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. How does it look like?

    This is how 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

 3. Can I contribute?

    Of course!

 4. License?

    Zlib.

 5. When I try this on huge files, it slows down my browser!

    Sorry about that. There used to be a feature where segments and
    sections would be collapsed into a couple characters instead of
    showing full contents, but it was disabled because it:

      + broke when these would overlap

      + in a way, defeats the purpose: seeing specific bytes is a
        feature.

 6. Upcoming features?

      + Ability to tune the width instead of hardcoded 16 bytes

      + Visualization of virtual memory mappings

      + Dark theme

      + Highlight bytes in ASCII column
