This is my hobby operating system written in C++. Currently supports only x86\_64 architecture. We have a ext2 filesystem, basic ramfs, IDE disk drivers in ATA PIO mode, ATA AHCI drivers, userspace processes, executable loading from ELF format, linear VBE graphics and multithreaded processing on single core.
## Code structure
Each major component and library has its own subdirectory (kernel, userspace, libc, ...). Each directory contains directory *include*, which has **all** of the header files of the component. Every header is included by its absolute path.
> ***NOTE:*** You need cmake version of atleast 2.26. If you are using cmake that is not found from PATH, you can set the CMAKE\_COMMAND environment variable to point to the correct cmake binary. Or you can let build script download correct version of cmake if you don't have one.
When you clone this reposity, make sure to also clone submodules. This can be done by cloning with the command ```git clone --recurse-submodules https://git.bananymous.com/bananymous/banan-os.git``` or if you have already cloned this repo, run ```git submodule init && git submodule update```.
If you have corrupted your disk image or want to create new one, you can either manually delete *build/banan-os.img* and build system will automatically create you a new one or you can run the following command.
If you feel like ```./script/build.sh``` is too verbose, there exists a symlink _bos_ in this projects root directory. All build commands can be used with ```./bos args...``` instead.
I have also created shell completion script for zsh. You can either copy the file in _script/shell-completion/zsh/\_bos_ to _/usr/share/zsh/site-functions/_ or add the _script/shell-completion/zsh_ to your fpath in _.zshrc_.
Currently I don't accept contributions to this repository unless explicitly told otherwise. This is a learning project for me and I want to do everything myself. Feel free to fork/clone this repo and tinker with it yourself.
