binarypatch

Storing & retrieving arbitrary data from program headers

Usage

Appending some data to an OSX/Darwin program:

package main

import(
  "github.com/matiasinsaurralde/binarypatch"
)

func main() {
  b := binarypatch.New( "myprogram", "darwin" )
  index := b.Locate()
  b.Write( []byte("hello"), index )

  b.WriteFile( "myprogram_with_data")
}

myprogram does the following:

package main
import(
  "fmt"
  "github.com/matiasinsaurralde/binarypatch"
)

func main() {
  b := binarypatch.ReadMyself(5, -1, "darwin")
  fmt.Println("Reading from myself: ", b, string(b) )
}

The output of the original program is:

% ./myprogram
Reading from myself:  [0 0 0 0 0] 

Then, the output of the "patched" program:

% ./myprogram_with_data
Reading from myself:  [104 101 108 108 111] hello
