# Bananarchy Linux

![Bananarchy Banner](artwork/banner-800x240.png)

**Bananarchy** is a keypad-first Linux distribution hardforked from postmarketOS (`v26.06` / Alpine `edge` `armv7`), purpose-built for **Qualcomm MSM8905 (Snapdragon 205)** and **Qualcomm MSM8909 (Snapdragon 210)** smart feature phones with **240x320 QVGA non-touch displays** and **physical 12-key T9 keypads**.

See [The Bananarchy Manifesto](./MANIFESTO.md) for the rationale behind this entire project.

## Key features

### System & hardware support
- **Mainline Linux 6.12 kernel**: Custom patches and out-of-tree kernel drivers for Qualcomm QDSP6/Q6Voice audio routing, Dual-SIM modem control, the rear 2MP GalaxyCore `GC2395` camera (`/dev/video0`), `SY7807` torch LED (`white:torch`), and physical keypad/slider events.
- **Alpine Linux Edge base**: Full access to the Alpine package ecosystem with `< 95 MB` idle RAM usage on 512 MB devices.
- **Pure X11 graphical stack**: Cross-compiled **Xlibre** (`X11Libre/xserver`) display server paired with a heavily optimized **Sxmo (`sxmo-de-dwm`)** window manager (`240x320` vertical stack layout, `< 2 ms` slider/key wake latency, and zero Wayland overhead).

### Keypad-first user experience & native DWM plugins
Instead of spawning slow shell scripts for everyday phone tasks, Bananarchy runs a suite of preloaded resident C/C++ plugins inside DWM that open in `< 2 ms`:
- **System & context menus (`dmenu`)**: Instant full-screen 10-line vertical menus with live T9 filtering and built-in submenus.
- **Global controls drawer (`xdrawer`)**: Press **both softkeys together** from anywhere to adjust speaker/earpiece volume, ringer mode, flashlight, mic/sound mute, screen brightness, and keypad backlight.
- **Phone dialer (`xdialer`), call log (`xcalllog`) & call screen (`xcallscreen`)**: Press any digit on the home screen to start dialing with live T9 contact matching, run carrier USSD codes (`*100#`, etc.) interactively, or type `*#06#` to inspect both IMEIs. Incoming and active calls open a dedicated call screen with earpiece/speaker routing, microphone mute, DTMF keypad, and one-key call recording (`~/Recordings/`).
- **Contacts (`xcontacts`) & SMS manager (`xsms`)**: Full phonebook editor and threaded conversation/draft SMS manager with multi-tap keypad text entry.
- **Modem & Dual-SIM manager (`xmodem`)**: 4-tab cellular control center (`1:SIMs`, `2:Radio`, `3:AT`, `4:Log`) supporting physical SIM 1 / SIM 2 active slot switching, SIM PIN unlock and PUK unblock wizards, 2G/3G/4G mode selection, interactive USSD sessions, and a live AT command console.
- **Networks & Bluetooth manager (`xnetworks`)**: 3-tab connectivity manager (`1:Wi-Fi`, `2:Cell/APN`, `3:Bluetooth`) for Wi-Fi networks, WPA2 password entry, hotspot/USB tethering, mobile data & APN editing, and Bluetooth pairing.
- **File manager (`xfiles`) & camera (`xcamera`)**: Graphical directory browser with built-in text and image viewers, plus a live V4L2 camera viewfinder with digital zoom, flash/torch control, self-timer, and photo gallery.
- **Themes (`xthemes`), wallpapers (`xwallpapers`) & ringtones (`xringtones`)**: Installable `.Xresources` color/font themes (`~/.xthemes/*.xth`, 20 preinstalled schemes) with live zero-restart reload across the entire UI and terminal, alongside dedicated managers for desktop wallpapers and call ringtones/vibration.

### Input, terminal & developer tools
- **6-mode `fcitx5-t9` keypad input**: Cycle with `#` between `abc`, `Abc`, `ABC`, `Sym` (all 32 ASCII punctuation symbols), `Ctl` (`Ctrl` sequences, arrows, `PageUp`/`PageDown`, `F1`–`F12`), and `123` numeric modes with a fixed bottom candidate bar.
- **First-class Linux terminal (`st`)**: Patched with HarfBuzz OpenType ligatures (`Fira Code` as the default system and terminal font), XIM T9 input, and live theme reloading.
- **On-device development & AI**: Preinstalled `gcc`/`g++`, `make`, `git`, GNU `coreutils`, `nano`, `ed`, `sqlite`, `perl`, `tcl`, the [Janet](https://janet-lang.org/) language & `jpm`, the [Bantam](https://bantam.luxferre.top/) coding agent, `frotz` (interactive fiction), and standalone X11 keypad games (`Snake` and `Tetris`).

## Build & customization workflow

### 1. Regenerate artwork assets
Whenever `artwork/icon-large.png` is updated, regenerate all icons, `240x320` wallpapers, and boot splashes:
```bash
./scripts/generate-artwork.py
```

### 2. Recompile core components (optional — prebuilts included)
All components are pre-compiled in `prebuilt/` and `overlay/rootfs/`, and can be rebuilt from source at any time using rootless Docker (`alpine:3.24`):
```bash
# Rebuild cross-compiled Xlibre (X11Libre/xserver) + libinput/fbdev DDX drivers
./scripts/build-xlibre.sh

# Rebuild patched sxmo-st, sxmo-dmenu, sxmo-dwm & all 13 C++ DWM plugins
./scripts/build-sxmo-x11.sh

# Rebuild standalone X11 games (snake, tetris)
./scripts/build-games.sh

# Rebuild multi-mode fcitx5-t9 input engine
./scripts/build-fcitx5-t9.sh

# Fetch latest master from https://code.luxferre.top/luxferre/bantam-cpp and cross-compile Bantam AI agent
./scripts/build-bantam.sh

# Rebuild Linux 6.12.1-msm8916 QDSP6/Q6Voice audio modules, torch LED module, camera module & DTBs
./scripts/build-kernel-audio.sh
```

### 3. Customize rootfs packages or configs
```bash
./chroot-shell.sh
# Inside the container shell:
#   pkg-add <pkg>
#   pkg-del <pkg>
#   pkg-search <pattern>
```

### 4. Build flashable device images
```bash
# Build for Nokia 8110 4G (default)
./rebuild-image.sh nokia-argon

# Or build for Nokia 2720 Flip, Nokia 800 Tough, or Nokia 8000 4G:
./rebuild-image.sh nokia-beatles --mkinitfs
./rebuild-image.sh nokia-tough --mkinitfs
./rebuild-image.sh nokia-sparkler --mkinitfs
```
Output images are written to `images/`:
- `images/bananarchy-<device>.img` (partitioned MBR image for EDL `userdata`, `fastboot flash userdata`, or microSD card)
- `images/boot-bananarchy-<device>.img` (kernel + initramfs + DTB boot image)

---

## Flashing via USB EDL (`05c6:9008`)

```bash
sudo ./flash-edl.sh nokia-argon
```
See [MANUAL.md](MANUAL.md) for complete EDL, Fastboot, and microSD installation instructions, keypad navigation shortcuts, and the multi-mode T9 reference.
