r2pipe.vala

Vala binding for the r2pipe protocol.

Supported transports

spawn: new R2Pipe.sync ("/bin/ls")
HTTP: new R2Pipe.sync ("http://127.0.0.1:9090")
in-process pipe: new R2Pipe.sync () or new R2Pipe.sync ("#!pipe")
JSON parsing: cmdj("ij")

Build

Requirements:

valac
gio-2.0
gio-unix-2.0
json-glib-1.0
radare2 in PATH for spawn/tests

Build the example program and static library:

make -C vala

Build the test binary:

make -C vala test-vala

Run the transport tests:

make -C vala test

Install the library artifacts:

make -C vala install

Usage

Spawn a local radare2:

try {
	var r2 = new R2Pipe.sync ("/bin/ls");
	stdout.printf ("%s\n", r2.cmdSync ("?V"));
	r2.close ();
} catch (Error e) {
	stderr.printf ("%s\n", e.message);
}

Parse JSON:

try {
	var r2 = new R2Pipe.sync ("/bin/ls");
	var info = r2.cmdj ("ij");
	var obj = info.get_object ();
	stdout.printf ("%s\n", obj.get_string_member ("core"));
	r2.close ();
} catch (Error e) {
	stderr.printf ("%s\n", e.message);
}

Connect over HTTP:

r2 -q0 -e http.bind=127.0.0.1 -e http.port=9090 -c '=H' /bin/ls

try {
	var r2 = new R2Pipe.sync ("http://127.0.0.1:9090");
	stdout.printf ("%s\n", r2.cmdSync ("?V"));
	r2.close ();
} catch (Error e) {
	stderr.printf ("%s\n", e.message);
}

Use #!pipe from inside r2:

r2 -q0 -c '#!pipe ./your-vala-binary' /bin/ls

try {
	var r2 = new R2Pipe.sync ();
	stdout.printf ("%s\n", r2.cmdSync ("?e hello-from-r2"));
} catch (Error e) {
	stderr.printf ("%s\n", e.message);
}
