RAPATCH

Human friendly text format to apply patches to binary files.

Patch format

Those patches must be written in files and the syntax looks like the following:

^# -> comments . -> execute command ! -> execute command OFFSET { code block } OFFSET "string" OFFSET 01020304 OFFSET : assembly

This script will run the '?e ..' command in r2 and then write the string 'Hello' at 0x200 offset

# rapatch example
:?e hello world
0x200 "Hello"

$ r2 -P rapatch.txt target-program.txt
