Constants ¶
const NoStrPos = -1
sentinel value for StrWithPos.Pos to indicate no position
Variables ¶

var HexDigits = []byte{'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'}

Functions ¶
func AddElemToSliceUniq ¶
func AddElemToSliceUniq[T comparable](arr []T, elem T) []T
func AddIntSlice ¶
Add a slice of ints, returning an error if the result overflows.
func AtomicRenameCopy ¶
func ChunkSlice ¶
func CombineMaps ¶
will overwrite m1 with m2's values
func CombineStrArrays ¶
combines string arrays and removes duplicates (returns a new array)
func CompareAsFloat64 ¶ added in v0.9.0
Helper to handle numeric comparisons as float64
func ContainsStr ¶
func CopyToChannel ¶
does *not* close outputCh on EOF or error
func CopyWithEndBytes ¶
returns (isEOF, error)
func DecodeStringArray ¶
func DetectMimeType ¶
on error just returns "" does not return "application/octet-stream" as this is considered a detection failure can pass an existing fileInfo to avoid re-statting the file
func DoMapStructure ¶
does a mapstructure using "json" tags
func EllipsisStr ¶
func EncodeStringArray ¶
func EncodeStringMap ¶
func EncodedStringArrayGetFirstVal ¶
on encoding error returns "" this is used to perform logic on first value without decoding the entire array
func GetExitCode ¶
func GetFirstLine ¶
func GetJsonTag ¶
func GetJsonTag(field reflect.StructField) string
func GetLineColFromOffset ¶ added in v0.8.12
func GetMapKeys ¶
func GetMapKeys[K comparable, V any](m map[K]V) []K
func GetOrderedMapKeys ¶
func GetOrderedStringerMapKeys ¶
func GetOrderedStringerMapKeys[K interface {
comparable
fmt.Stringer
}, V any](m map[K]V) []K
func IndentString ¶
func IsNumericType ¶ added in v0.9.0
Helper to check if a value is a numeric type
func JsonMapToStruct ¶
func JsonValEqual ¶ added in v0.9.0
this is a shallow equal, but with special handling for numeric types it will up convert to float64 and compare
func LongestPrefix ¶
func MoveSliceIdxToFront ¶
func NullDecodeStr ¶
func NullEncodeStr ¶
encodes a string, removing null/zero bytes (and separators '|') a zero byte is encoded as "\0", a '\' is encoded as "\\", sep is encoded as "\s" allows for easy double splitting (first on \x00, and next on "|")
func QuickParseJson ¶
func RandomHexString ¶
every byte is 4-bits of randomness
func ReUnmarshal ¶
func RemoveElemFromSlice ¶
func RemoveElemFromSlice[T comparable](arr []T, elem T) []T
removes an element from a slice and modifies the original slice (the backing elements) if it removes the last element from the slice, it will return nil so we free the original slice's backing memory
func ShellHexEscape ¶
returns hex escaped string (\xNN for each byte)
func SliceIdx ¶
func SliceIdx[T comparable](arr []T, elem T) int
func SortStringRunes ¶
func StarMatchString ¶
matches a delimited string with a pattern string the pattern string can contain "*" to match a single part, or "**" to match the rest of the string note that "**" may only appear at the end of the string
func StrArrayToMap ¶
func StructToJsonMap ¶
func WriteFileIfDifferent ¶ added in v0.8.7
Types ¶
type StrWithPos ¶
type StrWithPos struct {
Str string `json:"str"`
Pos int `json:"pos"` // this is a 'rune' position (not a byte position)
}
func ParseToSP ¶
func ParseToSP(s string) StrWithPos
func (StrWithPos) Append ¶
func (sp StrWithPos) Append(str string) StrWithPos
func (StrWithPos) Prepend ¶
func (sp StrWithPos) Prepend(str string) StrWithPos
func (StrWithPos) String ¶
func (sp StrWithPos) String() string
