How to search for files in only one folder; specify the current directory?

Question

go

var files []string
var my_dir = "../testDir/"
var err = filepath.Walk(my_dir, func(path string, info os.FileInfo, err error) (error) {
    if !info.IsDir() {
        var ext = filepath.Ext(path)
        if ext == ".tx" {
            files = append(files, path)
        }
    }
    return nil
})

Iterates over the specified folder and all subfolders. How to make it work only with the specified one?
And how to specify the current folder if you cannot specify a name (for example, the root folder of the site on the server)? "Current" is the folder where the application is running.

Answer 1

To specify the current folder - you can specify "dot" as the folder name so that there is no recursion - use the ioutil.ReadDir function.

package main

import (
    "fmt"
    "io/ioutil"
    "log"
)

func main() {
    // текущая папка
    files, err := ioutil.ReadDir(".")
    if err != nil {
        log.Fatal(err)
    }

    for _, file := range files {
        fmt.Println(file.Name(), file.IsDir())
    }
}
