Getting Started

Build with make ( version 4.3 )

$ make
$ make clean

Build with cmake badge ( version 3.19.7 )

    for linux
$ cmake -S . -B build/ -DCMAKE_BUILD_TYPE=Debug

    for windows
$ cmake -S . -B build/ -A x64 -G "Visual Studio 16 2019"

$ cmake --build build/ --config Debug
$ ./build/Assembler <source_file_path>

Build with docker badge ( version 20.10.6 )

Style Guide

Code Definition

OPCODE REGISTER,[REGISTER, MEMORY, IMMEDIATE]

# example
HRK AX, BX
    or
HRK AX, [<variable_name>]
    or
HRK AX, 10

Variable Definition

<variable_name>: <immediate>

# example
var1: 10
    or
var1: -10

Branching

<LABEL>: <NEWLINE>
    something
    <BRANCHING_OPCODE> <LABEL>

# example
LOP:
    TOP AX, 10
    SS LOP

Grammar ( ebnf )

program = field, { field };

field 
= [label],
  [variable],
  opcode, [register | memory_addressing | immediate]
  [',', (register | memory_addressing | immediate)] newline

label 
= STRING ':' newline;

variable
= STRING ':' immediate;

opcode
=  HRK
  |TOP
  |CIK
  |CRP
  |BOL
  |DEG
  |VE
  |VEYA
  |SS
  |SSD
  |SN
  |SP;

register 
=  AX
  |BX
  |CX
  |DX;

memory_addressing
= '[', ADDRESS, ']';

immediate
= { decimal };


decimal = { -128 ... +127 };

newline = { [\n] | [\r\n] };
