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.mmap_min_addr + p_offset of first segment */
   
       .text : {
           * (.text)
       }
   
       .data : {
           * (.data)
       }
   }
   
   $ nasm hello_world.s -f elf64
   $ ld hello_world.o -o hello_world -n -T link.ld
   $ elfcat hello_world
   $ xdg-open hello_world.html
