GoUtils

GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:

• WordUtils
• RandomStringUtils
• StringUtils (partial implementation)

Installation

If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:

go get github.com/Masterminds/goutils

If you do not have Go set up on your system, please follow the Go installation directions from the documenation, and then follow the instructions above to install GoUtils.

Usage

The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the Initials function (located within the wordutils.go file).

package main

import (
    "fmt"
	"github.com/Masterminds/goutils"
)

func main() {

	// EXAMPLE 1: A goutils function which returns no errors
    fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"

}

Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the Random function (located within the randomstringutils.go file).

package main

import (
    "fmt"
    "github.com/Masterminds/goutils"
)

func main() {

    // EXAMPLE 2: A goutils function which returns an error
    rand1, err1 := goutils.Random (-1, 0, 0, true, true)  

    if err1 != nil {
		fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
	} else {
		fmt.Println(rand1)
	}

}
