goutils/v2/str
The str package is a part of goutils library.
It provides utility functions for string manipulation in Go.
Functions
GenRandom
func GenRandom(length int) (string, error)
Generates a random string of the specified length. This function takes an integer input representing the length and returns a string of hexadecimal characters. If the generation fails, an error is returned.
InSlice
func InSlice(strToFind string, inputSlice []string) bool
Checks if a specific string exists in a given slice. It returns true if the string is found and false otherwise.
IsNumeric
func IsNumeric(s string) bool
Checks if a given string is composed entirely of numeric characters (0-9).
ToInt64
func ToInt64(value string) (int64, error)
Converts a string to an int64 value. If the conversion fails, an error is returned.
ToSlice
func ToSlice(delimStr string, delim string) []string
Splits a given string into a slice based on the provided delimiter.
SlicesEqual
func SlicesEqual(a, b []string) bool
Compares two string slices for equality. It returns true if the slices have the same length and contain the same strings in the same order. It returns false otherwise.
Installation
To use the goutils/v2/str package, you need to install it via go get:
go get github.com/l50/goutils/v2/str
Usage
After installation, you can import it in your project:
import "github.com/l50/goutils/v2/str"

Functions ¶
func GenRandom ¶
GenRandom generates a random string of the specified length.
Parameters:
length: The length of the random string to be generated.
Returns:
string: The generated random string. error: An error if the random string generation fails.
Example:
str, err := GenRandom(10)
if err != nil {
log.Fatalf("failed to generate random string: %v", err)
}
log.Printf("Generated random string: %s\n", str)
func InSlice ¶
InSlice determines if a specified string exists in a provided slice.
Parameters:
strToFind: The string to search for in the slice. inputSlice: The slice of strings to be searched.
Returns:
bool: true if the string is found in the slice, false otherwise.
Example:
slice := []string{"apple", "banana", "cherry"} isFound := InSlice("banana", slice)
if isFound {
log.Println("Found the string in the slice.")
}
func IsNumeric ¶
IsNumeric checks if a given string is composed entirely of numeric characters (0-9). It iterates over each character in the string and checks if it can be converted to an integer without error. If all characters are numeric, the function returns true; otherwise, it returns false.
Parameters:
s: A string to check for numeric characters.
Returns:
bool: Returns true if the string is numeric, false otherwise.
Example:
str := "1234" isNum := str.IsNumeric(str)
if !isNum {
log.Printf("The string %s is not numeric.\n", str)
}
func SlicesEqual ¶
SlicesEqual compares two slices of strings for equality.
Parameters:
a: The first string slice to be compared. b: The second string slice to be compared.
Returns:
bool: true if the slices are equal (same length and same values), false otherwise.
Example:
a := []string{"apple", "banana", "cherry"} b := []string{"apple", "banana", "cherry"} isEqual := SlicesEqual(a, b)
if isEqual {
log.Println("The string slices are equal.")
} else {
log.Println("The string slices are not equal.")
}
func ToInt64 ¶
ToInt64 converts a string to an int64.
Parameters:
value: The string to be converted to int64.
Returns:
int64: The int64 equivalent of the string. error: An error if the string to int64 conversion fails.
Example:
num, err := ToInt64("1234567890")
if err != nil {
log.Fatalf("failed to convert string to int64: %v", err)
}
log.Printf("Converted string to int64: %d\n", num)
func ToSlice ¶
ToSlice converts a string to a slice of strings, using the specified delimiter.
Parameters:
delimStr: The string to be split into a slice. delim: The delimiter to be used for splitting the string.
Returns:
[]string: A slice of strings obtained by splitting the input string.
Example:
slice := ToSlice("apple,banana,cherry", ",")
for _, str := range slice {
log.Println(str)
}
