# 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.

Bananarchy targets an ultra-lightweight **Sxmo X11 (`sxmo-de-dwm`)** environment (with all Wayland components removed) powered by a cross-compiled **Xlibre (`X11Libre/xserver` 25.2.0)** display server (`modesetting` KMS + `ShadowFB` Damage partial-rectangle SPI transfers, software cursor fallback, rootless `elogind`), **patched `sxmo-dwm`** (`240x320` vertical `bstack` layout, 24px Pango status bar with overflow-protected right-aligned clock, direct C `SW_LID` slider and locked-key wake handling in `< 2 ms`), **patched `sxmo-dmenu`** (`240x320` full-width 9-line vertical menu flush below the 24px top bar with `#383838` search bar, `#005577` prompt badge, and `XIM` `fcitx5-t9` text input in `< 15 ms`), **patched `sxmo-st`** terminal (`pixelsize=15`) with **HarfBuzz (`libharfbuzz`) OpenType ligature shaping** (`liga`, `calt`, `clig`, `dlig`) and `XIM` support, and **non-Nerd `Fira Code` (`font-fira-code`) with ligatures** as the primary system and terminal font (with `DejaVu SansM Nerd Font` used strictly as an icon fallback). It features a sub-95 MB idle RAM footprint on 512 MB devices, full Qualcomm QDSP6/Q6Voice audio (loudspeaker, earpiece speaker, and internal/headset microphones with PM8909 WCD analog codec 2.8V micbias and +6 dB EAR PA gain), GSM/WCDMA/LTE modem routing (`ModemManager` + `q6voiced`), rear 2MP camera support (`msm8905-cam` V4L2 driver for GalaxyCore `GC2395` + MSM8909 `CAMSS` on `/dev/video0` and `bananarchy-photo` CLI/Sxmo app), pre-integrated **Bantam** AI agent (`https://code.luxferre.top/luxferre/bantam-cpp`), a complete on-device development & scripting stack (`git`, `gcc`/`g++`, `make`, `nano`, `janet` + `jpm`, `perl` + `IO::Socket::SSL`, `tcl` + `tcllib`/`tcl-tls`/`sqlite-tcl`, `sqlite`, `i2c-tools`, `v4l-utils`), and a custom **6-mode `fcitx5-t9` input engine** with a fixed bottom candidate bar (`X=1, Y=290, W=238, H=30`) supporting lowercase, one-shot Shift, Caps Lock, all 32 ASCII punctuation symbols, terminal control codes (`^A`-`^Z`, `Esc`, `Tab`, `F1`-`F12`), and direct numeric entry with live top-bar mode indication (`[abc]`, `[Abc]`, `[ABC]`, `[Sym]`, `[Ctl]`, `[123]`).

The current Bananarchy version is `v0.0.1`.

## 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 (HarfBuzz Fira Code ligatures), sxmo-dmenu (XIM), and sxmo-dwm
./scripts/build-sxmo-x11.sh

# Rebuild multi-mode fcitx5-t9 input engine (src/fcitx5-t9 -> prebuilt/fcitx5-t9)
./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` (raw partitioned MBR image for EDL `userdata` or microSD card)
- `images/bananarchy-<device>.sparse.img` (Android sparse image for `fastboot flash userdata`)
- `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.
