Radare2

R2Pipe

Cutter

r2pipe

The simplest and most effective way to script radare2, which consists in 1 method API that takes a string representing the r2 command to run and returns the output as a string.

Checkout more examples in the r2pipe repository.

$ pip3 install r2pipe $ python3 >>> import r2pipe >>> r2 = r2pipe.open('/bin/ls') >>> print(r2.cmd('?e Hello World')) Hello World >>> r2.quit()

JSON

Many r2 commands print JSON as output when the 'j' suffix is used, many r2pipe implementations provide the `.cmdj()` API to automatically parse the json and return a native object for the language.

$ r2 /bin/ls > cat test.py import r2pipe r2 = r2pipe.open() print(r2.cmdj('ij')['core']['type']) > . test.py Executable file

Open

The argument passed to r2pipe.open() selects the way to talk to r2, this is by spawning a new process, sending commands to the r2 http webserver, using dlopen+dlsym, etc

$ r2 -c=H /bin/ls Starting http server at http://localhost:9090/ $ python >>> import r2pipe >>> r2 = r2pipe.open('http://localhost:9090/cmd')

Languages

Use r2pipe from your favourite programming language:

$ pwd ~/prg/radare2-r2pipe $ echo $(ls -F | grep /|sed -e 's./.,.') c, clojure, cxx-qt, dlang, dotnet, erlang, go, haskell, java, lisp, newlisp, nim, nodejs, ocaml, perl, php, prolog, python, r2core-js, ruby, rust, shell, swift, v, vala

Plugins

Radare2 plugins can written via r2pipe using the rlang plugins. RLang plugins run an instance of the language VM inside r2:

- io, asm, anal, bin, core plugins in !C
- faster execution of scripts
- keep global state
- repl

$ r2pm -i lang-python $ cat core-plugin.py import r2lang def pycore(a): def _call(s): if s[0:4] == "test": print("Testing Python core plugin") return 1 return 0 return { "name": "PyCore", "license": "MIT", "desc": "r2 core plugin in python", "call": _call, } r2lang.plugin('core', pycore)

Bindings

The low level C APIs are also available for other programmming language thanks to Valabind and Swig, they are not very well maintained, but they will at some point, contribs are welcome.

$ r2pm -i r2api-python $ cat test-core-api.py from r_core import RCore core = RCore() core.file_open("/bin/ls", False, 0) core.bin_load("/bin/ls", 0, 0, 0, 0, 0) entry0 = core.cmd_str("?v entry0") print(entry0)
