.Sh DESCRIPTION
ragg2 is a frontend for r_egg, compile programs into tiny binaries for x86-32/64 and arm.
.Pp
This tool is experimental and it is a rewrite of the old rarc2 and rarc2-tool programs as a library and integrated with r_asm and r_bin.
.Pp
Programs generated by r_egg are relocatable and can be injected in a running process or on-disk binary file.
.Pp
ragg2-cc is another tool that comes with r2 and it is used to generate shellcodes from C code. The final code can be linked with rabin2 and it is relocatable, so it can be used to inject it on any remote process.
.Pp
ragg2-cc is conceptually based on shellforge4, but only linux/osx x86-32/64 platforms are supported.
.Sh DIRECTIVES
.Pp
The rr2 (ragg2) configuration file accepts the following directives, described as key=value entries and comments defined as lines starting with '#'.
.Bl -tag -width Fl
.It Fl a Ar arch
set architecture x86, arm
.It Fl b Ar bits
32 or 64
.It Fl k Ar kernel
windows, linux or osx
.It Fl f Ar format
select binary format (pe, elf, mach0)
.It Fl o Ar file
output file to write result of compilation
.It Fl i Ar shellcode
specify shellcode name to be used (see \-L)
.It Fl e Ar encoder
specify encoder name to be used (see \-L)
.It Fl B Ar hexpair
specify shellcode as hexpairs
.It Fl c Ar k=v
set configure option for the shellcode encoder. The argument must be key=value.
.It Fl C Ar file
include contents of file
.It Fl d Ar off:dword
Patch final buffer with given dword at specified offset
.It Fl D Ar off:qword
Patch final buffer with given qword at specified offset
.It Fl w Ar off:hexpairs
Patch final buffer with given hexpairs at specified offset
.It Fl p Ar padding
Specify generic paddings with a format string.
.It Fl F
autodetect native file format (osx=mach0, linux=elf, ..)
.It Fl O
use default output file (filename without extension or a.out)
.It Fl I Ar path
add include path
.It Fl s
show assembler code
.It Fl x
execute (just-in-time)
.El
.Sh EXAMPLE
.Pp
$ cat hi.r
/* hello world in r_egg */
write@syscall(4);
exit@syscall(1);
.Pp
main@global(128) {
.var0 = "hi!\\n";
write(1,.var0, 4);
exit(0);
}
$ ragg2 \-O \-F hi.r
$ ./hi
hi!
.Pp
.Pp
$ cat hi.c
main() {
write(1, "Hello\n", 6);
exit(0);
}
$ ragg2 hi.c
$ ./hi.c.bin
