elfcat - ELF visualizer. Generates HTML files from ELF binaries.

1. How do I install and use it?

   $ cargo install elfcat $ elfcat path/to/file

2. What does it look like?

   This is what the following small example ELF file looks like:

   http://ruslashev.github.io/elfcat/hello_world.html

   Steps to create it:

   $ cat hello_world.s global _start

   section .text _start: mov rax, 1 mov rdi, 1 mov rsi, msg mov rdx, len syscall

      mov rax, 60
      xor rdi, rdi
      syscall
   

   section .data msg db "Hello, world!", 0xA len equ $ - msg

   $ cat link.ld ENTRY(_start)

   SECTIONS { . = 0x10080; /* vm.mmapminaddr + p_offset of first segment */

      .text : {
          * (.text)
      }
   
      .data : {
          * (.data)
      }
   

   }

   $ nasm helloworld.s -f elf64 $ ld helloworld.o -o helloworld -n -T link.ld $ elfcat helloworld $ xdg-open hello_world.html

3. Can I contribute?

   Of course!

4. License?
