@ -8,16 +8,18 @@ A simple POSIX-based operating system for personal computers, written in C++. [!
- x86_64-compatible lightweight [kernel](kernel/).
- Preemptive multitasking, with a round-robin [scheduler](kernel/src/thread/).
- [Virtual file system](kernel/src/fs/) with a simple [tmpfs](kernel/src/fs/tmpfs/) and read-only [ext2](kernel/src/fs/ext2/) support.
- Can [load ELF programs](kernel/src/thread/ELF.cpp) from the file system as userspace tasks.
- Can [load ELF programs](kernel/src/binfmt/ELF.cpp), [shebang scripts](kernel/src/binfmt/Script.cpp) or [arbitrary binary formats](kernel/src/binfmt/BinaryFormat.h) (registered through kernel modules, which are not supported yet =D).
- Boots from an [ext2](apps/preinit.cpp) root filesystem (a bit slow for now).
- [System call](kernel/src/sys/) interface and [C Library](libc/), aiming to be mostly POSIX-compatible.
- [System call](kernel/src/sys/) interface and [C Library](libc/), aiming to be almost POSIX-compatible.
- Support for [several third-party programs](ports/), including the [GNU binutils](ports/binutils/PACKAGE) suite of utilities.
- POSIX [signal](libc/src/signal.cpp) support.
- Designed to be [portable](kernel/src/arch), no need to be restricted to x86_64.
- Designed around [UTF-8](libluna/include/luna/Utf8.h).
- Everything is [UTF-8](libluna/include/luna/Utf8.h).
- [UNIX local domain sockets](kernel/src/net/UnixSocket.cpp), allowing for local IPC.
- [POSIX shared memory](libc/include/sys/mman.h) support.
- Environment-agnostic [utility library](libluna/), which can be used in both kernel and userspace.
- Return-oriented [error propagation](libluna/include/luna/Result.h), inspired by Rust and SerenityOS.
- Build system uses [CMake](CMakeLists.txt).
- Return-oriented [error propagation](libluna/include/luna/Result.h), inspired by Rust and SerenityOS. No exceptions here :).
- An extensive set of [standard Unix utilities](apps/), from [ls](apps/ls.cpp) to [uname](apps/uname.cpp) to [base64](apps/base64.cpp). Written in modern C++ and very small amounts of code, using Luna's practical [OS library](libos/).
