// Use GetOrSet to set the value for the key "root" to 3 if it doesn't exist,
// and then print whether the value is equal to 3.
gos.GetOrSet("root", ref.Of(3))

Parameters:

- fn (func(T) T): The function to be applied to each element of the slice.

Returns:

- Slice[T]: A new slice containing the results of applying the function to each element of the current slice.

Example usage:

The function iterates over the elements of the slice and applies the provided function to each element. If the length of the slice is less than a predefined threshold (max), it falls back to the sequential Map function. Otherwise, the slice is divided into two halves and the function is applied to each half in parallel using goroutines. The resulting slices are then combined to form the final output slice.

Note: The order of the elements in the output slice may not be the same as the input slice due to parallel processing.

Parameters:

- fn (func(T) T): The function to be applied to each element of the slice.

Returns:

- Slice[T]: A new slice with the results of applying the given function to each element of the original slice.

Returns:

- Slice[T]: A new Slice containing the random sample of elements from the specified subrange.

If the start index is negative, it represents the position from the end of the slice counted from the start index. If the start index is greater than or equal to the end index, an empty slice is returned. If the end index is greater than the length of the slice, it is set to the length of the slice.

Parameters:

The function iterates over the elements of the slice and applies the provided reducer function to each element in a pairwise manner. If the length of the slice is less than a predefined threshold (max), it falls back to the sequential Reduce function. Otherwise, the slice is divided into two halves and the reducer function is applied to each half in parallel using goroutines. The resulting values are combined using the reducer function to produce the final output value.

Note: Due to parallel processing, the order in which the reducer function is applied to the elements may not be the same as the input slice.

Parameters:

- fn (func(T, T) T): The reducer function to be applied to each element of the slice.

- initial (T): The initial value to be used as the starting point for the reduction.

func (String) ReplaceMulti 

func (s String) ReplaceMulti(oldnew ...String) String

ReplaceMulti creates a custom replacer to perform multiple string replacements.

Parameters:

- oldnew ...String: Pairs of strings to be replaced. Specify as many pairs as needed.

Returns:

- String: A new string with replacements applied using the custom replacer.

Example usage: 

original := g.String("Hello, world! This is a test.")
replaced := original.ReplaceMulti(
    "Hello", "Greetings",
    "world", "universe",
    "test", "example",
)
// replaced contains "Greetings, universe! This is an example."

func (String) ReplaceNth 

func (s String) ReplaceNth(oldS, newS String, n int) String

ReplaceNth returns a new String instance with the nth occurrence of oldS replaced with newS. If there aren't enough occurrences of oldS, the original String is returned. If n is less than -1, the original String is also returned. If n is -1, the last occurrence of oldS is replaced with newS.

Returns:

- A new String instance with the nth occurrence of oldS replaced with newS.

Example usage: 

s := g.String("The quick brown dog jumped over the lazy dog.")
result := s.ReplaceNth("dog", "fox", 2)
fmt.Println(result)

Output: "The quick brown dog jumped over the lazy fox.".

func (String) ReplaceRegexp 

func (s String) ReplaceRegexp(pattern *regexp.Regexp, newS String) String

ReplaceRegexp replaces all occurrences of the regular expression matches in the String with the provided newS (as a String) and returns the resulting String after the replacement.

func (String) Reverse 

func (s String) Reverse() String

Reverse reverses the String.

func (String) RightJustify 

func (s String) RightJustify(length int, pad String) String

RightJustify justifies the String to the right by adding padding to the left, up to the specified length. If the length of the String is already greater than or equal to the specified length, or the pad is empty, the original String is returned.

The padding String is repeated as necessary to fill the remaining length. The padding is added to the left of the String.

Parameters:

  • length: The desired length of the resulting justified String.
  • pad: The String used as padding.

Example usage: 

s := g.String("Hello")
result := s.RightJustify(10, "...")
// result: ".....Hello"

func (String) Similarity 

func (s String) Similarity(str String) Float

Similarity calculates the similarity between two Strings using the Levenshtein distance algorithm and returns the similarity percentage as an Float.

The function compares two Strings using the Levenshtein distance, which measures the difference between two sequences by counting the number of single-character edits required to change one sequence into the other. The similarity is then calculated by normalizing the distance by the maximum length of the two input Strings.

Parameters:

- str (String): The String to compare with s.

Returns:

- Float: The similarity percentage between the two Strings as a value between 0 and 100.

Example usage: 

s1 := g.String("kitten")
s2 := g.String("sitting")
similarity := s1.Similarity(s2) // 57.14285714285714

func (String) Split 

func (s String) Split(sep ...String) Slice[String]

Split splits the String by the specified separator.

func (String) SplitLines added in v1.1.3 

func (s String) SplitLines() Slice[String]

func (String) SplitN 

func (s String) SplitN(sep String, n Int) Slice[String]

SplitN splits the String into substrings using the provided separator and returns an Slice[String] of the results. The n parameter controls the number of substrings to return: - If n is negative, there is no limit on the number of substrings returned. - If n is zero, an empty Slice[String] is returned. - If n is positive, at most n substrings are returned.

func (String) SplitRegexp 

func (s String) SplitRegexp(pattern regexp.Regexp) Slice[String]

SplitRegexp splits the String into substrings using the provided regular expression pattern and returns an Slice[String] of the results. The regular expression pattern is provided as a regexp.Regexp parameter.

func (String) SplitRegexpN 

func (s String) SplitRegexpN(pattern regexp.Regexp, n Int) Option[Slice[String]]

SplitRegexpN splits the String into substrings using the provided regular expression pattern and returns an Slice[String] of the results. The regular expression pattern is provided as a regexp.Regexp parameter. The n parameter controls the number of substrings to return: - If n is negative, there is no limit on the number of substrings returned. - If n is zero, an empty Slice[String] is returned. - If n is positive, at most n substrings are returned.

func (String) StartsWith 

func (s String) StartsWith(prefixes ...String) bool

StartsWith checks if the String starts with any of the provided prefixes. The method accepts a variable number of arguments, allowing for checking against multiple prefixes at once. It iterates over the provided prefixes and uses the HasPrefix function from the strings package to check if the String starts with each prefix. The function returns true if the String starts with any of the prefixes, and false otherwise.

Example usage: 

s := g.String("http://example.com")
if s.StartsWith("http://", "https://") {
   // do something
}
