### 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)

# The Design of AbleOS
## The unix philosophy and why it shouldn't exist
small is only beautiful if its complete.
grep for example supports the `-r` flag which should instead be `grep`+`find`
Everything is not a stream of bytes.
programs can do multiple things well
`cat`, `head` and `tail` could all be one program with a flag
`which head` `which tail` `which cat` should all return the same binary with different flags
```
which head == /bin/cat range=0-10
which tail == /bin/cat reverse_index=true range=0-10
which cat == /bin/cat
```
build a prototype quickly only applies if you are being pressured. do thing quickly then refine
'choose portability over effeciency' this is a flawed idealogy choose modularity over pure portability
'store data in flat text files' this leads to a psuedostandardization on KVPair configuration languages that all sit in a flat text file. Instead pick a configuration format that gets loaded into a tree structure
## File Systems
### The amount of files inside of a folder
32765. Why you might ask?
### Dot files
`dotfiles` were a mistake given to us by bad programmers mocking better programmers. [link](https://web.archive.org/web/20230413171520/http://xahlee.info/UnixResource_dir/writ/unix_origin_of_dot_filename.html)
### File name case sensitivity
Case sensitivity seems like a great idea! But in practice leads to the following filetree
```
/kernel
/Kernel
/kErnEl
/KeRnEl
```
which is a nightmare and you should be erradicated if you think this is a positive
provide a display name for files that allows case and save the file as caseless
### File name character limits
unix is a plauge upon this earth. name a file `:(){ :|:& };:` and try listing it. You have lost access to your terminal.
if you defined a sane method of listing files and allowing programs to provide the OS a standard method of providing argument suggestions and being aware you would never run into this issue
## CLI vs GUI
Graphics are not your enemy unix lovers. You mustn't be stuck in 1981. Times have changed! You can have a graphical shell enviroment. SGI Irix was aware of this in 1988, not perfect of course but 7 years after dos is an impressive leap.
FFMPEG??? Why no gui? Give me a good git ui
### Emails plain text
Unix believes in plain text emails. Quotes are `>`
### Unix Wizards and Instability
[Do not meddle in the affairs of Unix, for it is subtle and quick to anger.]
### Unix why are your mouse a file?
This list is incomplete
`/dev/input/event1` The PS2 Mouse
`/dev/input/event3` The USB Mouse
`/dev/input/psaux` The PS2 Mouse
`/dev/input/psmouse` The PS2 Mouse
`/dev/input/mice` The Not(?) PS2 Mouse I think?
`/dev/input/mouse0` The not Not(?) ps2 mouse? First usb mouse I think?
`/dev/input/usbhid` USB mice (should be autodetected)
`/dev/input/sermouse` Most serial mice
`/dev/input/logibm` Bus mouse connected to Logitech adapter card
`/dev/input/inport` Bus mouse connected to ATI or Microsoft InPort card
`/dev/input/by-id/usb-<usbid here>` A usb mouse via its id
I propose a unified system for input via a Device Tree of sorts

- Integrate HBVM
HBVM also needs full spec compliance
- Build out the object system
- Build or Find an acceptable IDL
Short List of potentials

# 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.
