# AbleOS
An UNIX-unlike micro-kernel written in rust with an embedded bytecode virtual machine.
# ableOS
![Discord](https://img.shields.io/discord/831368967385120810) ![Code Size](https://img.shields.io/github/languages/code-size/abletheabove/ableos)
## Set up
Install [Qemu](https://www.qemu.org/)
Please note that a custom target directory is not supported and support will not be added.
> On Windows be sure to add `C:\Program Files\qemu` to your `PATH` variable

# Compiling
AbleOS should be able to be built on any platform which is supported by
[Rustc Tier 1 platform support](https://doc.rust-lang.org/nightly/rustc/platform-support.html#tier-1-with-host-tools).
`cargo install bootimage`
For running AbleOS, `repbuild` uses QEMU.
## Steps
1. Ensure you have qemu installed
2. `git submodule update --init`
3. `cargo repbuild run`
## Running
repbuild can be used to run and build docs for able os
# Developing
There is a new work in progress developer tool for hblang.
`cargo repbuild doc`
`cargo repbuild run`
## Testing on real hardware
I recommend using an old x86_64 computer
* `cargo run --release` to generate a binary image that is bootable
* flash it to a USB device via `dd` or balenaEtcher
* Remove said USB device and plug into test machine
* assure test machine boots from USB devices
