Sharing of implementation tips for converting string to array in Go language

In Go language, sometimes we need to convert a string into an array according to specific delimiters , which is very common when dealing with text data, configuration files, etc. This article will share some tips for converting strings to arrays, allowing you to process string conversions more conveniently in actual development.

1. Use the Split method of the strings package

The strings package in the Go language standard library provides the Split method, which can split a string into slices based on the specified delimiter. The following is a sample code:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "apple,banana,orange,grape"
    arr := strings.Split(str, ",")

    for _, v := range arr {
        fmt.Println(v)
    }
}

Run the above code, the output is:

apple
banana
orange
grape

2. Use regular expressions

If you need more complex delimiters or rules, you can Use regular expressions to convert strings to arrays. The following is a sample code that converts a space- or comma-delimited string into an array:

package main

import (
    "fmt"
    "regexp"
)

func main() {
    str := "apple banana,orange grape"
    reg := regexp.MustCompile("[,\s]+")
    arr := reg.Split(str, -1)

    for _, v := range arr {
        fmt.Println(v)
    }
}

Run the above code, the output is:

apple
banana
orange
grape

3. Custom delimiter

If you need to use a custom separator, you can use the SplitAfter method in the strings package. The sample code is as follows:

package main

import (
    "fmt"
    "strings"
)

func main() {
    str := "apple@banana@orange@grape"
    arr := strings.SplitAfter(str, "@")

    for _, v := range arr {
        fmt.Println(v)
    }
}

Run the above code, the output is:

apple@
banana@
orange@
grape
