# i686 toolkit
## How to build and run ?
1. Install the dependencies
- Python >=3.11.0
2. You can just run the scripts in `scripts/`.
3. You can use install the Python module.
```bash
python setup.py install
```
## Usage example
#### Build and dump/save a GDT
```python
from ostools.gdt import Gdt
from ostools.gdt import GdtEntry
from ostools.gdt import GdtAccessByte
from ostools.gdt import GdtFlags
from ostools.gdt import CpuPrivilevel
a = Gdt() \
.add_entry(
GdtEntry("gdt_code")
.set_access_byte(
GdtAccessByte(0x9a)
)
.set_flags(GdtFlags())
) \
.add_entry(
GdtEntry("gdt_data")
.set_access_byte(
GdtAccessByte()
.set_p(True)
.set_dpl(CpuPrivilevel.RING0)
.set_s(True)
.set_rw(True)
)
.set_flags(0xcf)
) \
.add_end() \
.add_descriptor() \
.dump_asm() # or .save_asm("test.asm")
```
#### Convert a Linux PC Screen Font to x86 assembly data
```python
from ostools.psf import Psf
a = Psf("ter-v32n.psf") \
.parse() \
.save_asm("test.asm")
```
## Scripts
The directory `scripts/` contains scripts intended to do metaprogramming. Most of them concern the 32 bits interrupts.
