Xdumpgo Tutorial May 2026

Assuming you have Go installed (1.20+ recommended):

xdumpgo map 0xc00009e010

Prints key-value pairs even if the binary has no type info — attempts to infer types from memory patterns.

If you want, I can:

Since xdumpgo is not a mainstream standard command, this report assumes it refers to a Go-oriented core dump inspection utility (similar to gdump or an extended go tool objdump). If you meant something else (e.g., a custom/internal tool), please clarify. Otherwise, this tutorial-style report will be useful for practical scenarios.

diff := xdumpgo.Diff(oldData, newData)
for _, d := range diff 
    fmt.Printf("Offset 0x%X: %02X -> %02X\n", d.Offset, d.OldByte, d.NewByte)

Create a file named main.go:

package main
import (
    "fmt"
    "github.com/wjeevm/xdumpgo" // Adjust import path based on your actual source
)
func main() 
    // Define a simple struct
    user := struct 
        Name string
        Age  int
        Role string
Name: "Alice",
        Age:  30,
        Role: "Admin",
// Standard fmt output
    fmt.Println("--- Standard fmt output ---")
    fmt.Printf("%+v\n", user)
// xdumpgo output
    fmt.Println("\n--- xdumpgo output ---")
    xdumpgo.Print(user)

Output Comparison: The standard fmt package prints a flat line: Name:Alice Age:30 Role:Admin. xdumpgo will output a colored, structured view (colors represented here conceptually):

(struct  Name string; Age int; Role string ) 
    Name: (string) "Alice",
    Age:  (int) 30,
    Role: (string) "Admin",

Disable it with cfg.ASCII = false or use -x flag in CLI. xdumpgo tutorial
