# Assembleur
## Usage
```bash
./Assembleur [--help] [--version] [--output file] [--format type] file
```
There are 3 format types :
- "int" : 32 bits integers are written. Exemple : `10878976`
- "binint" (default) : bits are written. Exemple : `00000000 10100110 00000000 00000000`
- "bin" : the file is written in pure binary
## Exemple
```assembly
operations:
add R1 R2 R3
sub R1 R2 #69
and R0 R6 R3
xor R1 R2 R3
or R1 R7 R3
sl R5 R2 #10
sr R1 R2 R3
io:
str R1 R2 R3
ld R1 R2 R3
sauts:
jmp controle
jequ R1 R2 io
jneq R1 R2 sauts
jsup R1 R2 operations
jinf R1 R2 controle
controle:
call io
ret
```
