
PaginateSlice cut a slice as per pagination options if page = 0 it do not paginate
func PathEscapeSegments ¶
PathEscapeSegments escapes segments of a path while not escaping forward slash
func PathJoinRel ¶
PathJoinRel joins the path elements into a single path, each element is cleaned by path.Clean separately. It only returns the following values (like path.Join), any redundant part (empty, relative dots, slashes) is removed. It's caller's duty to make every element not bypass its own directly level, to avoid security issues.
empty => ``
`` => ``
`..` => `.`
`dir` => `dir`
`/dir/` => `dir`
`foo\..\bar` => `foo\..\bar`
{`foo`, ``, `bar`} => `foo/bar`
{`foo`, `..`, `bar`} => `foo/bar`
func PathJoinRelX ¶
PathJoinRelX joins the path elements into a single path like PathJoinRel, and covert all backslashes to slashes. (X means "extended", also means the combination of `\` and `/`). It's caller's duty to make every element not bypass its own directly level, to avoid security issues. It returns similar results as PathJoinRel except:
`foo\..\bar` => `bar` (because it's processed as `foo/../bar`)
All backslashes are handled as slashes, the result only contains slashes.
func ReadAtMost ¶
ReadAtMost reads at most len(buf) bytes from r into buf. It returns the number of bytes copied. n is only less than len(buf) if r provides fewer bytes. If EOF or ErrUnexpectedEOF occurs while reading, err will be nil.
func ReadWithLimit ¶
ReadWithLimit reads at most "limit" bytes from r into buf. If EOF or ErrUnexpectedEOF occurs while reading, err will be nil.
func SanitizeCredentialURLs ¶
SanitizeCredentialURLs remove all credentials in URLs (starting with "scheme://") for the input string: "https://user:pass@domain.com" => "https://sanitized-credential@domain.com"
func SanitizeErrorCredentialURLs ¶
SanitizeErrorCredentialURLs wraps the error and make sure the returned error message doesn't contain sensitive credentials in URLs
func SanitizeURL ¶
func SecToTime ¶
SecToTime converts an amount of seconds to a human-readable string. E.g. 66s -> 1 minute 6 seconds 52410s -> 14 hours 33 minutes 563418 -> 6 days 12 hours 1563418 -> 2 weeks 4 days 3937125s -> 1 month 2 weeks 45677465s -> 1 year 6 months
func ShellEscape ¶
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 SliceContainsString ¶
SliceContainsString sequential searches if string exists in slice.
func SliceRemoveAll ¶
func SliceRemoveAll[T comparable](slice []T, target T) []T
SliceRemoveAll removes all the target elements from the slice.
func SliceSortedEqual ¶
func SliceSortedEqual[T comparable](s1, s2 []T) bool
SliceSortedEqual returns true if the two slices will be equal when they get sorted. It doesn't require that the slices have been sorted, and it doesn't sort them either.
func SplitStringAtByteN ¶
SplitStringAtByteN splits a string at byte n accounting for rune boundaries. (Combining characters are not accounted for.)
func SplitTrimSpace ¶
SplitTrimSpace splits the string at given separator and trims leading and trailing space
func StatDir ¶
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 TimeEstimateParse ¶
func TimeEstimateString ¶
func ToPointer ¶
func ToPointer[T any](val T) *T
ToPointer returns the pointer of a copy of any given value
func ToSnakeCase ¶
ToSnakeCase convert the input string to snake_case format.
Some samples.
"FirstName" => "first_name" "HTTPServer" => "http_server" "NoHTTPS" => "no_https" "GO_PATH" => "go_path" "GO PATH" => "go_path" // space is converted to underscore. "GO-PATH" => "go_path" // hyphen is converted to underscore.
func ToTitleCase ¶
ToTitleCase returns s with all english words capitalized
func ToTitleCaseNoLower ¶
ToTitleCaseNoLower returns s with all english words capitalized without lower-casing
func ToUpperASCII ¶
ToUpperASCII returns s with all ASCII letters mapped to their upper case.
func UnpackData ¶
UnpackData uses gob to decode the given data in sequence
func UnsafeBytesToString ¶
UnsafeBytesToString uses Go's unsafe package to convert a byte slice to a string.
func UnsafeStringToBytes ¶
UnsafeStringToBytes uses Go's unsafe package to convert a string to a byte slice.
func UseLightText ¶
func ValuesOfMap ¶
func ValuesOfMap[K comparable, V any](m map[K]V) []V
TODO: Replace with "maps.Values" once available, current it only in golang.org/x/exp/maps but not in standard library
Types ¶
type CountingReader ¶
func NewCountingReader ¶
func NewCountingReader(rd io.Reader) *CountingReader
func (*CountingReader) Count ¶
func (w *CountingReader) Count() int
type SilentWrap ¶
SilentWrap provides a simple wrapper for a wrapped error where the wrapped error message plays no part in the error message Especially useful for "untyped" errors created with "errors.New(…)" that can be classified as 'invalid argument', 'permission denied', 'exists already', or 'does not exist'
