### What are the requirements?
- A machine with [Rustc Tier 1 platform support](https://doc.rust-lang.org/nightly/rustc/platform-support.html#tier-1-with-host-tools)
- Rustup
- QEMU (for executing)
- GIT CLI
### How do I run ableos?
- It is recommended to run ableos under QEMU. Here is how:
- Install QEMU
- Clone ableos
- Go to ableos directory
- Pull the limine submodule with `git submodule update --init`
- Run `cargo repbuild help`
### How can I contribute?
- [Contribute code](#how-do-i-contribute-code)
- [Run ableos on your machine](#how-do-i-run-ableos)
- Find bugs
- Create media showing ableos
### How do I contribute code?
- Start by forking ableos
- Write something that runs in the userspace, for example:
- System drivers
- Programs
- Libraries
- Patch bugs and improve code in the kernel
- Ensure that the code is OK to be maintained by asking in the [discord](https://discord.gg/t5Wt3K4YNA)
- When you have finished your changes, you can submit a pull request for review [here](https://git.ablecorp.us/ableos/ableos)
### repbuild and kernel compile, but QEMU isn't starting
- Ensure you have the `qemu-desktop-{arch}` for your OS and target architecture installed
- Try running again with `--noaccel` if you have QEMU already
### I have run using repbuild but it's slow
- Ensure release mode is enabled with the `-r` flag
- Remove the `--noaccel` flag if you can
- If both of these are already done, there may be a problem with thee VM, kernel, your program, or the hblang compiler
### Compiler is complaining about "reg id leaked"
- [Submit](#how-do-i-report-a-compiler-bug) an issue, reg id leaked is a bug
### My program isn't running
- Refer to [here](#i-have-run-using-repbuild-but-its-slow), it may be that your program is simply starting slowly
- Ensure that your program has a properly written meta.toml file
- Ensure that your program is enabled in [system_config.toml](sysdata/system_config.toml)
- Try running again with `--noaccel`, there is a known bug with some systems that prevents programs from starting.
### Kernel panic??? Huh???
- Kernel panics can be caused by improperly using memory (e.g, writing out of bounds)
- Kernel panics are most likely to be caused when accessing memory or using `@eca` for kernel ecalls
- [Report](#how-do-i-report-an-ableos-bug) a kernel panic
### I am running in release mode but I have no debug info
- Add the `-d` flag for debug info
### What is `@eca`? How do I use it?
- Eca is an ecall. They are similar to syscalls
- The `@eca` directive takes the following arguments:
- `@eca(ecall_number, reg_1, ..., reg_n)`
- The various ecalls have different arguments that are given by register values
- Most ecalls are wrapped by `stn`, for example, `random`, `buffer`, and `memory` all make use of ecalls
- All ecalls can be found [ecah.rs](kernel/src/holeybytes/ecah.rs)
### How do I report an ableos bug?
- Submit an issue [here](https://git.ablecorp.us/ableos/ableos/issues) or report it in the [discord](https://discord.gg/t5Wt3K4YNA)
### How do I report a compiler bug?
- Submit an issue [here](https://git.ablecorp.us/ableos/holey-bytes/issues) or report it in the [discord](https://discord.gg/t5Wt3K4YNA)

# AbleOS
An UNIX-unlike micro-kernel written in rust with an embedded bytecode virtual machine.
Please note that a custom target directory is not supported and support will not be added.
```
TODO
- Integrate HBVM
HBVM also needs full spec compliance
- Build out the object system
- Build or Find an acceptable IDL
Short List of potentials
- [comline](https://git.ablecorp.us/DOOME1M8Cover/comline)
- Work on a styleguide for commits
Maybe something allong the lines of
[relevant shorthand note] Explination
- Build a scheduler for HBVM
- Language support on HBVM
- HBVM assembler (with IDL support)
- HBVM Lisp/s-expr Compiler (Also (with (IDL (support))))
- Documentation
- Drivers
- serial driver
- PS/2 mouse driver
- PS/2 Keyboard driver
- VGA driver
- SVGA driver
- File system
TarFS
Pass in a tar file as an initrd and parse it with TarFS
- VFS
Being (written)[https://git.ablecorp.us/bee/ableos-vfs] by Bee
- Disk driver
- A ton more

# Compiling
See [HELP.md](HELP.md)
Firstly, I would like to apologize. I am not capable of supporting building on any random machine with any random operating system.
# Developing
There is a new work in progress developer tool for hblang. (see: dev folder)
AbleOS very likely builds with `nix-shell` on your operating system.
1. `git submodule update --init`
1. `cargo repbuild`

STYLE_GUIDE.md

# Style Guide
This style guide has two modes that a guideline may be.
`strict` means that prs will be rejected if they do not follow the guideline.
`loose` means that a pr would be accepted but should later be fixed.
## Empty Functions | loose
Empty functions are typically a sign of an unfinished program or driver.
In cases where there is a clear reason to have an empty function it will be allowed.
For example FakeAlloc is only empty functions because it is a example of an the allocator api.
### Allowed
```rust
/// in example.hb
a := fn(): void {}
```
### Not Allowed
```rust
/// in fat32.hb
a := fn(): void {}
```
## Magic Functions | loose
'Magic functions' are what I am calling small helper functions that do one or two things.
### Example
```rust
a := null
magic_a := fn(){
a = 10
}
```
The exact policy I want to have here is a bit fuzzy. I think that functions like this are nice in certain situations and not in others.
Regardless of if you use them or not, put a comment above the function explaining rational.
## Magic Numbers | loose
The policy on magic numbers is make them const and have a comment above them. Typically linking to a source of information about the magic number.
This helps cut down on magic numbers while making acceptable names and atleast half assed documentation.
Constants are inlined anyways, so its the same thing in the binary.
```rust
// The standard vga port is mapped at 0xB8000
$VGA_PTR := 0xB8000
```
## Tabs Vs Spaces | strict
I prefer for hblang code to use hard tabs.
The rational behind this is that a tab is `1 Indent` which some developers might want to be various different sizes when displayed
Soft tabs do not allow this user/editor specific as soft tabs always become spaces.
Bottom line is this is an accessibility feature.
There are some samples below.
```
\t means hard tab
\n means new line
\0x20 means space
```
### Allowed
```rust
if x == y {\n
\tlog(z)\n
}\n
```
### Not Allowed
```rust
if x == y {\n
\0x20\0x20\0x20\0x20log(z)\n
}\n
```
