vasilito 121ad07561 tlc: comprehensive feature batch — syntax highlighting, jobs/panelize/vfs dialogs, bug fixes
Editor:
- Wire syntect Highlighter into Editor::render() with viewport scroll
  state replay and selection-aware span splitting
  (split_spans_for_selection helper)
- F5/F6 escape sequence fallback parser (parse_unsupported_fkey)
  handles CSI-tilde, SS3, and Linux console F-key encodings
- Arrow key cursor sync (Option B — every move_*/select_* syncs buffer)
- ESC no-op on main screen (MC parity, F10 only exit)

FileManager:
- Background jobs dialog (Cmd::Jobs / C-x j) with Arc<Mutex<JobRegistry>>,
  worker threads, progress bars, retry, dismiss — zero unsafe
- External panelize dialog (Cmd::Panelize / C-x !)
- VFS list dialog (Cmd::VfsList / C-x a)
- Dialog consistency: MkDir/Delete now use render_button_row
- Panel cursor starts on first entry (index 1, not ..)
- Command execution returns immediately (no pause/prompt)
- Confirm dialog, sort dialog modules
- Backspace navigates to parent dir (MC parity, already worked)

Viewer:
- Magic number detection module
- NROFF backspace-overstrike rendering for man pages

Binaries:
- tlcedit (standalone editor, 1.2 MB)
- tlcview (standalone viewer, 661 KB)

Docs:
- PLAN.md §14 parity tables reconciled with comprehensive audit
- README.md updated: 109 files, 43k lines, 902 tests, 3 binaries

Stats: 902 tests pass (default), 920 (all features), 0 failures, 1 pre-existing warning

Red Bear OS

Red Bear OS

A microkernel operating system written in Rust, derived from Redox OS

MIT x86_64 Status


What is Red Bear OS?

Red Bear OS is a general-purpose, Unix-like operating system with a microkernel architecture, written in Rust. It is a full fork of Redox OS, frozen at release 0.1.0, with added hardware support, filesystem drivers, and a KDE Plasma desktop path.

Goals:

  • AMD & Intel parity — first-class support for both platforms on bare metal
  • KDE Plasma desktop — Wayland-based desktop environment via the KWin compositor
  • Hardware GPU acceleration — AMD GPU (amdgpu) and Intel GPU drivers via redox-drm
  • Modern subsystems — USB, WiFi, Bluetooth, ext4, GRUB, D-Bus
  • Offline-first builds — reproducible from archived, BLAKE3-verified sources

Quick Start

Prerequisites

Linux x86_64 host with Rust nightly, QEMU, nasm, and standard build tools.
See the Redox Build Guide for full setup.

Build & Run

# Clone
git clone https://gitea.redbearos.org/vasilito/RedBear-OS.git
cd RedBear-OS

# Recommended: use the Red Bear wrapper
./local/scripts/build-redbear.sh redbear-mini     # Text-only target
./local/scripts/build-redbear.sh redbear-full     # Desktop-capable target

# Boot in QEMU with the resulting image
make qemu

Build script: local/scripts/build-redbear.sh is the canonical entry point. Bare make all works but bypasses the .config checking and REDBEAR_ALLOW_PROTECTED_FETCH=1 gates that build-redbear.sh enforces. See AGENTS.md § Build Commands for full details.

Public Scripts

Script Purpose
local/scripts/build-redbear.sh Canonical build wrapper for redbear-mini/full/grub
scripts/run.sh Build and run in QEMU (-b to build, -c <config> for target)
scripts/build-iso.sh Build a live ISO for bare-metal boot
scripts/build-all-isos.sh Build all live ISO targets
scripts/network-boot.sh PXE network boot helper
scripts/dual-boot.sh Dual-boot installation helper

Config Targets

Target Type Description
redbear-full Desktop Wayland + KDE + GPU drivers + D-Bus services
redbear-mini Console Text-only recovery / install target
redbear-grub Console Text-only with GRUB boot manager

Current Status

Red Bear OS boots to a login prompt in QEMU with working wired networking, D-Bus system bus, hardware detection daemons, and filesystem support (RedoxFS, ext4, FAT).

Area Status
Boot (ACPI/x2APIC/SMP) Bare-metal proven
Userspace drivers (PCI, storage, net) Working in QEMU
D-Bus system bus + services Working (login1, PolicyKit, UDisks, UPower)
ext4 / FAT filesystems Compiles, installer-wired
POSIX gaps (relibc) 🚧 Bounded Wayland-facing support
DRM/KMS display drivers 🚧 AMD + Intel compile; HW validation pending
Wayland compositor 🚧 Bounded proof; Qt6/KF6 clients crash at init
KDE Plasma desktop 🔄 In progress (Qt6/KF6 compile; KWin/QML blocked)
WiFi / Bluetooth 📋 Planned (architected, implementation pending)

How It Works

Red Bear OS uses a userspace driver model — all drivers run as unprivileged daemons:

Kernel (microkernel)
  └── schemes: memory, irq, event, pipe, debug
        └── Driver daemons (userspace)
              ├── pcid        → PCI enumeration
              ├── e1000d      → Intel ethernet
              ├── xhcid       → USB controller
              └── vesad       → Display framebuffer

The kernel provides minimal services (memory, interrupts, IPC). Everything else — filesystems, networking, graphics, input — runs in userspace.

Red Bear OS uses a full fork model. Upstream Redox sources are frozen and archived. All custom work lives in local/:

We welcome contributions made with or without AI assistance — we care about quality, not how the code was produced.
