The mem package provides types and functions for measuring and displaying memory throughput and capacity.
Walk the directory tree of the current directory and list all (non-hidden) files and the corresponding file sizes.
package main
import (
"fmt"
"io/fs"
"path/filepath"
"strings"
"aead.dev/mem"
)
func main() {
const Directory = "."
filepath.WalkDir(Directory, func(path string, entry fs.DirEntry, err error) error {
if entry.IsDir() {
if entry.Name() != Directory && strings.HasPrefix(entry.Name(), ".") { // Skip hidden sub directories
return filepath.SkipDir
}
fmt.Println(entry.Name())
return nil
}
stat, err := entry.Info()
if err == nil {
var size mem.Size = mem.Size(stat.Size())
fmt.Printf(" %-20s %10s\n", stat.Name(), mem.FormatSize(size, 'D', 2))
}
return nil
})
