 🍱 bento (弁当) 

A collection of macros intended at making assembly more convenient to write and a bit closer to C. Only for x86_64 linux and the FASM assembler (for now).


 Example: 


```asm

format ELF64 executable 3

include 'bento.inc'

segment executable readable

entry $

  @mkstr hello_world, <"Hello, World", 0>

  @mkstr nums, "123456789"

  xor eax, eax

  .if (eax = 0)

    @iter1 r8, 0, 9

      @iter2 rax, 0, 9

        @iter3 rbx, 0, 9

          mov qword [dummy], rbx

          add qword [dummy], 48

          write STDOUT, dummy, 1

        @done3

        write STDOUT, newline, 1

      @done2

      write STDOUT, newline, 1

    @done1

  .endif

  puts hello_world

  exit 0

@@

segment readable writeable 

dummy: dq 0

newline: db 0xA

```

compile with:


```

$ fasm main.s

$ ./main

```
